Many improvements and new features for WatchMouse users (2005-01-31)

The last few months many improvements were made and new features were added to the WatchMouse service.
All new features are available for current and new subscribers at no extra charge.

The major improvements and features are listed below:

• New feature: A message log, which allows you to see the date, time, type and destination of all notifications that have been sent to you or your colleagues.
• Update of the logs access page: listing of WatchMouse members who have given you access to watch their log files and graphs, and the option to remove them from your list.
• Addition to the member details page: Financial contact details for invoicing can now be stated explicitly.
• Major improvement to the log file viewer: both scheduled and extra checks (in case of a triggered rule or an user initiated check) are shown in the log files as well as the second opinion checks.
• Improvement of the user interface of the rule settings: introduction of a simple mode and expert mode. The rule wizard is removed
• Much requested feature: the time-out for a rule can now be specified by the user in the rule settings page (expert mode).
• You can now have many inactive rules, in addition to your active rules. This is no longer limited by the maximum number of rules for your subdowntime alerting pagingion.
• For journalists only a press update service has been added.
• Many, many small (and big) improvements "under the hood".

As always: if you are missing a feature, please let us know! We will most likely add it in the next release.

LB Icon chooses WatchMouse for independent website monitoring (2005-01-31)

Customer websites verified from the visitors' perspective

LB Icon and WatchMouse have signed a contract for the continuous monitoring of the websites and services of LB Icons' customers. Using the WatchMouse services, LB Icon expects to raise its service level even higher.

The Application Management & Hosting Services (AM&HS) group of LB Icon maintains the administration and management of servers and applications of a large number of (international) clients. This makes AM&HS responsible for the performance and availability of the websites and Internet applications.

Using the WatchMouse services, AM&HS will instantly be aware of upcoming and/or acute incidents related to the websites of its clients, and can, as a result, resolve problems in a short time frame.
The websites and their functionality are checked for accessibility, speed and conformance from different locations around the world. Because the websites are checked in the same way that visitors are experiencing them, incidents will be detected at an early stage. Also, using WatchMouse's objective periodical reports, it is possible to see if the performance is in accordance with the agreed service levels (SLAs).

Eveline Aendekerk, MD a.i.: "The door of a shop should never be jammed, websites and the functionality on those sites should simply be accessible and available. Our clients should be able to rely on this completely, so they can focus on their primary business processes, such as communication, interaction and sales.
We chose WatchMouse because of their expertise, and also because of the simplicity and user-friendliness of their system and services".

Stan P. van de Burgt, one of the founders of WatchMouse: "I find it a powerful gesture that LB Icon doesn't just monitor the websites of their clients, but that they selected an external party for this, and on top of that give their clients access to the results. Many companies where the website plays an essential role in business, don't have any awareness of this. They have no idea of the risks and the resulting damage, until the day comes that things actually go wrong"

European e-commerce sites poorly prepared for Christmas rush (2004-12-24)

Comparison with US "role models" Amazon and Barnes & Noble

THE NETHERLANDS, 20041223 -- Many European e-commerce sites have made only minimal preparations for the increased number of visitors in December. The congestion caused by Christmas meant that, on average, only one in six web sites was continuously available. This was the conclusion of WatchMouse, a Dutch monitoring service provider, following a survey of over 50 European e-commerce sites. Excessive interest from customers can overload the server or have dramatic effect on response times.

During the past month, WatchMouse – at its own initiative – closely monitored over 50 web sites where consumers can shop online. The survey shows that the availability varied from 98% to 99.6%. "This may seem high, but a score of 98% means that a site is not available for half an hour per day. This makes 14 hours a month, or a week a year", says Mark Pors, one of the founders of WatchMouse.

As a comparison to the US market, two "role models of e-commerce" - amazon.com and barnesandnoble.com - were monitored during the same period. Amazon`s performance was similar to that of the average European web shop, whereas Barns & Noble outperformed most e-commerce sites with an uptime of 100%.

The consequences of downtime alerting paging are reflected not only in loss of income. Pors: "A website that is not available can cause stacks of work for your helpdesk and, at the end of the day, damage your brand. The problem is that many website owners are unaware that sites are responding poorly, or not responding at all. If they were aware of this, taking action to intervene is simplicity itself: for example, by adding extra server capacity."

WatchMouse has concluded from its survey that more than 70% of the web sites have not achieved optimum accessibility. Given the increasing trend in online purchases, gigantic sums are involved: Online sales will increase by 44% to €13 billion ($17 billion) in Western Europe over the holidays period, compared to €10 billion ($13 billion) in the US (Forrester Research, November 2004).

December is a top month for purchasing on the internet. Pors: "We see response times and the number of error reports increase dramatically in the days leading up to Christmas."

Companies can easily monitor their internet sites themselves, thanks to WatchMouse’s monitoring service.

WatchMouse has been monitoring internet sites and e-commerce applications for companies across the globe since 2001. WatchMouse has thousands of customers in more than 70 countries. WatchMouse services are available in seven languages, and analyses are carried out through the world-wide monitoring network from a range of locations and networks.

WatchMouse publishes first 'Site Availability Index' (2005-06-28)

Only 9 out of 25 funds listed on the Amsterdam stock exchange have sites with good availability

Of the websites of the 25 funds listed on the Amsterdam stock exchange (AEX), only nine display optimal availability. The availability of the other sites, including those of multinationals, ranges from poor to dramatically poor. Unilever has the best result of all websites, with an uptime of 99.995%. The site with the lowest availability is that of Wolters-Kluwer, with an uptime of 94.80%, which represents more than 37 hours of poor performance, or even unavailability, per month. This was the conclusion drawn from the first Site Availability Index created by WatchMouse, a company supplying monitoring services for websites and e-commerce applications world-wide.

An uptime of 99.9% is seen as the minimum acceptable level. This percentage is also often quoted in service level agreements (SLAs) with hosting providers. In order to determine the extent to which the sites of AEX funds achieve satisfactory uptime, WatchMouse monitored the sites for more than two months. Downtime was said to occur if a site was not available or did not respond within 8 seconds.

The Site Availability Index for AEX funds (www.watchmouse.com/bereikbaarheidsindex/2005/AEX.html) showed that only nine funds fulfilled the minimum required level of 99.9%. These were Unilever, Philips, AEGON, Numico, Akzo Nobel, ASML Holding, Kon. P&O Nedlloyd, Versatel and Buhrmann. Bringing up the rear were IT company(!) Getronics (96.87%), DSM (96.75%), and Wolters-Kluwer, which with a score of 94.80% is over a day and a half a month ‘off the air’.

The Site Availability Index for AEX funds is an initiative of Emerce and WatchMouse and will be repeated annually.

"Very surprised"

Mark Pors, chief technology officer at WatchMouse, stated that he was "very surprised" by the results. "With many sites, we found an uptime that is worse than that of many smaller companies. And this while AEX funds in particular should attach a great deal of priority to their corporate image. A maximum uptime is part of the 'brand performance'. Our theory is that, where there are a lot of people involved within an organisation, there are a lot of hands unplugging cables, so to speak. These companies have complex processes, a great many internal changes are made, and outsourcing of various activities means transparency is often at a premium. This is clearly the case with Getronics, for example. The uptime of the site at the weekend is 100%, but during the week, when people are working, this decreases dramatically."

Pors suspects that the popularity of the sites could also be a reason for poor availability. "Naturally, sites belonging to AEX funds get a lot more traffic than the smaller businesses. On the other hand, this is no excuse; if we look at large online brokers in the US, for example, all achieve an uptime in excess of 99.9%."

Rapidly growing WatchMouse wins Deloitte’s Rising Star award (2005-09-23)

WatchMouse is one of the three winners of Deloitte’s Rising Star award. This award is presented annually to rapidly expanding technology companies less than five years old. WatchMouse has been active downtime alerting paging downtime alerting paging alerting paging paging for three years in the area of site and server monitoring. With 16 monitoring stations throughout the world, WatchMouse monitors the availability of customers’ websites, immediately sounding the alarm in the event of problems.

The Rising Stars are presented as part of the Deloitte Technology Fast 50 ceremony, the fifty most rapidly expanding technology businesses. The Rising Stars have the potential to lead the Technology Fast 50 in the near future. Stan van de Burgt (42), Niels Eijsbroek (40) and Mark Pors (38) first came up with the idea for WatchMouse in 2001. The concept was as unique as it was clear: to monitor the availability of sites and servers by constantly simulating web traffic. If a site is not responding or an error is found, the customer is notified immediately by SMS, pager, IM or e-mail. From the moment the concept went 'live', in 2002, the pace has been frenetic: turnover doubled each year. Web sites are now monitored from sixteen monitoring stations downtime alerting paging downtime alerting paging alerting paging paging 24 hours a day, seven days a week.

The WatchMouse application is entirely web-based: customers do not have to install software or hardware at their site, and the application excels in its self-service aspects while staying easy to use. This allows WatchMouse to operate with a small core of permanent employees, supplemented by external support. Prospective customers can specify their requirements in detail on the WatchMouse site. A range of starter packages is available, priced from € 17.50 per month up to € 450 per month. 400 paying customers in 40 countries downtime alerting paging downtime alerting paging alerting paging paging now make use of WatchMouse’s services. These include hosting companies, government bodies, and companies such as LB Icon, Scania, Siemens, Orange, ING, GeoTrust, Citibank, and Postbank.

Self-service as a success factor

Mark Pors, Chief Technology Officer, says he was “pleasantly surprised by the award”. “I am very happy that the jury shares our vision of self-service and our market approach." Pors sees WatchMouse as “the right initiative at the right moment. Companies are increasingly looking to outsource non-core tasks. However, they want to be able to guide and control this themselves and from their own workplace. Web-based services make this possible." Stan van de Burgt, CEO, sees the simplicity of the WatchMouse site and the various languages in which it is available as the major success factors. "Monitoring websites was an idea that already existed in essence, but had not been worked out in this form. We are geared tightly to 'self service', whereby customers can set up everything themselves and retain total control. Which also means we are able to offer the service at a more attractive price than other players in the market.”

The Rising Star awards were presented on Thursday, 22 September.

Meerderheid e-commerce sites kan komende kerstdrukte niet aan (2009-05-14)

WatchMouse voorziet wachtende e-shoppers

UTRECHT 20051201 -- Nu de decemberinkopen weer in alle hevigheid zijn losgebarsten, blijken veel online shops regelmatig 'gesloten' te zijn. Dat concludeert WatchMouse in haar jaarlijkse bereikbaarheidsonderzoek van cadeausites. Het Nederlandse sitemonitoringbedrijf heeft net als vorig jaar een onderzoek gehouden onder webwinkels. Slechts drie sites in het onderzoek haalden de maximale 100%. Het merendeel haalt zelfs niet de score die door hosting providers wordt aangehouden als absoluut minimum.

Veel sites zijn maar matig voorbereid op grote aantallen bezoekers. Door de grote belangstelling raken servers regelmatig overbelast. Ook blijken reactietijden van sites dramatisch dalen. Het onderzoek dat WatchMouse in de weken voor Sinterklaas heeft gehouden, laat duidelijk zien dat sites problemen vertonen naarmate er meer bezoekers in de webwinkels verschijnen.

Om te controleren of e-commerce sites goed bereikbaar zijn, heeft WatchMouse de hele maand november controles uitgevoerd. De uptime bleek regelmatig onder de 99.9% te liggen, een grens die in veel service level agreements (SLAs) van hosting providers geldt als minimum. Dat percentage wordt maar door tien van de 25 sites gehaald. Neckermann, Bonaparte en eBay zijn de enigen met een score van 100%. Vorig jaar waren er nog zes sites die een maximale uptime haalden.

De bereikbaarheid van Kijkshop, Bart Smit, de Bijenkorf en Wehkamp blijkt verre van optimaal. De score van Wehkamp, 97.27%, betekent bijvoorbeeld dat deze site per dag meer dan een half uur slecht bereikbaar is.

De grootste stijger was Bonaparte (kleding) die van de 17e plaats in 2004 steeg naar een gedeelde eerste plaats. eBay bleef als enige twee jaar achtereen op 1. De grootste daler was ECI die van een gedeelde eerste plaats in 2005 naar de 23ste plaats zakte.

In het licht van de toenemende bestedingen online kan de economische schade voor een site groot zijn. In de eerste zes maanden van dit jaar is er online ruim een miljard euro besteed, concludeert de Thuiswinkel Markt Monitor 2005. De online bestedingen maken met 37% ten opzichte van dezelfde periode vorig jaar bovendien een snelle groei door.

Consument gewend aan snelheid

"In vergelijking met vorig jaar zijn effectieve maatregelen uitgebleven", zegt Mark Pors, CTO van WatchMouse. "Consumenten zijn gewend aan snelheid op internet. Moeten ze wachten op een site, dan blijken ze zeker voor decembercadeaus gemakkelijk naar een andere site te gaan. Veel bedrijven weten echter niet dat hun sites matig bereikbaar zijn.”

Opvallend zijn verder de sites die 100% halen. Pors: “Twee van de drie blijken in het buitenland gehost te worden. Waarschijnlijk is men in de VS (eBay) en Duitsland (Bonaparte) wel gewend de sites goed te dimensioneren”.

Vorig jaar bleek de kerstperiode overigens nog drukker dan de periode voor Sinterklaas. Om die reden zal WatchMouse ook in de weken voor kerst blijven monitoren. Vlak voor kerst verwacht WatchMouse met de resultaten te komen van die tweede testperiode.

Het onderzoek liep van 1 t/m 30 november 2005. Van 'downtime alerting paging' is sprake als een site een foutmelding geeft of de HTML na acht seconden niet ontvangen is, en dit vanuit een tweede meetpunt bevestigd is. Het complete bereikbaarheidsonderzoek is te vinden op: http://www.watchmouse.com/availabilityindex/2005/eshops_NL.php

What do you want to check with a service such as Watchmouse? (2005-01-31)

As I explained in my previous column, you can use a monitoring service in a number of roles. Common to all these roles is the fact that you are keeping alive some services for the benefit of your customers, suppliers, employees or partners. These users are, in the end, all that counts.

What are the objects that you should be checking? Obviously, the least you want to do is check the service that is most visible to these users. This could be the webserver, or a POP or FTP server for example. You would start by setting up a rule to check the server and a URL. The frequency with which you can monitor (that is: the elapsed time between checks) is typically limited by the type of subscription that you have. Only in specific cases would you not check as often as your subscription allows.

Note that there is a difference between a CONNECT on port 80 rule and a HTTP rule. The first just connects to the port that the webserver is supposed to use. The HTTP rule also checks whether the webserver can produce a valid HTTP response, and whether the document can be found. You probably want the latter check.
Similar reasoning applies to POP and FTP checks. If you set up two different rules on the same host, this allows you to distinguish for example between a broken webserver and a host that is down. If you want even more content oriented checks, have a look at the so-called PLUG-IN rules. Additionally, you can set up checks to make sure that your users are actually using the services that you intend them to. The whole Internet depends heavily on the domain name system(DNS) functioning correctly. If it does not work properly your users may be directed to another site than you intended. This could be a configuration error, but it could also be a defamation hack. In either case, you want to know.
First of all you want to check whether the root servers of the Internet accurately find the DNS that is serving you. This can be checked with a DNSNS rule. What you are checking with this rule is whether the registrar's databases are correct. Second, you want to check if that DNS server (and its slaves) are serving up the proper IP address for the server. For this you can use the DNSA rule, and it will warn you if the DNS server is not working or serves up the wrong address. (Note that the hosting party can change that address at its discretion, as part of a renumbering operation for example.)

Who should you notify of rule failures? Again, different roles have different information requirements. You want to notify the person who can fix things as soon as possible. Mail or SMS/text them directly, you do not want to be in the loop. You might set up an downtime alerting paging chain, which fires off after a certain amount of errors. Note: make sure that you send the message on a channel that is not affected by the outage: if your e-mail system does not work, delivering a message to that effect should not depend on that e-mail system.
The people in charge of overseeing somebody else's service levels should only get downtime alerting paging messages, if at all. Rather, they should get the weekly or monthly service reports.

Why do you need a monitoring service such as Watchmouse? (2005-01-31)

There are a number of reasons for this, depending on your role in your organization, and what you want to achieve. Each of these roles leads to a different approach for using and setting up the service.

Most likely you are either responsible for keeping a service such as a website online, or you have contracted somebody else to do that for you. Additionally, you could be a consultant or technical architect who wants to get an insight in downtime alerting paging and uptime characteristics of various solutions and services.

If your role is to keep things running, you really want to be notified of problems as soon as possible, before your customers or supervisors notice. You want appropriate error messages and not too many false alarms. As you configure Watchmouse you probably want to have a quick alert by e-mail or SMS/text message when things don't work and have additional diagnostic information available. In this way, downtime alerting paging can be kept to a minimum. It is not only the quality of the systems that counts, but also the speed with which you can fix problems.

Your role could also be in overseeing your service providers, whether they are internal or outsourced. In that case, you don't want to be interrupted by these messages, unless the situation becomes dramatic. Instead you would like to look at the weekly report, and see if your service providers are living up to their promises. On the Internet it is easy to get 99% uptime, and you should really be doing better than that. The services that regularly fail to make this grade need attention, to see if another approach to provisioning them works better.

If you are considering technical alternatives for the way you are setting up your e-business, you are most likely interested in typical failure modes. For example, we know from experience that most website problems are software problems, followed by sizing problems. Communications problems are fairly rare, and if they occur they take the form of peering problems: websites cannot be reached from specific networks, even if all networks are operational. One approach using Watchmouse reports is to check various aspects with different rules. Use one rule to download the homepage, another to check the DNS and a third to check connectivity to the hosting centre. In a next column I'll go into the details of this.

Online shops, speed and downtime alerting paging, getting the facts. (2009-12-07)

These days your website plays an important role in informing potential customers, converting them into customers who want to do business with you, and possibly also conducting the transactions with these customers. In other words: Your business relies ever more on the digital economy, and increasingly on the transactional part of it, the online shop.

These online shops should obviously provide satisfactory downtime alerting paging. Here, both the speed at which they serve pages and their uptime are important. If potential customers cannot reach the online shop, or the online shop is too slow, they are less likely to do business with you now, and in the future. Studies have revealed that half of the people who experience downtime alerting paging on a website go to its competitor. A majority of online shoppers say downtime alerting paging and uptime influences their choice of online shop.

The amount of revenue that is lost when your website or online shop does not behave properly is hard to quantify. If your website is slow your customers may select a distribution channel that is more costly for you, or they may go to your competitor. Even worse, they may complain about your company to other potential customers. All of this boils down to lost revenue.

A good website is up for at least 99.9% of the time, even though this still represents more than 8 hours in a full year. In a recent survey we found that many websites do not even achieve 99% availability, which corresponds to more than 3 days of downtime alerting paging a year. As regards speed, if a web page does not load in less than 4 seconds, people start to leave the site, sometimes forever.

How do you make your online shop an efficient experience for your customers? The site must be designed with a strong focus on the customer task. The technology must be no more complex than is relevant. People get annoyed by slow loading Flash intros and complex and slow Flash-based navigation. Take a look at the Google home page; it is one of the fastest websites in the world. On the other hand, you can still use a video clip of a product, if that is relevant to the customer at a particular point in the transaction. You can also use advanced Web 2.0 technology if it makes the user interface more resilient and user-friendly. To experience this, look at Google maps using a dial-up internet connection. It is a really complex user interface, but everything possible has been done to create a positive user experience.

Technology is also important; make sure that you have good service level agreements with all your technology providers. You also want to stress test the site, to see what happens if a lot of people start using it simultaneously. Finally, you should independently monitor the site. When it is time to talk to your hosting company, IT department or website maintainer, it is very helpful to have hard data that reports on the speed and uptime of your online shop.

Website downtime alerting paging is the key to customer satisfaction (2007-06-27)

How often have you typed in the Google URL and received a page that will not load? I am willing to bet that this is a rare occurrence. Despite its busy traffic, Google is a textbook example of a web site that has almost perfect downtime alerting paging and therefore serves a great number of satisfied customers. The market share of the search engine is a resounding confirmation of this. You are assisted quickly, so you come back sooner. Research conducted by JupiterResearch has revealed that visitors to a site only have 4 seconds of patience. If the site has not been loaded by that time, they leave. Error messages also prompt potential customers to go to the competition.

Why do organisations still devote so little attention to the effective availability of their site? Performance is the key to satisfied customers. For many companies, their web site is the face of the organisation. Consumers and also business users of the Internet use the wealth of information on the web to compare purchasing options. It is of immeasurable importance that they are also actually able to find what they are looking for. If this is not possible at one company, competitors are straining at the leash to offer their services through a correctly functioning site.

Coming back to the praise that we had for Google, we see that the search engine has made significant investments in the availability of its web site. The page is run by several machines at various sites. If one crashes there are enough back-up servers that can take over the traffic flows to guarantee optimum downtime alerting paging. In addition, the search machine invests a great deal of time and money in the right hardware and people. Although the site has a difficult task – searching through an index of billions of documents – it is almost always available and loads fast.

The actual site is unspectacular in construction. This applies to the majority of sites with a high level of availability. Simple sites such as the news site NU.nl are almost always easy to access. Nevertheless, it is not only the layout of the site that determines how the web page performs. Too many photos, long symbols and frills make web sites slower to respond. The fact that the ‘back end’ of the site is not efficiently programmed also contributes to longer loading times. Frequent consultation of background databases is also detrimental to the speed of the page.

Where it often goes wrong is when different people are working on a site, thereby disturbing the links between the various elements. The different parts of the site will work correctly, but the site as a whole will fail to perform. This means long waiting times for people who want to use the services of a company.

Service providers at the upper end of the market are becoming increasingly aware of this. The contracts that they use frequently include a service level agreement (SLA) for the part for which they are responsible. Nevertheless, they regularly make mistakes due to the fact that the promised downtime alerting paging is not subsequently verified (by an independent party). Although it is now essentially part of the contract, there is insufficient actual verification. Ideally, web site downtime alerting paging should become a permanent component of a contract. In addition, clear internal agreements must be made on who has final responsibility for the efficient loading and availability of a site.

Regular testing is also essential for the facilitation of good availability. This will prevent a great deal of errors, keeping the site up and running at crucial times. The storm that blew over the Netherlands at the end of January was a good opportunity to see which sites were prepared for extreme loads and which were not. The site of the Dutch weather institute, KNMI, was almost unreachable, while some logical thought could have protected them from this eventuality. If you know that a major storm is heading towards the country you can be sure that people will search for information on the weather and roads on the Internet. Sites such as those of KLM and Schiphol were also unreachable, while the specially created site Crisis.nl, which had been kept as simple as possible, was able to serve a large number of people.

Including ‘stress tests’ in a SLA or conducting them regularly in-house is therefore to be recommended. Companies can easily take control by ensuring that their service provider executes this type of test or by putting their own site under pressure. This is the best method of checking whether your web site can handle a sudden increase in visitor numbers. It is also good to know whether the servers on which your site is running actually ensure that your page is always available and loads correctly. For companies, it is crucial to see when they are off air. This can save them a large amount of money every year and will also reduce the number of irritated visitors to the site. This is how you keep customers satisfied and keep the company running.

Linux-based websites 'perform better' (2010-01-13)

Linux-based websites perform better than those hosted on Windows servers, according to research.

WatchMouse, a Dutch firm that monitors server performance, based its research on a survey of over 1,500 European websites. The company says that, although the websites it surveyed were more frequently based on Microsoft's IIS web server platform running Windows than on Apache running Linux, the latter option performed better in terms of both downtime alerting paging and load time.
