New: A complete overview of the last 24 hours (2006-10-03)

Would you like to see on the monitor at a glance how your website has performed in the last 24 hours? This is possible with WatchMouse's Performance Chart.

In addition to reports by e-mail and information in the log files, WatchMouse has now introduced the Performance Chart. This makes for even easier and clearer depiction of the check server downtime of your websites. The Performance Chart gives a complete overview of the last 24 hours, per rule and with an automatic update. You can therefore see at a glance, in colour, exactly when the website has been slow, unavailable or error-free. The size of the problems is shown in percentage terms. The Performance Chart can be found under the Reports tab. URL: http://www.watchmouse.com/check server downtime_chart.php

WatchMouse also offers even more information in the Dashboard. On this status page, you can indicate precisely what graphics and log files you wish to see. Some time ago, the Current Status page underwent a complete make-over. Resulting in this Dashboard. The graphs are renewed independently from one another. You yourself can set an interval, between 1 and 60 minutes. You can select the elements you want and move these to another location on the page. In addition to your own log files, you can show logs and graphics from other accounts to which you have access. The layout and settings are saved in your own account.

In order to put together your own status page, go to the url below and click on ‘add’ at top right to enter the first graph. URL: http://www.watchmouse.com/status.php

New: scheduled maintenance, work schedules, check server downtime indicators (2006-11-28)

1. Set-up maintenance periods per rule

   In the monitoring settings page, in "expert mode", you can now:

   • Start and duration of the maintenance period
   • Optionally set the repeat period (daily, weekly, monthly)

   During the maintenance period, WatchMouse will continue monitoring your servers but errors are not included in downtime calculation, and alerts are not sent. In the check server downtime chart and logs, the checks while in maintenance are marked as such (see legend). The maintenance periods will be made visible in the graphs too.

2. User defined check server downtime limits

   You can now define on a per-rule basis the limits for good, poor, and bad check server downtime next to the existing ('timeout'). These limits can be entered in the monitoring settings page, in "expert mode". These limits are used in the check server downtime chart.

3. Work schedule options in your contacts

   You can now specify which days, and which hours people in you contact list are on duty:

   • When not on duty, no alerts will be sent to this contact person
   • This is also useful for group alerts, with non-overlapping schedules
   • A contact can now also be set to 'inactive' manually, just like the monitoring rules
   • Inactive contacts do are not included when computing the maximum number of contacts you can still use

   You can set the work schedule in your contacts page, after selecting one of your existing contacts or entering a new contact.

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 check server downtime server downtime 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 check server downtimeed for accessibility, speed and conformance from different locations around the world. Because the websites are check server downtimeed 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 check server downtime server downtime. 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"

Dutch e-commerce sites poorly prepared for Christmas rush (2004-12-14)

Only 20% achieve maximum check server downtime server downtime

UTRECHT, 20041205 -- Many Dutch e-commerce sites have made only minimal preparations for the increased number of visitors in December. The congestion caused by Sinterklaas [traditional Dutch celebration on 5 December] meant that, on average, only one in six sites was continuously check server downtime server downtime. This was the conclusion of WatchMouse, a Dutch monitoring site, following a survey of 25 e-commerce sites. Even worse figures are expected during the weeks before Christmas. 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 25 sites where consumers can shop online, such as Bol.com, Wehkamp, Free Record Shop, De Bijenkorf, ECI, Bart Smit, Dixons and Bruna. The survey shows that the 'up time' – the time during which the server is online – varied from 98% to 99.6%. "This may seem high, but a score of 98% means that a site is not check server downtime server downtime 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.

The consequences of this are reflected not only in loss of income. Pors: "A website that is not check server downtime server downtime can cause stacks of work for a helpdesk and, at the end of the day, damage the brand’s image. The problem is that many website owners are unaware that sites are responding poorly, or not 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 only 20% of the sites have achieved optimum accessibility. Given the increasing trend in online purchases, gigantic sums are involved. In the first six months of 2004, online expenditure rose to € 775 million; a 35% increase. Each online shopper spent € 227 from January through June of this year (Blauw Research, September 2004).

December is also a top month for purchasing on the internet. Pors: "We saw response times and the number of error reports increase dramatically in the days leading up to Sinterklaas. This does not bode well for the even busier period before 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 users in more than 70 countries.

WatchMouse opens new monitoring stations in China and London (2005-01-12)

Largest monitoring network world-wide.

UTRECHT, 20041210 -- WatchMouse, active in monitoring websites world-wide, has opened two new monitoring stations: in Hong Kong and London. At the same time, the company’s station in Sydney, Australia, has been completely renewed. With this expansion, WatchMouse is responding to the explosive growth in interest in real-time site monitoring from e-commerce companies. With nine stations, the Utrecht-based company is now the largest monitoring network world-wide.

Thanks to rapidly increasing online expenditure via the Internet, services such as WatchMouse are undergoing significant development. A monitoring station provides insight into the check server downtime server downtime of e-commerce sites, the speed of these sites and response times. Research performed among Dutch websites by WatchMouse has demonstrated that many sites are still missing out in this area. Mark Pors, one of the founders of WatchMouse: “As spending online is growing by tens of percentage points each year, it is in the interest of sites to obtain insight into how they are functioning. A server that is poorly accessible for half an hour or more a day loses lots of money. Companies are increasingly recognising that they are losing out, both in terms of turnover and image. Not only in the Netherlands, but also elsewhere. For this reason, we are setting up stations in more countries.”

Local testing

By creating a larger spread among the control stations, sites can be monitored from more points throughout the world. WatchMouse is responding to increasing demand from clients for a world-wide picture of site check server downtime server downtime. WatchMouse’s clients can also stipulate a preferred station for 'local' testing. For this reason, China and Great Britain have been added as two strategically important markets for e-commerce. The Utrecht company’s other stations operate from Florida, Texas, Sydney, Nuremberg, Orleans, Amsterdam and Singapore.

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 check server downtime server downtime. 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 check server downtime server downtime varied from 98% to 99.6%. "This may seem high, but a score of 98% means that a site is not check server downtime server downtime 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 are reflected not only in loss of income. Pors: "A website that is not check server downtime server downtime 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."

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 check server downtime server downtime

Of the websites of the 25 funds listed on the Amsterdam stock exchange (AEX), only nine display optimal check server downtime server downtime. The check server downtime server downtime 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 check server downtime server downtime is that of Wolters-Kluwer, with an uptime of 94.80%, which represents more than 37 hours of poor performance, or even uncheck server downtime server downtime, 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 check server downtime server downtime 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 check server downtime server downtime. "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%."

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 performance and check server downtime 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 check server downtime by e-mail or SMS/text message when things don't work and have additional diagnostic information available. In this way, downtime 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% check server downtime, 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.

Independant, external testing (2005-10-15)

I started to work at Q-go in 2000. Q-go provides companies with self service pages on the Internet. Their customers ask a question in their own language and wording, and immediately get a very relevant answer. The power of the Q-go solution is its natural language technology, which enables it to understand the questions. The Q-go solution is offered as a hosted (ASP) solution, which of course has to work 24 x 7, a new area for me at that time.

At my previous jobs, at universities and research institutes, this was different. We worked from eight to six. If a demo application didn't work, the users just called, and we fixed the problem. And at six, we stopped and went home. All customers and other relations went home too. A nightly malfunction in the server was no problem, as there was no customer there to notice the problem.

At Q-go, this is completely different. A service should be available all the time. Day and night. Initially there were no tools to test whether our service was available or not. The only way to test it was to use the application itself. And so I did. During the day, but also at night, I checked whether the application was up. Our customers use the Q-go application continuously, and notice immediately when the application fails. Customers would call me in those cases, and it's not very pleasant to hear from your customers about an issue with your service.

So we developed some solutions ourselves to hear before our customers when something was wrong. And to be able to react to problems quickly. But customers kept calling!

How was that possible? Closer investigations revealed that the test system used the same resources (computers, networks, name servers) as the system under test... The test were not performed properly in case of problems. The text-check server downtimes (SMS) did not reach us either. The cause was identical: we used the same hardware, the same network, and the same power (!) as the systems we tested.

My lessons learned:

• Keep the systems that test completely separated from the systems you test.
• Test your services (web servers, mail servers, ...) from the point-of-view of its users: the customer on the Internet.
• Don't forget regular maintenance of your test systems (software and hardware) after the installation!

For me, I'm outsourcing external testing!

Online shops, speed and downtime, 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 performance. Here, both the speed at which they serve pages and their check server downtime 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 on a website go to its competitor. A majority of online shoppers say performance and check server downtime 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 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 check server downtime of your online shop.
