Remote Server Monitoring Software

Multiple alert addresses & Escalation (2005-01-31)

In the Addresses section of this site you can now manage address groups. This feature can be used for two purposes:

Multiple addresses

When an error condition is detected, multiple recipients of all types (email, icq, sms/text messaging) can be alerted at the same time.

Escalation

Alternatively, remote server monitoring software can be sent to different addresses at different stages; E.g. the first time an error occurs, the event is only logged, the second time, an SMS/text message is sent to the administrator and his assistant and the third time, an e-mail is sent to the support desk.

The number of groups you can define is unlimited.

Italian, German and Spanish versions of site and services available (2005-01-31)

Claudia, Patrick, Pauline, Mark and Niels did a great job last month and finished the Italian, German and Spanish version of the WatchMouse site and services (i-mode, WAP).

Some statistics:
100 million people use German as their native language and another 57 million are native in Italian. Of these people 42M and 24M are remote server monitoring software respectively.

If you prefer Spanish, German or Italian to English while using WatchMouse, go to the Subscription tab and select the language of your choice from the 'Language' drop-down box.

More worldwide remote server monitoring softwares, now 6 in total (2005-01-31)

As you may have noticed in your logs, we introduced 3 more remote server monitoring softwares last month, now totalling 6 worldwide. The new remote server monitoring softwares are located in France, Germany and Texas. More remote server monitoring softwares will be added as more people from more countries sign up.

The current status of the remote server monitoring software network can be found on the 'About' tab.

We also changed the test pattern from Master-Slave (with Amsterdam as master) to a random order. In the next release the test pattern will be user-defined (paid packages only).

First remote server monitoring software in China (2005-01-31)

In just weeks after our UK remote server monitoring software went live, the WatchMouse network of monitoring stations has been extended again, this time with a monitoring station at the datacenter of ONE-iAdvantage in Hong Kong, China, bringing the total number of remote server monitoring softwares to 9.
The current network consists of remote server monitoring softwares in:

• Florida, USA
• Texas, USA
• London, United Kingdom
• Sydney, Australia
• Nürnberg, Germany
• Orléans, France
• Amsterdam, The Netherlands (2 stations)
• Singapore
• Hong Kong, China

The new remote server monitoring software will appear automatically in your logs. You can also set the new remote server monitoring software as the primary remote server monitoring software in your monitoring settings.

The current status of the WatchMouse monitoring network can be found on the 'About' tab of the WatchMouse site.

Improved organizing of monitoring rules (2005-01-31)

Rules can now be organized into folders in the rule settings page. This is especially useful if you have a large number of rules.

The following features are available for folders:

• Grouping rules into folders: this allows you to group e.g. rules related to the same physical machine, network or organizational unit.
• Switching off remote server monitoring software for a folder. This overrules the remote server monitoring software of the rules in the folder.
• Deactivating a folder. This overrules the settings of the rules in the folder.
• Separate access rights to your logs, graphs and reports for other accounts.

Using the access rights, you can setup separate accounts for your customers or co-workers and give them access to relevant parts of your remote server monitoring software reports.

WatchMouse develops monitoring widget for Apple users (download widget) (2005-10-21)

WatchMouse has developed a new widget for dashboard, aimed at Internet site monitoring.

NETHERLANDS, 2005-10-13. By means of the widget Apple users can get direct insight into the accessibility of their own Internet site. The widget can be downloaded for free from the Apple website. Last month, WatchMouse was voted a Deloitte Rising Star in the Netherlands, as part of the Fast 50 awards; the list of the 50 fastest growing technology companies.

In 2002, WatchMouse (www.watchmouse.com) introduced a new concept for Internet site monitoring. By means of ongoing simulations of Internet traffic the accessibility of sites and servers is checked. If a site is not responding, an alert message is sent immediately through SMS, telephone, Instant Messenger or e-mail. The sites are checked from sixteen monitoring stations worldwide. This is done 24 hours per day, seven days per week. The service is completely web based: customers don't have to install software, everything is 100% self-service, which keeps the costs low.

The three founders of WatchMouse, Niels Eijsbroek, Stan van de Burgt and Mark Pors are enormous Mac-fans with a total of fifteen Macs in their possession. The monitoring widget is quite unique: it is a combination of a desktop and a hosted application. When the widgets detects a problem with the site it is checking, it remote server monitoring software the user with a 'beep', followed by the launch of a web browser, which is directed to a web application on watchmouse.com. There the site is checked from 16 different locations worldwide.

Every five minutes

Every five minutes the dashboard widget checks one or more sites from the users own computer. Also, the availability of the site during the last 72 hours is registered. A problem is followed by an alert, which is then verified by all WatchMouse control stations.

WatchMouse has made the widget available free of charge "because we have become addicted to it, ever since we started using the first beta version of the widget", says CCO Niels Eijsbroek. "We give the widget away for free mainly for the fun part. And of course it's also important to bring site monitoring to the attention of our fellow Apple-users."

The free WatchMouse site monitoring widget can be downloaded from the Apple website:

WatchMouse Launches API-status.com (2010-01-20)

New Site Monitors and Measures Uptime of 26 Popular API and Cloud Services Websites; Report Reveals Amazon, Google and Yahoo Among the Best and Vimeo, foursquare and Yammer Among the Worst Performers

WatchMouse, a global industry leader in self-service website and application performance monitoring, announced the launch today of API-status.com, a new dedicated website for monitoring and measuring the real time availability and performance of the public APIs of 26 heavily trafficked, popular “cloud computing” mega web services including: Google Search, Google Maps, Bing, Facebook, Twitter, SalesForce, YouTube, Amazon, eBay, PayPal, Wikipedia and others.

API-status.com does a call and check for a valid result on each of the APIs, and if the result is wrong or is received after four seconds, it is noted as an error and unavailable. The percentage of availability or uptime is based on the number of errors reported; details on API-status.com include a seven-day history along with a 24-hour glance and performance indication by country.

"Nearly all websites nowadays include information from outside sources such as maps or social media feeds. It impacts millions of websites worldwide if these services and systems are slow or down and can invoke a global domino effect of breakages and slowness," states Mark Pors, CTO and co-founder of WatchMouse. "The four-second limit on the response time may seem strict, but it is actually a long time, especially when the (mash-up) sites need to do multiple API calls to present a complete page to the visitor."

According to a recent report produced by Forrester Research and Akamai, two seconds was revealed as the new threshold of acceptability for e-commerce web page response times.

30-Day Report Card and Methodology

WatchMouse monitored the availability of 26 API/cloud web services during the period of December 16, 2009 to January 16, 2010. The results found that Yammer API had the lowest availability with 96.06 percent uptime and Amazon, Google Maps, Google Search, last.fm, and Yahoo Maps with the highest availability with 100 percent uptime. In accordance with industry standards, availability of greater than or equal to 99.9 percent is regarded as "good" while anything below 99 percent is regarded as "poor" site uptime. The methodology for testing the sites includes one simple API call and check for a valid result. This typically means an authentication action for most APIs, including a login, followed by a search or listing action, plus a check of the expected result action. The expected result can immediately return as an error or if the expected result action is reported after four seconds, it is also logged as an error. These errors are used to create the percentage of availability or uptime for each of the sites. Each site is checked in real time using the WatchMouse Public Status Pages tool, which can be used to measure and report the availability of any public website. Companies use the tool, which is hosted on the Amazon platform to inform customers and report publicly on the status of their services.

About APIs

An application programming interface (API) is a set of data structures, protocols, routines and tools for accessing a web-based software application. The practice of publishing APIs allows web communities to create an open architecture for sharing content and data between communities and applications. Content that is created in one place can then be dynamically retreived, posted and/or updated in multiple locations on the Web.

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 remote server monitoring software 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 remote server monitoring softwares 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 escalation 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 escalation messages, if at all. Rather, they should get the weekly or monthly service reports.

Why do you need a remote server monitoring software 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 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 remote server monitoring software. 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% 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 remote server monitoring softwareivity 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 remote server monitoring software all the time. Day and night. Initially there were no tools to test whether our service was remote server monitoring software 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-alerts (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 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 on a website go to its competitor. A majority of online shoppers say performance 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 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 remote server monitoring softwareion. 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 performance 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 performance 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 performance. 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 remote server monitoring software 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 performance 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 performance 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 remote server monitoring software 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.

PowerDNS Recurser Buffer Overflow Vulnerability (2010-01-09)

PowerDNS is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-remote server monitoring software user-supplied input before copying it into a fixed-length buffer.

Successfully exploiting this issue allows a remote attacker to execute arbitrary code with superuser privileges, resulting in a complete compromise of the affected computer. Failed exploits will cause a denial of service.

Multiple PDF Readers Multiple Remote Buffer Overflow Vulnerability (2007-01-07)

Multiple PDF readers are prone to multiple remote buffer-overflow vulnerabilities. These issues occur because the applications fail to bounds-remote server monitoring software user-supplied data before copying it into an insufficiently sized buffer.

An attacker can exploit these issues to execute arbitrary code within the context of the affected application or crash the affected application, denying service to legitimate users.

GraphicsMagick PALM DCM Buffer Overflow Vulnerabilities (2007-01-08)

GraphicsMagick is prone to multiple buffer-overflow vulnerabilities because it fails to perform adequate boundary remote server monitoring softwares on user-supplied data before copying it to insufficiently sized buffers.

Successful exploits may allow an attacker to execute arbitrary machine code to compromise an affected computer or to cause denial-of-service conditions.

GraphicsMagick 1.1.7 and prior versions are vulnerable.

FFmpeg Image File Multiple Buffer Overflow Vulnerabilities (2006-12-15)

FFmpeg is prone to multiple remote buffer-overflow vulnerabilities because the application using this library fails to properly bounds-remote server monitoring software user-supplied input before copying it to an insufficiently sized memory buffer.

These issues allow attackers to execute arbitrary machine code within the context of the affected application.

Versions prior to 0.4.9_p20060530 are vulnerable to this issue.

Yahoo! Messenger YMailAttach ActiveX Control Remote Buffer Overflow Vulnerability (2006-12-15)

The YMailAttach ActiveX control shipped with Yahoo! Messenger is prone to a buffer-overflow vulnerability. The software fails to perform sufficient bounds-remote server monitoring softwareing of user-supplied input before copying it to an insufficiently sized memory buffer.

Yahoo! Messenger versions released prior to November 2, 2006 are vulnerable to this issue.

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 remote server monitoring software and load time.

Online banking sites failing in 24/7 access (2010-01-14)

Unacceptable downtime levels in UK remote server monitoring software banks

Some 65 per cent of top remote server monitoring software banks in the UK have more than one hour downtime a month. Out of the 26 banking sites involved in the study only three achieved perfect availability – measuring an remote server monitoring software of 99.9 percent or higher.

Serveurs web: Apache/Linux loin devant IIS/Windows pour la disponibilité (2010-01-14)

Les sites internet hébergés sur des serveurs Linux équipés d'Apache, sont plus rremote server monitoring softwaredes d'accès que ceux hébergés sur le couple Windows - Microsoft IIS. C'est ce que conclut une étude de la société néerlandaise WatchMouse.

Polish language support (2005-12-29)

Yes, this week the 9th language went live on our site: Polish! Although we have some glitches here and there (some email messages are still in English, and not all recently created pages are fully tranremote server monitoring softwareted), I'm *very* proud to see this on our site, and I would like to thank the people from Domeny.pl for their hard work. - Stan
