Internet Site Monitoring

Launching WatchMouse Laboratories: the tech playground for website monitoring (2009-10-08)

We just launched WatchMouse Laboratories (labs.watchmouse.com)

This blog is the experimental outlet of the WatchMouse engineering team. Here we will share our thoughts on website monitoring, publish experimental features, hand out beta-invites and ask for your opinion.

Our first post is "Investigating IPv6 Website Monitoring", explaining about our work to be ready for the IPv6 Internet. As you might know IP addresses are running out, and many efforts are being made to replace the current Internet Protocol (IPv4) with version 6, which allows for an almost unlimited number of IP addresses.

Of course this will also have consequences on Website Monitoring of IPv6 enabled web sites and servers. WatchMouse is currently working to make this part of their standard offering, and some of our thoughts and findings are shared on our new labs blog.

Read more about IPv6 Website Monitoring on our labs site, and feel free to leave a comment!

Monitor your transition to IPv6 with WatchMouse (2009-10-14)

You've heard it before, and it's being announced more frequently and louder: The number of available addresses on the Internet is running out, and we all should move to the new addressing scheme, IPv6, as soon as possible. The uptake has been rather slow in the past, but that seems to be changing now as companies, ISPs, and other organizations are taking their first steps on the road to the IPv6 world. For most of these companies, however, this is quite a big step, with many things to consider and many uncertainties.

External IPv6 monitoring

As of today, WatchMouse offers IPv6 monitoring for web sites and other external services of your company. The monitoring network will, just like visitors of your website that happen to be on an IPv6 connected network, connect to your site when an IPv6 record is available in the DNS of your domain.

Check your IPv6 connectivity right now? Just visit our Check Host tool or the Ping tool. And while you're at it, set up a rule in your account to monitor your site continuously from our world wide monitoring network.

Many changes

To fully enable IPv6 monitoring, we have upgraded several components of our infrastructure:

• Our worldwide monitoring infrastructure, including the monitoring software
• The backend systems, including our databases and the WatchMouse API (see a post on this on WatchMouse Labs).
• The configuration portal (settings), where you can now specify whether or not to monitor over IPv6, if possible.
• The free tools on our site: check host and ping.

By offering IPv6 standard in all packages (including the free package and the 30-day trial) and in the tools on our site, we hope to facilitate a smoother transition to IPv6 in your organization.

Is your company interested in IPv6? Then do keep an eye on our IPv6 posts on WatchMouse labs.

WatchMouse releases new Site Performance Monitoring Widget for Apple users (download widget) (2006-10-22)

WatchMouse releases 2.0 widget for dashboard, aimed at Internet site performance monitoring.

NETHERLANDS, 2006-10-23. By means of the widget Apple users can get direct insight into the performance of their own Internet site. The widget can be downloaded for free from the Apple website.

In 2002, WatchMouse (www.watchmouse.com) introduced a new concept for Internet site monitoring. By means of ongoing simulation of Internet visitors the performance of sites and servers is verified. If a site is not responding, an alert message is sent immediately through SMS, pager, Instant Messenger or e-mail. The sites are checked from over twenty 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 twenty 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 alerts 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 over 20 different locations worldwide.

Worldwide monitoring

The new version (2.0.4) brings continuous performance monitoring, even when the Mac is not connected to the Internet, by connecting the widget to a WatchMouse account (free or paid). In October 2005, WatchMouse released the first version of this widget, which was downloaded over 10.000 times.

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 creative director Niels Eijsbroek. "We give the widget away for free mainly for the fun part. And of course it's also important to bring site performance monitoring to the attention of our fellow Apple-users."

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

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 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 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 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.

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 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.

Linksys WVC54GCA Wireless-G Multiple Cross Site Scripting Vulnerabilities (2009-04-28)

Linksys WVC54GCA Wireless-G Internet Home Monitoring Camera is prone to multiple cross-site scripting vulnerabilities because the software fails to sufficiently sanitize user-supplied data.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

Linksys WVC54GCA Wireless-G Internet Home Monitoring Camera firmware 1.00R22 and 1.00R24 are affected; other versions may also be vulnerable.
