Monitor Site Web

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.

New Service: Monitoring the epicenter (DNS) of your online brands (2008-01-24)

Your domain name directs customers to a website where you represent your brand and all that it stands for but are you managing and regularly monitoring the domain name service (DNS) which translates your domain name and brings your customers to you? DNS consistency monitoring can help ensure your business does not lose customers to a slow or faulty DNS.

It is useless to have paid for an expensive and fully redundant web site server (park), if the DNS servers fail to respond, respond incorrectly, or inconsistently. Your DNS must be consistent and correct. Monitoring for DNS consistency is particularly important if you have online services relying on one or more domain names (and that is almost always the case). It doesn't matter if your DNS servers are maintained in-house or outsourced, you need to know if they are doing what they are supposed to do. WatchMouse's DNS consistency monitoring (now available in closed beta) checks your DNS systems and provides rapid notification of any unexpected DNS behaviour.

The WatchMouse's 'domain' type rule allows you to monitor the consistency of the behaviour of your DNS servers. It queries for a specified domain, performs a number of checks to test the health of your DNS servers and monitors for any difference in behaviour of your name servers. (If you also need to check that a domain name resolves to the correct IP address(es), you can use the 'dns' type rule which will be offered as part of the WatchMouse DNS consistency monitoring).

This new service will be available to all WatchMouse customers with a performance monitoring subscription (Webmaster and higher) and can be configured on the Monitoring Settings page. To set-up DNS consistency monitoring, simply enter the domain name (advanced settings are available).

Fancy participating in our closed beta test?

• Contact us to request participation in the beta.
• Collect all the domain names that are important to your business.
• Go to the Monitoring Settings page.
• Add a 'new rule' and select 'domain' from the type menu, for each of the domains you wish to monitor.
• Specify the other settings you would like for other rule types, hit 'save', and you're done!
• The results of the domain name monitoring appear in your logs, reports, and graphs instantly.

"Want to know the performance of your website?" (2006-11-29)

- WatchMouse launches Site Monitor for PC users –

Netherlands, November 29, 2006 - WatchMouse launches its free WatchMouse Site Monitor for Windows. This application provides PC users insight into the availability of their website(s) at all times. The Site Monitor can be downloaded for free at the WatchMouse website. Installing it only takes a minute.

The Site Monitor checks your company's site or your personal website at fixed intervals (5, 15, 30 or 60 minutes) from your own pc. When an error is found, or after 2 to 5 consecutive errors, you are alerted and the error is verified by all WatchMouse monitoring stations. Also, the availability of the site in the last 72 hours is shown in a performance chart.

The Site Monitor can be combined with a free WatchMouse account. This gives you the following extra benefits:

• The application can show you the monitoring results of all websites included in the account
• The monitoring is not only done from your own PC, but also from more than 20 WatchMouse checkpoints worldwide
• The application shows performance charts for any period in the Site Monitor
• In case of an alert the WatchMouse site is launched for more details
• Monitoring continues even when the PC is without an internet connection

In exchange for these extra benefits WatchMouse asks you to place a small uptime banner on the sites that are monitored.

The WatchMouse Site Monitor for Windows can be downloaded for free at http://www.watchmouse.com/windows/site_monitor.php Installing it only takes a minute.

WatchMouse expands Website Monitoring Infrastructure to 35 Global Monitoring Stations (2008-09-01)

In order to meet customer demand, WatchMouse is proud to announce the expansion of its global infrastructure with another eight monitoring stations being deployed over the past two months. The new stations are in: India, Israel, Japan, New Zealand, Russia, South Africa, Switzerland and the USA. WatchMouse now offers 25 monitoring stations in major European and North American cities, with a further 10 stations spread across Africa, the Middle East, South America and Oceania.

WatchMouse's extensive infrastructure provides the means to accurately monitor sites and web applications from the perspective of users based in different global locations. Such multi-point monitoring is imperative as site performance varies greatly depending on the location of the user (e.g. customers in the USA might quickly access a site, while for users in Germany, the same site has errors or a long load time). WatchMouse CTO, Mark Pors explains that "Even if your site works well from your headquarters, customers may still have trouble reaching it from different external locations. As a slow or faulty site can frustrate users, damage the reputation of a company and result in lost sales, it is essential to monitor from more than one point."

As the vast majority of businesses are aware of the need for global performance monitoring, WatchMouse was surprised to find global performance issues on the sites of some major international organizations, including the social networking site Facebook. In recent research WatchMouse found that facebook.com performs well in the USA but showed serious user issues from many other locations.

WatchMouse’s market leading infrastructure can help international organizations identify performance issues. Equally, WatchMouse supports clients who require performance monitoring within a particular region by allowing monitoring to be restricted to a sub-set of monitoring stations. This feature is useful for companies that only trade within a large country (e.g. USA) or region (e.g. Europe) but still require comprehensive monitoring within their area of operation.

About WatchMouse

WatchMouse provides global performance monitoring to thousands of customers in over 70 countries. In addition to a market leading infrastructure, WatchMouse offers automated alerting and an advanced user interface for complete self-management of all monitoring features and subscription details.

Spanish e-tailers not ready for Xmas shopping rush (2005-12-09)

WatchMouse research reveals weaknesses of Spanish online shops

Not a single Spanish webshop has an uptime of 100%, and only one out of 10 meets the regular industry availability standards. This is the conclusion of a research by WatchMouse, one of the fastest growing companies in the Netherlands, and winner of the Deloite Rising Star award in 2005.

WatchMouse has been monitoring the main ten Spanish webshops for 38 days, to find out if they are going to be able to handle the Christmas rush. The results of the WatchMouse Availability Index for Spanish e-tailers are poor. "We predict a long wait for internet customers this Christmas season, as Spanish e-shops don't seem to be ready to handle the increased traffic. In a fairly quiet period the performance has already been below standard. The extra volume of online shoppers before Christmas will definitely cause problems, and may even bring some sites down completely", says Mark Pors, CTO WatchMouse.

"According to recent research by the Asociación Española de Comercio Electrónico, retail e-trade in Spain reached some 1.8 billion euros in 2004. So there are big amounts at stake here. If customers cannot get through on a website, or are experiencing a long wait, they often decide to visit a competitive site, causing webshops to lose deals, and even risk losing loyal customers for good."

WatchMouse monitored the top ten Spanish e-tailers continuously from October 25 until December 2. Every 5 minutes, one of WatchMouse’s test stations tried to access the homepage of the site, which is expected to download within 8 seconds, without any errors. 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.

Of the ten websites monitored, there was only one meeting this requirement: Carrefour. Mercadona and AreaPC were the sites with the worst availability, showing a respective downtime of an equivalent of 10 and 16 hours over the 38-day testing period. In comparison: the main US e-tailers, such as eBay and Amazon all have 100% uptime, which shows perfect availability can be achieved.

A complete overview of the monitoring results of the 10 sites can be found on http://www.watchmouse.com/availabilityindex/2005/eshops-es.php
WatchMouse will continue to monitor the performance of the ten Spanish etailers over the Christmas period and will publish its findings in January 2006.

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.

W3C CSS :visited Pseudo-Class Information Disclosure Vulnerability (2007-03-01)

Cascading Style Sheets are a series of specifications produced and published by the World Wide Web Consortium (W3C). They are intended to provide a standard for adding literal formatting and layout information to HTML documents. CSS-1 is partially implemented by most web browsers, including Netscape and Internet Explorer.

Features defined in the CSS specification include the :visited pseudo class, used to define styles used on links to previously visited pages, and the ability to include external references in style declarations. Used in conjunction, these features may lead to an information disclosure vulnerability.

An attacker must construct a malicious web page, and include a link to a known, third party web page. The attacker may then define a :visited style for this link, and includes a reference to an attacker controlled file within the style declaration. When the malicious page is loaded, the user's web browser will access the external reference only if it is required. The attacker may then monitor the access to this file, and determine if the user has visited the specified page.

The :visited style defintion may also change information which is available through the browser DOM, allowing client side scripting to detect the state of the link. The script may then take intelligent action, possibly modifying page content or layout.

This is not a normal vulnerability so much as the consequence of a variety of design decisions, including usability and efficiency of the web browser and the difficult question of what information is safe to disclose in the DOM.
