Web Link Monitor Funnies

Greetings All

We have picked up a funny with WEB Link monitors that is causing quite a bit of confusion. We host a fair number of WEB sites on a production WEB server in a DMZ and we use WEB Link monitors to the root of each of these sites (www.SiteName.com - no deeper URL's) to monitor te response and availability of the sites. It works perfectly well, except that our developers are picking up an enormous number of WebEvent Errors from their built-in error monitors. The erros are all similar in that they complain about malformed URLS referring to either illegal characters in the path, or object references not set. Looking at the details of the errors, it seems as though the SolarWinds monitoring servers is trying to access "rubbish" or random URLS. They all look something like this:

http://www.site.co.za/ContentName.aspx?Name=Technology&Scheme=92&Version=2

where the web link monitor only contains www.site.co.za

'Web Link' monitor is used to verify all hyperlinks from that page. So it seems that there are really some links to those "random" URLs.

'HTTP Monitor' is used to verify that web server responds and send some page back for specified URL (it doesn't follow hyperlinks on that page) so maybe it would be more appropriate for what you need.

Are your HTTP Monitors set to 'Follow Redirect'? If so, could you try to disable it to see if behavior changes?

Not using HTTP monitor. We are using the WEB Link monitor (as distributed with SW). Should we rather use the HTTP Monitor?

Thanx guys! I clearly used the wrong monitor. Sorted now!

Response time returned by the web link monitor is the HTTP response time of the URL provided for the monitor or sum of the all the response times of the hyperlinks from that page.

If there is an link for img or swf , will the web link monitor tries to download or just check whether its reachable ? and reports the response time ..
