URL/Http Monitoring

Hi There,

Below is what I intend to achieve....can you let me whether this can be done.

Please execute one HTTP check that hits the URL http://xx.xxxx.xxxxservlet/StatusServlet (give it a timeout of 30 seconds, with a 2nd knock if possible just to be sure). This check should can occur every 15 minutes.

If the above ping check succeeds, but If this URL is unreachable send an email to XXX@xxx.com which notifies me

- If the url is reachable either of the following 2 strings of text in the response indicates things are OK and no notification is necessary
<overall_status>ok
<overall_status>warn

- If the url is reachable, the following string indicates a failure condition that I need to be notified about
<overall_status>fail

We are using Orion Network Performance Monitor 9.1 SP5. I want to do this check without assigning a node......however this is the only way it seems to be done through HTTP Monitor template.

Yes, you can do this with SolarWinds Orion APM.

However, you say you don't want to an assign an Orion APM HTTP monitor to the webserver node. But, that is how Orion APM works.

You can also use the HTML/ASP monitors in SolarWinds ipMonitor for this.

Hi Roger,

Thanks for your reply. I have tried to use the HTTP Monitor template...however when I put the search string that needs to be checked...no matter even if I define a wrong string....the test is always successful. Also, I have seen a feature in orion 9.5 were we can add an external node (url's as well)...without actually having to monitor that device from within Solarwinds. Is that correct?

Thanks.

Hello Shailesh,
monitor test should fail if you specify search string that is not on the page. Are you sure that string you entered is really not present on the page anywhere?

Regarding external nodes, these are nodes that are not monitored by NPM and serve just for assigning items such as application templates. If you need to monitor URL, you can add your node as external and assign HTTP monitor to it. Then it will be monitored only by this HTTP monitor and not by any other means.

Hmm. I use that HTTP monitor component to send me SMS messages when certain concert tickets go on sale. When they go on sale, the monitor fails and my alert sends me an SMS message. My HTTP monitor settings look like this:

Search string: ON SALE NOW!

Fail if Found: True

So, your setting should look like:

Search string: <overall_status>fail

Fail if Found: True

If that's what you have and it does not fail when retrieving your failure page, please open a support ticket. This should work the way you are expecting it to. As an additional test, you might try it with only fail as the search string.

Yes, you can add servers as external nodes. Orion NPM still monitors whether the node is up through ICMP, but no statistics are stored for it. I use this to assign APM applications to www.google.com, updates.microsoft.com, and any other servers that do not belong to me.
