Hi All,
First post on this blog. Just wondering if anyone knows how to create a Custom Monitoring condition for a test in the following scenario:
I have 2 servers which are Active-Standby configuration, both servers are configured the same way, currently I've monitor created to fetch info from each server with HTTP Test method by a GET Request and Checking specific Contents.
The Active server has 50 extensions registered and when tests are performed, all looks fine as the extensions are online, however on the Standby server, because it has no extensions registered, I get BAD Request status.
The servers could swap roles and then the previous Standby server will take over Active role and it will register 50 extensions to it, and to old Active one will un-register the extensions.
My goal is to create a Custom Condition test which allow me to check the Active server extensions status and for the Standby server, monitor it to check if Active server role and status are OK, and in case of failure of Active one, the Standby server becomes Active and start monitoring the extensions status for the new Active server.
Hope I express myself clearly enough!!!
Condition to perform dependant test
Not sure I understand.
How many tests have you set?
2 tests - one for each server?
Or 100 tests - 50 tests for each server?
Do you want to set 2 Master tests (one for each server) and 100 dependent tests (50 for each server)?
If you have just 2 tests, I assume you want to get some alerts when both tests returns "bad" status at the same time?
While "good"+"bad" test results should not trigger actions?

I have 2 tests, one for each server. The test consist on an search for HTTP text string on a web page to confirm status of the 50 extensions. The Active server shows the 50 extensions registered, the standby server not, reason why I get BAD request.
My intention is to have alerts on Active server showing up, and alerts on Standby server on hold until it gets Active because failure of the other server.
I was thinking about to have 2 lines HTTP string search, but not sure how to make it to work as the files on "Text Method \ Advanced \ Check Contents has only one field to add text, reason why I was thinking on adding Custom Monitor to detect which server is active and only alert for the tests on active server and stays on-hold for Standby server until it gets online.
Thanks in advance for your help

Sorry, still do not understand 
How exactly HTTP response looks in both cases?
What text should be detected for "good" test status?
What text should be detected for "bad" test status?
Something like:
"active" should be present and "failed" should not be detected for "good" status?
"standby" detected - set "good" status regardless of "failed" text presence?
"active"+"failed" - "bad" status?

Sure, I understand is hard to get it as this is a very custom test.
The HTTP text that I'm currently searching is:
- Recording devices registered with DMCC - 50
But I need to add another extra search for:
- Recorder Role: Primary
In case both expressions match, that is the Active Server, so it basically confirms Registered extensions and Server role
My idea is something like this:
If "Server Role: Primary" and "Recording devices registered with DMCC - 50" then Status is: Host is Alive
If "Server Role: Backup" then Server Status "waiting for Primary"
The test should be smart enough to identify which server is primary and which one is backup in order to run the test for only Active server.
Does it makes more sense now?

I think you don't need any master-dependant set of tests.
You may set 1 test (per server) with the following option
Check content: use expression "Server Role: Backup" or "Recording devices registered with DMCC - 50"
Test will set Bad status when (serverrole<>backup) and (DMCC<>50)
Otherwise HostMonitor will set Ok status.
Unless both servers may switch to "backup" mode and this should be detected as "bad" condition?

That is correct, at the moment both tests are created searching for -Recording devices registered with DMCC - 50 - but the part of the Custom expression to make the test search for other conditions is the one I can't complete.
You are suggesting something like this: Test will set Bad status when (serverrole<>backup) and (DMCC<>50) which I believe is fine and I could start from there, however could you please show me some examples, or at least the structure that should contain the Custom Expression?
Thanks for your help.
