Website Check

[jkinning]

I have a website that uses an F5 for load balancing between two servers. I am monitoring these two servers, ServerA and ServerB, for basic hardware checks (cpu, memory, disk space, etc). The website is called mysite.com and on each server I have an asp page that has a value. This page ensures the site is up and communicating with the backend database correctly. The text on the asp page is ALL IS GOOD. I want to place a check for the website and list the website check in a different Host Group. The ServerA and ServerB are in a WIndows Prod Host Group and I want mysite.com to be listed in the IIS Website Host Group.

My question is can I create one service check and add this service check to each of the servers while also making each server a Parent, so when Server maintenance happens we can disable notification for Windows Prod Hostgroup and no notifications will be sent out? Or will I need to create two separate service checks? The service check will basically be to check the webpage using ssl to look for ALL IS GOOD when hitting the ServerA/myasp.asp page and ServerB/myasp.asp page.

I am thinking I am over complicating this but at a loss and looking for some guidance to simplify this web check without creating more work and unnecessary service checks.

I'm trying my best to follow the logic - I think I mostly have it.

You cannot have circular dependencies - that's the rule. The other thing is a host can't be the parent of a service, so hopefully you were hoping to have three hosts.

With that said, this is valid:

Code: Select all

define host{
     host_name     mysite.com
     parents     IISa, IISb
     }

define host{
     host_name     IISa
     }

define host{
     host_name     IISb
     }

The way the logic works is that even if IISa goes down mysite.com is NOT unreachable. Does that answer your question?

Thanks that helps.

OK to lock and mark solved, or do you think we'll need a revisit?

You can lock.
