Health monitor issue
Hi all,
we have a rather pressing and odd issue. Like most users I have setup health monitors to monitor the individual nodes within a pool. These health monitors used to work. Now at some unknown point this stopped. The reason why it is at some unknown point is that the health monitors are indicating nodes as being up when they are not. At the moment I am having to force the node down on the nodes that are down for maintenance. I am totally confused and alarmed at this behaviour. The health monitors in question are very basic monitors, they simply check for what is returned from a
get /wps/portal
and checks for the string
WebSphere Application Server
This used to work. I am totally at a loss as to why it's suddently stopped working. I can ping the physical servers from the BigIP units. Is there any command line tool on the BigIP to test monitors or any monitor debuging tool?
Sorry, forgot to mention, our units are running BIG-IP 9.4.7 Build 320.1 Final
We are in the planning to go to 10.x next week.
Regards
Craig
