How do you monitor your LTMs/GTMs

I expect you'll get many different suggestions/opinions on this. Here are some quick thoughts:

 

 

Many customers I work with use external monitoring tools or services that make requests to the LTM VIPs or GTM WIPs. Ideally they're checking dynamically generated content that touches the database to track client experiences. This is one important view of the entire health of the application stack including the F5's.

 

 

You can also monitor CPU/memory usage via SNMP or CLI tools. For spot checks from the CLI standard Linux tools help, along with tmstat.

I've spoken to several sources who all say SNMP should be the standard. Taking that a bit further, what OIDs are people querying to determine the overall health of the system? I'm not interested in the OIDs relating to TMM - I have other ways of validating that our application traffic is being processed. I'm more concerned about the system health.

I suppose what you would want to check is the following

 

 

CPU

 

MEMORY

 

DISKSPACE

 

Processess

 

bigd

 

mcp

 

named etc

 

 

These are the elements to check for the overall health of the BIGIP.

 

 

You will not find SNMP OID for process - at least I couldn't find it so hopefully your monitor can do more then simply SNMP checking.

 

 

I hope that helps
