iStats

Hi everyone, I'm trying to get my head around iStats, in particular how a key is constructed. Colin's article here is very confusing: https://devcentral.f5.com/tech-tips/articles/introduction-to-istats-part-1-overview. For instance, Measure Type is described twice with each definition being different;

 

"Measure Type - The statistics you want to gather about the subject, I.E. connections, requests, etc."

 

"Measure Type is counter, or "c" for shorthand"

 

So, which is it?

 

I've managed to derive this much;

 

 

· Keyspace – dotted tmsh command and module path to the object type you are gathering statistics on (for instance ltm.virtual or ltm.pool)

 

· Subject Name – the actual name of the object you want to gather statistics on including its Administrative Partition path (for instance /Common/vs_test or /Custom/test_pool)

 

· Subject Value/Measure – ???

 

· Measure Type – counter, gauge or string

 

· Measure Name – a user-defined name for the key

 

But this doesn't seem to match Colin's examples;

 

client 1.2.3.4 counter hits

 

src_ip 1.2.3.4 c Connections

 

In those two examples what would the keyspace be?

 

Very confused. Any known working examples anyone has would be great. Thanks
