Re: ITM Agent Detections

Maybe a dedicated  hubTEMS/TEPS with just that agent?

The first thing is to make sure the TEMSes and TEPSes and communications 
are running with spare capacity. When a TEMS gets overloaded, a lot of 
time can pass before a specific result from an agent turns into an event 
and then seen by TEPS and then a TEP. The agent itself needs careful 
control. For example, if it is busy doing a historical data export - no 
other situation or real time request will be processed. I saw another case 
with 40 MISSING type situations that was really really slow.

Keep all the TEMS/TEPS tasks where there is a lot of spare time - good 
server capacity and most of the time not doing much. That will give you 
pretty good event response time.

That said - there are no specific controls or measurements toward that 
end. For long term interaction with R&D - they *should* create a RFE

That specific issue has not come up [in my experience] but it does sound 
interesting.

Another possibility is to avoid the TEMS/TEPS processing.  If the 
situation formula is simple enough you can use a private situation with 
the events being transmitted to Omnibus or an SNMP event. That completely 
eliminates the TEMS/TEPS processing time... Of course you need Omnibus or 
some other event receiver to get the event.

Hello All,
 
I have a customer that has a requirement to post any situation to the TEP 
within 20 seconds.  Don't laugh.. :) Sometimes, I can get a situation to 
post sooner than that between 8, 12 or even 16 seconds.  And sometimes 
that same situation can take over 60 seconds to post.  Is there a way to 
make the agent respond quicker by forcing it with a setting or any 
performance tuning I can do to the other components?
 
I glady appreciate your ideas and responses.
 
Regards,

Gregory R. Mendes
