WebSphere Agent Based Measures
Hi,
I'm new to dT and setting some dashboards up for WebSphere monitoring.
Is there a description of what the WebSphere Agent Based Measures are and what they do, and perhaps some recommended settings, rather than me having to work out what each one is? I've asked dT support by the don't have any documentation!
For example, at the moment I'm using EJB Concurrent live Count, and I an having to work out what the graph is showing.
Under series properties, scale x1, depending on the aggregation it seems to show vastly different things for a period of 1 hour:-
count = 5-7
Max 50
Average 50
Sum 245 - 343
I assume count shows the actual quantity of EJB. Should I be using count for all the other WebSphere Agent Based Measures?
Thanks
The description in the measure itself is your best 'first look' documentation. For the EJB Concurrent Live Count, it says "Number of concurrently Living EJBs". If you look in the Performance Counter section of the Measure Configuration screen, you'll note that this measure is based on the LiveCount Performance Counter, specifically the "Current" Statistics Value.
All this data is simply coming from Websphere, so the ideal description of these is from the WebSphere doc. That's part of the reason we didn't duplicate a lot of the description text.
You can even use the Browse Metrics... button in the Measure Configuration to look thru the various metrics that are available from Websphere, there could be others that we dont grab by default that may be of interest to you. Simply create a new measure to grab your metric of preference.
You're probably interested in the Max or Average value of this metric. Personally MAX is most interesting to me. Count is the number of data points that have been received over the last N timeframe. Useful when determining if an Average is a nice sampling.
