OVPA (Performance Agent) And Normal Agent. How can we install OVPA in linux and Win environment

[Rajesh_K]

Need the diff between OVPA and Operation agent. And can someone help me with docs of installing and admin guide of OVPA. Can we get the Statistics to dashboards with OVPA ex: CPU, Mem performace?

In the lame words ,

OVPA ( Performance Agent ) is the software which collects and stores the performance metrics ( like CPU , Memory , Filesystem etc .. ) , you can view the collected data in graph like format though the Performance Manager software ..

OA ( Operations Agent ) monitors the Server Metrics like CPU , Memory , Filesystem and send the Alerts to the Operations Manager ( HPOM ) , you should use the policies to set the threshold , say if CPU exceeds 90% utilization send the alert ..

In earlier version , 7.x and 8.x series , you need to install the OA for monitoring the server parameters and then install PA if you want to view the data ..

Going forward , 11.x Series , Both OA and PA are clubbed together into a single software as OA ..

Refer http://support.openview.hp.com/selfsolve/manuals website for the manuals ..

Thanks Vidyasagar,

I have OM Agent version 11.x, so here i wanted to know "What statistics does OVPA collect?  Can we get to them from the dashboard?" and can OVPA collect any performance data that we could use to generate reports/graphs? without Performance Manager software.

What statistics does OVPA collect?

>> Attached doc ( ovpa-metrics.txt ) contains the list of metrics which OVPA collects ..

 Can we get to them from the dashboard? and can OVPA collect any performance data that we could use to generate reports/graphs? without Performance Manager software ?

>> Yes , with the OVPA you can collect any data in addition to what it collects ( You have to develop the class of your own using the Data Source Integration Technology , for more details refer the User Guide ) .. Also you can pull data without using the Performance Manager Software , there is an extract utility which helps you fetch the data ..

Below link would help you to fetch the data from the OVPA without using the Performance Manager :

I'm attaching the putty session log ( putty.log ) of the same once again , go through it ..

Thanks a lot for the info. I got what i was looking for.

Another thing can we get this kind of reports in graphical way?

[m_vidyasagar]

Nope, for the graphical reports you need to use the Performance Manager ..

HI Vidyasagar,

Could you please help me to get the information that how we can collect extra metrics from agent.

in my test servers I see that there are some extra agent processes i.e. "mweccolleng (extended collection engine)" are running and collecting metrics extra than global metrics.

I`m not sure how to pull this data in OVPM.

Can you please help.

Blow is the opcagt -status output from test server :

Hi Arihant,

The screenshot you attached shows a custom class of metrics: WINPERFREQUEST*.  I see there is dsi service is running in the opcagt status you have shared, which means that custom metrics are created using the DSI technology. Refer to the OA User Guide: https://softwaresupport.hpe.com/group/softwaresupport/search-result/-/facetsearch/document/KM02892277

Note that the above doc is for OA 12.xx , download the appropriate manual based on the version of agent in your env.

Cheers,

Priya
