Re: How to get samples over time?

[Frank L. <le...@us...>]

Eshan,

It turns out the "Performance InspectorTM" tool set: 
http://perfinsp.sourceforge.net/  provides a few tools that can plot IPC 
of an application over time.  The ptt tool allows you to specify a 
specific process for monitoring and you can identify the metrics as well 
as the intervals.  The cpi tool also allows for similar support for the 
entire system  Finally, the tracing mechanism used for Tprof allows for 
time or event based sampling which uses timestamps.  I think the VPA post 
processing tool may allow for views over time:

How to get samples over time?






Hi,

I was wondering if oprofile binds the samples with time information. I 
need to know relative time info of samples so that I can plot something 
like IPC of an application over time. What I can get now as a result is 
average over the whole sampling time.

I would appreciate a reply,

Ehsan
