Re: [pcp] PCP playback process metrics from archives in human readable text format

[Linto Paul <lintopaul@xxxxxxxxx>]

Hi Nathan,

I'm looking at some output along the lines of what we get using collectl where we may get all proc metrics filtered for a process for specific time window especially in a readable format. pmdumptext was a close one but didn't find any options to filter by process name although I can specify the PID.

#collectl -sZ -i10:15 --procfilt ctqrtap --procopts m

# PID User S VmSize VmLck VmRSS VmData VmStk VmExe VmLib VmSwp MajF MinF Command

58646 tqagent S 4936K 0 2208K 952K 88K 184K 3100K 0 0 0 /opt/teamquest/manager/.bin/tqrtap

# collectl -p r2144630a217-20160608-000000.raw.gz --procanalyze -f /var/tmp/pp

Oh, there's also a pcp-pidstat(1) since pcp-3.11.4.
