option to toggle flamegraph to threaded view #39

Open ceeaspb opened 6 years ago

We often need to review individual threads for load balancing, utilisation, etc. Being able to toggle between the 2 views would be very useful. It would need source data in the perf script output according to stackcollapse-perf.pl.

USAGE: ./stackcollapse-perf.pl [options] infile > outfile

    --tid       # include TID and PID with process names [1]
...

[1] perf script must emit both PID and TIDs for these to work; eg, Linux < 4.1:
    perf script -f comm,pid,tid,cpu,time,event,ip,sym,dso,trace
    for Linux >= 4.1:
    perf script -F comm,pid,tid,cpu,time,event,ip,sym,dso,trace
