Subject: [PATCHSET 00/15] perf stat: Improve perf stat output (v2)
Date: Wed, 23 Nov 2022 10:01:53 -0800 [thread overview]
Message-ID: <20221123180208.2068936-1-namhyung@kernel.org> (raw)
Hello,
This is a continuation of my perf stat cleanup work focusing on the
metric-only mode with JSON output now. It's based on the previous
patchset which is already merged to acme/perf/core.
The JSON output + metric-only with aggregation has been broken for a
while. The last update fixed the crash but it still produced invalid
JSON objects. Also having a separate header and objects with their own
"metric-value" key is not convenient to process.
# perf stat -aj --metric-only --per-socket sleep 1
{"unit" : "GHz"}{"unit" : "insn per cycle"}{"unit" : "branch-misses of all branches"}
{"socket" : "S0", "aggregate-number" : 8, {"metric-value" : "0.809"}{"metric-value" : "2.10"}{"metric-value" : "0.37"}
So I removed the header and move the metric keys to the object. Then
it doesn't need separate objects anymore. The new output looks like:
# perf stat -aj --metric-only --per-socket sleep 1
{"socket" : "S0", "cpu-count" : 8, "GHz" : "0.817", "insn per cycle" : "2.15", "branch-misses of all branches" : "0.38"}
You can get it from 'perf/stat-display-v2' branch in
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks,
Namhyung
