From 6d0a7e394eabd456f70c2f2f8e958b2343074360 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 7 Nov 2022 13:33:11 -0800 Subject: [PATCH] perf stat: Do not indent headers for JSON Currently --metric-only with --json indents header lines. This is not needed for JSON. $ perf stat -aA --metric-only -j true {"unit" : "GHz"}{"unit" : "insn per cycle"}{"unit" : "branch-misses of all branches"} {"cpu" : "0", {"metric-value" : "0.101"}{"metric-value" : "0.86"}{"metric-value" : "1.91"} {"cpu" : "1", {"metric-value" : "0.102"}{"metric-value" : "0.87"}{"metric-value" : "2.02"} {"cpu" : "2", {"metric-value" : "0.085"}{"metric-value" : "1.02"}{"metric-value" : "1.69"} ... Note that the other lines are broken JSON, but it will be handled later.
