\`doris_be_cpu\` is a real BE metric, defined in
\`be/src/common/metrics/system_metrics.cpp\` (also present on branch-2.1 /
branch-3.0 / branch-3.1 / master). It's a metric **family** exposed with labels
— the actual lines on the \`/metrics\` endpoint look like:
\`\`\`
doris_be_cpu{device=\"cpu0\",mode=\"user\"} 1234567
doris_be_cpu{device=\"cpu0\",mode=\"idle\"} 9876543
doris_be_cpu{device=\"cpu0\",mode=\"system\"} ...
... (modes:
user/nice/system/idle/iowait/irq/soft_irq/steal/guest/guest_nice)
doris_be_cpu{device=\"cpu1\",mode=\"user\"} ...
\`\`\`
If you grep \`doris_be_cpu\` against your BE \`/metrics\` output and see
nothing, it usually means the BE either doesn't have \`/proc/stat\` access
(e.g. constrained container) or system-metric collection is disabled. Could you
share a snippet of \`curl http://<be>:8040/metrics | grep cpu\` so we can
confirm whether the metric family is being emitted on 2.1.7-rc03?
