http://bugzilla.opensuse.org/show_bug.cgi?id=1191413 Bug ID: 1191413 Summary: golang-github-prometheus-prometheus exceeds default nofiles Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: screening-team-bugs@suse.de Reporter: luizluca@tre-sc.jus.br QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hello, During db compression, prometheus failed with: caller=db.go:766 component=tsdb msg=reloadBlocks err="find blocks: open /var/lib/prometheus/metrics/: too many open files" (and many more of those) After I restarted prometheus, it was able to recover itself nicely. My prometheus instance is using 826 after a restart, with 581 being metric chunks/index/wal and 132 sockets: # ls -la /proc/6546/fd -l | wc -l 826 I increased prometheus db range to 1y. Maybe that was caused the fileno limit to be reached. I manually increased the default 1024 limitnofiles to 2048 but I think the service could consider a little bit more file limit by default for that service. -- You are receiving this mail because: You are on the CC list for the bug.
