How to detect the issue of CPU spike for Tableau cluster on Linux
Hi! Today I would like to share how I am detecting the problem of CPU spikes. This morning we had a few CPU spikes. So let’s check uptime 10:19:23 up 116 days, 12:13, 1 user, load average: 0.36, 0.81, 2.57 dmesg --human | tail -n 50 [Dec30 16:15] audit: type=1327 audit(1703952955.024:85698311): proctitle=”/var/opt/tableau/tableau_server/data/tabsvc/services/backgrounder_0.20231.23.0806.1229/bin/run-backgrounder” [ +0.631996] audit: type=1327 audit(1703952955.024:85698311): proctitle=”/var/opt/tableau/tableau_server/data/tabsvc/services/backgrounder_0.20231.23.0806.1229/bin/run-backgrounder” [ +0.002027] audit: type=1300 audit(1703952955.029:85698312): arch=c000003e syscall=42 success=yes exit=0 a0=47 a1=7f5bb5d4b5c0 a2=10 a3=6f8da items=0 ppid=91808 pid=67952 auid=4294967295 uid=991 gid=1087000453 euid=991 suid=991 fsuid=991 egid=1087000453 sgid=1087000453 fsgid=1087000453 tty=(none) ses=4294967295 comm=”pool-29-thread-” exe=”/opt/tableau/tableau_server/packages/bin.20231.23.0806.122
