Open Calm-Rock opened 8 months ago

Calm-Rock commented 8 months ago

Error related to pid when setting up OTel collector.

Example: error scraperhelper/scrapercontroller.go:213 Error scraping metrics {"kind": "receiver", "name": "hostmetrics", "data_type": "metrics", "error": "error reading parent pid for process \"systemd\" (pid 1): invalid pid 0; error reading parent pid for process \"kthreadd\" (pid 2): invalid pid 0; error reading username for process \"postgres\" (pid 56197): user: unknown userid 70; error reading username for process \"postgres\" (pid 495499): user: unknown userid 70; error reading username for process \"postgres\" (pid 786364): user: unknown userid 70; error reading username for process \"postgres\" (pid 830175): user: unknown userid 70; error reading username for process \"postgres\"

The error is related to scraping metrics, and it appears to involve processes such as "systemd," "kthreadd," and several instances of "postgres."

@srikanthccv do confirm once that this is a harmless error

Yes, this can be ignored and shouldn't cause any issues overall
