This is a simple filesystem permissions issue, as you can see by these two
log messages:
May 26 07:09:35 grafana prometheus[43908]: ts=2023-05-26T07:09:35.475Z
caller=query_logger.go:113 level=error component=activeQueryTracker
msg="Failed to create directory for logging active queries"
May 26 07:09:35 grafana prometheus[43908]: ts=2023-05-26T07:09:35.475Z
caller=query_logger.go:91 level=error component=activeQueryTracker
msg="Error opening query log file" file=/var/lib/prometheus/queries.active
err="open /var/lib/prometheus/queries.active: no such file or directory"
Make sure that either /var/lib/prometheus already exists and is writable by
the process, or that /var/lib is writable by the process (so that it can
create the prometheus directory itself).
