Re: grafana rc.d scripts reports process not running

I'm currently trying out grafana, and I noticed one weirdness after
starting it using the pkgsrc rc.d script.

# /etc/rc.d/grafana status
grafana is not running.
# cat /var/run/grafana.pid
21719# ps -auxwww | grep 21719

grafana 21719  0.0  0.1   1681352 157636 pts/4  Sl    3:08nachm.    0:02.15 grafana server -homepath /usr/pkg/share/grafana -config /usr/pkg/etc/grafana.conf -pidfile /var/run/grafana.pid

So grafana saved its PID into /var/run/grafana.pid, which is what's
configured in the rc.d script as pidfile, but the status command
thinks it's not running, despite a grafana process with the
corresponding PID running. (I tried manually adding a newline to the
pidfile, but that doesn't change the behaviour.)

There is not even an interpreter involved, /usr/pkg/bin/grafana is a
go binary.

Does anyone have an idea what the problem could be here?

grafana rc.d script attached.


A way to check for a process-name different from the command-name seems
to be documented in /etc/rc.subr. Does this patch work?
