Hi all,
we currently have a monitoring check that alerts us of a service-specific config file having changed more recently than the services last restart.
We retrieve the restart time via `systemctl show <service> --property=ActiveEnterTimestamp`.
Is there a comparably elegant way to retreive the reload timestamp?
To avoid confusion, by reload I do not mean `systemctl daemon-reload`, I mean `systemctl reload <service>`.
Alternatively, is there a way to let systemd handle the reloading of services on change of related config files?
You didn't say what systemd version you use (mine is 255)
systemctl show httpd | fgrep -i rel

So with a bit of awk you can get at it this way
failing that, every reload is actually done via an ExecReload command in the service file, so you could intercept this with your own command instead
NeedDaemonReload=no
Best,
