Monit radvd process?

[sarkyscouser]

I'm currently having problems with unbound and radvd which I'm still diagnosing.  I think my ISP is having ipv6 issues but can't be sure (pppoe connection).

In the meantime I'd like to use monit to monitor and restart these services so that the family can remain online.

I've achieved this for unbound but find the monit documentation impenetrable so struggling to find the correct syntax to check that the radvd process is running.  As as service test I've tried:

Code Select Expand

check process not exist

And various similar strings but cannot get it to work.

For service settings I've identified the pid file and via ssh found a pluginctl command that successfully stops and starts radvd so I just need to sort the service test with some help please.
