livestatus socket permission

[Kevin Metz]

After you set juju set nagios enable_livestatus=true,
/var/lib/nagios3/livestatus is created with drw-rwS--- 2 nagios www-data 2 Sep 14 20:38
and a socket file is created. However, restarting nagios gives:

[1473885439] livestatus: Livestatus 1.2.2p3 by Mathias Kettner. Socket: '/var/lib/nagios3/livestatus/socket'

workaround: chmod 2771 /var/lib/nagios3/livestatus

This appears to be a packaging issue for mklivestatus, the charm doesn't set permissions at all. While we could update the charm to work around the perms, fixing the package would be a more long term plan.

Status changed to 'Confirmed' because the bug affects multiple users.

I don't think this is an issue with the check-mk package. I had a look and no where does it specify the socket to use, that's actually user configured when enabling - you need to add 'broker_module' config like the below to /etc/nagios3/nagios.cfg:

| broker_module=/usr/lib/check_mk/livestatus.o /var/lib/nagios3/livestatus/socket

Maybe the charm (or whatever configures livestatus) move the socket to /var/run?

[Xav Paice (xavpaice)]

In https://git.launchpad.net/nagios-charm/tree/hooks/install the Nagios charm creates the mklivestatus directory and sets perms. We will need to change this to add +x.
