The net/munin,-server port

munin-server-2.0.76 – flexible network host monitoring, server (cvsweb github mirror)


Munin the monitoring tool surveys all your computers and
remembers what it saw. It presents all the information in graphs
through a web interface. Its emphasis is on plug and play
capabilities. After completing an installation a high number
of monitoring plugins will be playing with no more effort.

Using Munin you can easily monitor the performance of your
computers, networks, SANs, applications, weather measurements
and whatever comes to mind. It makes it easy to determine
"what's different today" when a performance problem crops up. It
makes it easy to see how you're doing capacity-wise on any

This package, munin-server, contains the files to install on a
server monitoring various machines running munin-node.

| Running ${PKGSTEM} on OpenBSD

After configuring at least one munin-node instance and adapting
${SYSCONFDIR}/munin/munin.conf as desired, you may run the periodic
tasks from cron with the following line:

*/5     *       *       *       *       su  -s /bin/sh _munin ${TRUEPREFIX}/bin/munin-cron

Log files in /var/log/munin will need to be rotated. Here is a sample
newsyslog.conf fragment:

/var/log/munin/munin-graph.log  _munin:_munin   644  7     250  *     Z
/var/log/munin/munin-html.log   _munin:_munin   644  7     250  *     Z
/var/log/munin/munin-limits.log _munin:_munin   644  7     250  *     Z
/var/log/munin/munin-update.log _munin:_munin   644  7     250  *     Z

Optionally you may want to use rrdcached to reduce disk I/O. Here is a sample
/etc/rc.conf.local part:
rrdcached_flags=-b /var/db/munin -l unix:/var/run/munin/rrdcached.sock -j /var/db/munin/journal -p /var/run/munin/rrdcached.pid -m 0660 -s _munin -w 1800 -z 1800 -f 3600 -F
Add www user to _munin group to grant write permissions on rrdcached socket.
