= Bacula Storage Daemon statistics =

== About ==
The [source:bacula_sd] plugin allows the [http://munin.projects.linpro.no/ munin] monitor to graph statistics of the [http://www.bacula.org Bacula] backup system. The bacula_sd plugin specifically charts the write throughput of the configured bacula-sd devices.

The plugin works by calling the bconsole program and screen scraping the output.

== Download ==
[https://trac.bawue.org/munin/browser/bacula_sd?format=txt bacula_sd]

== Installation ==
  1. Make sure the bconsole binary is accessible in your path and the status command works as expected.
  1. Copy or link the bacula_sd script into your munin-node plugin directory, usually {{{/etc/munin/plugins}}}.
  1. Configure the munin-node to run the bacula_sd plugin as user root or another user able to execute bconsole and connect to the director:
{{{
[bacula_*]
user root
}}}
  1. If you want the munin plugin to output the hostname of the storage daemon, set the munin environment variable report_hostname to yes:
{{{
[bacula_*]
user root
env.report_hostname yes
}}}
  1. Test the plugin by calling {{{munin-run bacula_sd config}}} and by executing {{{munin-run bacula_sd}}}. Both commands should output sensible data without failing.

== Notes ==
  * The plugin is best run on the same system as the director. This way, no network latency is introduced into the measurement as the connection is considered to be local.
  * Due to the nature of bconsole, the reported write speed at the beginning and the end of a backup job might be a bit off. In reality however, the monitored speed matches up nicely with the write throughput reported by bacula at the end of a spooling run.
  * Due to the same design limit and the low sampling accurace tape changes will introduce a certain impreciseness. For system monitoring purposes however this should be negligible.
