Munin plugin for Tarsnap | ||
======================== | ||
|
||
https://github.com/warrenguy/munin-tarsnap | ||
|
||
This plugin creates two graphs: | ||
|
||
* *tarsnap_total* - summarising the total amount of data the local tarsnap | ||
instance has stored on the service (total and compressed). | ||
* *tarsnap_unique* - summarising the total amount of unique (deduplicated) | ||
data the local tarsnap instance has stored on the service (total and | ||
compressed). The compressed value here is the actual amount of data stored | ||
on the tarnap servers and what tarsnap uses for billing. | ||
|
||
Usage | ||
----- | ||
|
||
Add the following to your backup script (after tarsnap has run), or to a | ||
cron job: | ||
|
||
/usr/local/bin/tarsnap --print-stats > /path/to/tarsnap-stats.txt | ||
|
||
N.B.: ensure `/path/to/munin-stats.txt` is readable by munin-node. | ||
|
||
Configuration | ||
------------- | ||
|
||
Define the path to the stats file created above in your munin-node | ||
configuration: | ||
|
||
[tarsnap] | ||
env.STATSFILE /path/to/tarsnap-stats.txt | ||
|
||
The default value is `/var/lib/munin/tarsnap-stats.txt`. | ||
