Usage

usage: check_hetzner_storage_box.py [-h] [-s STORAGE_BOX] [-u USER]
                                    [-p PASSWORD] [-w WARNING] [-c CRITICAL]

check_hetzner_storage_box is an Icinga/Nagios-compatible check that checks for
the free space of a storage box in your Hetzner Robot account and alerts upon
reasonable thresholds.

optional arguments:
  -h, --help            show this help message and exit
  -s STORAGE_BOX, --storage-box STORAGE_BOX
                        Enter the Storage Box ID. You can see this in your
                        Robot WebUI Storage Box overview (for ex. BX40 #<ID>).
  -u USER, --user USER  Enter the Hetzner Robot Webservice username.
  -p PASSWORD, --password PASSWORD
                        Enter the Hetzner Robot Webservice password.
  -w WARNING, --warning WARNING
                        Enter the WARNING threshold in percent (free).
  -c CRITICAL, --critical CRITICAL
                        Enter the CRITICAL threshold in percent (free).

With a WARNING treshold of 10.0% and CRITICAL treshold of 5.0% (default).

./check_hetzner_storage_box.py -s <STORAGE_BOX_ID> -u '<HETZNER_WS_USER>' -p '<HETZNER_WS_PASSWORD>'
OK - Free disk size of Storage Box #123456 (Backup-Box-1) is currently 59.6%

With own WARNING and CRITICAL tresholds.

./check_hetzner_storage_box.py -s <STORAGE_BOX_ID> -u '<HETZNER_WS_USER>' -p '<HETZNER_WS_PASSWORD>' -w 25 -c 15
CRITICAL - Free disk size of Storage Box #123457 (Backup-Box-2) is less than 15.0% of the quota!

Performance Data

The check also prints out performance data that can be used to generate some nice graphs in Icinga2 or any other tool. Here is what it looks like (exmaple):

OK -  The ... |Storage Box #123456=1470452.0MB;1843200.0;1945600.0;0;2048000.0
