Check SNMP Synology
Nagios/Icinga script to check Synology via SNMP
It's based on version 2.5 check_snmp_synology for nagios by Nicolas Ordonez https://exchange.nagios.org/directory/Plugins/Network-and-Systems-Management/Others/Synology-status/details
Due to timeouts and none of the solutions proposed in the comments of the initial script I rewrote the first SNMPWalk to a something similar to that used by version 1.1 of the same script. Added checks to USB-storage mounting an disk-usage
Usage
./check_snmp_synology [OPTION] -u [user] -p [pass] -h [hostname]
Options:
-u [snmp username] Username for SNMPv3
-p [snmp password] Password for SNMPv3
-2 [community name] Use SNMPv2 (no need user/password) & define community name (ex: public)
-h [hostname or IP](:port) Hostname or IP. You can also define a different port
-W [warning temp] Warning temperature (for disks & synology) (default 50)
-C [critical temp] Critical temperature (for disks & synology) (default 60)
-w [warning %] Warning storage usage percentage (default 80)
-c [critical %] Critical storage usage percentage (default 95)
-b Check USB-storage
-i Ignore DSM updates
-U Show informations about the connected UPS (only information, no control)
-v Verbose - print all informations about your Synology
Examples:
./check_snmp_synology -u admin -p 1234 -h nas.intranet
./check_snmp_synology -u admin -p 1234 -h nas.intranet -v
./check_snmp_synology -2 public -h nas.intranet
./check_snmp_synology -2 public -h nas.intranet:10161
