Background
My latest gizmo in the basement is a Netgear ReadyNAS RN104. Of cource I want to monitor it so I can be sure that it is healthy. This article describe howto monitor the RN104 by using SNMP.
The implementation monitors:
- Disk status/temperature
- CPU temperature
- Fan status/speed
- Network status
- Admin GUI status
The result.
The result of the implemantion can be seen below, of course is the data collected graphed if it is possible.
The implementation
As op5 Monitor has a new concept called management packs I have choosen to implement it as a management pack. For a Nagios user it means that I have put the services in a hostgroup instead of directly at the host.
If you are running op5 Monitor, it is extremly simple to implement because I have created a management pack which is downloadable from op5. Just download the json file and upload it to your op5 system using the managament pack manager.
