How to add support of new sensors for new (unknow) device
Hello!
I am very interested in adding support of new device series to Observium - NetPing (www.netping.ru) - devices for monitoring server rooms and remote power management.
Could you please suggest how can I add support of the sensors for unknown (for Observium) devices?
I have access to SMNP MIBs of this divices and can read value of any sensors via SNMP. For example I know the OID to read the temperature from one of the sensons: .1.3.6.1.4.1.25728.8800.1.1.2.1 Could you please explain how can I show this temperature on a graph in Observium?
Thank you.
Hi Denis,
You first need to create an OS entry in "includes/definitions/os.inc.php" with either a sysDescr regular expression or a sysObjectID to match against. It's easy to understand once you see the existing definitions.
Then you need to add the MIB that the sensors are in to this definition, there are also examples of this in the definition file.
You can now create a file in "includes/discovery/sensors/" with the same name as the mib in lower case, for example "netping-sensors-mib.inc.php". In this file you need to walk the relevant tables on the device and call discover_sensor() for each sensor you find. There are lots of examples in the sensors directory.
Once you've written code to correctly tell Observium about sensors with discover_sensor(), Observium will automatically discover them and graph them the same way as all other sensors.
If you need any assistance, since the device is in Russian, our Russian developer Mikhail will be back in a week and a half and he will be able to help you in Russian.
