Hi,

I am trying to build som quick snmp-checks from Nagios to the ASR.

I want to be able to monitor the state of the temperature, hd, fan and power. I am really having trouble getting the right data from the box.

Anyone who did this with success?

Regards

Andreas

Hi Andreas,

I am not sure if the disk usage is available. For the rest you can use "CISCO-ENTITY-SENSOR-MIB" to retrieve sensor entity information.

Below are the OID's you should use:

entSensorValue - 1.3.6.1.4.1.9.9.91.1.1.1.1.4 - This will give you each of the sensor values for (Temp, Voltage, Fan Speed, etc...)

entSensorType - 1.3.6.1.4.1.9.9.91.1.1.1.1.1 - This variable indicates the type of data reported by the entSensorValue.

entPhysicalName - 1.3.6.1.2.1.47.1.1.1.1.7 - This is the textual name of the physical entity your querying so you can match it up with index value from above.

For example:

FAN speed

entPhysicalDescr

root@Slack:~# snmpwalk -v2c -c public obama 1.3.6.1.2.1.47.1.1.1.1.2 | grep -i "fan speed sensor"

SNMPv2-SMI::mib-2.47.1.1.1.1.2.6869781 = STRING: "Fan Speed Sensor"

SNMPv2-SMI::mib-2.47.1.1.1.1.2.11741762 = STRING: "Fan Speed Sensor"

entPhysicalName

i mean not just the community, but that the community belong to the SystemOwner.

so, for example, if i have the community public, the complete command would be:

"snmp-server community public SystemOwner"

having only "snmp-server community public" won't allow us to poll the environmental information.

Hi,

I have already tried this, but i dont get any match when i grep after power module or fan/speed. Is there any difference if the routers are powerd by -48vdc? The fans should still be able to monitor since they are located in the ASR9k Chassis?

XR version is 4.1.0.

Hi Andreas,

do you have asr9k-mgbl PIE installed?

do you have 9010 or 9006 chassis?

Does the community on the ASR has SystemOwner permissions attached to it?

Hi Alexei,

I'm able to get the power information but not the fan speed with 5.1.3. But I can get it with 5.3.4. I had "snmp-server community public SystemOwner" configured. Do you know the reason?

 

Thanks,

William
