SNMP metrics for Pro3 processors


 

Has anybody got SNMP working to monitor metrics and health of a Pro3?? I tried setting this up on two different units, and every time I try an snmpwalk it crashes after a few seconds.? It seems like a bug in the SNMP server.? I reported this to Crestron support in February, but they haven't done anything about it.
?
I'm not really sure what kind of useful metrics this machine can provide.? That's why I wanted to start with a broad snmpwalk for OID 1.3.6.1.4.1.3212.? Perhaps if I knew what I was looking for I could target specific OIDs instead.


 

I have not, but Crestron documents the supported MIBs here:?

I have looked through all those MIBs using SnmpB browser and didn't find anything useful, beyond a few basics like model name, program name, software version.? I was hoping for CPU, memory, disk, network stats and digital and analog input values.? Sigh.? I don't understand why someone spent the time creating all these MIB files if this is all there is.

To check a marketing feature checkbox.? :)

They would NEVER do that.

I have been monitoring processors via SNMP for a while now. I monitor loads of CP3s and MC3s and a few DIN-AP3s and DMPS3s. I know the documentation is not great. Although I don't have access to any PRO3s the OIDs seem to be consistent with each processor series. The same OIDs work for 4-series as well.
?
The most useful ones I collect:
?
CPU Load (0-100%) : OID 1.3.6.1.2.1.25.3.3.1.2.1
Firmware Version: OID 1.3.6.1.4.1.3212.6.1.2.3.1.0
Processor Model: OID 1.3.6.1.4.1.3212.6.1.2.1
System Uptime: OID 1.3.6.1.4.1.3212.7.2.3.2.7.1.2.1
Time Zone: OID 1.3.6.1.4.1.3212.11.5.11.5.0
?
You can use snmpwalk to test what information the processor will report back, however SNMP is not enabled by default.
?
To enable it I use EasyConfig in Toolbox > Functions > SNMP configuration
?
You have to click Enable SNMP and then add a Manager IP. The processor will reboot twice. After that SNMP will work.
?
Also I discovered that you need relatively recent firmware to get the most useful information from the Processor. On CP3s it has to be at least v1.6 or higher.
?
Hope that helps.
