SNMP on Juniper SRX Chassis Cluster does not show node1

Question

I am trying to monitor an SRX (345) chassis cluster, via SNMP. The JUNOS documentation suggests that doing snmpwalk over jnxContentsDescr on the primary node should return details about all nodes. In my case, it does not.

user@server:~# snmpwalk -v 2c -c 'XXXX' 172.18.1.145 jnxContentsDescr JUNIPER-MIB::jnxContentsDescr.1.1.0.0 = STRING: node0 midplane JUNIPER-MIB::jnxContentsDescr.2.1.0.0 = STRING: node0 PEM 0 JUNIPER-MIB::jnxContentsDescr.4.1.0.0 = STRING: node0 SRX340 Chassis fan 0 JUNIPER-MIB::jnxContentsDescr.7.1.0.0 = STRING: node0 FPC: FPC @ 0/*/* JUNIPER-MIB::jnxContentsDescr.8.1.1.0 = STRING: node0 PIC: 8xGE,8xGE SFP Base PIC @ 0/0/* JUNIPER-MIB::jnxContentsDescr.9.1.0.0 = STRING: node0 Routing Engine JUNIPER-MIB::jnxContentsDescr.9.1.1.0 = STRING: node0 USB Hub

I also seem to be missing metrics on things like node1 cpu usage and temperature.

Am I missing something here regarding how to monitor the second node of a cluster?

Answer 1

Having spent many weeks working with JTAC to find a solution... the answer was simply to reboot the node which is missing from the SNMP output.

I have set up a few SRX (345) clusters since having this issue and each time they have exhibited the fault. JTAC could not replicate so it's unlikely they will fix it.
