RUT241 / RUT2M_R_00.07.09 snmp causing high CPU load

After installing RUT2M_R_00.07.09 on our RUT241, I started getting timeouts when pulling SNMP statistics. After inspection, it turned out that the snmpd daemon was causing issues - creating 100% CPU load. Disabling snmpd solved the issue. I’ve rolled back to RUT2M_R_00.07.08.2 on our RUT241

On our RUTX50 and TRB140 devices, I do not see the same issue.

Hello,

Could you please clarify whether you are performing a full SNMP walk or simply requesting individual SNMP objects? Additionally, is there any pattern in the specific SNMP objects being requested? Understanding this might help us pinpoint whether the issue is related to a particular set of requests or if it occurs under specific conditions.

Best regards,

Hi,

I’m sorry for not getting back to you sooner. I’m using SNMP exporter from prometheus. It walks the following oid’s every 20 seconds with a 20s timeout:

This is a snippet from the snmp.yml config file for SNMP-exporter.

    walk:
    - 1.3.6.1.2.1.2
    - 1.3.6.1.2.1.25.1
    - 1.3.6.1.2.1.25.2
    - 1.3.6.1.2.1.31.1.1
    - 1.3.6.1.4.1.2021.10
    - 1.3.6.1.4.1.2021.11
    - 1.3.6.1.4.1.2021.4
    - 1.3.6.1.4.1.48690.1
    - 1.3.6.1.4.1.48690.10
    - 1.3.6.1.4.1.48690.11
    - 1.3.6.1.4.1.48690.2
    - 1.3.6.1.4.1.48690.3
    - 1.3.6.1.4.1.48690.4
    - 1.3.6.1.4.1.48690.5
    - 1.3.6.1.4.1.48690.8
    - 1.3.6.1.4.1.48690.9

I’m also pulling data from a RUTX50 running RUTX_R_00.07.09.1 and a = TRB140 running TRB1_R_00.07.09.1 without any problems.
