Add snmp cpu value from cisco sg350x to host

[conehead]

Hi,
I am monitoring serveral cisco sg350x switches and some had a problem last week (high cpu) which i was not monitoring (services not detected during scanning).

I found out the oids in the meantime
CPU utilization for 5 minutes
.1.3.6.1.4.1.9.6.1.101.1.9.0
When i run an cmk --snmpget on the host checkmk returns the right value but how to get it to services on the host.
I searched the forum and found the below solution which suggest to create a “Classical active and passive Monitoring check
Add services manually to SNMP device - General - Checkmk Community

The problem: i am unable to find this classical active and passive page
Or is theire another solution?

Thanks in advance

Hi,
I have not much experience with this but created the following .py file after reading the documentation and copied it to the plugin directory:

register.snmp_section(
    name = "sg350cpu",
    detect = startswith(".1.3.6.1.2.1.1.1.0", "SG350X"),
    fetch = SNMPTree(
        base = '.1.3.6.1.4.1.9.6.1.101.1',
        oids = [
            '7.0', # last 5 seconds
            '8.0', # last 1 minute
            '9.0', # last 5 minutes
        ],
    ),
)

I guess i am doing something wrong … ?

Your snmp section is only the first step to a check.
It defines only where to get what data. Now the next step the check function needs to be defined.
In the linked article the points 2.6 to 2.11 are now important.
