Your host is configured for agent and SNMP.
The error message comes from the timeout of the agent connect. Can you please remove/deactivate the configured agent?

Drakomorh · March 12, 2021, 12:00pm

Hi,

we configured no agent in this host:

:(.

Drakomorh · March 12, 2021, 7:06pm

Hi,

I think the key is :

can you check?

regards

Drakomorh · March 12, 2021, 7:12pm

Hi,

It look like the same with other host:

problems in python 3 to parse null or “” to integer?

regards

andreas-doehler · March 12, 2021, 9:22pm

Your first post was a completely different error message. Please don’t mix different problems.

The floating point error message comes from an UPS what produces no good data on the SNMP output and the last on is a switch with wrong implemented PoE MIB.

First you have to inspect the output of your devices. That is not a CMK 2 problem but more a generic problem with your devices. For instance if the switch is not PoE enabled but it has the capability then this error can be normal and you need to configure this check as an “forbidden” check for this device.

Drakomorh · March 15, 2021, 11:08am

Hi,

How can we configure this check as an "forbiden"check for our switch?

Regards.

Drakomorh · March 17, 2021, 1:34pm

Hi,
we try this rule but nothing change:

what is wrong?

regards

Drakomorh · March 22, 2021, 9:22am

Hi @andreas-doehler,

So sorry for mix this 2 checks. I had thowght thats the same error. sorry.

how do we can configurgure this check as an “forbidden” check for swich’s service?

for the other problem, in 1.6 cmk version it run ok. We dont know how fix. I think we will disble snmp and create custom checks for monitoring SAI.

regards

andreas-doehler · March 22, 2021, 9:23am

The rule you need to look for is “disabled checks”.
There you can define the check type you don’t want to discover on your switches.

Drakomorh · March 22, 2021, 10:05am

Hi,

this no work

something wrong?

regards
