Hi everyone,

I’m encountering an error with the centreon_cisco plugin while trying to monitor memory usage on a Cisco CBS350 switch (firmware version 3.4.0.17): UNKNOWN: Cannot find memory informations

Has anyone experienced this issue before? If so, are there known workarounds to retrieve memory metrics?

Details:

  • The plugin fails to fetch memory data via SNMP.

  • A custom script workaround might require privilege level 15 (full admin access), which is restrictive.

Questions:

  1. Is there a specific OID for memory monitoring on CBS350 switches running firmware 3.4.0.17?

  2. Are there alternative methods to monitor memory without requiring privilege level 15?

Any insights, scripts, or configuration tips would be greatly appreciated!

Thanks

 

hello

as far as I can see there is no specific plugin/connector from centreon for the Business serie for cisco

I can see that this equipement has a snmp view config, maybe the default view is not including the standard OID for basic system information (cpu, ram, etc...) 

Cisco Business 350 Series Switches Administration Guide - SNMP Cisco Business 350 Series Managed Switches] - Cisco

can you check if you can add a view with this root OID “.1.3.6.1”, they say on the documenation there should be a list with pre-defined OID

the exact OID for cisco memory is .1.3.6.1.4.1.9.9.48.1.1.1

 

you can also check with “snmpwalk” if this oid is available, here is an example with snmp v2

snmpwalk -v 2c -c yourcommunity yourip .1.3.6.1.4.1.9.9.48.1.1.1

if the command is not returning any value, try removing the last digit, if you don’t get anything at .1.3.6.1.4.1.9 then that means cisco has done something on that OS/Hardware that is not “cisco standard”

 

there is also this article from cisco forum that also talks about the views and give a link to the MIB for CBS How to get SNMP OIDs on CBS 350?? - Cisco Community

and from what I see in the mib, the CBS apparently use a “ciscoSB” mib, maybe it is the same mib as the “small business” connector, I looked inside the Mib in that article and couldn’t find any “memory” counters 

and the centreon host template for SB doesn’t include memory check, maybe there is no memory value in the snmp for this model

Hello,

 

I forgot about the SB plugin, thanks !!

I tried everything and it seems that there is no solution to get the memory usage on these devices.

Snmpwalk a lot of info but nothing about the memory.

 

Have a good day !
