SNMPwalk and SNMPtranslate help

[ajwhite0]

Hello,

I've been asked to retrieve the CPU and Memory utilisation via SNMP (SNMP_Exporter).

I'm on a Ubunut VM and I've downloaded these 2 MIB files into :  /usr/share/snmp/mibs/

CISCO-PROCESS-MIB
CISCO-MEMORY-POOL

I want to get the CPU and Memory utilisation from a number of switches.  This SNMPtranslate fails though, what am I doing wrong?

snmptranslate -On -IR -M + /usr/share/snmp/mibs/ -m +CISCO-PROCESS-MIB CISCO-PROCESS-MIB::cpmCPUTotalTable

https://github.com/librenms/librenms-mibs/blob/master/CISCO-PROCESS-MIB

Thanks

Make It simple

cd /usr/share/snmp/mibs

snmptranslate -On CISCO-PROCESS-MIB CISCO-PROCESS-MIB::cpmCPUTotalTable

Hi @Flavio Miranda 

I get:

/usr/share/snmp/mibs$ snmptranslate -On CISCO-PROCESS-MIB CISCO-PROCESS-MIB::cpmCPUTotalTable
CISCO-PROCESS-MIB: Unknown Object Identifier (Sub-id not found: (top) -> CISCO-PROCESS-MIB)

usr/share/snmp/mibs$ snmptranslate -On CISCO-PROCESS-MIB::cpmCPUTotalTable

It seems the command is repeating  CISCO-PROCESS-MIB

Thanks, I get this:

This site is good, which do you think gives me the CPU utilisation?  https://mibs.observium.org/mib/CISCO-PROCESS-MIB/
