Hi,

You can update observium’s database like this:

UPDATE devices

SET

    snmp_community  = '',

    snmp_authlevel  = 'authPriv',

    snmp_authname   = 'user',

    snmp_authpass   = 'pw_user',

    snmp_authalgo   = 'AuthAlgo like SHA, etc',

    snmp_cryptopass = 'pw_enc',

    snmp_cryptoalgo = 'Crypto Algo AES or something else',

    snmp_version    = 'v3'

WHERE hostname LIKE 'REGEXP for your hosts';

Restart the (web)service afterwards.  

Best regards

Betreff: [Observium] Updating SNMP Configuration for Existing Devices

Hi,

I am planning to migrate some of my hardware devices (rack equipment) from SNMPv2 to SNMPv3.

The devices are already configured in Observium. Is there a way to update the SNMP configuration for approximately 200 existing devices without having to open each device in the GUI and manually enter the SNMPv3 settings?

Thank you for your help.

Best regards,

Mit freundlichen Grüßen

Saleh Tibi
