Cohabitation SNMP et CMA

Bonjour,

Notre serveur Windows était supervisé en SNMP, et les sondes étaient OK.

Sur ce serveur, nous avons mis en place l’agent CMA et les sondes SNMP oscillent depuis entre OK et UNKNOWN.

Est-ce que ces deux modes de supervision cohabitent bien ? Faut-il privilégier CMA ?

Merci !

Hello :)

Technically both can coexist, but this is not a recommended configuration in the long run. CMA is specifically designed to replace SNMP on Windows assets because:

  • Better security (no UDP 161 exposure)
  • Richer metrics (with the ability to more easily request improvements)
  • No dependency on the Windows SNMP service, which is deprecated and has never supported SNMPv3 (which provides authentication and encryption)

If you wish to keep both, you can:

  • Check the Windows SNMP service logs during UNKNOWN periods
  • Check whether the UNKNOWN timestamps correlate with CMA checks

Best regards
