Hello,

I try to use the pass-manger to inject the credentials of the tape-library from Hashicorp Vault. The credentials will be pulled, but not mapped to snmp-options (like “--snmp-username”; “--privpassphrase”; “--authpassphrase”). 

I have also checked the topic Using --pass-manager options and the provider hashicorp vault | Community (centreon.com)

Error Message: 

UNKNOWN: Missing parameter Security Name.

I hope anyone can help me…

regards,

Solved: As value in the map-option parameter the variable of the plugin (Github source snmpv3) has to be used.

 

  --map-option="snmp_auth_passphrase=%{value_inf-icinga/data/library}" \
  --map-option="snmp_priv_passphrase=%{value_inf-icinga/data/library}" \
  --map-option="snmp_security_name=%{key_inf-icinga/data/library}"
