Using CASE in DPL

[AntonioSousa]

When using DPL, namely in Logs Classic, we sometimes have to check and convert values.

One great example is converting trap severity OID values into their corresponding loglevel's in Dynatrace.

I have managed to make my first conversion, and it goes like this:

USING (INOUT "CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0":STRING ) | FIELDS_ADD( loglevel: (
case
 when COLUMN("CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0") == '1' then 'CRITICAL'
 when COLUMN("CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0") == '2' then 'ERROR'
 when COLUMN("CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0") == '3' then 'SEVERE'
 when COLUMN("CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0") == '4' then 'WARN'
 when COLUMN("CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0") == '5' then 'NOTICE'
 when COLUMN("CISCO-SMI::ciscoMgmt.311.1.1.2.1.17.0") == '6' then 'INFO'
 else "NONE"
end
) )

While I still want to confirm if these loglevel's are the best match, I believe it is pretty self-explanatory.
BTW, the Cisco definition is:

1—Critical
2—Major
3—Minor
4—Warning
5—Clear
6—Info
