Migrate from Standalone Nagios 3.5 and Nagios 4 to Checkmk CRE?

• Is there a way to import more objects like Host groups,service groups,contact groups etc. ?

Not via CSV import, but via WATO API. But you would still need to create rules that assign these groups to hosts and services.

@davidwayne

• How about performance data ? Can this be migrated or there is no straightforward way ?

It should be possible as the 1.6 raw edition also uses pnp4nagios for the graphs. Just copy the .xml and .rrd files to $OMD_ROOT/var/pnp4nagios/perfdata/….

@davidwayne

• What about Active checks ? Now, I should forget about the below checks as the Checkmk agent will have obviously more of them. Correct ?

Yes, most of the active checks will be superseded by agent based checks.

@davidwayne

• What about Custom Active checks and custom checks that run on the remote host (I don’t know what to call it) ? How can they be migrated as they have Nagios specific output ?

Custom active check plugins can be stored in $OMD_ROOT/local/lib/nagios/plugins and used with the ruleset “Classical active and passive monitoring checks”.

@davidwayne

• Notifications: This is quite different in Checkmk using WATO >> Notifications. Shall I set from scratch ?

The notification plugin scripts are quite compatible, the configuration is very different. Start from scratch.
