Nagios Support Forum

I currently have my NagiosXI setup with our SAN via SNMP walk using MIBS,
if I delete or add drives, is there a way I can auto detect the changes and adjust accordingly?
or does the process need to be manual by deleting and adding the services?

You would probably be best manually managing this for a couple reasons. The largest reason is that rrd files that contain performance data on those drives cannot be easily altered to include or remove tracks needed for changes in drives. Whereas creating or removing individual services per drive, would avoid this issue entirely. If you wished to do some form of automated removal and adding of services, you should be able to script this with an snmp walk, comparing it to a previous scan, and adding or removing services as needed via the XI APIs or import directory for adding services. You could additionally create a service template so that all you need to add for import would be the service name, drive\oid to monitor, and the template to use.
