Thanks for the compliments!
Just to clarify, with profiles — are you looking for:
- Saving and loading entirely separate host lists, e.g. you monitor different sets of hosts at different times? Or...
- Grouping hosts within a single session so you can filter the view, e.g. all hosts are always monitored but you show/hide groups like "Servers", "Switches", "VPN"?
We already support the (a) via File > Export/Import Configuration: you can save your current setup to a .db file and load it back anytime. We could make this quicker with a recent configurations list. The (b) would be a different feature involving host groups or tags.
Regarding extended notifications (email, syslog, etc) — noted for the future, thank you!
