Actually, in ONTAP 9.6, there are ove 6800 event routes!
the "event route" commands have been depricated and replaced by a few others. Going to use it as an example though.
You could start by looking at
event route show -destinations asup
which indicates what is at least alerted to ASUP. You can decide what is important to you there. (ONTAP 9.6 = 271)
Then look at all the EMERGENCY routes:
event route show -severity EMERGENCY
These are the most critical. Again, you can choose what to look at. (ONTAP 9.6 = 246)
You could even look at the overlap of the two
event route show -severity EMERGENCY -destinations asup
You would see the list is much shorter (ONTAP 9.6 = 28).
Bottom line is this: You need to decide which are important to you as an ADMIN and your company to monitor.
Following the guide to setup email:
Configure for the SMTP server
event config modify -mail-server mailhost.your_domain -mail-from cluster_admin@your_domain
Create a destination (email address)
event notification destination create -name storage-admins -email your_email@your_domain
Add the destination to the "important-events" filter
event notification create -filter-name important-events -destinations storage_admins
See which events will be alerted on
event filter show -filter-name important-events
cluster1::*> event filter show -filter-name important-events
Filter Name Rule Rule Message Name SNMP Trap Type Severity
----------- -------- --------- ------------- --------------- --------
1 include * * EMERGENCY, ALERT
2 include callhome.* * ERROR
3 exclude * * *
3 entries were displayed.
So, any routes/events that are Severity EMERGENCY or ALERT (rule #1) or that are ERROR AND the message name begins with "callhome.*" (rule #2) will be sent
