As with Benoit above, I am also seeing the exact same issue.
I can receive a test email but no email for up/down nodes or Pools.
example output from my config:
alert BIGIP_GTMD_POOL_SNMP_STATUS_CHANGE_WHY_X "SNMP_TRAP: Pool .? state change .? --> red .*?" {
snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.41";
email toaddress="DL_Support@xxxx.com"
fromaddress="ltm01-xxxx"
body="Pool is DOWN, Investigate"
}
Running:
BIG-IP 11.3.0 3117.0
Surely it can't be that big of a job to have GUI options for configuring email alerts for VS/NODES/POOLS ?? It's a pretty basic ask and one that should have been nailed down in previous versions.
