Email notification of node/vs down
Alertd appears to be the method of sending an email alert; how do I tell it a node is down?
Or a custom scripted monitor looked like a candidate.
I am not necessarily looking for the solution - just guidance of where to investigate further.

- HamishCirrocumulusWell... If you don't want to workout what the OID will be, you could always watch the traps come out using tcpdump or wireshark or similar (tcpdump on the F5 linux host would be better, then transfer the dump file to something with wireshark on it). Find the trap for the event you want to alert for and copy the OID from it.
- e71joy_25623Nimbostratushi Hamish,
- HamishCirrocumulusOn the linux host (i.e. ssh into the F5, or go in via the console for bash shell command line access) and type

hello Hamish,
- HamishCirrocumulusYou need to find whether the problem is with the traps not going out, or the tcpdump not capturing the packets. Is the file completely empty?

Instead of mucking with syslog configs on the load balancer itself (which IMO this obvious request of an email alert when a node, pool, or critical event should never have to be implemented at a CLI level on each individual BIGIP box with the premimium people pay for F5 devices), try using SEC. Just parse the SNMP traps from the F5 box on the server running SEC to trigger the event you want...basically to see the trap...parse it...then shell out and email you of the event)...why this is still not a part of EM I do not know...
