email alerts for down nodes

Here's what works for me - it's general for all pool members, but it works while we're working on getting our Vantage system to monitor the F5s.

alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_STATUS {
snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.10";
email toaddress="someone@here.com, someoneelse@here.com, anotherguy@here.com"
fromaddress="root"
body="Critical: Pool member monitor status down."
}
alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_STATUS_UP {
    snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.11";
    email toaddress="someone@here.com, someoneelse@here.com, anotherguy@here.com"
    fromaddress="root"
    body="Critical: Pool member monitor status up."
}

The subject for an email notice then looks like this: 01070638:5: Pool /Common/pool_prod_membername member /Common/nodename:9083 monitor status down. [ was up for 0hr:3mins:46sec ] (slot1) where membername is the specific pool member's name and nodename is the node's name (obfuscated by me for security reasons).

Hope this helps...
