How to sniff node down

Thanks for your response. It looks like the answer I was looking for is the BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_DOWN event. I didn't find it anywhere in the documentation regarding nodes. I wanted to find a NODE_DOWN event in iRules that I could program around to send me the notification when that event was raised and judging from the name I'll assume that's it.

 

 

Thanks.
