List nodes that are down

Kevin: while I don't have a perl script handy to paste, hopefully this will help get you off to a good start or give you an extra idea or two.

 

 

-- Point SOAP::Lite at LocalLB.NodeAddress

 

-- Use the get_object_status call, which will return two useful bits of data for you: availability_status, and enabled_status

 

-- Other calls of interest (depending on your goals) may be get_availability_status and get_monitor_status

 

 

You can fetch a list of node addresses with get_list, stuff them into an array, then pass that entire array into one of the calls above. With the results, create a hash with the node address as the key, and the results of one of the 'status' calls above as the value. Then you'll have something solid to work with and you'll be able to do pretty much whatever you're after.

 

 

Regarding emails when a node goes down, you may want to have BigIP itself handle this via SNMP traps. Refer to the manual for your version on how to do this - a pool member or node address going offline should be already included on box, so it's a matter of setting it up.
