This is an iApp that collects some information from the user with the intent of keeping the members of a GTM or LTM pool object synchronized against the result of a DNS lookup. Users provide:
name of the pool
type: gtm or ltm
if gtm, what datacenter it should be in
what nameserver to query
how often to query
what hostnames to lookup
what port to use when creating the pool members
This creates a periodic handler that runs at the specified interval, using the results of "dig" against the specified nameserver for the hostnames to create/modify the specified pool.
Note: For the sake of keeping the demo simple, the script doesn't handle error/empty/timeout responses from the nameserver.
