This is way late but I was able to work out a good couple of filters. The "?expandSubcollections=true" filter will work with many different F5 LTM objects. I like outputs to look pretty and this would not come out formatted nicely from bash so pipe that output! "| jq . -M"
This filters out ALL pool config attributes and expands all sub-collections to provide state for pool members, etc on one page:
curl -sk -u admin:admin https://localhost/mgmt/tm/ltm/pool?expandSubcollections=true | jq . -M
This filters out ALL pool and member stats on one page:
curl -sk -u admin:admin https://localhost/mgmt/tm/ltm/pool/stats?expandSubcollections=true | jq . -M
