    Yeah seems like the issue,
    We went with available-members but seems like Total Members are more accurate
    adding new command you can run
    tmsh show ltm pool | grep -B 11 "Total Members          : 0"  | grep "Ltm::Pool"

    please know you will need to update the exact spacing you have in the Total Members to the actual number added how it showed up on mine cli

Hey,
You can use the following command to show the pools without members
tmsh show ltm pool field-fmt | grep -B 2 "available-member-cnt 0" | grep "ltm pool"

you can tweak it to your needs

you should chekc which line the available-member-cnt is at and change the -B if needed

Thank you for your feedback!

Using that, i was still able to pull pools with members in the pool. 

Walking this backwards, I think I need to find the "total members" and queue my search on that. The available members or min active will show pools with members for whatever reason. 

Using your search, here is a pool with a member in the pool

Ltm::Pool: pzentws.dev.cardinalhealth.net-tcp7443-pool
---------------------------------------------------------------------------------------
Status
  Availability           : offline
  State                  : enabled
  Reason                 : The children pool member(s) are down
  Monitor                : https-cah-default
  Minimum Active Members : 0
  Priority Groups        : 0/0/0 (highest/current/lowest)
  Current Active Members : 0
  Available Members      : 0
  Total Members          : 1
  Total Requests         : 0
  Current Sessions       : 0

 

Pools with no members. 

Ltm::Pool: ecm3pl.qa.cardinalhealth.net-tcp3212-pool
---------------------------------------------------------------------------------------

  State                  : enabled

      Thank you! That did the trick! :)

      I was getting close yesterday but was still getting mixed results.
