tmsh show ltm pool  members

Look under each member for the Reason which will have a time stamp at the end for the last time the state changed e.g.

  --------------------------------------------------------------
  | Ltm::Pool Member: memberA:80
  --------------------------------------------------------------
  | Status
  |   Availability   : offline
  |   State          : enabled
  |   Reason         : tcp: No successful responses received before deadline. @2017/08/29 17:44:39.
  |   Monitor        : tcp_half_open
