Pool Member Logs

The message " Pool services now has available members" is repeated as many TMM processes you device has. Each TMM advertise that your pool member is not available, that is probably by design. In your case you have 4 tmm hence the 4 lines. you can check how many TMMs you have with this command: tmsh show sys tmm-info | grep Sys::TMM

In the syslog you won't see how many pool members are available, you will see if a specific member change to UP or Down and the same for the Pool, if a Pool is UP or Down.

If you need to see how many pool members are up you better use SNMP.
