Pool downtime query

You can check the LTM logs using the following commands (this will show you when a pool member was marked up or down).

run util bash

cat /var/log/ltm | grep Pool | grep status
cat /var/log/ltm.1 | grep Pool | grep status
zcat /var/log/ltm*gz | grep Pool | grep status

 If you have a health check monitor applied to the pool, then you can also check its status.

For example:

show ltm monitor tcp tcp

This will provide output similar to the following:

--------------------------
 LTM::Monitor /Common/tcp
