there is field-fmt option which may be easier to grep.

  field-fmt       Show statistics in field format for the specified items

e.g.

root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) show ltm pool all members field-fmt |grep "ltm\ pool\|active-member-cnt\|addr\|monitor-status"
ltm pool foo {
    active-member-cnt 1
            addr 200.200.200.101
            monitor-status up
ltm pool qux {
    active-member-cnt 0
            addr 200.200.200.111
            monitor-status unchecked

The command that nitass recommends is correct for interactive use. For up/down status, it won't be useful, but be aware of the 'raw' option - this'll give you the actual value of counters rather than one rounded to the nearest kilo/mega/giga. For doing this same thing in a tmsh script, you'll need to modify it to use 'tmsh::get_status' rather than 'show', and then drop 'field-fmt' as it is silently specified automatically. 'raw' however is not so it might still come in handy when working with statistics rather than states.
