Disabled LB pool returns an alert - disabledbyparent #285

Hello Gerhard,

In the scope of F5 load balancers monitoring, I've discovered a case for which I think the returned status is not the expected one. Indeed, we can disable 

[root@server ~]# /usr/lib64/nagios/plugins/check_nwc_health -V

As you can see, the pool has been disabled by the network team: pool /appX/pool_appXY is disabledbyparent

So this is an expected situation to have 0 active members for that pool. The expected result would be an OK state.

Some other info below, that could be useful. 

[root@server ~]# /usr/lib64/nagios/plugins/check_nwc_health --community xxx --hostname xxx --mode pool-complections --name /appX/pool_appXY -vvv | grep -i disabled
