This is a silly argument. When things are failing that's precisely
when you need your monitoring system to work. Of course you are
interested in the fact that you're out of connections but you're
trying to figure out *why* you're out of connections. Maybe you have
queries consuming all iops, maybe disks have filled up and that's
cascaded into a postgres problem, maybe you have lots of similar
queries running, etc.
The first step in debugging is always gathering data which is why it's
so frustrating if the first thing to go down is your monitoring
software.
