I'm setting up remote monitoring of postgres, but running into an uncomfortable situation with permissions.
Basically it seems hard to set up a secure "read only" role, yet also allow proper monitoring.
A brief writeup of that is here:
http://help.logicmonitor.com/installation-getting-started/notes-for-monitoring-specific-types-of-hosts/databases/postgresql/postgresql-credentials/
In order to get accurate server busy stats and max query time, the LogicMonitor user needs to be a superuser "alter role logicmonitor superuser;". Without the SuperUser privilege, all servers will appear busy, and maximum query time will always be 0.
Is there a way to grant the type of permission needed to view stats, without superuser?
