Number of Users
The number of users tells you how many users are logged in to a given
system.
The MIB variables computerSystem, fileSystemBavail, and
fileSystemBsize from the hp-unix MIB provides the resource value to
the monitor.
To verify the number of users on the system, use the uptime (1)
command.
Alerts for number of users can be used to determine the best time to run
backups or other maintenance, or for load-balancing, to disallow more
than a certain number of users on a given system.
The minimum polling interval is 30 seconds. We recommend a longer
interval. Short polling intervals may adversely affect system
performance.
