Basic Walk-Through
This section describes how to create a basic threshold for a single, system-wide variable: the number of logged-in users. Our threshold will tell Horizon to create an event when the number of logged-in users on the device exceeds two, and re-arm when it falls below two.
Before creating a threshold, you need to make sure you are collecting the metric against which you want to threshold.
Determine you are collecting metric
In this case, we have chosen a metric (number of logged-in users) that is collected by default. We are also using data collected via SNMP. (For information on other collectors, see Collectors.)
