Each threshold is a combination of condition and events pair — if condition becomes true, associated "activation" event generated, and when it's becomes false again, "deactivation" event generated. Thresholds let you take a proactive approach to network management. You can define thresholds for any data collection items that you are monitoring. When setting thresholds, first determine what would constitute reasonable thresholds. To decide on a threshold value, you need to know what is normal value and what is out of range. Only you can decide what is normal behavior for a device on your network. Generally, we recommend that you collect information about a device throughout one complete business cycle, before determining the normal high/low range. Consider collecting values such as error rates, retry limits, collisions, throughput, relation rates, and many more. You also have the possibility to define more than one threshold for a single DCI, which allows you to distinguish between different severity conditions.
