Monitor Your System › How to Monitor a Security Cache in the Metrics Panel › Define Thresholds

Define Thresholds

Thresholds alert you visually when a cache becomes too large. You define thresholds for a caution state and a danger state. A cache that exceeds the caution state threshold is highlighted in yellow, and a cache that exceeds the danger threshold is highlighted in red. By defining thresholds, you know when a cache will be flushed soon. You are then prepared for any decreases in performance after the cache is flushed.

Follow these steps:

1. In the Metrics panel, click the cache that you want to monitor, and click Set Threshold.
2. Define the caution and danger thresholds by doing the following:
   1. Select Above on the Data Spikes drop-down list, and specify a value in kilobytes for the caution threshold.
   2. Select Above on the Data Spikes drop-down list, and specify a value in kilobytes for the danger threshold.
3. Click Set Threshold.

   The thresholds are defined. The cache is highlighted when the value exceeds the caution or danger threshold.
