This alert appears in the Other Category when triggered. This alert has PerCluster, PerService, PerCache and overrides. Caches and services are named, and clusters are represented by their named monitoring connection. The tier can be front, where appropriate, or back. The rate is for a given tier of a cache for a given service in a cluster. By default the alert is disabled with the following default settings: Warning is 100 (total objects), Alarm is 200 (total objects) and Duration is 60 (total objects).Įxecutes when the Misses per second exceed the specified threshold and duration. This alert is executed when the current Hit% (total current hits/total current gets) is below the specified threshold for a sampling period and the specified cache(s).Ī single alert is executed when the CacheQueueSize for all nodes in the cluster exceeds the specified thresholds. The default time range setting is 5 minutes (300 seconds), the warning default setting is 40 (percent) and the alarm default setting is 50 (percent). To specify the time range, modify the $BAD_COMMUNICATION_NODES_TIME_RANGE The warning default setting is 115 (percent) of the previous 24 hours and the alarm default setting is 125 (percent) of the previous 24 hours.Ī single alert is executed if the average communication failure rate of all nodes in the cluster exceeds the specified thresholds.įor each node in the cluster, an alert is executed if the communication failure rate for that node exceeds the specified thresholds.Įxecutes a single warning and a single alert if the percentage of nodes in a cluster exceeds the specified threshold for the BadCommunicationNode alert within a time range specified. NOTE: The 24 hour time span (86400 seconds) is controlled by the $AVERAGE_MEMORY_TIME_WINDOW substitution. For example, if the threshold is set to 50% of total memory used, and the average memory consumption on a particular node for the previous 24 hours is 40%, an alert will be executed if current memory usage exceeds 60% of the total. A single alert is executed if the average percent memory used over max memory of all nodes in the cluster exceeds the specified thresholds.įor each node in the cluster, an alert is executed if the percent memory used over max memory available for that node exceeds the specified thresholds.įor each node in the cluster, an alert is executed if the percent memory used exceeds the specified threshold for the percent above average memory used in the previous 24 hours.
