Description

This template monitors Cassandra JVM related metrics. It is applicable on devices containing Cassandra application.

Prerequisites

Java should be installed on the device. Gateway should be up and running. The device should be reachable from Gateway. The device should be in managed state.

Metric Parameters

Metric Parameters
ParameterDescription
Frequency
  • Frequency is the interval in which you want to probe and collect metric data from the target device/resource
  • Frequency is defined in minutes (min).
  • Warning ThresholdIf the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user.
    Critical ThresholdIf the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user.
    AlertThe alert value can be set to either Yes or No. If it is Yes, then an alert message is sent to the user.
