Description

This template is used to monitor the JVM’s Uptime, Garbage collection, heap memory usage, and open file descriptors. Applicable on all the servers where JMX is enabled.

Prerequisites

Gateway should be up and running. The device should be reachable from Gateway. The device should be in managed state. The device should be JMX enabled. Device should contain JMX credentials.

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.
