Description

This template is applicable on devices that contain the Apache Flume application. This template monitors both the Channel and Sink related metrics.

Prerequisites

Java should be installed on the device.

How to Apply:

For Flume we have Instance Based Monitoring or Component Discovery Monitoring . In order to do that, we should add the following custom parameter:

application.component.name : Channel

application.component.name : Sink

application.component.name : Source

Create different monitors for different components in Instance based monitoring.

Only one component is allowed per monitor in Instance based monitoring.

We have three different types of Component Discovery Monitoring. They are:

For a single component :

ALL : ALL your instances will be monitored.

Expression : The Instance Names that match the expression will be monitored.

Manual Selection : With this option, you can select the desired instances while applying templates to the device.

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.
