eG Agents Test

To receive precise, real-time updates on the performance and overall health of the components being monitored, administrators need to ensure that the eG agents, which perform the actual monitoring functions, are installed in the environment and are running at all times. This test periodically monitors the status of agents to report whether they are installed or not, and if installed, whether/not they are running.

Target of the test : The eG Manager

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the eG manager being monitored.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed .

Host

The host for which the test is to be configured.

Port

The port number at which the specified host listens.

JMX Remote Port

Here, specify the port at which the JMX listens for requests from remote hosts. In the <EG_MANAGER_INSTALL_DIR>\manager directory (on Windows; on Unix, this will be the /opt/egurkha/manager directory) of the eG manager, you will find a management.properties file. Set the port defined against the com.sun.management.jmxremote.port parameter of the file as the JMX Remote Port.

User, Password, and Confirm Password

By default, JMX requires no authentication or security. Therefore, the User, Password , and Confirm Password parameters are set to none by default.

JNDIName

The JNDIName is a lookup name for connecting to the JMX connector. By default, this is jmxrmi. If you have registered the JMX connector in the RMI registry using a different lookup name, then you can change this default value to reflect the same.

JMX Provider

This test uses a JMX Provider to access the MBean attributes of the eG manager and collect metrics. Specify the package name of this JMX Provider here. By default, this is set to com.sun.jmx.remote.protocol.

Timeout

Specify the duration (in seconds) for which this test should wait for a response from the eG manager. If there is no response from the eG manager beyond the configured duration, the test will timeout. By default, this is set to 240 seconds.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total agents

Indicates the total number of agents configured in the eG manager.

Number

 

Not running agents

Indicates the number of agents that are not running currently.

 

Number

An agent that is not running will not be able to collect metrics from the components assigned to it for monitoring. Without metrics, the eG manager will have no basis for determining the state of the related components, and will hence be forced to attach an Unknown state to all components monitored by that agent.

Use the detailed diagnosis of this measure to identify the agents that are not currently running.

Not installed agents

Indicates the number of agents that have not been installed.

Number

While actively using the eG Enterprise Suite, you may come across situations where an agent is configured in the eG manager for monitoring one/more components, but the agent software is not physically deployed on a host. The value of this measure is indicative of how many such configured but not installed agents are available in the environment.

Such agents again will not be able to extract performance statistics from components. These components will hence assume the Unknown state, until the agent is physically deployed and started.

Use the detailed diagnosis of this measure to know which agents are yet to be installed.

The detailed diagnosis of the Not running agents measure lists the IP address/nick name of the eG agents that are not running currently.
