Foglight for JMX 5.9.8 - User Guide

Foglight for JMX System Requirements Installing Foglight for JMX Managing JMX Agents Managing MBean Server Models Monitoring and Investigating JMX Data

Creating JMX Agents

After installing the cartridge file, you must create and configure one or more JMX agents. These agents are responsible for collecting performance and monitoring data from the JMX application servers. JMX agents can be located either on the same machine as the resources they monitor, to collect data locally, or hosted on an Agent Manager on a remote machine, for remote collection. In both cases, an Agent Manager is required to collect the data from the agent.

You can create JMX Agents using the Connection URL through the Setup agent wizard on the Application Servers Administration dashboard. In this case, do not deploy the agent package or create agents through the Agent Status dashboard. The Setup agent wizard performs these tasks for you as part of the agent creation process. For more information, see Creating JMX Agents Using the Connection URL.

You can also create JMX Agents that use the JMX Discovery Agent to do Local Process Discovery. In order to use local process discovery, you must first create and activate the Discovery Agent through the Agent Status dashboard, then create the JMX Agent through the Setup agent wizard. For more information, see Creating JMX Agents Using Local Process Discovery.

Creating JMX Agents Using the Connection URL

1
On the navigation panel, under Dashboards, click Application Servers > Administration.
3
Select JMX (Connection URL).
5
Optional — Use the Connection Info Assistant to generate the Service URL needed to connect with the MBean server you want to monitor.
a
Click Connection Info Assistant.
For example, select JMX RMI (JBoss 7, Glassfish, Tomcat, Resin) to configure a generic platform MBean server connection. The dialog box refreshes. Host and Port appear in the list of properties.
c
Click the Value field for the property you want to edit and type a new value.
d
In the Service URL box, type the service URL of the MBean server. For example:
where {hostname} and {port} are specific to the MBean server you have chosen.
Click Next.
If the MBean server has security enabled and requires credentials to access it, click the Use credentials check box. If you have not already configured credentials for the JMX agent, you are prompted to do so. For more information about credentials, see the topic “Controlling System Access with Credentials” in the Foglight Administration and Configuration guide or help.
Click Next.
Click Next.
To use an existing group, select the Assign the following Server Group option, then select the group from the list.
To create a new group, select the Assign the following Server Group option, and select Define new group from the list. In the Name box, type the name of the new group.
Click Next.
In the Specify a name for your agent box at the bottom of the screen, type a name for the agent you are creating.

Click Finish.
View data collected by the agent in the Application Servers > Monitor dashboard. See the Monitoring Application Servers User and Reference Guide or help for more information.

Creating JMX Agents Using Local Process Discovery

Before you can create a JMX agent using local process discovery, you must first deploy the JMX Discovery Agent package to create a Discovery Agent on the monitored host. After the Discovery Agent is running and collecting data, you can discover monitored processes on hosts.

Creating a JMX Agent using local process discovery is a three-step process. Complete the procedures in the following sections in order:

Deploying the JMX Discovery Agent Package

In addition to the JMX agent, Foglight for JMX also includes a JMX Discovery Agent that you can use to discover processes on a monitored host. If you intend to use local process discovery, you must first deploy the JMX Discovery Agent to the appropriate hosts.

The process for deploying the JMX Discovery Agent is the same as it was in previous versions.

1
On the navigation panel, under Dashboards, click Administration > Agents > Agent Status.
3
In the HostSelector box, select the monitored host, and then click Next.
4
In the Agent Packages box, select the JMX Discovery Agent package: JMXDiscoveryAgent.gar, and then click Next.
5
View your selections in Summary, and then click Finish.

Next, create and activate the Discovery Agent.
