2 Discovering Apache Tomcat Target

This chapter describes how to discover your Apache Tomcat target with Enterprise Manager Cloud Control.

The following topics are provided:

Discovering Apache Tomcat Targets

After successfully deploying the plug-in, follow these steps to add the plug-in target to Cloud Control for central monitoring and management:

  1. Log in to Enterprise Manager Cloud Control.
  2. Click Setup, then Add Targets, and finally Add Targets Manually.
  3. Select Add Non-Host Targets by Specifying Target Monitoring Properties. From the Target Type drop-down, select the Apache Tomcat target type. Click Add Manually.
  4. On the Add Apache Tomcat page, provide the following information for the properties:
    • Host: Host of the Apache Tomcat instance. This property is always required.
    • JMX Port Number: Remote JMX port. This property is always required.
    • JMX User Name: Required when authentication is enabled for JMX.
    • JMX Password: Required when authentication is enabled for JMX.
    • Communication Protocol: Communication protocol used by remote JMX client. Do not change the default value specified unless the remote JMX implementation has changed.
    • Service Name: JMX service name. Do not change the default value specified unless the remote JMX implementation has changed.
    • SSL Trust Store: Required when SSL is enabled for Apache Tomcat.
    • SSL Trust Store JMX Password: Required when SSL is enabled for Apache Tomcat.
    • Apache Tomcat Version: Version of Apache Tomcat (for example, 7.0, 6.0, 5.5.23, etc.). This property is always required and is used to determine the specific performance metrics to be monitored and/or collected.

    Note:

    You must not change the default values of Communication Protocol and Service Name unless the remote JMX implementation has changed.

After deploying and configuring the plug-in to monitor one or more targets in the environment, you can customize the monitoring settings of the plug-in. This alters the collection intervals and threshold settings of the metrics to meet specific needs of your environment. If you decide to disable one or more metric collections, this could impact the reports that the metric is a part of.

Verifying and Validating the Plug-in

After waiting for a few minutes for the plug-in to start collecting data, use the following steps to verify and validate that Cloud Control is properly monitoring the plug-in target:

  1. On the Agent home page, from the Monitored Targets table, click the Apache Tomcat target link.

    The Apache Tomcat home page appears.

  2. Verify that no metric collection errors are reported in the Alerts section.
  3. Ensure that reports can be seen and no errors are reported by selecting the Reports property page.
