AppDynamics Extension for Resin Monitoring

This extension works only with the standalone machine agent.

 

Use Case

Resin is a high-performance, scalable Java application server. This eXtension monitors Resin instance and collects useful statistics exposed through MBeans and reports to AppDynamics Controller.

 

Prerequisites

  1. Before the extension is installed, the prerequisites mentioned here need to be met. Please do not proceed with the extension installation if the specified prerequisites are not met.
  2. To use this extension please configure JMX in your instance. For information on enabling JMX, please refer to http://caucho.com/resin-4.0/admin/resin-admin-console.xtp#JMXConsole.

Example Configuration

    <server-multi id-prefix="app-" address-list="${app_servers}" port="6800">
      <jvm-arg>-Dcom.sun.management.jmxremote.port=9999</jvm-arg>
      <jvm-arg>-Dcom.sun.management.jmxremote.ssl=false</jvm-arg>
      <jvm-arg>-Dcom.sun.management.jmxremote.password.file=/home/AppDynamics/Resin/jmxremote.password</jvm-arg>
    </server-multi>

Installation

  1. Download and Unzip ResinMonitor.zip to <MACHINE_AGENT_HOME>/monitors/
  2. Configure the extension by referring to the below section.
  3. Restart the Machine Agent.

 

Configuration

Note : Please make sure not to use tab (\t) while editing yaml files. You can validate the yaml file using a yaml validator

  1. Edit the file config.yml located at <MachineAgent_Dir>/monitors/ResinMonitor The metricPrefix of the extension has to be configured as specified here. Please make sure that the right metricPrefix is chosen based on your machine agent deployment, otherwise this could lead to metrics not being visible in the controller.
  2. Specify the Resin instance host, JMX port, username and password in the config.yml. Configure the MBeans for this extension to report the metrics to Controller. By default, "resin" is the domain name. Specify the keyproperty 'type' of MBeans you are interested. Resin MBean ObjectName is of the form 'resin:name=name,type=type,Host=name,WebApp=name'. Please refer here for detailed Resin MBean Names. You can also add excludePatterns (regex) to exclude any metric tree from showing up in the AppDynamics controller.

    For eg.

        # Resin instance
        server:
            host: "localhost"
            port: 9999
            username: "monitorRole"
            password: "admin"
    
        # Resin MBeans
          mbeans:
              domainName: "resin"
              types: [CacheStore,ClusterServer,ConnectionPool,Memory,Server,ThreadPool,TransactionManager,WebApp]
              # Uses regular expressions to match the pattern
              excludePatterns: [.*ClusterIndex$]
    
          #prefix used to show up metrics in AppDynamics
          metricPrefix:  "Custom Metrics|Resin|"
    
    

    In the above config file, metrics are being pulled from the specified MBeans. Note that the patterns mentioned in the "excludePatterns" will be excluded from showing up in the AppDynamics Metric Browser.

  3. Configure the path to the config.yml file by editing the in the monitor.xml file in the <MACHINE_AGENT_HOME>/monitors/ResinMonitor/ directory. Below is the sample

     <task-arguments>
         <!-- config file-->
         <argument name="config-file" is-required="true" default-value="monitors/ResinMonitor/config.yml" />
          ....
     </task-arguments>
