Resin Application Server Monitoring

Creating a new Resin server monitor

To create a new Resin server monitor, follow the steps given below:

  1. Click on New Monitor link.
  2. Select Resin Server under Application Servers.
  3. Give the Display name.
  4. Enter the Hostname of the server where Resin Application Server is running.
  5. Enter the JMX Port. For default installations of Resin, the JMX port number is 9999.
  6. You can enter your own credential details or select preconfigured credentials from details in Credentials Manager. If you wish to enter your own credentials, specify enter the JMX User Name and Password of Resin Server. If no authentication is required, then leave the fields blank.
  7. Enter the JNDI path. For example, JNDIPATH for default installations of Resin is /jmxrmi.
  8. Set the Polling interval.
  9. Choose the Monitor Group from the combo box with which, you want to associate Resin Server Monitor (optional). You can choose multiple groups to associate your monitor.
  10. Click Add Monitor(s). This discovers your Resin Server from the network and starts monitoring it.

Resin is a fast and reliable Java EE integrated high-performance application server that features load balancing for increased reliability. Built-in Resin features include clustering for high scalability, distributed caching to reduce reliance on traditional databases and adaptive health monitoring. Applications Manager increases the reliability of your Resin Application Server by monitoring all of the key performance indicators like thread details, connection pool usage, session details and memory resources.
