JOnAS monitor

Supported versions

NeoLoad supports all Jonas server versions marked as certified Java Enterprise Edition (J2EE).

Connection settings

Defining a monitor to a Jonas server requires the name or IP address of the machine to be monitored, as well as the connection port (the default port is 1099). The port is the Jonas server RMI connection port.

In addition to these settings, a valid user account must be provided if authentication is enabled (same account than the one used to connect to Jonas Administration Console). By default authentication is not enabled.

Create a JOnAS monitor

NeoLoad makes it possible to create a new monitor either using the monitored machine creation wizard, as described in Create and configure a monitored machine, or from an existing monitored machine, as described in Create and configure a monitor.

NeoLoad displays a list of the EARs (Enterprise Archive) and WARs (Web Application archive) deployed on the configured server. It then automatically selects the most appropriate counters for each of the selected applications.

Available counters

All Jonas counters are documented here. Depending on the Jonas version, some counters may be automatically hidden because they are not supported by this particular Jonas version.
