Monitoring TA Java Application Performance

JConsole, a GUI-based software, does not provide a way to capture performance data in a non-interactive way. To capture JMX MBean Attribute values as displayed below, for the purposes of generating alarms when the software exceeds thresholds, use these command-line alternatives to the JConsole.

• Jmxterm

• cmdline-jmxclient

Note: jmxterm retrieves MBean Attribute values in an interactive shell, whereas cmdline-jmxclient retrieves it non-iteractiavely.

The syntax of cmdline-jmxclient is as follows:

Z:\>java -jar cmdline-jmxclient-0.10.3.jar

Usage: java -jar cmdline-jmxclient.jar USER:PASS HOST:PORT [BEAN] [COMMAND] Options:

USER:PASS Username and password. Required. If none, pass '-'.

E.g. 'controlRole:secret'

HOST:PORT Hostname and port to connect to. Required. E.g. localhost:8081.

List registered beans if only USER:PASS and this argument.

• BEANNAME Optional target bean name. If present we list available operations and attributes.

• COMMAND Optional operation to run or attribute to fetch. If none supplied, all operations and attributes are listed. Attributes begin with a capital letter: e.g. 'Status' or 'Started'. Operations do not. Operations can take arguments by adding an '=' followed by comma-delimited params. Pass multiple attributes/operations to run more than one per invocation.
