Callimachus can be monitored using jconsole that is provided with a JDK install. The server certificate, created by the install script, must be trusted for jconsole to connect. This can be done by copying the etc/truststore from the server to the machine that will run jconsole. Run the following command, then provide the host name or IP, port 1090, username controlRole and password (found in etc/jmxremote.password) to the connection dialogue box.
jconsole -J-Djavax.net.ssl.trustStore=etc/truststore
