what it is ?

Result of experiments with UAA's mbeans, simple exporter of UAA's metrics to prometheus format. It include also parsed output from cloudfoundry.identity.ServerRequests.Globals (json data). Code quality is debatable, but it works (｡◕‿‿◕｡)

building

Just generate shadow jar

./gradlew clean shadowJar
java -jar -Xms32m -Xmx32m build/libs/uaa-prometheus-exporter-server-1.0-SNAPSHOT.jar

UAA requirements

UAA has to accept remote JMX connection, if you are using gradle to run UAA, please add following system env to your build

property 'com.sun.management.jmxremote.authenticate', System.getProperty('com.sun.management.jmxremote.authenticate', 'false')
property 'com.sun.management.jmxremote.port', System.getProperty('com.sun.management.jmxremote.port', '9876')
property 'com.sun.management.jmxremote.ssl', System.getProperty('com.sun.management.jmxremote.ssl', 'ssl')
