Starting, Stopping and Monitoring

NOTE: This document is for information on starting an Apache Brooklyn Server. For information on using the Brooklyn Client CLI to access an already running Brooklyn Server, refer to Client CLI Reference.

Packages for RHEL/CentOS and Ubuntu

If you are using the .rpm or .deb package of Apache Brooklyn, then Brooklyn will integrate with your OS service management. Commands such as service brooklyn start will work as expected, and Brooklyn's PID file will be stored in the normal location for your OS, such as /var/run/

Platform-independent distributions

The platform-independent distributions are packaged in .tar.gz and .zip files.


To launch Brooklyn, from the directory where Brooklyn is unpacked, run:

% bin/start

With no configuration, this will launch the Brooklyn web console and REST API on http://localhost:8081/, listening on all network interfaces. No credentials are required by default. It is strongly recommended to configure security.

See the Server CLI Reference for more information about the Brooklyn server process.


To stop Brooklyn, from the directory where Brooklyn is unpacked, run:

For example:

% bin/stop


For .tar.gz and .zip distributions of Brooklyn, the Brooklyn startup script will create a file name pid_java at the root of the Brooklyn directory, which contains the PID of the last Brooklyn process to be started. You can examine this file to discover the PID, and then test that the process is still running. .rpm and .deb distributions of Brooklyn will use the normal mechanism that your OS uses, such as writing to /var/run/

This should lead to a fairly straightforward integration with many monitoring tools - the monitoring tool can discover the expected PID, and can execute the start or stop commands shown above as necessary.

For example, here is a fragment of a monitrc file as used by Monit, for a Brooklyn .tar.gz distribution unpacked and installed at /opt/apache-brooklyn:

check process apachebrooklyn with pidfile /opt/apache-brooklyn/pid_java
    start program = "/bin/bash -c '/opt/apache-brooklyn/bin/brooklyn launch --persist auto & disown'" with timeout 10 seconds
    stop  program = "/bin/bash -c 'kill $( cat /opt/apache-brooklyn/pid_java )'"

In addition to monitoring the Brooklyn process itself, you will almost certainly want to monitor resource usage of Brooklyn. In particular, please see the Requirements section for a discussion on Brooklyn's disk space requirements.
