Configuring Remote JMX monitoring

In order to enable JMX Remote monitoring, edit the neo4j-wrapper.conf file in Neo4j 3.0.x versions or neo4j.conf file in Neo4j 3.1.x versions and uncomment the following lines:

dbms.jvm.additional=-Dcom.sun.management.jmxremote.port=3637
dbms.jvm.additional=-Dcom.sun.management.jmxremote.authenticate=true
dbms.jvm.additional=-Dcom.sun.management.jmxremote.password.file=conf/jmx.password
dbms.jvm.additional=-Dcom.sun.management.jmxremote.access.file=conf/jmx.access

After uncommenting the above lines, restart neo4j. If the neo4j process does not start, look in the logs/neo4j.log file and look for errors.

If you see one of the following errors:

Error: Password file not found: conf/jmx.password

or

Error: Access file not found: conf/jmx.access

It means neo4j it is unable to locate the jmx.password and/or jmx.access files. In order to fix this issue, one will need to specify the complete path for those files as shown below:

dbms.jvm.additional=-Dcom.sun.management.jmxremote.password.file=$NEO4J_HOME/conf/jmx.password
dbms.jvm.additional=-Dcom.sun.management.jmxremote.access.file=$NEO4J_HOME/conf/jmx.access

After making the above changes restart neo4j and verify that the database comes online. ”’
