endprologue.

Programmatic Access

By using the Neo4j.management method you can get information about a running neo4j instance.

Example:

Neo4j.management.get_number_of_node_ids_in_use
Neo4j.management.getNumberOfPropertyIdsInUse
Neo4j.management.getNumberOfRelationshipIdsInUse
Neo4j.management.get_number_of_relationship_type_ids_in_use

# Example Neo4j HA Cluster Info
Neo4j.management(org.neo4j.management.HighAvailability).isMaster

The following monitoring classes are available, http://api.neo4j.org/current/org/neo4j/management/package-summary.html

Using the JConsole

You can remotely access information of a running db instance or a cluster using the
jconsole java tool, check Monitoring_and_Deployment
and operations-monitoring

Using neo4j-shell

The neo4j.rb gem comes included with the neo4j-shell bin script.
To get remote access to a running neo4j instance you must enable the configuration

Remote access is only available if the configuraiton property enable_remote_shell is defined.
It is defined by default to port=9332

Example, to configure the port.

Neo4j::Config['enable_remote_shell'] = "port=9999"
#

To run the neo4j shell program:
neo4j-shell -port 9332
