# Monitoring and management

You can monitor and manage Liberator at run time in several ways:

* Through [JMX](https://www.oracle.com/java/technologies/javase/javamanagement.html) monitoring, using a JMX-enabled client, such as the [Caplin Management Console](../cmc/index.md).
* By directly viewing or extracting the contents of log files (see [Logging](liberator-logging.md)).
* Through the [Liberator status web page](liberator-liberator-status-web-page.md) and [Liberator Explorer](liberator-liberator-explorer.md).

  **📌 NOTE**\
  The Liberator status web page and Liberator Explorer are only intended for development environments, as they aren’t secure enough to use in production systems. A JMX monitoring client application can be designed so that it logs in to the Liberator securely through [Caplin KeyMaster](../keymaster/index.md), and this would make such a monitoring client suitable for production systems.

## JMX Monitoring

Liberator is supplied with a built-in Liberator JMX [Config blade](liberator-configuration-and-blades.md) that you can activate to make it send status data across to JMX clients, such as to the [Caplin Management Console](../cmc/index.md). The standard DataSource monitored items are available (see [DataSource monitoring and management](../datasource/datasource-datasource-monitoring-and-management.md)), plus the following Liberator specific items:

* System data: aggregated information about the total number of sessions, objects subscribed to, and data throughput, plus information about any configured clusters.
* User data: information about all connected users and their sessions, including latency and object subscription details. You can also eject and revalidate users, and cancel subscriptions.
* Object data: details of all objects in the system: their type, stale status, update times, subscription counts, and which sessions are viewing each object.
* Licence status and licence related messages.
