OpsCenter offers a number of features to help manage both DataStax Enterprise and Apache Cassandra clusters and make your life easier.

DataStax agents must be installed on every managed node in a cluster and are necessary to perform most of the functionality within OpsCenter.

A list of the default port numbers used by OpsCenter and the DataStax Agents:

By default, access control is disabled. Any user that knows the OpsCenter URL can view all objects and perform all tasks. To control access, you configure authentication for OpsCenter users by performing these tasks:

OpsCenter uses Secure Socket Layer (SSL) to encrypt the communication protocol and authenticate traffic between DataStax agents and the main OpsCenter daemon.

You can enable or disable Hypertext Transfer Protocol Secure (HTTPS) support in OpsCenter.

The OpsCenter Event Log page displays a continuously updated list of events and alerts.

OpsCenter collects system and column family metrics data for each node in your cluster.

To configure advanced capabilities, you can manually modify the configuration files.

This task describes how to manually backup the configuration files of opscenterd in case of a failure of the primary opscenterd instance.

OpsCenter allows users to start and stop the DataStax Enterprise/Cassandra process on each node in a visual way. The agent will attempt to automatically determine the best way to do this, but cannot not do so in all cases. You can customize the startup or shutdown of a node using the start-cassandra and stop-cassandra scripts located in /usr/share/datastax-agent/bin (package installs) or <install_location>/bin (tarball installs).

The major areas of functionality.

In the Cluster section of OpsCenter, you select different views of the nodes comprising your Cassandra cluster and then perform node management.

OpsCenter manages multiple DataStax Enterprise or Apache Cassandra clusters with a single install of the central opscenterd server.

In the Performance area of OpsCenter, you monitor a number of performance metrics about a Cassandra cluster. Real-time and historical performance metrics are available at different granularities: cluster-wide, per node, or per column family.

From the Alerts area of OpsCenter Enterprise Edition, you can configure alert thresholds for a number of Cassandra cluster-wide, column family, and operating system metrics. This proactive monitoring feature is available only in OpsCenter Enterprise Edition.

DSE comes with some enterprise management services which you can configure and run using OpsCenter.

Using OpsCenter Enterprise Edition, you can take, schedule, and manage backups across all registered clusters.
