Install DataStax OpsCenter using APT repositories on Debian or Ubuntu distributions.

Install the DataStax OpsCenter on Mac OS X or any Linux Distribution using the OpsCenter binary tarball.

Instructions to uninstall OpsCenter for all installation methods: standalone, RPM, Debian, or tarball.

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

Security configuration options and instructions.

The OpsCenter Event Log page in the Activities section displays a continuously updated list of events and alerts.

OpsCenter collects system and table metrics data for each node in a cluster.

OpsCenter uses definition files to enable support for different versions of DataStax Enterprise, DataStax Community, and Cassandra without the need to upgrade the currently installed version of OpsCenter itself.

Automatic failover from the primary DataStax OpsCenter instance to the backup OpsCenter instance provides high availability without any manual intervention or downtime.

Enable route URL deep linking within the UI, which allows URL navigating to locations within the OpsCenter UI web application.

Configure capabilities by manually modifying the opscenterd.conf, cluster_name.conf, and address.yaml configuration files.

OpsCenter allows starting and stopping the DataStax Enterprise/Cassandra process on each node in a visual manner. Customize the startup or shutdown of a node using the provided example scripts.

Example scenarios of OpsCenter deployments include configuring for multiple regions, IP forwarding, or very large clusters.

Introduces the major areas of functionality available in the OpsCenter workspace.

Describes logging in and out of OpsCenter and changing the user password when authentication is enabled.

Provision a new Cassandra or DataStax Enterprise cluster locally or in the cloud using OpsCenter. Provision DataStax Enterprise clusters to multiple datacenters.

From the Nodes section of OpsCenter, select different views (Ring or List) of the nodes that comprise a Cassandra cluster and perform node management.

Manage keyspaces and the tables within keyspaces.

OpsCenter manages multiple DataStax Enterprise or Apache Cassandra clusters with a single install of the central opscenterd server. Administer your clusters using the options available from the Cluster Actions menu. Generate reports from the Help menu.

Monitor performance metrics in the OpsCenter Dashboard. Real-time and historical performance metrics are available at different granularities: cluster-wide, per node, or per table (column family).

DataStax Enterprise comes bundled with enterprise management services that you can configure and run using OpsCenter.

Increasing the nodelist polling period or setting a sleep delay can reduce excessive CPU usage when starting or running opscenterd.
