Install the DataStax OpsCenter using Yum repositories on RedHat Enterprise Linux (RHEL), CentOS, and Oracle Linux (OL) distributions.

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

Install DataStax OpsCenter on any Linux Distribution or Mac OS X 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.

Ports reference, instructions for starting and stopping OpsCenter and DataStax Agents, default file locations, and a startup log for OpsCenter.

Security configuration options and instructions.

Configure email alerts, post alerts to a URL, or enable SNMP traps for integrations with enterprise reporting systems.

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 without the need to upgrade the currently installed version of OpsCenter.

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

Back up critical configuration data for OpsCenter and Lifecycle Manager.

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

Configure sending metrics from OpsCenter to a Graphite server. This is an OpsCenter Labs feature in development.

Configure the JVM parameters for the OpsCenter JVM.

Configure the JVM parameters for the DataStax Agent JVM.

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

OpsCenter allows starting and stopping the DataStax Enterprise 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 or very large clusters.

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

From the Nodes section of OpsCenter, select different views (Ring or List) of the nodes that comprise a DataStax Enterprise cluster and perform node management. View the status of agents, install and upgrade agents, and troubleshoot any agent issues in the Agents view.

Manage keyspaces and the tables within keyspaces.

OpsCenter manages multiple DataStax Enterprise 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, per table (column family), or storage tier.

Describes the Backup Service, which allows you to automatically or manually backup and restore data in your clusters.

The Repair Service is configured to run continuously and perform repair operations across a DataStax Enterprise cluster in a minimally impactful way.

Using trend analysis and forecasting, the Capacity Service helps you understand cluster performance within its current environment and workload, and gain a better sense of how time affects those trends, both past and future.

The Best Practice service allows scheduling pre-defined best practice rules that check various properties of clusters and environments and report back which nodes pass or fail the rules.

The OpsCenter Performance Service combines OpsCenter metrics with CQL-based diagnostic tables populated by the DSE Performance Service to help understand, tune, and optimize cluster performance. Visually enable the performance objects and analyze the results within OpsCenter.

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

Troubleshooting tips for typical SSL issues.

Troubleshoot browser issues that can prevent the OpsCenter UI from loading properly. Review currently supported browsers.

Rectify issues encountered surrounding SSTables.

Adjust configuration settings to manage and display metrics.

For OpsCenter versions prior to 3.2.1, truncate tables to reclaim space.

Upgrade Python if you encounter any difficulty adding a keyspace in OpsCenter prior to version 5.2.

Ensure there are no conflicts with port 7199 used by the DataStax Agent.

Error when Java is not installed or the path is not set.

Refer to the recommended settings for insufficient user resource limits errors in the Cassandra documentation.

An introduction to Lifecycle Manager (LCM) for provisioning DataStax Enterprise (DSE) clusters and centrally managing configurations. Simplify deploying and configuring DataStax Enterprise clusters with Lifecycle Manager.

Create and manage the DataStax Enterprise cluster topology model in the Clusters workspace of Lifecycle Manager. Run install and configure jobs at the cluster, datacenter, or node level.

View a summary and drill into details of install, configure, and import jobs in Lifecycle Manager. Monitor the progress of running jobs. Troubleshoot failed and abort idle jobs.

Repositories use predefined credentials for automatically downloading Debian or RPM packages from the DataStax Enterprise repository or from a private repository that is an internal mirror of the DataStax repository.

SSH credentials allow securely connecting to machines without repeatedly entering credentials for each DataStax Enterprise install, configure, or import job. Define SSH credentials for cluster, datacenter, or node levels.

Define centrally-managed configuration profiles to enforce uniform configuration at the cluster, datacenter, or node level.
