For information about new features and resolved issues in the following releases, see:
Before upgrading, check the compatibility of the OpsCenter version you want to run against your version of Cassandra or DataStax Enterprise.
- Fixed an issue with opscenterd not starting up when certain types of CQL3 column families exist.
- Column families created via CQL3 are recognized and monitored.
- Added support for provisioning nodes with vnodes enabled.
- Fixed OpsCenter not running without the proper SSL library being installed, even if SSL feature has been disabled, has been fixed.
- Fixed an issue with editing keyspace properties if another keyspace was recently updated.
- Fixed loading Performance presets with special characters in the name.
- Fixed agent hitting out of memory exception when cleaning up some backups.
- Fixed the List View rendering when nodes have long hostnames.
- Fixed an issue with adding nodes to an existing DSE cluster when some nodes were down.
- Fixed an issue when provisioning nodes using RackInferringSnitch and hostnames.
OpsCenter Enterprise Edition 3.0.2 changes include the following bug fixes:
- When adding internal Cassandra authentication to a cluster, the cluster's edited configuration can now be saved. Previoiusly an error was reported: Unable to connect to cluster.
- Scrolling long lists of column families in the Schema and Data Explorer panes has been implemented.
- Agents now receive configuration changes without having to be restarted.
- Compaction status now displays properly in List View or node popup.
- OpsCenter no longer becomes unresponsive (caused by an agent hanging) if there are too many files in the snapshots directory.
OpsCenter Enterprise Edition 3.0 supports Cassandra 1.2 when virtual nodes are disabled.
- Visual cluster creation and management
- Managing settings
- Restarting a cluster
- Database restore
- Customizable backups
- Software update notifications
- Improved object creation and management
- Automated collection of diagnostic data
- Offloading of metadata repository to secondary clusters
- DSE security and encryption
- Fixed node popup in Ring/Physical view going blank.
- Fixed agent data collection being interrupted on error.
- Fixed display of some data in Performance section.
- Fixed list of nodes in List View jumping around when compactions are running.
- Fixed several minor issues in the UI.
- Fixed several issues with installing opscenterd and the agents.
OpsCenter Enterprise Edition 2.1.3 supports Cassandra 1.2 when virtual nodes are disabled. This Edition also includes bug fixes.
OpsCenter Enterprise Edition 2.1.3 can monitor and administer Cassandra 1.2 as described in the documentation unless you enable virtual nodes. When you enable virtual nodes, OpsCenter chooses a single token for each node for operations such as collecting metrics. Attempting to move nodes, rebalance nodes, and perform other tasks involving token ranges is not supported.
- Fixed issue processing keyspaces that only exist in 1 datacenter.
- Fixed data collection issues during compactions on secondary indexes.
OpsCenter Enterprise Edition 2.1.2 changes include a new feature and bug fixes.
- Better parsing of some device types when collecting metrics.
- Fixed ability to configure user access on tarball installations.
- Fixed Cluster Report feature on tarball installations.
OpsCenter Enterprise Edition 2.1 key enhancements include data modeling and data browsing, report generation, and additional metrics for performance monitoring.
- Browsing data in the Cassandra database.
- Generation of a PDF report about the cluster.
- Capability to handle thousands of column families efficiently.
- Online feedback form.
- Optional HTTPS support.
- Installation of agents to RHEL and Debian clusters regardless of the location of the configuration file (opscenterd.conf).
- Truncation of column families. Truncation removes the data but not the column family itself.
OpsCenter Enterprise Edition 2.0 is a major release that introduces backup and cluster enhancements.
- Multi-cluster management. You can manage multiple cluster from the same OpsCenter instance.
- New Overview page for monitoring multiple clusters. It shows a condensed view of each cluster's Dashboard. It is visible only when multiple clusters exist.
- Perform and schedule operations from OpsCenter.
- Point OpsCenter at existing Cassandra clusters, where you can add, modify, or delete clusters from OpsCenter.
- Adds support and metrics for DataStax Enterprise 2.0 Search nodes.
- No longer compatible with Cassandra 0.7.
- Fixed opscenter-agent package not starting on machine restart.
- Allow node move operation when a keyspace is set to replicate to a non-existent data center.
- Fixed agent listen address when SSL is disabled.
- Fixed data explorer error when searching for row key containing "#".
