OpsCenter release notes

OpsCenter release notes provide information about enhancements and changes in each release, as well as known issues.

For upgrade guidance, see upgrading OpsCenter.

For DSE version compatibility, see OpsCenter compatibility with DSE. DSE 5.1, 6.8, and 6.9 are supported by OpsCenter 6.8.39 and later.

Known issues in OpsCenter 6.8.0

The following are known issues that exist in OpsCenter 6.8.0, and they can persist into later versions if they aren’t resolved. Workarounds are provided if available.

This list might not be exhaustive or synchronized with the latest patch release. For the fixes and known issues in 6.8.4 and later, see the release notes for those versions in the DataStax release notes repository.

If you have any questions, contact DataStax Support.

  • (Fixed in 6.8.6) Data might not display on graph queries for graphs restored with OpsCenter. This occurs when using DSE 6.8.0 or later, the restored graph uses DataStax Graph Classic, and the restore doesn’t use sstableloader. If the graph is empty, use OpsCenter to perform a rolling restart of the cluster. After the restart, data should be visible with graph queries. (OPSC-16476)

  • When restoring materialized views, OpsCenter does not correctly wait for the cluster schema to settle, which can cause errors when data is restored to the table on which the view is based. (OPSC-13029)

  • If there are approximately 75 or more keyspaces, the DataStax Agent /tokenranges API call runs out of memory with the default heap size. As a temporary workaround, adjust the agent heap size. (OPSC-11975)

  • For DSE versions 5.1 and later, slow query data is only available since the last time the DataStax agent was restarted. (OPSC-11702)

  • Insufficient permissions on the staging directory can cause the agent to exhaust inotify watches on the system over time. (OPSC-10732)

  • Users will see an ungraceful error+stack trace in opscenterd.log if accessing a cluster through the UI/API that no longer exists. The error message contains “ERROR: Unhandled error in Deferred: There are no clusters with name or ID…​”. This error message is harmless. (OPSC-8819)

  • Lifecycle Manager is not currently compatible with DSE Transparent Data Encryption. See Encrypted DSE configuration values for more details. (OPSC-7529)

  • All DSE Graph properties in dse.yaml can be managed through the LCM UI with the exception of gremlin_server.serializers and gremlin_server.scriptEngines. If you need to customize the properties with LCM, you must use the LCM API to make changes.

  • When using LCM to configure credentials in a Repository, special characters such as # and $ are supported, but non-ascii unicode characters are not. (OPSC-8921)
