OpsCenter 5.1.1 Release Notes

Improvements

Support for connecting to a separate DSE storage cluster with SSL enabled. (OPSC-1336)
OpsCenter only stops the Repair Service based on real rather than estimated low throughput. (OPSC-2073)

Fixed error with restoring from the Backup Service in certain schemas. (OPSC-4587)
Agent no longer throws OutOfMemoryError when improperly trying to connect to a cluster that has authentication enabled. (OPSC-4699)
Workarounds to rectify prohibitively high CPU usage when opscenterd runs or starts up managing multiple clusters. (OPSC-4421)
Fixed rolling restart errors persisting in the UI by allowing users to dismiss the error. (OPSC-4023)

A bug in the Edit Cluster Settings dialog always sets Validate SSL Certificates to enabled (true), which can cause the connection to Cassaandra to fail if you are using a self-signed certificate. See the workaround for Troubleshooting SSL validation for self-signed certificates. (OPSC-4894)
Agents do not connect automatically if Cassandra is not listening on 127.0.0.1. If the rpc_address property in cassandra.yaml is configured to an IP address other than 127.0.0.1 (localhost) or 0.0.0.0, you must configure the hosts property in address.yaml for the agent on each node (e.g., hosts: ["55.200.55.200"]). (OPSC-4833)
