Management in Mass with OpsCenter 4.0

By Mike Bulman -  November 19, 2013 | 0 Comments

DataStax OpsCenter has always allowed users to run common operations such as cleanup and repair on individual nodes. It also has the ability to run certain operations across the entire cluster, such as configure and restart. With the new management-in-mass feature in OpsCenter 4.0, you can now run any operation on multiple nodes in your DataStax Enterprise cluster with a single click.

Gone are the days of writing scripts yourself or manually babysitting operations across multiple nodes.

How it Works

From the redesigned List View, select the checkboxes for your desired nodes, press the button for the corresponding operation, and let OpsCenter handle the rest.

To quickly run an operation across all nodes in a data center, sort by the DATACENTER column, check the first node in the data center, and hold shift while checking the last node in the datacenter.

OpsCenter will run the operation across nodes in a rolling fashion, which means it will not start the operation on the next node in the list until the previous node completes successfully. If the operation fails on a node in the list, the entire process will be cancelled, and the operation will not be started on any other nodes.

Notifications will appear at the top of the OpsCenter web interface to notify you when operations have started and completed:

REST API

As with all functionality, bulk operations can be directly via the OpsCenter REST API as well, to allow integrating with any other systems you may use. We’re still in the process of getting the API and documentation finalized, but feel free to leave a comment here if you’d like more information on that sooner than later.
