What’s new in OpsCenter 1.3
Since releasing OpsCenter 1.0, we have done a lot of work focusing on stability and performance -- particularly when dealing with large clusters. After the release of OpsCenter 1.2.3 in August, we felt that the product was in a really good place, and were able to focus on some big improvements and critical features users have been asking for.
With OpsCenter 1.3 we are introducing two editions: OpsCenter Community and OpsCenter Enterprise. In both editions, we've added a Help section inside of the web UI to guide users through new features and answer commonly asked questions. We've also made some changes in architecture to significantly reduce the number of open ports required between the central OpsCenter machine and each of your nodes, which makes it easier to keep your infrastructure secure. In Opscenter Enterprise, we are pleased to announce two new features to make administrators lives easier: Cluster Rebalancing and Proactive Alerts.
While Cassandra's architecture makes adding nodes to a cluster very simple, managing tokens to ensure nodes are distributed around the ring evenly can be anything but. Unless a user is willing to double the size of the cluster -- which you can imagine is neither ideal, nor typically feasible -- manual token calculations must be made, as well as manually moving all of the nodes in the cluster to their ideal positions.
In OpsCenter 1.3, we've taken this process and made it extremely easy. After adding your nodes anywhere in the ring, simply click the "Rebalance Cluster" button and OpsCenter will do all of the work for you in the most efficient way possible. OpsCenter will handle all node moves and cleanup tasks for you in the background, which takes all of that burden off your shoulders.
OpsCenter has always collected a lot of data about the performance and health of your cluster. However, the only way users were able to utilize this data was by viewing historical graphs. With OpsCenter 1.3, users can now setup proactive alert rules and be notified when significant events happen.
Some examples include being notified when a node goes down, or when disk utilization grows over a certain amount. Combined with our event push system, these rules can be used to send email notifications or post the data to a configurable URL -- which allows you to integrate alerts into other systems you may be using. Again, all of this happens in the background, allowing you to receive alerts without having the OpsCenter web UI open.
In addition to these two great features, we've also made several improvements to our UI and to the overall stability of the product. We're very excited about what's in store for the future. If you have any feedback or suggestions you'd like to make, please don't hesitate to visit our forums.
