What's New in OpsCenter 2.0: Multiple Cluster Support
In previous versions of OpsCenter, each installation was limited to managing a single Cassandra or DataStax Enterprise cluster. For many people, this meant deploying OpsCenter multiple times in order to manage their dev and production clusters, or even their many production clusters. This was less than ideal for many of our customers, so we are happy to announce support for managing multiple clusters in the Enterprise release of OpsCenter 2.0. You can download OpsCenter Enterprise edition for non-production use and test out the new multiple cluster support after registering here.
An additional benefit of multiple cluster support is that the initial configuration of your OpsCenter install is now much easier. First, you will want to download and install OpsCenter for your specific system. After downloading and installing OpsCenter, generally the only thing you will need to configure is the web server interface. The default is 127.0.0.1, but you can configure it for your system. Once you configure the interface and start the OpsCenter process, you will be asked to configure your first cluster by specifying the IP addresses of some of your cassandra nodes as well as the ports your cluster is configured to use (specifying the ports is unnecessary unless you changed the defaults).
Managing Multiple Clusters
When using OpsCenter 2.0 with a single cluster you won’t notice many differences in the web interface that you are used to from previous versions. You will, however, notice a new action in the top right corner of the OpsCenter interface. Clicking will bring up the same popup that was presented for the initial cluster configuration and allow you to add the appropriate information for a second cluster.
Once you have multiple clusters configured, you will notice an entirely new section of the OpsCenter interface. As part of multiple cluster support, OpsCenter includes a global dashboard for quickly checking the status of all of your clusters at a glance. From here you can view a global list of alerts across all of your clusters, as well as an individual status indicator for each cluster. This allows you to quickly see the storage capacity of a cluster, the status of the agents for each cluster, and a quick look at the important metrics for each cluster.
That wraps up a brief overview of the new multiple cluster support in OpsCenter 2.0. We always appreciate feedback, so feel free to post any you have in the comments. You can also post any feedback or issues you have with multiple cluster support in the support forums. Stay tuned for more info on the new features in OpsCenter 2.0.
