The OpsCenter features
OpsCenter is a superset of
nodetool
. It provides all the functionality of
nodetool
, dis-
plays metrics in an intuitive way, and provides administrative tooling beyond the default
toolset that comes with Cassandra. The following is a short list of features:
•
Centralized view of all the clusters
: A centralized view provides options to visu-
alize clusters in different modes: ring view, list view, and view by data centers.
•
Manage cluster configuration
: OpsCenter enables one to edit and update cluster-
wide configuration from the web console.
•
Visualize performance
: OpsCenter actually stores the performance history over
time. This can help you visualize performance in various time windows: 20
minutes, hourly, daily, weekly, and monthly.
•
Add a new node
: On your local cluster, you can ask OpsCenter to add another
node by providing the node address and credentials (of a sudoer), and choosing the
appropriate DataStax package, which is basically Cassandra and OpsCenter pack-
aged in a user-friendly way by DataStax.
OpsCenter's enterprise edition has the following features that are more advanced:
• New cluster addition from GUI
• Downloadable diagnostic information
• Single-click cluster rebalancing
• Multiple cluster management
• Alerts and e-mail notifications
Note
If you are on AWS EC2, OpsCenter allows you to automatically add a new node to your
existing cluster. This node is basically an instance of DataStax AMI with the appropriate
Cassandra version that you have chosen.
