Managing a Cluster
This topic describes the actions you can initiate from the Cluster Management screen, which include:
- Viewing the cluster’s CPU, Disk, and Memory Usage
- Reconfiguring cluster access
- Resizing your cluster
- Deleting your cluster
- Using Zeppelin and the Database Console with your cluster
The Cluster Management Screen
You can access the Cluster Management screen for any cluster in your Dashboard by simply clicking the name of the cluster.
This screen displays information about the cluster, and includes three panels that display a graph of resource usage over time. There are three similar resource usage graphs displayed:
- CPU Percentage Used (shown in the following image)
- Disk Usage
- Memory Usage
Modifying Your Cluster
Reconfiguring Your Cluster
To reconfigure your cluster, click the Reconfigure button; the cluster reconfiguration screen displays:
You can modify your VPC and/or IAM configuration information in this screen. Once you’ve entered your new information, click the Reconfigure button to update your configuration and return to your Cluster Management screen.
Resizing Your Cluster
To resize your cluster, click the Resize button. The Resize Cluster screen, which is pretty much identical to the Create New Cluster screen, displays:
You can adjust your cluster parameters, then click the Resize button, which will return you to your Cluster Management screen, where you’ll see the status of your cluster set to Updating.
Deleting Your Cluster
To delete your cluster, click the Delete button. You’ll be ask to confirm the deletion:
After confirming that you want to do so, your cluster will be deleted, and its status in your dashboard will show as Deleted.
Working With Your Database
Your dashboard includes buttons with which you can access two different means of working with your database; you can launch the DB Console or the Apache Zeppelin Notebook interface by clicking one of the buttons near the upper-right corner of the Dashboard screen:
Click the DB Console button to land on our Database Console interface.
Click the Notebook button to land on our Zeppelin Notebook interface.
Connecting to Your Database with JDBC
At the very bottom of the Cluster Management screen, below the three graph panels, is the URL you can use for a JDBC connection with your database service:
The same JDBC link was emailed to you in the message from Splice Machine letting you know that your cluster creation was successful.
