The Cassandra Database Integration provides seamless access to performance metrics and enables users to effortlessly visualize crucial insights in a single dashboard. The integration works by pulling metrics from the database through the Middleware Host Agent.

This integration is only supported for users with the default AllowAllAuthenticator authentication permissions.

Prerequisites

Middleware Host Agent (MW Agent) must be installed on your local machine. To install the MW Agent, see our Installation Guide.

Setup

Step 1: Access Integrations

Login to your Middleware account, navigate to the Installations page in the bottom left corner, select All Integrations and click Cassandra

Step 2: Connect Cassandra Instance

To access Cassandra metrics, choose a host to connect to your Cassandra Cluster

Hosts will only show up in this list if they have a running Host Agent

Step 3: Configure Your Host

Configure your host to connect to the IP address and JMX port of Cassandra Cluster

The default port for your Cassandra instance is 7199
