Performance Service Overview
The OpsCenter Performance Service provides visual monitoring of diagnostics collected through the DSE Performance Service, displays alerts, and provides recommendations for optimizing cluster performance. The OpsCenter Performance Service combines OpsCenter metrics with CQL-based diagnostic tables populated by the DSE Performance Service to help understand, tune, and optimize cluster performance.
Performance Service overview panels

Table Metrics: Displays metrics to discover and diagnose poorly performing tables.
Thread Pool Statistics: Displays information about
Cassandrasystem-level details such as thread pools.

Any rules that fail send an alert to the relevant Alerts panel in each performance page, and generate suggestions to remediate issues in the Recommendations panels. The Best Practice Service monitors rules configured for the Performance Service Advisors:
By default, all rules are enabled and scheduled to run every hour. Adjust the rule configuration to suit the requirements of your environment.
