Managing DRA Operations

Operations Overview

The Operation page enables you to access various interfaces and perform operations, maintenance, and troubleshooting activities. It assists system administrators and network engineers to operate and monitor the Policy Server.

Monitoring DRA

DRA monitoring page under operations includes the following options:

  • DRA Peer Monitoring

  • DRA Binding Monitoring

  • DRA SLF Bindings

  • Grafana

Peer Monitoring

DRA peer monitoring page displays the active peer endpoints (by default) for the cluster node. You can click the toggle for active/inactive peers to view the active or inactive peer endpoints.

The active and inactive peer monitoring screens have resize option for each column. You can use the scrollbar to view multiple values.

You can use the filter option to filter active and inactive peer endpoints. You can also view all event logs and peer details for specific active or inactive peer endpoints of the cluster node.

Pagination support is provided in active and inactive peer endpoints table data. A number of rows per page drop-down is displayed below each table which contains the different set of numbers indicating the number of rows which can be shown per page. This option enables you to perform the following tasks:

  • Select the number of rows to be displayed in each page.

  • Specify the page to which you want to navigate.

You can use the Close All option to close all the displayed popups. By default the Close All option is disabled. If you have many popups open, the Close All option gets enabled.
