Working with event subscriptions in the client

The event subscriptions summary page displays the type of subscription (Target), where the events are being sent (Event URL), the subscription status (Enabled or Disabled), and when the last event was sent (Last Event).

From here, you can:

•

View existing subscription details.

•

Add ArcSight, Splunk, QRadar, IT Security Search, and Syslog subscriptions.

•

Edit ArcSight, Splunk, QRadar, IT Security Search, and Syslog subscriptions.

•

Create a QRadar extension.

•

•

Enable and disable a subscription.

See Managing a Splunk integration, Managing an IBM QRadar integration, Managing a Micro Focus Security ArcSight Logger and Enterprise Security Manager (ESM) integration, Managing a Quest IT Security Search integration (Preview), and Managing a Syslog integration for details.

Managing a Splunk integration

Managing a Splunk integration

To begin to take advantage of the rich data gathered by Change Auditor by sending event data to Splunk, you need to create an event subscription with Change Auditor. The subscription contains information about where to send the notifications and heartbeats and the event subsystems to include.


	NOTE: Columns that do not contain any event data will not display in Splunk.

IMPORTANT: To configure Splunk to receive events from Change Auditor you need to configure an HTTP event collector token in your Splunk instance.

1

Within Splunk, navigate to Settings | Data Inputs | HTTP Event Collector. Ensure that All Tokens are enabled under the Global Settings.

2

Click New Token and complete the steps in the wizard.

3

Copy the token. This value is required to create a Splunk subscription in Change Auditor.

Currently, you can create and manage a subscription for managed and unmanaged Splunk Cloud and Splunk Enterprise editions through the Change Auditor client or through PowerShell commands.
