Use the Alerts dashboard

CMC provides preconfigured platform alerts for missing forwarders and skipped searches that you can enable. You can also create custom platform alerts using the global Searches, Reports, and Alerts page accessible through the CMC Alerts functionality.

When a CMC platform alert is triggered, a message alert displays on registered mobile devices that are equipped with a Splunk Mobile app for Splunk Cloud Platform administrators. The alert does not display in Messages in the top Splunk Cloud bar in Splunk Web.

Splunk Cloud Platform administrators can also review alerts on the Triggered Alerts page of the CMC app and the Alerts count column on the Searches, Reports, and Alerts page.

You must be on at least app version 2.1.1 to use the CMC platform alerts functionality. To check the app version, select Support & Services > About. The CURRENT APPLICATION area at the bottom of the About page shows the app's version and build numbers.

Review triggered alerts

To view triggered alerts:

1. In the CMC navigation bar, select Alerts > Triggered Alerts.
2. The page displays the name of any triggered alert and a timestamp of when it was triggered.

When a preconfigured alert is triggered, CMC displays an alert with a 3 severity level on the Triggered Alerts page, which indicates medium severity.

Starting with CMC 2.6.0, preconfigured alerts use the prefix CMC. Alerts with the prefix SIM are retained for backwards compatibility.

The table describes the situations that trigger a preconfigured alert and the CMC dashboards to review to take further action.

Review preconfigured alerts

In the CMC navigation bar, select Alerts > Configured Alerts. The table displays the preconfigured CMC alerts and any custom alerts that you or another Splunk Cloud Platform administrator configured for your organization's deployment. Last Updated shows when an alert was edited.

Select the Enabled toggle to enable or disable an alert.

Select the Mobile Alert toggle to enable or disable an alert on mobile devices. Enabling an alert automatically enables it for display for Splunk Cloud Platform administrators on Splunk Web and registered mobile devices equipped with a Splunk Mobile app. For more information on downloading and registering a Splunk Mobile app, see the following:

• Download Splunk Mobile for iOS
• Download Splunk Mobile for Android
• Log in to a Splunk platform instance in a Connected Experiences app

Select Edit to access the Searches, Reports, and Alerts page. You can view detailed information about an alert and perform specific actions, such as reviewing the alert definition and running the alert.

Do not edit the search field for preconfigured alerts.

Manage CMC Alerts on the Searches, Reports, and Alerts page

To manage CMC platform alerts on the Searches, Reports, and Alerts page, follow these steps:

1. Access this page through one of the following methods:
• Select the Edit link adjacent to an alert on the Alerts > Configured Alerts page in the CMC app.
• In the Splunk Cloud bar at the top of the page, select Settings. In the KNOWLEDGE section, select Searches, reports, and alerts.
2. Set Type to Alerts.
3. Set App to Cloud Monitoring Console (splunk_instance_monitoring).
4. Set Owner to All or Nobody. The CMC and SIM alerts for CMC appear.
5. In the Actions column, select Edit > Enable.

Create custom alerts

You can also create custom platform alerts using the Searches, Reports, and Alerts page. You can access this page through one of the two methods noted in step one of Manage CMC Alerts on the Searches, reports, and alerts page. Select the New Alert button to define an alert and the corresponding action to be performed when the alert is triggered. For example, you can send an email to the email account in a Splunk Cloud Platform administrator's profile, or an alert to their registered mobile device equipped with a Splunk Mobile app.

For more information, see the following:

• Set up alert actions in the Alerting Manual
• The global Alert Actions page. To access this page, in the Splunk Cloud bar at the top of the page, select Settings. In the KNOWLEDGE section, select Alert actions.
