Use the Alerts panel
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:
- In the CMC navigation bar, select Alerts > Triggered Alerts.
- 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.
