Monitoring events in CEM

Learn the options, available in the Edge Events screen, that enable you to monitor C2 server and agent events.

Click the Edge Events icon () to navigate to the Edge Events screen.
The Edge Events screen provides the following details for events:
  • Date/Time
  • Severity
  • Event Type
  • Message
  • Class Name
  • Source Type
  • Event Source ID

The Class Name and Event Source ID fields also act as links. If you click a class name link, the Metrics tab for that class appears and helps you to track details and alerts for that class, as described in the Monitoring deployments in CEM. If you click an event source ID link, the Metrics tab for that event appears and helps you to track details, alerts, commands, and configurations for that event, as described in the Managing agents in CEM.

You can display events based on time range (All, Last Hour, Last 4 Hours, Last 24 Hours, Last 7 Days) by selecting the desired value in the Time range drop-down. The number of rows displayed (20, 50, 100) can be configured by selecting the desired value from the Rows per page drop-down. The following image shows the Time range and Rows per page options in the UI:


Sorting and filtering

You can sort data in each column in ascending or descending order by clicking the column name. For example, you can sort the events based on class by clicking the Class Name column.

You can also filter the events by Date/Time, Severity, Event Type, Message, Class Name, Source Type, and Event Source ID. Select the column name in the drop-down box at the top-right corner of the UI, enter the filter value, and select RETURN on the keyboard to apply the filter.

You can use multiple column names and filter values to filter your data. Here is an example of filtering by Event Type and Source Type:


After you filter the event details as per your requirement, you can share the URL with other users who can then view your filtered event list.

Reload and show latest

You can view new events in the system by selecting either the Reload or Show Latest link which appears after you spend some time in the Edge Events page. Reload refreshes events using the existing search and sort criteria. Show Latest reloads events but sorts by the latest events using the existing search criteria.

The following image shows the Reload and Show Latest links in the Edge Events screen:

You can find the details of events by clicking the edge event details icon () beside each event. The following image shows event details of the event selected in the Edge Events section:
