Common Event Format (PD-CEF)

Overview of the PagerDuty Common Event Format that is used to correlate similar items across integrations

The PagerDuty Common Event Format (PD-CEF) is a standardized alert format that allows PagerDuty to correlate similar items across integrations and better understand the events from your environment. PD-CEF also allows you to view alert and incident data in a cleaner, more normalized way. You can also use PD-CEF to dynamically suppress non-actionable alerts with Event Orchestration.

PD-CEF details display at the top of alert and incident detail pages. They express common event concepts in a normalized, readable way.

PD-CEF Fields

The table below outlines the name, type and description of each PD-CEF field, as well as an example value for each.

NameTypeExample ValueUsage
SummaryString"PING OK - Packet loss = 0%, RTA = 1.41 ms"w
"Host 'acme-andromeda-sv1-c40 ::' is DOWN"

Timestamp Timestamp2015-07-17T08:42:58.315+0000When the upstream system detected / created the event. This is useful if a system batches or holds events before sending them to PagerDuty.

A cluster or grouping of sources. For example, sources “prod-datapipe-02” and “prod-datapipe-03” might both be part of “prod-datapipe”

The alerts table highlights PD-CEF fields in your alerts: Severity, Summary, Source, Class, Component, and Group. To customize the fields shown on the Alerts table, navigate to Incidents Alerts and click Customize Columns on the right side.

Events API v2

The Events API v2 offers an easier way to leverage PD-CEF fields in your alerts. Monitoring partners can now directly send events in the PD-CEF format, giving you the benefit of the format without the need to manually convert your events. Custom monitoring can also leverage this format, to take advantage of the PD-CEF display and workflow features in PagerDuty.

Review our developer docs for more information about the Events API v2 and how to use it.
