Events/Logs Schema

When events are sent from open-appsec agents to be viewed in the cloud application and/or to a Syslog/CEF server, they are sent in a specific field structure.
This page will document the fields being sent. This will allow filter queries in the cloud application and log parsing to be done on the Syslog/CEF side (see configuration of Trigger objects for more info).
Schema in openAPI format

The definitions per field are relevant even when the logs aren't sent in JSON format.
Log fields
This table shows the predefined field keywords alongside their view name in the logs table and log cards.
in brackets for each field name is the name when sent to syslog/CEF. Usually the difference is simply an all-lowercase format vs lowerCamelCase
Field Name in Log View
Field Name

This field describes the event in text.
Severity
eventseverity (eventSeverity)
Info, Low, Medium, High, Critical
Priority
eventpriority (eventPriority)

Some events result in showing the user a reference ID (for example when showing an HTTP response page upon prevention). This reference ID will correlate to this field in the log.
Agent UUID
agentid
(agentId)
UUID of the agent creating the log, if applicable.

HTTP Request Body
httprequestbody
(httpRequestBody)
HTTP Request Body (Sent only if relevant additional logging is configured on the trigger object that was used). Body will be truncated if too long.
AppSec Incident Type
waapincidenttype
(waapIncidentType)
