The event structure is the primary data structure used by all components of the Event Logging feature and consists of the following attributes. The table also shows how the event structure is represented in the Apache Camel Exchange structure (header and body attributes).

Attribute Name Type Camel Exchange Mapping Description
eventUUID String header.eventuuid Unique ID associated with every event.
category String header.category

Each event can be assigned to a particular category. Category will help to group and organize events which can be further searched and filtered.

default, audit and ping are reserved categories and cannot be used as category names.

Categories that can be used to begin with might be system, osgi, service, route, bam, sam and security. But the user can easily define and use additional categories. New category names should comply the following: A-Z, a-z, 0-9 and ‘_' characters are supported, and only maximum 32 characters are allowed.

eventtype String header.eventtype

Attribute to identify the listener from which this event was captured. Pax listener for LOG Event, OSGI Listener for OSGI Event, and SAML Listener for SAM Event.

logmessage String body The log message associated with this event.
severity String header.severity Describes the severity of the event. For example, the log4j log levels.
logsource Map header.source

The logsource is collection of data which identifies the source of the generated event. For example :

 "bundle.id": "124",
 "bundle.version": "2.7.7",
 "class.name": "org.apache.cxf.manage
 "host.name": "sopera",
 "line.number": "329",
 "logger.name": "org.apache.cxf.manag
 "process.id": "6468"
agenttimestamp Date header.agenttimestamp

The Timestamp applied on the event when the Event Logging Agent receives it.

The timestamp is the date and time of the local machine, converted to UTC date / time with milliseconds and the local timezone of the machine. For example: 2013-07-23T08:45:30.453Z

servertimestamp Date header.servertimestamp The Timestamp applied on the event when the Event Logging Collector Service receives it. The timestamp is the date and time of the server machine, converted to UTC date / time with milliseconds and the timezone of the server. For example: 2013-07-23T08:45:30.453Z
logtimestamp Date header.logtimestamp The Timestamp of the log when it was created. The format of the timestamp depends completely on the logging framework. It will not be converted or transformed by the agent. If no timestamp exists in the log, this attribute will be empty.
audit boolean header.audit A flag to indicate if the event needs to be audited. The default value of this attribute is false.
agentid String header.agendid The local agent ID which handled this event. Every agent should have a unique agent ID.
auditsequenceno long header.auditsequenceno The sequence number is continuously incrementing by +1 on the agent for each new Audit Event, and only for Audit events. This prevents audit events from being repeated later in the EventLogging Database.
signedlogmessage String header.signedlogmessage The log message in XML format including the signature information.
correlationid String header.correlationid An ID used to correlate different events: the Business Correlation ID. In case of SAM Event, the technical FlowID will be stored as eventlog_custominfo key / value.
subject String header.subject The User which created this event.
custominfo Map header.custominfo It is a collection of key / value pairs. This attribute can be used to propagate custom information. For example:
 "activemq.broker": "eventloggingbrok
