Event Fields
editEvent Fields
editThe event fields are used for context information about the log or metric event itself.
A log is defined as an event containing details of something that happened. Log events must include the time at which the thing happened. Examples of log events include a process starting on a host, a network packet being sent from a source to a destination, or a network connection between a client and a server being initiated or closed. A metric is defined as an event containing one or more numerical or categorical measurements and the time at which the measurement was taken. Examples of metric events include memory pressure measured on a host, or vulnerabilities measured on a scanned host.
Event Field Details
editField | Description | Level |
---|---|---|
event.action |
The action captured by the event. This describes the information in the event. It is more specific than type: keyword example: |
core |
event.category |
Event category. This contains high-level information about the contents of the event. It is more generic than type: keyword example: |
core |
event.created |
event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent’s or pipeline’s ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. type: date |
core |
event.dataset |
Name of the dataset. The concept of a type: keyword example: |
core |
event.duration |
Duration of the event in nanoseconds. If event.start and event.end are known this value should be the difference between the end and start time. type: long |
core |
event.end |
event.end contains the date when the event ended or when the activity was last observed. type: date |
extended |
event.hash |
Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity. type: keyword example: |
extended |
event.id |
Unique ID to describe the event. type: keyword example: |
core |
event.kind |
The kind of the event. This gives information about what type of information the event contains, without being specific to the contents of the event. Examples are type: keyword example: |
extended |
event.module |
Name of the module this data is coming from. This information is coming from the modules used in Beats or Logstash. type: keyword example: |
core |
event.original |
Raw text message of entire event. Used to demonstrate log integrity. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from type: keyword example: |
core |
event.outcome |
The outcome of the event. If the event describes an action, this fields contains the outcome of that action. Examples outcomes are type: keyword example: |
extended |
event.risk_score |
Risk score or priority of the event (e.g. security solutions). Use your system’s original value here. type: float |
core |
event.risk_score_norm |
Normalized risk score or priority of the event, on a scale of 0 to 100. This is mainly useful if you use more than one system that assigns risk scores, and you want to see a normalized value across all systems. type: float |
extended |
event.severity |
Severity describes the original severity of the event. What the different severity values mean can very different between use cases. It’s up to the implementer to make sure severities are consistent across events. type: long example: |
core |
event.start |
event.start contains the date when the event started or when the activity was first observed. type: date |
extended |
event.timezone |
This field should be populated when the event’s timestamp does not include timezone information already (e.g. default Syslog timestamps). It’s optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00"). type: keyword |
extended |
event.type |
Reserved for future usage. Please avoid using this field for user data. type: keyword |
