Logs app fieldsedit

This section lists the required fields the Logs app uses to display data. Please note that some of the fields listed are not ECS fields.

@timestamp

Date/time when the event originated.

This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events.

type: date

required: True

ECS field: True

example: May 27, 2020 @ 15:22:27.982

_doc

This field is used to break ties between two entries with the same timestamp.

required: True

ECS field: False

container.id

Unique container id.

type: keyword

required: True

ECS field: True

example: data

event.dataset

Name of the dataset.

If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from.

It’s recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name.

type: keyword

required: True, if you want to use the machine learning features.

ECS field: True

example: apache.access

host.hostname

Name of the host.

It normally contains what the hostname command returns on the host machine.

type: keyword

required: True, if you want to enable and use the View in Context feature.

ECS field: True

example: Elastic.local

host.name

Name of the host.

It can contain what hostname returns on Unix systems, the fully qualified domain name, or a name specified by the user. The sender decides which value to use.

type: keyword

required: True

ECS field: True

example: MacBook-Elastic.local

kubernetes.pod.uid

Kubernetes Pod UID.

type: keyword

required: True

ECS field: False

example: 8454328b-673d-11ea-7d80-21010a840123

log.file.path

Full path to the log file this event came from, including the file name. It should include the drive letter, when appropriate.

If the event wasn’t read from a log file, do not populate this field.

type: keyword

required: True, if you want to use the View in Context feature.

ECS field: True

example: /var/log/demo.log

message

For log events the message field contains the log message, optimized for viewing in a log viewer.

For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event.

If multiple messages exist, they can be combined into one message.

type: text

required: True

ECS field: True

example: Hello World
