Service Fields

service.ephemeral_id

Ephemeral identifier of this service (if one exists).

This id normally changes across restarts, but service.id does not.

type: keyword

example: 8a4f500f

extended

service.id

Unique identifier of the running service. If the service is comprised of many nodes, the service.id should be the same for all nodes.

This id should uniquely identify the service. This makes it possible to correlate logs and metrics for one specific service, no matter which particular node emitted the event.

Note that if you need to see the events from one specific host of the service, you should filter on that host.name or host.id instead.

type: keyword

example: d37e5ebfe0ae6c4972dbe9f0174a1637bb8247f6

core

service.name

Name of the service data is collected from.

The name of the service is normally user given. This allows for distributed services that run on multiple hosts to correlate the related instances based on the name.

In the case of Elasticsearch the service.name could contain the cluster name. For Beats the service.name is by default a copy of the service.type field if no name is specified.

type: keyword

example: elasticsearch-metrics

core

service.node.name

Name of a service node.

This allows for two nodes of the same service running on the same host to be differentiated. Therefore, service.node.name should typically be unique across nodes of a given service.

In the case of Elasticsearch, the service.node.name could contain the unique node name within the Elasticsearch cluster. In cases where the service doesn’t have the concept of a node name, the host name or container name can be used to distinguish running instances that make up this service. If those do not provide uniqueness (e.g. multiple instances of the service running on the same host) - the node name can be manually set.

type: keyword

example: instance-0000000016

extended

service.state

Current state of the service.

type: keyword

core

service.type

The type of the service data is collected from.

The type can be used to group and correlate logs and metrics from one service type.

Example: If logs or metrics are collected from Elasticsearch, service.type would be elasticsearch.

type: keyword

example: elasticsearch

core

service.version

Version of the service the data was collected from.

This allows to look at a data set only for a specific version of a service.

type: keyword

example: 3.2.4
