ECS 8.3.0

What's new in ECS 8.3

GA additions to the schema

The container.* metrics fieldset

Proposed in RFC 0025, this release introduces the container.* field set as GA. These additional container metric fields capture container CPU, memory, disk and network performance information.

Pattern attribute for .mac fields

ECS sets the pattern attribute for the .mac address fields. The regex value is based on the format suggested in IETF RFC 7042.

Schema Changes

Added

• Added pattern attribute to .mac fields. #1871
• Add orchestrator.cluster.id #1875
• Add orchestrator.resource.id #1878
• Add orchestrator.resource.parent.type #1889
• Add orchestrator.resource.ip #1889
• Add container.image.hash.all #1889
• Add service.node.role #1916
• Advanced container.* metric fields to GA. #1927

Important

After adding service.node.role, it was realized that we intend for this field to have multiple values, and therefore we will be removing role and replacing with roles at the earliest opportunity. Please do not use service.node.role.

ECS 8.2.0

What's new in ECS 8.2

Beta additions to the schema

The linux event model fields

Proposed in RFC 0030, this release introduces a variety of new beta fields that model a linux event model in order to drive Session view in Kibana.

The container.* metrics fieldset

Proposed in RFC 0025, this release introduces a beta container.* field set. These additional container metric fields capture container CPU, memory, disk and network performance information.

Tooling improvements

In 8.2, ECS has introduced a new optional field definition attribute: pattern. The pattern attribute holds a regular expression (regex) which expresses the expected constraint on a string field's value. This field is intended to be utilized in automated testing for validation of the values populating ECS fields.
