# esVersion.major

Deprecated manual override for the detected Elasticsearch/OpenSearch major version.

This parameter applies to omelasticsearch: Elasticsearch Output Module.

Name:

  esVersion.major

Scope:

  action

Type:

  integer

Default:

  action=0 (overridden when detection succeeds)

Required?:

  no

Introduced:

  at least 8.x, possibly earlier

## Description

Warning

This parameter is deprecated as of rsyslog 8.2510.0. The module performs a best-effort probe at startup to discover the target platform (Elasticsearch or OpenSearch) and its version, and `esVersion.major` is automatically updated with the detected major version when the probe succeeds.

Changed in version 8.2510.0: Automatically overridden when startup platform detection succeeds.

This setting is only consulted when detection fails or when no servers are reachable during startup. Administrators may keep it configured as a fallback for air-gapped or permission-restricted environments, but future releases may remove the option entirely.

## Action usage

    action(type="omelasticsearch" esVersion.major="...")
