The Feature Flags section of the
heartbeat.yml config file contains
settings in Heartbeat that are disabled by default. These may include
experimental features, changes to behaviors within Heartbeat, or
settings that could cause a breaking change. For example a
setting that changes information included in events might be inconsistent with
the naming pattern expected in your configured Heartbeat output.
To enable any of the settings listed on this page, change the associated
features: mysetting: enabled: true
You can specify the following options in the
features section of the
heartbeat.yml config file:
Contains configuration for the FQDN reporting feature. When this feature is
enabled, the fully-qualified domain name for the host is reported in the
host.name field in events produced by Heartbeat.
This functionality is in technical preview and may be changed or removed in a future release. Elastic will apply best effort to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
For FQDN reporting to work as expected, the hostname of the current host must either:
- Have a CNAME entry defined in DNS.
- Have one of its corresponding IP addresses respond successfully to a reverse DNS lookup.
If neither pre-requisite is satisfied,
host.name continues to report the
hostname of the current host as if the FQDN feature flag were not enabled.
features: fqdn: enabled: true
