Add cloud metadata

The add_cloud_metadata processor enriches each event with instance metadata from the machine’s hosting provider. At startup it will query a list of hosting providers and cache the instance metadata.

The following cloud providers are supported:

The Alibaba Cloud and Tencent cloud providers are disabled by default, because they require to access a remote host. The providers setting allows users to select a list of default providers to query.

The simple configuration below enables the processor.

processors:
  - add_cloud_metadata: ~

The add_cloud_metadata processor has three optional configuration settings. The first one is timeout which specifies the maximum amount of time to wait for a successful response when detecting the hosting provider. The default timeout value is 3s.

If a timeout occurs then no instance metadata will be added to the events. This makes it possible to enable this processor for all your deployments (in the cloud or on-premise).

The second optional setting is providers. The providers settings accepts a list of cloud provider names to be used. If providers is not configured, then all providers that do not access a remote endpoint are enabled by default. The list of providers may alternatively be configured with the environment variable BEATS_ADD_CLOUD_METADATA_PROVIDERS, by setting it to a comma-separated list of provider names.

List of names the providers setting supports:

The third optional configuration setting is overwrite. When overwrite is true, add_cloud_metadata overwrites existing cloud.* fields (false by default).

The add_cloud_metadata processor supports SSL options to configure the http client used to query cloud metadata. See SSL for more information.

The metadata that is added to events varies by hosting provider. Below are examples for each of the supported providers.
