Functionbeat command reference

edit

Functionbeat provides a command-line interface for starting Functionbeat and performing common tasks, like testing configuration files.

The command-line also supports global flags for controlling global behaviors.

Use sudo to run the following commands if:

  • the config file is owned by root, or
  • Functionbeat is configured to capture data that requires root access

Some of the features described here require an Elastic license. For more information, see https://www.elastic.co/subscriptions and License Management.

export command

edit

Exports the configuration, index template, or AWS CloudFormation template to stdout. You can use this command to quickly view your configuration, see the contents of the index template and the ILM policy, or export an CloudFormation template.

SYNOPSIS

functionbeat export SUBCOMMAND [FLAGS]

SUBCOMMANDS

config
Exports the current configuration to stdout. If you use the -c flag, this command exports the configuration that’s defined in the specified file.
template
Exports the index template to stdout. You can specify the --es.version flag to further define what gets exported. Furthermore you can export the template to a file instead of stdout by defining a directory via --dir.
ilm-policy
Exports the index lifecycle management policy to stdout. You can specify the --es.version and a --dir to which the policy should be exported as a file rather than exporting to stdout.
function FUNCTION_NAME
Exports an AWS CloudFormation template to stdout.

FLAGS

--es.version VERSION
When used with template, exports an index template that is compatible with the specified version. When used with ilm-policy, exports the ILM policy if the specified ES version is enabled for ILM.
-h, --help
Shows help for the export command.
--dir DIRNAME
Define a directory to which the template, pipelines, and ILM policy should be exported to as files instead of printing them to stdout.

Also see Global flags.

EXAMPLES

functionbeat export config
functionbeat export template --es.version 8.14.3
functionbeat export function cloudwatch

setup command

edit

Sets up the initial environment, including the ES index template, and ILM policy and write alias

  • The index template ensures that fields are mapped correctly in Elasticsearch. If index lifecycle management is enabled it also ensures that the defined ILM policy and write alias are connected to the indices matching the index template. The ILM policy takes care of the lifecycle of an index, when to do a rollover, when to move an index from the hot phase to the next phase, etc.
  • The machine learning jobs contain the configuration information and metadata necessary to analyze data for anomalies.

This command sets up the environment without actually running Functionbeat and ingesting data. Specify optional flags to set up a subset of assets.

SYNOPSIS

functionbeat setup [FLAGS]

FLAGS

-h, --help
Shows help for the setup command.
--index-management
Sets up components related to Elasticsearch index management including template, ILM policy, and write alias (if supported and configured).

Also see Global flags.

This setting is applied to the currently running Functionbeat process. The Functionbeat configuration file is not changed.

-c, --c FILE
Specifies the configuration file to use for Functionbeat. The file you specify here is relative to path.config. If the -c flag is not specified, the default config file, functionbeat.yml, is used.
-d, --d SELECTORS

-e, --e
Logs to stderr and disables syslog/file output.
-environment
For logging purposes, specifies the environment that Functionbeat is running in. This setting is used to select a default log output when no log output is configured. Supported values are: systemd, container, macos_service, and windows_service. If systemd or container is specified, Functionbeat will log to stdout and stderr by default.
