Elastic Agent standalone configuration
editElastic Agent standalone configuration
editRunning Elastic Agent in standalone mode is an advanced use case. The documentation is incomplete and not yet mature. When possible, we recommend using Fleet-managed agents instead of standalone mode.
To get started quickly, use Kibana to create and download a standalone policy file. You’ll still need to deploy and manage the file, though. For more information, refer to Create a standalone Elastic Agent policy.
Standalone Elastic Agents are manually configured and managed locally on the systems where they are installed. They are useful when you are not interested in centrally managing agents in Fleet, either due to your company’s security requirements, or because you prefer to use another configuration management system.
To configure standalone Elastic Agents, specify settings in the elastic-agent.yml
policy file deployed with the agent. Prior to installation,
the file is located in the extracted Elastic Agent package. After installation, the
file is copied to the directory described in Installation layout. To apply
changes after installation, you must modify the installed file.
For installation details, refer to Install standalone Elastic Agents (advanced users).
Alternatively, you can put input configurations in YAML files into the
folder {path.config}/inputs.d to separate your configuration into
multiple smaller files.
The YAML files in the inputs.d folder should contain input configurations only.
Any other configurations are ignored.
The files are reloaded at the same time as the standalone configuration.
The first line of the configuration must be inputs. Then you can list the
inputs you would like to run.
inputs:
- type: logfile
data_stream.namespace: default
paths: [/path/to/file]
use_output: default
- type: system/metrics
data_stream.namespace: default
use_output: default
streams:
- metricset: cpu
data_stream.dataset: system.cpu
The following sections describe some settings you might need to configure to run an Elastic Agent standalone. For a full reference example, refer to the elastic-agent.reference.yml file.
The settings described here are available for standalone Elastic Agents. Settings for Fleet-managed agents are specified through the UI. You do not set them explicitly in a policy file.
