Elastic Agent command reference

edit

Elastic Agent provides commands for running Elastic Agent, managing Fleet Server, and doing common tasks.

You might need to log in as a root user (or Administrator on Windows) to run these commands. After the Elastic Agent service is installed and running, make sure you run these commands without prepending them with ./ to avoid invoking the wrong binary.


elastic-agent diagnostics

edit

Gather diagnostics information from the Elastic Agent and component/unit it’s running. This command produces an archive that contains:

  • version.txt - version information
  • pre-config.yaml - pre-configuration before variable substitution
  • variables.yaml - current variable contexts from providers
  • computed-config.yaml - configuration after variable substitution
  • components-expected.yaml - expected computed components model from the computed-config.yaml
  • components-actual.yaml - actual running components model as reported by the runtime manager
  • state.yaml - current state information of all running components
  • goroutine.txt - goroutine dump
  • heap.txt - memory allocation of live objects
  • allocs.txt - sampling past memory allocations
  • threadcreate.txt - traces led to creation of new OS threads
  • block.txt - stack traces that led to blocking on synchronization primitives
  • mutex.txt - stack traces of holders of contended mutexes
  • components directory - diagnostic information from each running component (content defined by the inputs)

Note that credentials are not redacted in the archive; they may appear in plain text in the configuration or policy files inside the archive.

This command is intended for debugging purposes only. The output format and structure of the archive may change between releases.

elastic-agent enroll

edit

Enroll the Elastic Agent in Fleet.

Use this command to enroll the Elastic Agent in Fleet without installing the agent as a service. You will need to do this if you installed the Elastic Agent from a DEB or RPM package and plan to use systemd commands to start and manage the service. This command is also useful for testing Elastic Agent prior to installing it.

If you’ve already installed Elastic Agent, use this command to modify the settings that Elastic Agent runs with.

To enroll an Elastic Agent and install it as a service, use the install command instead. Installing as a service is the most common scenario.

We recommend that you run the enroll (or install) command as the root user because some integrations require root privileges to collect sensitive data. This command overwrites the elastic-agent.yml file in the agent directory.

This command includes optional flags to set up Fleet Server.

This command enrolls the Elastic Agent in Fleet; it does not start the agent. To start the agent, either start the service, if one exists, or use the run command to start the agent from a terminal.

                     [global-flags]

If no fleet-server-cert* flags are specified, Elastic Agent auto-generates a self-signed certificate with the hostname of the machine. Remote Elastic Agents enrolling into a Fleet Server with self-signed certificates must specify the --insecure flag.

Required when using self-signed certificates with Elasticsearch.

Required when enrolling in a Fleet Server with custom certificates. The URL must match the DNS name used to generate the certificate specified by --fleet-server-cert.

For more information about custom certificates, refer to Configure SSL/TLS for self-managed Fleet Servers.

Options

edit

Comma-separated list of certificate authority hash pins used for certificate verification.
--certificate-authorities <string>
Comma-separated list of root certificates used for server verification.
--delay-enroll
Delays enrollment to occur on first start of the Elastic Agent service. This setting is useful when you don’t want the Elastic Agent to enroll until the next reboot or manual start of the service, for example, when you’re preparing an image that includes Elastic Agent.
--enrollment-token <string>
Enrollment token to use to enroll Elastic Agent into Fleet. You can use the same enrollment token for multiple agents.
--fleet-server-cert <string>
Certificate to use for exposed Fleet Server HTTPS endpoint.
--fleet-server-cert-key <string>
Private key to use for exposed Fleet Server HTTPS endpoint.
--fleet-server-cert-key-passphrase <string>
Path to passphrase file for decrypting Fleet Server’s private key if an encrypted private key is used.
--fleet-server-es <string>
Start a Fleet Server process when Elastic Agent is started, and connect to the specified Elasticsearch URL.
--fleet-server-es-ca <string>
Path to certificate authority to use to communicate with Elasticsearch.
--fleet-server-es-ca-trusted-fingerprint <string>
The SHA-256 fingerprint (hash) of the certificate authority used to self-sign Elasticsearch certificates. This fingerprint will be used to verify self-signed certificates presented by Fleet Server and any inputs started by Elastic Agent for communication. This flag is required when using self-signed certificates with Elasticsearch.
--fleet-server-es-insecure

Allows fleet server to connect to Elasticsearch in the following situations:

  • When connecting to an HTTP server.
  • When connecting to an HTTPs server and the certificate chain cannot be verified. The content is encrypted, but the certificate is not verified.

When this flag is used the certificate verification is disabled.

--fleet-server-host <string>
Fleet Server HTTP binding host (overrides the policy).
--fleet-server-insecure-http
Expose Fleet Server over HTTP. This option is not recommended because it’s insecure. It’s useful during development and testing, but should not be used in production. When using this option, you should bind Fleet Server to the local host (this is the default).
--fleet-server-policy <string>
Used when starting a self-managed Fleet Server to allow a specific policy to be used.
--fleet-server-port <uint16>
Fleet Server HTTP binding port (overrides the policy).
--fleet-server-service-token <string>
Service token to use for communication with Elasticsearch. Mutually exclusive with --fleet-server-service-token-path.
--fleet-server-service-token-path <string>
Service token file to use for communication with Elasticsearch. Mutually exclusive with --fleet-server-service-token.
--force

Force overwrite of current configuration without prompting for confirmation. This flag is helpful when using automation software or scripted deployments.

If the Elastic Agent is already installed on the host, using --force may result in unpredictable behavior with duplicate Elastic Agents appearing in Fleet.

--non-interactive
Install Elastic Agent in a non-interactive mode. This flag is helpful when using automation software or scripted deployments. If Elastic Agent is already installed on the host, the installation will terminate.
--help
Show help for the enroll command.
--insecure

Allow the Elastic Agent to connect to Fleet Server over insecure connections. This setting is required in the following situations:

  • When connecting to an HTTP server. The API keys are sent in clear text.
  • When connecting to an HTTPs server and the certificate chain cannot be verified. The content is encrypted, but the certificate is not verified.
  • When using self-signed certificates generated by Elastic Agent.

We strongly recommend that you use a secure connection.

--tag <string>

A comma-separated list of tags to apply to Fleet-managed Elastic Agents. You can use these tags to filter the list of agents in Fleet.

Currently, there is no way to remove or edit existing tags. To change the tags, you must unenroll the Elastic Agent, then re-enroll it using new tags.

--url <string>
Fleet Server URL to use to enroll the Elastic Agent into Fleet.

For more flags, see Global flags.

Examples

edit

Enroll the Elastic Agent in Fleet:

elastic-agent enroll \
  --url=https://cedd4e0e21e240b4s2bbbebdf1d6d52f.fleet.eu-west-1.aws.cld.elstc.co:443 \
  --enrollment-token=NEFmVllaa0JLRXhKebVKVTR5TTI6N2JaVlJpSGpScmV0ZUVnZVlRUExFQQ==

Enroll the Elastic Agent in Fleet and set up Fleet Server:

elastic-agent enroll --fleet-server-es=http://elasticsearch:9200 \
  --fleet-server-service-token=AbEAAdesYXN1abMvZmxlZXQtc2VldmVyL3Rva2VuLTE2MTkxMzg3MzIzMTg7dzEta0JDTmZUcGlDTjlwRmNVTjNVQQ \
  --fleet-server-policy=a35fd520-26f5-11ec-8bd9-3374690g57b6

Start Elastic Agent with Fleet Server (running on a custom CA). This example assumes you’ve generated the certificates with the following names:

  • ca.crt: Root CA certificate
  • fleet-server.crt: Fleet Server certificate
  • fleet-server.key: Fleet Server private key
  • elasticsearch-ca.crt: CA certificate to use to connect to Elasticsearch
elastic-agent enroll \
  --url=https://fleet-server:8220 \
  --fleet-server-es=https://elasticsearch:9200 \
  --fleet-server-service-token=AAEBAWVsYXm0aWMvZmxlZXQtc2XydmVyL3Rva2VuLTE2MjM4OTAztDU1OTQ6dllfVW1mYnFTVjJwTC2ZQ0EtVnVZQQ \

elastic-agent install

edit

Install Elastic Agent permanently on the system and manage it by using the system’s service manager. The agent will start automatically after installation is complete. On Linux (tar package), this command requires a system and service manager like systemd.

If you installed Elastic Agent from a DEB or RPM package, the install command will skip the installation itself and function as an alias of the enroll command instead.

You must run this command as the root user (or Administrator on Windows) to write files to the correct locations. This command overwrites the elastic-agent.yml file in the agent directory.

The syntax for running this command varies by platform. For platform-specific examples, refer to Install Elastic Agents.

Synopsis
