Packetbeat command reference

edit

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

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
  • Packetbeat 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.

Commands

export

Exports the configuration, index template, ILM policy, or a dashboard to stdout.

help

Shows help for any command.

keystore

Manages the secrets keystore.

run

Runs Packetbeat. This command is used by default if you start Packetbeat without specifying a command.

setup

Sets up the initial environment, including the index template, ILM policy and write alias, and Kibana dashboards (when available).

test

Tests the configuration.

version

Shows information about the current version.

Also see Global flags.

export command

edit

Exports the configuration, index template, ILM policy, or a dashboard 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 a dashboard from Kibana.

SYNOPSIS

packetbeat 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.
dashboard

Exports a dashboard. You can use this option to store a dashboard on disk in a module and load it automatically. For example, to export the dashboard to a JSON file, run:

packetbeat export dashboard --id="DASHBOARD_ID" > dashboard.json

To find the DASHBOARD_ID, look at the URL for the dashboard in Kibana. By default, export dashboard writes the dashboard to stdout. The example shows how to write the dashboard to a JSON file so that you can import it later. The JSON file will contain the dashboard with all visualizations and searches. You must load the index pattern separately for Packetbeat.

To load the dashboard, copy the generated dashboard.json file into the kibana/6/dashboard directory of Packetbeat, and run packetbeat setup --dashboards to import the dashboard.

If Kibana is not running on localhost:5061, you must also adjust the Packetbeat configuration under setup.kibana.

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.

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.
--id DASHBOARD_ID
When used with dashboard, specifies the dashboard ID.

Also see Global flags.

EXAMPLES

packetbeat export config
packetbeat export template --es.version 8.15.4
packetbeat export dashboard --id="a7b35890-8baa-11e8-9676-ef67484126fb" > dashboard.json

keystore command

edit

Manages the secrets keystore.

SYNOPSIS

list
Lists the keys in the keystore.

Also see Global flags.

EXAMPLES

packetbeat keystore create
packetbeat keystore add ES_PWD
packetbeat keystore remove ES_PWD
packetbeat keystore list

See Secrets keystore for more examples.

run command

edit

Runs Packetbeat. This command is used by default if you start Packetbeat without specifying a command.

SYNOPSIS

packetbeat run [FLAGS]

Or:

packetbeat [FLAGS]

FLAGS

-I, --I FILE

Reads packet data from the specified file instead of reading packets from the network. This option is useful only for testing Packetbeat.

packetbeat run -I ~/pcaps/network_traffic.pcap
-N, --N
Disables publishing for testing purposes. This option disables all outputs except the File output.
-O, --O
Read packets one by one by pressing Enter after each. This option is useful only for testing Packetbeat.
--cpuprofile FILE
Writes CPU profile data to the specified file. This option is useful for troubleshooting Packetbeat.
-devices
Prints the list of devices that are available for sniffing and then exits.
-dump FILE
Writes all captured packets to the specified file. This option is useful for troubleshooting Packetbeat.
-h, --help
Shows help for the run command.
--httpprof [HOST]:PORT
Starts an http server for profiling. This option is useful for troubleshooting and profiling Packetbeat.
-l N
Reads the pcap file N number of times. The default is 1. Use this option in combination with the -I option. For an infinite loop, use 0. The -l option is useful only for testing Packetbeat.
--memprofile FILE
Writes memory profile data to the specified output file. This option is useful for troubleshooting Packetbeat.
--system.hostfs MOUNT_POINT
Specifies the mount point of the host’s filesystem for use in monitoring a host. This flag is depricated, and an alternate hostfs should be specified via the hostfs module config value.
-t
Reads packets from the pcap file as fast as possible without sleeping. Use this option in combination with the -I option. The -t option is useful only for testing Packetbeat.

Also see Global flags.

EXAMPLE

packetbeat run -e

Or:

packetbeat -e

setup command

edit

Sets up the initial environment, including the index template, ILM policy and write alias, and Kibana dashboards (when available)

  • 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 Kibana dashboards make it easier for you to visualize Packetbeat data in Kibana.

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

SYNOPSIS

packetbeat setup [FLAGS]

FLAGS

--dashboards
Sets up the Kibana dashboards (when available). This option loads the dashboards from the Packetbeat package. For more options, such as loading customized dashboards, see Importing Existing Beat Dashboards in the Beats Developer Guide.
-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.

EXAMPLES

packetbeat setup --dashboards
packetbeat setup --index-management

test command

edit

Tests the configuration.

SYNOPSIS

packetbeat test SUBCOMMAND [FLAGS]

SUBCOMMANDS

config
Tests the configuration settings.
output
Tests that Packetbeat can connect to the output by using the current settings.

FLAGS

-h, --help
Shows help for the test command.

Also see Global flags.

EXAMPLE

packetbeat test config

version command

edit

Shows information about the current version.

SYNOPSIS

packetbeat version [FLAGS]

FLAGS

-h, --help
Shows help for the version command.

Also see Global flags.

EXAMPLE

packetbeat version

Global flags

edit

These global flags are available whenever you run Packetbeat.

-E, --E "SETTING_NAME=VALUE"

Overrides a specific configuration setting. You can specify multiple overrides. For example:

packetbeat -E "name=mybeat" -E "output.elasticsearch.hosts=['http://myhost:9200']"

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

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

-e, --e
Logs to stderr and disables syslog/file output.
-environment
For logging purposes, specifies the environment that Packetbeat 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, Packetbeat will log to stdout and stderr by default.
--path.config
