To configure Filebeat, you edit the configuration file. The default
configuration file is called
filebeat.yml. The location of the file
varies by platform. To locate the file, see Directory layout.
There’s also a full example configuration file called
that shows all non-deprecated options.
See the Config File Format section of the Beats Platform Reference for more about the structure of the config file.
Here is a sample of the
filebeat section of the
filebeat.yml file. Filebeat uses predefined
default values for most configuration options.
filebeat.inputs: - type: log enabled: true paths: - /var/log/*.log #- c:\programdata\elasticsearch\logs\*
To configure Filebeat:
Define the path (or paths) to your log files.
For the most basic Filebeat configuration, you can define a single input with a single path. For example:
filebeat.inputs: - type: log enabled: true paths: - /var/log/*.log
The input in this example harvests all files in the path
/var/log/*.log, which means that Filebeat will harvest all files in the directory
/var/log/that end with
.log. All patterns supported by Go Glob are also supported here.
To fetch all files from a predefined level of subdirectories, the following pattern can be used:
/var/log/*/*.log. This fetches all
.logfiles from the subfolders of
/var/log. It does not fetch log files from the
/var/logfolder itself. Currently it is not possible to recursively fetch all files in all subdirectories of a directory.
Configure the output. Filebeat supports a variety of outputs, but typically you’ll either send events directly to Elasticsearch, or to Logstash for additional processing.
To send output directly to Elasticsearch (without using Logstash), set the location of the Elasticsearch installation:
If you’re running Elasticsearch on your own hardware, set the host and port where Filebeat can find the Elasticsearch installation. For example:
output.elasticsearch: hosts: ["myEShost:9200"]
If you plan to use the sample Kibana dashboards provided with Filebeat, configure the Kibana endpoint. You can skip this step if Kibana is running on the same host as Elasticsearch.
If Elasticsearch and Kibana are secured, set credentials in the
filebeat.ymlconfig file before you run the commands that set up and start Filebeat.
If you’re running Elasticsearch on your own hardware, specify your Elasticsearch and Kibana credentials:
This examples shows a hard-coded password, but you should store sensitive values in the secrets keystore.
passwordsettings for Kibana are optional. If you don’t specify credentials for Kibana, Filebeat uses the
passwordspecified for the Elasticsearch output.
To use the pre-built Kibana dashboards, this user must have the
kibana_userbuilt-in role or equivalent privileges.

To test your configuration file, change to the directory where the
Filebeat binary is installed, and run Filebeat in the foreground with
the following options specified:
./filebeat test config -e. Make sure your
config files are in the path expected by Filebeat (see Directory layout),
or use the
-c flag to specify the path to the config file.
