YAML Configuration Files
ElastiFlow now supports YAML configuration files for all binaries, with a default file location of /etc/elastiflow/<binary_name>.yml
. These YAML files are compatible with all existing ElastiFlow settings, which are documented in the Configuration Reference.
Although environment variables are still available for configuring the collector, the systemd attributes file may be removed in future releases.
To use a YAML file for configuration, either place it in the default location or specify a custom location with the --config
or -c
flag when running the binary:
./flowcoll --config=/etc/elastiflow/flowcoll.yml
or
./flowcoll -c=/etc/elastiflow/flowcoll.yml
Implementing YAML Configuration
This example demonstrates configuring logging settings for the ElastiFlow flow-collector binary using a flowcoll.yml
file:
-
Create a new file called
flowcoll.yml
with the following content.EF_LOGGER_LEVEL: 'info'
EF_LOGGER_ENCODING: 'json'
EF_LOGGER_FILE_LOG_ENABLE: true
EF_LOGGER_FILE_LOG_FILENAME: '/var/log/elastiflow/flowcoll/flowcoll.log'
EF_LOGGER_FILE_LOG_MAX_SIZE: 100
EF_LOGGER_FILE_LOG_MAX_AGE: 7
EF_LOGGER_FILE_LOG_MAX_BACKUPS: 4
EF_LOGGER_FILE_LOG_COMPRESS: false -
Customize the settings as needed and create additional YAML files for other ElastiFlow binaries if required.
-
Run the flowcoll binary with the
--config
flag, specifying the path to yourflowcoll.yml
file:./flowcoll --config=/path/to/flowcoll.yml
