Enterprise
GEL Configuration reference
Grafana Enterprise Logs can be configured using a YAML file - specified using the -config.file flag - or CLI flags. In case you combine both, CLI flags take precedence over the YAML config file.
The current configuration of any GEL component can be seen by visiting the /config HTTP path.
Passwords are filtered out of this endpoint.
Reference
To specify which configuration file to load, pass the -config.file flag at the command line. The file is written in YAML format, defined by the scheme below. Brackets indicate that a parameter is optional.
For Loki general configurations (ex: compactor, ingester configuration docs), see the Loki Configuration Reference.
Generic placeholders
<boolean>: a boolean that can take the valuestrueorfalse<int>: any integer matching the regular expression[1-9]+[0-9]*<duration>: a duration matching the regular expression[0-9]+(ns|us|µs|ms|s|m|h|d|w|y)where y = 365 days<string>: a regular string<url>: a URL<prefix>: a CLI flag prefix based on the context (look at the parent configuration block to see which CLI flags prefix should be used)<time>: a timestamp, with available formats:2006-01-20(midnight, local timezone),2006-01-20T15:04(local timezone), and RFC 3339 formats:2006-01-20T15:04:05Z(UTC) or2006-01-20T15:04:05+07:00(explicit timezone)
Use environment variables in the configuration
You can use environment variable references in the config file to set values that need to be configurable during deployment by using the -config.expand-env flag.
To do this, use:
${VAR}Where VAR is the name of the environment variable.
Each variable reference is replaced at startup by the value of the environment variable. The replacement is case-sensitive and occurs before the YAML file is parsed. References to undefined variables are replaced by empty strings unless you specify a default value or custom error text.
To specify a default value, use:
${VAR:default_value}Where default_value is the value to use if the environment variable is undefined.
