Print config (in YAML) that the influxd server would use if run with the current flags/env vars/config file.
|
|
|
|
The order of precedence for config options are as follows (1 highest, 3 lowest):
|
|
1. flags
|
|
2. env vars
|
|
3. config file
|
|
|
|
A config file can be provided via the INFLUXD_CONFIG_PATH env var. If a file is
|
|
not provided via an env var, influxd will look in the current directory for a
|
|
config.{json|toml|yaml|yml} file. If one does not exist, then it will continue unchanged.
|
|
|
|
See 'influxd -h' for the full list of config options supported by the server.
