### Welcome to the InfluxDB Cluster configuration file.

# The values in this file override the default values used by the system if
# a config option is not specified. The commented out lines are the configuration
# field and the default value used. Uncommenting a line and changing the value
# will change the value used at runtime when the process is restarted.

# Once every 24 hours InfluxDB Cluster will report usage data in log output
# The data includes a random ID, os, arch, version, the number of series and other
# usage data. No data from user databases is ever transmitted.
# Change this option to true to disable reporting.

### [logging]
###
### Controls how the logger emits logs to the output.
###

[logging]

# are auto, logfmt, and json. auto will use a more a more user-friendly
# output format if the output terminal is a TTY, but the format is not as
# easily machine-readable. When the output is a non-TTY, auto will use
# logfmt.

# are error, warn, info, and debug. Logs that are equal to or above the
# specified level will be emitted.

# The logo is always suppressed if STDOUT is not a TTY.

[tls]
# Determines the available set of cipher suites. See https://golang.org/pkg/crypto/tls/#pkg-constants
# for a list of available ciphers, which depends on the version of Go (use the query
# SHOW DIAGNOSTICS to see the version of Go used to build InfluxDB). If not specified, uses
# the default settings from Go's crypto/tls package.
