# This function generates the command line flags passed to Prometheus at time of
|
|
# execution. This allows the Prometheus service configuration to be flexible, as
|
|
# the only way to define Prometheus's configuration is via command line flags.
|
|
# The yaml definition for these flags uses the full yaml path as the key, and
|
|
# replaces underscores with hyphens to match the syntax required for the flags
|
|
# generated (This is required due to Go's yaml parsing capabilities).
|
|
# For example:
|
|
#
|
|
# conf:
|
|
# prometheus:
|
|
# command_line_flags:
|
|
# storage.tsdb.max_block_duration: 2h
|
|
#
|
|
# Will generate the following flag:
|
|
# --storage.tsdb.max-block-duration=2h
|
|
#
|
|
# Prometheus's command flags can be found by either running 'prometheus -h' or
|
|
# 'prometheus --help-man'
