# == Class: icinga2::feature::perfdata
#
# This module configures the Icinga 2 feature perfdata.
#
# === Parameters
#
# [*ensure*]
#   Set to present enables the feature perfdata, absent disables it. Defaults to present.
#
# [*host_perfdata_path*]
#   Absolute path to the perfdata file for hosts. Default depends on platform:
#   /var/spool/icinga2/host-perfdata on Linux
#   C:/ProgramData/icinga2/var/spool/icinga2/host-perfdata on Windows.
#
# [*service_perfdata_path*]
#   Absolute path to the perfdata file for services. Default depends on platform:
#   /var/spool/icinga2/service-perfdata on Linux
#   C:/ProgramData/icinga2/var/spool/icinga2/service-perfdata on Windows.
#
# [*host_temp_path*]
#   Path to the temporary host file. Defaults depends on platform:
#   /var/spool/icinga2/tmp/host-perfdata on Linux
#   C:/ProgramData/icinga2/var/spool/icinga2/tmp/host-perfdata on Windows.
#
# [*service_temp_path*]
#   Path to the temporary service file. Defaults depends on platform:
#   /var/spool/icinga2/tmp/host-perfdata on Linux
#   C:/ProgramData/icinga2/var/spool/icinga2/tmp/host-perfdata on Windows.
#
# [*host_format_template*]
#   Host Format template for the performance data file. Defaults to a template that's suitable for use with PNP4Nagios.
#
# [*service_format_template*]
#   Service Format template for the performance data file. Defaults to a template that's suitable for use with
#   PNP4Nagios.
#
# [*rotation_interval*]
#   Rotation interval for the files specified in {host,service}_perfdata_path. Can be written in minutes or seconds,
#   i.e. 1m or 15s. Defaults to 30s.
#
