-# Metrics file for the curl plugin
-#
-# 2022-02-15: rewritten form cmk 2.0, based on the work by doc[at]snowheaven[dot]de
-# 2022-02-20: added num_connects, num_redirects, size_download, size_header and speed_download
-# 2022-03-13: moved cert time left graph to the end of graphs
-# 2022-05-17: added scalars to cert_time_left
