The following script can be used for nagios to contact the mirrolist
servers and query the age of the pickle currently loaded.
This output of the script looks like this:
$./check_mirrorlist_pkl_age.py 02 3000 5000
WARN: mirrorlist data on proxy02 older than 3000s (3894s)
$ ./check_mirrorlist_pkl_age.py 14 5000 7000
OK: up-to-date mirrorlist data on proxy14 (3921s)
$ ./check_mirrorlist_pkl_age.py 08 2000 3000
CRIT: mirrorlist data on proxy08 older than 3000s (3938s)

+# Script to check the age of the data used by the mirrorlist servers.
+#
+# Fedora's mirrorlist server are using a python pkl which has the creation
+# date embedded. Querying the mirrorlist interface with '&time' returns
+# that timestamp:
+#
+# '# database creation time: <timestamp>'
+#
+# This script connects to the specified proxy and reads out that value
+# and compares it with a warning and critical threshold.
+#
+# Tested with python2 and python3
+#
+# Requires python[2,3]-requests
+#
+# Usage:
+# check_mirrorlist_pkl_age.py <proxy-number> <warning> <critical>
+# check_mirrorlist_pkl_age.py 12 3600 7200
