# This script was written to find out which opsi products failed recently.
# opsi-admin returns a list of all products where state is "unknown" and action
# is "none". This script just saves the list and compares it to the list it got
# last time. After that, this script tries to get the cause of the error by
# grep for "fatal error" at the opsi logfile.
 
# You can also start this script by cron and configure cron to mail the output.
