# Example script used to execute an alert action.
#
# This script assumes that you symlink your alert scripts like this:
# disk.pendsect-alert.sh -> monitorix-alert.sh
# disk.realloc-alert.sh -> monitorix-alert.sh
# mail.mqueued-alert.sh -> monitorix-alert.sh
# system.loadavg-alert.sh -> monitorix-alert.sh
# ...
# So you only use one script (saving disk space) and its prefix will
# appear in the subject and contents of the email, so you will easily
# identify the source of the alert.
