# This sample script assumes that only users who already have
# hacluster-equivalent access to the cluster nodes can edit the CIB. Otherwise,
# a malicious user could run commands as hacluster by inserting shell code into
# the trap_options or timestamp-format parameters.
#
# Sample configuration (cib fragment in xml notation)
# ================================
# <configuration>
#   <alerts>
#     <alert id="snmp_alert" path="/path/to/alert_snmp.sh">
