# Script to demonstrate how to parse out the event info that comes from a
# Condition that is watching another Condition in a hierarchical cluster environment.
# The condition that is being watched is a batch event. This script will go th the
# node that has the watched condition, get the event batch file. And parse the file
# and then send email to a user with the detailed info of the events in the batch file.
# The batch file will be then deleted if -d flag is set.
# To use this script, create a Response that invokes this script with email address as the input.
# Then associate the Response with a Condition that is watching Conditions on other
# nodes. When the Conditions occur, this script will wall the relevant event information.
# This info that is passed into this sample is structured as follows:
# EMS Condition/Event:
# $ENV{ERRM_COND_NAME}
# $ENV{ERRM_TYPEID}
# ...
# $ENV{ERRM_NODE_NAME} --> SN
# $ENV{ERRM_RSRC_NAME} --> SN Condition
# $ENV{ERRM_VALUE} --> SN Event: LastBatchedEventFile
# $Saved
# $FileName
# $Size
