# Script Name: alarm_nfs_1host
#
# Where:   in  $FEDIR/scripts   where  FEDIR=/apps/nns_com/fea
#
#             
# Purpose: To check the host that this script runs on for 'exception'/'alarm'
#          conditions -- with respect to 'nfsstat -cr':
#                          like 'badcalls'
#                                        greater than 5% of 'calls'.
#
#          Opens an alarm-msg-window on the host specified in $1.
#
#     Could send alarm messages/mail to I-DEAS Admin hosts/people
#                        -- like iaw030/bmo01, iaw070/rgb07, iaw025/wcs05.
#
#     Also could append the alarm messages to file $2 (a name passed to
#                                                             this script).
#
#
# Called by: $FEDIR/scripts/alarm_scan script  --- or manually
#
# Technique: 'alarm_scan' repeatedly does
#
#	rsh iaw### script	    where ### is 000, 001, 002, ..., 100, ...
#
#                where script is this script
#                                "$FEDIR/scripts/alarm_neti_1host $HOST4MSG"
#
# Written by: B. Montandon  5May97  to look for clients generating heavy I/O
