Here is the load sensor...it basically checks to see if a server is
running on the host, returning 1 if yes
and 0 if no. It currently contains diagnostic prints to my home directory.
It runs fine from the command prompt.
When is a user provided load monitor actually run? Every time the
scheduler runs?
#!/bin/bash
#PURPOSE SGE load monitor

echo "begin"
echo "$hst:earl_ecs_jun:1"
echo "end"
}
bad(){
echo "begin"
echo "$hst:earl_ecs_jun:0"
echo "end"
}
echo START `date` >>/home/elazarus/LD
hst=$(uname -n)

while [ 1 ] ; do
read input
result=$?
echo READ `date` >>/home/elazarus/LD
if [ $result != 0 ] ; then
exit 1

if [ "$input" = "quit" ] ; then
echo END `date` >>/home/elazarus/LD
exit 0
