[Xymon] Ext script not looping

Ensure ssh isn't reading from standard input by using the -n option:

ZFSHEALTH=/usr/local/bin/ssh -n $MACHINE "/sbin/zpool get health rpool" | grep ONLINE | wc -l

ZFSSTAT=ssh -n -q $MACHINE /sbin/zpool status rpool

I have this script work is failing on all hosts except the first one.

I have narrowed it down to the ssh statement. For some reason the ssh statement causes the script to exit after the first host.

Any ideas why the ssh statement would cause the ext script to exit after the first host ?

#!/bin/sh

export PATH=$PATH:/sbin:/bin:/usr/bin:/usr/local/bin:/usr/sbin:/usr/local/bin

HOSTTAG=zfsmon # What we put in hosts.cfg to trigger this test

COLUMN=zfs # Name of the column, often same as tag in hosts.cfg

$XYMONHOME/bin/xymongrep $HOSTTAG | while read L

do

    set $L  # To get one line of output from xymongrep


    HOSTIP="$1"

    MACHINEDOTS="$2"

    MACHINE=`echo $2 | $SED -e's/\./,/g'`


    COLOR=green

    MSG="&green $MACHINEDOTS : POOL OK "


    #... do the test, perhaps modify COLOR and MSG


    typeset ZFSSTAT=


    ZFSHEALTH=`/usr/local/bin/ssh $MACHINE "/sbin/zpool get health

rpool" | grep ONLINE | wc -l`

    if [ $ZFSHEALTH -ne 1 ]

    then

    COLOR=red

    MSG="&red $MACHINEDOTS : POOL ISSUE"

    fi


    ZFSSTAT=`ssh -q $MACHINE /sbin/zpool status rpool`


    $XYMON $XYMSRV "status $MACHINE.$COLUMN $COLOR `date`


    ${MSG}


    $ZFSSTAT

  "

Done
