Stacked monitoring?

Hi!

$? would give the status of the last command so you need to test them independently.

tmsh show ltm pool Mypool1_Stg_pool field-fmt | grep -o offline > /dev/null
tmsh show ltm pool Mypool2_Stg_pool field-fmt | grep -o offline > /dev/null

status=$?

This would only return the exit code of:

tmsh show ltm pool Mypool2_Stg_pool field-fmt | grep -o offline > /dev/null

Example:

This command works:
[root@PatrikLab:Active] config  ls bigip.conf > /dev/null
[root@PatrikLab:Active] config  echo $?
0

This command does not work:
[root@PatrikLab:Active] config  ls nonexistingfile > /dev/null
ls: nonexistingfile: No such file or directory
[root@PatrikLab:Active] config  echo $?
2

Run them together:
[root@PatrikLab:Active] config  ls nonexistingfile > /dev/null
ls: nonexistingfile: No such file or directory
[root@PatrikLab:Active] config  ls bigip.conf > /dev/null
[root@PatrikLab:Active] config  echo $?
0

So maybe you'd want to do something like this?

!/bin/sh

pidfile="/var/run/pinger.$1..$2.pid"

if [ -f $pidfile ]
then
   kill -9 `cat $pidfile` > /dev/null 2>&1
fi

echo "$$" > $pidfile

node_ip=`echo $1 | sed 's/::ffff://'`

status="UP"

tmsh show ltm pool Mypool1_Stg_pool field-fmt | grep -o offline > /dev/null
if [ $? ]; then
    status="DOWN";
fi
tmsh show ltm pool Mypool2_Stg_pool field-fmt | grep -o offline > /dev/null
if [ $? ]; then
    $status="DOWN"
fi

echo $status
