Soaking collectd restart with pmond out of the picture.

#!/bin/bash
LOOPS=1000
old_pid=`cat /var/run/collectd.pid`
for ((loop=0;loop<${LOOPS};loop++))
do
    date
    systemctl restart collectd
    sleep 5
    if [ ! -e /var/run/collectd.pid ] ; then
        echo "No PIDFILE";
        exit 1
    fi
    new_pid=`cat /var/run/collectd.pid`
    if [ "$old_pid" == "$new_pid" ] ; then
        echo "Error: same PID"
        exit 2
    fi
    echo "New Pid $loop: $new_pid"
    old_pid=$new_pid
done
