mini probe

It's not officially tested, but have you tried it already? As the prerequisites should be available on RHEL as well...

So i was able to get the prob installed with Python, but it is not creating the service to start the mini probe. Any suggestions?

Ok, i can get the probe to run on Redhat 6.7. The I will be looking into the issues with the scripts not running correctly.

We'll have to wait until the colleague who wrote the script is available; that will be next Monday :)

Hi,

I created an init script for CentOS 6 and have also fixed the problems with the probehealth and diskspace sensors. Here is the init script:

#!/usr/bin/env bash
#
# prtgprobe     PRTG Python Mini Probe
#
# chkconfig: 2345 90 10
### BEGIN INIT INFO
# Provides:          prtgprobe
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: will run the MiniProbe as service
# Description:       This will run the PRTG Python Miniprobe as a service
### END INIT INFO

# Change the next 3 lines to suit where you install your script and what you want to call it
DIR=/opt/miniprobe
DAEMON=$DIR/probe.py
DAEMON_NAME=prtgprobe

# This next line determines what user the script runs as.
# Root generally not recommended but necessary if you are using the Raspberry Pi GPIO from Python.
DAEMON_USER=prtgprobe

# The process ID of the script when it runs is stored here:
PIDFILE=/var/run/$DAEMON_NAME.pid

do_start () {
    echo -n "Starting $DAEMON_NAME: "
    sudo -u $DAEMON_USER $DAEMON &
    sleep 1
    ps -ef | grep -v grep | grep probe.py | awk '{print $2}' > $PIDFILE
    RETVAL=$?
    [ $RETVAL -eq 0 ] && echo_success || echo_failure
    echo
    return $RETVAL
}

do_stop () {
    echo -n "Shutting down $DAEMON_NAME:"
    if [ -e $PIDFILE ] ; then
        kill `cat $PIDFILE` >/dev/null 2>&1
        rm -f $PIDFILE
    fi
    RETVAL=$?
    [ $RETVAL -eq 0 ] && echo_success || echo_failure
    echo
    return $RETVAL
}

case "$1" in

    start|stop)
        do_${1}
        ;;

    restart|reload|force-reload)
        do_stop
        do_start
        ;;

    status)
        status -p $PIDFILE "$DAEMON"
        RETVAL=$?
        ;;
    *)
        echo "Usage: /etc/init.d/$DAEMON_NAME {start|stop|restart|status}"
        exit 1
        ;;

esac
exit 0

Here is a patch for diskspace.py:

Here is a patch for probehealth.py:

I also edited probe.py and miniprobe.py so that I could change the location of the probe.conf and probe.log file.

Hope this helps someone else,

Ben

Very nice, thanks a bunch! :) You may want to push your changes to https://github.com/PaesslerAG/PythonMiniProbe so we can review and integrate it :)
