Domoticz

Posted: **Tuesday 20 September 2016 10:08**

I was looking to manage my home network and to be notified for any outages. I have been looking at tools like OpenNMS, Cacti etc but I found them all to be quite complex for my needs. So I decided to try and use my Domoticz set for this purpose and have build the following config:

Internet Connection Monitoring.

Set-up the script defined here: viewtopic.php?f=28&t=11970
This provides me with ping time and current upload and download speed.

Ping Devices:
For every device I wanted to measure I made a Custom Sensor, value ms (milliseconds)
Created a standard script:

Ping.sh

Code: Select all

host=$1
count=$2
idx=$3
name=$4
domoticz=127.0.0.1

value=`ping -c $count $host | awk -F '/' 'END {print $5}'`
echo "$4 $value"
curl "$domoticz:8080/json.htm?type=command&param=udevice&idx=$idx&nvalue=0&sval$

Create a scheduled script:

In the Vars section I put all the devices I wanted to check.
syntax is “IP-address #of pings VirtualSwitch Description”
There is some logging in /home/pi/domoticz/scripts/pingall.log, used for troubleshooting

pingall.sh

Code: Select all

echo start >> /home/pi/domoticz/scripts/pingall.log
date >> /home/pi/domoticz/scripts/pingall.log

vars=(
"192.168.0.1 3 773 Ziggo"
"192.168.1.254 3 774 Linksys"
"192.168.1.253 3 775 Synology"
"192.168.1.175 3 776 ESX"

"192.168.1.199 3 783 Synology2"
"192.168.1.119 3 784 RP-AC52"
)

echo $vars >> /home/pi/domoticz/scripts/pingall.log
for v in "${vars[@]}";

do
echo $v  >> /home/pi/domoticz/scripts/pingall.log
/home/pi/domoticz/scripts/ping.sh $v  >> /home/pi/domoticz/scripts/pingall.log;

done

#date >> /home/pi/domoticz/scripts/pingall.log
echo done >> /home/pi/domoticz/scripts/pingall.log

Check open ports:

To check if applications are functioning I decided to check if the TCP ports are open. I use nmap for this. If it’s not available, you can install it via apt:
sudo apt-get install nmap

Created a standard script:

nmap.sh

Code: Select all

host=$1
port=$2
idx=$3
name=$4
domoticz=127.0.0.1
value=

value=`nmap $host -p $port | grep closed`
echo "$4 $value"
if  [ -n "$value" ]
then echo "port closed"
curl "$domoticz:8080/json.htm?type=command&param=switchlight&idx=$idx&switchcmd=Off"
##echo "$domoticz:8080/json.htm?type=command&param=switchlight&idx=$idx&&switchcmd=Off"
else echo "port open"
curl "$domoticz:8080/json.htm?type=command&param=switchlight&idx=$idx&switchcmd=On"
fi

Created a scheduled script:
In the Vars section I put all the devices and Ports I wanted to check.
syntax is “IP-address Port# VirtualSwitch Description”
Description is not used, only for my own reference.

There is some logging in /home/pi/domoticz/scripts/nmapall.log, used for troubleshooting

nmapall.sh

I created a nice image for the the floorplan, added the created Switches and Sensors. Also the Standard Motherboard Monitors for my Pi and now I have the following overview of my network:

I can use the logging to see when there was anything wrong with a device, like this example when my Linksys router was acting up.

Let me know what you think and if you have any suggestions!

will do the same as soon as I can!!!

Nice!
Looks really good and a breeze to administrate if you know your way around in Domoticz.
I will have to make a setup for my own net - thanks for sharing!!

Thanks, if you make something nice, please share!

sweet!

this is added to my todo list!
likely with the addition to send out alarm emails to me when times are outside normal values 3 sigma limits or so...

what kind of sensor did you use? or how did you create it?
because if i use a counter, the values are all noted in full numbers and the ms from the ping are not correctly displayed in domoticz

Posted: **Monday 17 October 2016 11:06**

fixed it by using a counter and multiply the ping result with 1000 to convert to ms before sending it to domoticz

I just use a "custom" sensor, and label it "ms"
My values are noted in *.*** ms

Great stuff!!!
Real you all make my days to sort.....
This one is on my bucket list..

What do you have for other options whit this option

Found a little issue with nmap.sh.
If a host is down, nmap will report that instead of using the word closed. So I changed the grep to:

Code: Select all

value=`nmap $host -p $port -Pn | grep 'closed\|down\|filtered'`

so now the light icons for the ports go out if the host is down

Also changed ping.sh to

Code: Select all


host=$1
count=$2
idx=$3
name=$4
domoticz=127.0.0.1

value=`ping -c $count $host | awk -F '/' 'END {print $5}'`
echo "$4 $value"
 if [ $value = ""]; then
               value=99999
            fi
curl "$domoticz:8080/json.htm?type=command&param=udevice&idx=$idx&nvalue=0&svalue=$value

This will set the ping counter to 99999ms if the host is down. Makes it easier to send alarm if the value is higher than ......

Thanx for sharing this.

Going to use this for my systemcontrol page!

I added my versions of the script and more network monitoring in this topic:
viewtopic.php?f=23&t=15553

I'm also runing uptime counters and device on timers

I`m getting following error when running pingall.sh

Code: Select all

pi@raspberrypi:~/domoticz/scripts $ sh pingall.sh
: not found 3: pingall.sh:
pingall.sh: 4: pingall.sh: Syntax error: "(" unexpected

My scriptfile is looking like this:

Code: Select all

echo start >> /home/pi/domoticz/scripts/pingall.log

ok found the error. Added bin/bash to script and ran it as bash script and it works now. The ping.sh has to be edited for use with domoticz. The script wasn`t working for me. This one worked for me:

Code: Select all

#!/bin/bash
host=$1
count=$2
idx=$3
name=$4
domoticz=127.0.0.1
port=8080

value=`ping -c $count $host | awk -F '/' 'END {print $5}'`

#output if you run it manually
printf "$4 ping = $ping ms"

curl -s -i -H "Accept: application/json" "http://$domoticz:$port/json.htm?type=command&param=udevice&idx=$idx&svalue=$value"

Hmm.. Definitely worth adding to Domoticz. Thanks for the inspiration!
