Advanced network monitoring

franzelare · Post by **franzelare** » Thursday 19 January 2017 11:47

I have combined a few scripts in Domoticz to monitor my network performance that I like to share.

This is the floorplan with all my network vitals displayed in one quick overview

Checking if network devices are online
I have multiple scripts runing, first the ARP scan to detect if devices are on or off, this way you don't have to know the IP of the devices in your network and can use a DHCP server.
This script is based on this topic on domoticz forum: viewtopic.php?f=23&t=5256
I have 3 user variable strings with the mac addresses and device ID's with it.

Mysensor node online detection
For my mysensor units I have a watchdog script runing, that sends an on switch command to every mysensor unit (ESP units over WiFi and NRF24 units over the mysensor network mesh) every unit responds by toggeling the switch off again so I know the unit is still alive. For the ESP units I have a timeout of 1 minute in the hardware configuration in domoticz, so it will try to re-connect if there is no response to the heartbeat ChildID and on the mysensor nodes I have one output pin to pull the reset to ground in case no heartbeat ID is received for 5 minutes. with this watchdog script I assume a node to be dead when I miss 2 heartbeats, so I miss one and cannot connect again within 1 minute, meaning the node has crashed and need to wait until the watchdog timer on the unit runs out and a hard reset is done... (soft resets fail often on the ESP units) I also track failing nodes in a log file on the server.
for details see my post in this topic on the hardware and code: viewtopic.php?f=42&t=9775

Ping times inside my network
Secondly I run a Ping script for the main devices in my network that have a fixed IP, like ESP units that run as Mysensor nodes and my switches and network drives.
This is derrived from the arp scan script and this topic on the domoticz forum: viewtopic.php?f=38&t=13421
This is the time based lua script runing in domoticz

Since I want to update multiple customer counters, i need to do this through a bash script, since lua in domoticz will only update the last custom device called out to.

Reboot scripts
For the domoticz servers I use them to do a crosscheck if domoticz is still runing and if not reboot the server, since just restarting domoticz is not always working. I do this with a time based lua script on both servers

Spoiler: show

Code: Select all

PRINT_MODE = false					-- when true wil print output to log and send notifications

commandArray = {}
    if PRINT_MODE == true then
        print ("Checking if heating Pi 2 is online")
    end
        execcommand="sudo /home/pi/domoticz/scripts/bash/CheckOnline.sh"
        os.execute(execcommand)
return commandArray

calling out for the following bash script

Spoiler: show

Code: Select all

#!/bin/sh
# check domoticz
status=`curl -s -i -H "Accept: application/json" "http://192.168.2.141:8080/json.htm?type=devices&rid=1" | grep "status"| awk -F: '{print $2}'|sed 's/,//'| sed 's/\"//g'`
if [ $status ]
then
echo "Domoticz draait nog"
else
echo "Domoticz draait niet meer, rebooting server"
curl "http://127.0.0.1:8080/json.htm?type=command&param=switchlight&idx=146&switchcmd=On"
sshpass -p 'xxxxxxxx' ssh [email protected] 'sudo reboot'
fi

sshpass you have to login manually first to accept the key presented, but after that it will run from the script
The script switches a virtual switch to let me know it rebooted the other server, in the startup script of the other server it sends an off command again so I can see in the logging that the reboot was successful

Nice! I have a similar plan but I use Alert sensors as I do not need the real values of ping response and get a better visualisation as alert sensor has 3 states (green,orange,red)
