Monitoring devices

Dashboard
1

Hello everyone !!

I hope you can help me, I am taking my first steps in the world of noder-red and I am looking forward to making a dashboard for monitoring the IP devices that I have in the offices of my work.
Basically I have these 4 offices, with their respective devices:

Office 1:

  • printer: 192.168.1.11
  • pc 1: 192.168.1.12
  • pc 2: 192.168.1.13
  • pc 3: 192.168.1.14

Office 2:

  • printer: 192.168.2.11
  • pc 1: 192.168.2.12
  • pc 2: 192.168.2.13
  • pc 3: 192.168.2.14

Office 3:

  • printer: 192.168.3.11
  • pc 1: 192.168.3.12
  • pc 2: 192.168.3.13
  • pc 3: 192.168.3.14

Office 4:

  • printer: 192.168.4.11
  • pc 1: 192.168.4.12
  • pc 2: 192.168.4.13
  • pc 3: 192.168.4.14

I started creating the tables with ui_tables and a function to be able to test and inject simulated data, in this way I could see that everything is going well in the status monitor.
Here is what I did so far.

[{"id":"8eb12775.483628","type":"inject","z":"f16e1fbf.b19a8","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[{\"ID\":\"01\",\"Oficina\":\"01\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 1\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"}, {\"ID\":\"02\",\"Oficina\":\"01\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 2\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"03\",\"Oficina\":\"01\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 3\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"04\",\"Oficina\":\"01\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 4\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"05\",\"Oficina\":\"02\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 1\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"06\",\"Oficina\":\"02\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 2\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"07\",\"Oficina\":\"02\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 3\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"08\",\"Oficina\":\"02\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 4\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"09\",\"Oficina\":\"03\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 1\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"10\",\"Oficina\":\"03\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 2\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"11\",\"Oficina\":\"03\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 3\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"},  {\"ID\":\"12\",\"Oficina\":\"03\",\"Latencia Print\":\"103\",\"Impresora\":\"ok\",\"PC 4\":\"ok\",\"PC 2\":\"ok\",\"PC 3\":\"ok\"}   ]","payloadType":"json","x":270,"y":160,"wires":[["5592d69.1974928"]]},{"id":"5592d69.1974928","type":"ui_table","z":"f16e1fbf.b19a8","group":"8b1db693.daf448","name":"","order":4,"width":0,"height":0,"columns":[],"outputs":0,"cts":false,"x":510,"y":160,"wires":[]},{"id":"8b1db693.daf448","type":"ui_group","z":"","name":"Ofiicinas","tab":"ef7098ce.c64e78","order":1,"disp":true,"width":"25","collapse":false},{"id":"ef7098ce.c64e78","type":"ui_tab","z":"","name":"Federico","icon":"track_changes","order":1,"disabled":false,"hidden":false}]

The question is that what I would like is to find a way that every 10 seconds a ping is made to each of the hosts and, depending on the answer, to complete the fields in the table.

I don't know if I can make myself understood. Could you give me some help in this regard or at least tell me what path should I take? I searched the internet but I did not find anything similar, I found something at Monitoring IoT by Ping but it does not work for me.

Thanks everyone for your help!
Sorry for my English, it is not very good.

This IP addressing cannot really function at all, you have multiple machines with the same IP address. Have you maybe made a mistake while writting this down?

Sorry !!! .... I did abuse of "copy and paste" and avoid modifying the ip

these are the correct directions

Office 1:
- printer: 192.168.1.11
- pc 1: 192.168.1.12
- pc 2: 192.168.1.13
- pc 3: 192.168.1.14

Office 2:
- printer: 192.168.2.11
- pc 1: 192.168.2.12
- pc 2: 192.168.2.13
- pc 3: 192.168.2.14

Office 3:
- printer: 192.168.3.11
- pc 1: 192.168.3.12
- pc 2: 192.168.3.13
- pc 3: 192.168.3.14

Office 4:
- printer: 192.168.4.11
- pc 1: 192.168.4.12
- pc 2: 192.168.4.13
- pc 3: 192.168.4.14

I thought so!
Your English is fine!

What doesn't work? Show us a screenshot of your flow and where you enter the IP addresses.

Ah, just saw that the flow you wanted to post is missing in your first post!

I already uploaded it, I had copied the code from only one node. it's OK now

this is the ip:

[ {"name":"router","host":"192.168.0.1"}, 
{"name":"cel fede","host":"192.168.0.3"}, 
{"name":"chromecast","host":"192.168.0.4"}, 
{"name":"DESKTOP-BU4OE2S","host":"192.168.0.5"}, 
{"name":"desconocido","host":"192.168.0.9"}, 
{"name":"android","host":"192.168.0.11"}, 
{"name":"raspberry","host":"192.168.0.21"}, 
{"name":"DESKTOP-Q5EN2V","host":"192.168.0.38"}, 
{"name":"virtual","host":"192.168.0.13"} ]

and here are the screenshots

the flow you posted is ...

that is nothing like the screen shot of your flow.

That's right, as what was published in https://discourse.nodered.org/t/monitoring-iot-by-ping/23718/28 did not work, I decided to start from 0 with a new one.

The caption I uploaded is from when I tried the code from Monitoring IoT by Ping.

12

ok, im lost off with which one you are trying to get working - the flow you posted has no pinging etc.

the flow from the Monitoring IoT thread had a small typo (pretty easy to fix - i'll go edit the post in a second)

here is the fixed version...

Ohhh yes now go, my apologies but the truth I could not find the typographical error.

With this arrangement that you made, I will try to continue advancing and I will tell you how I am doing. Thank you!
