Server / site status in the form of a traffic light / light bulb?

Question

Do it yourself

There was an idea to implement the availability status of the company's servers in the form of a physical light bulb / traffic light / display. For example available - lights up green. No, red.
What implementation methods do you know?

Answer 1

How would it be done in a large company:
We hire a painter, give him paint, he sits and listens to see if the server is working, as soon as it stops, he runs and repaints the light bulb.
Advantages of the method:
you can use ordinary 60 w light bulbs
easy integration and scaling
Cons:
response speed
Then you can gradually automate the project:
1 stage: painter (paints) + listener (listens and sends SMS to the painter). Seriously increase the response speed, but also the cost.
Stage 2: creating an SMS message template. It will also increase the response speed at no cost. You will need a specialist familiar with the phone OS to create a template, optimally attract outsourcing.
Stage 3. A mobile application that listens to the server through a microphone and sends SMS to the painter.
......
Stage 87. Arduino/rasberyPi

Answer 2

Arduino/STM32 + WiFi module?
Availability is checked by periodic ping/request

Answer 3

what about the meaning?
explain - where to place? in the IT workspace? (sometimes represented by one admin)... ..or
in the server room? - it makes even less sense to
push to a smartphone when ping (or another indicator of availability) is gone - here you can already report about 24/7
and it’s not a fact that it’s more difficult - if the servers are closed from a large network - ... but you anyway we need controlling nodes (or a mutual controlling service, in the background on each server) + a cloud application that, upon request from the "controller", sends a push
... this is, as it were, quite an initial level of mobile applications, but the efficiency is higher, and even more the question is what is more difficult
ps by the way yes (hello Roman Mirr ) there may be ready-made solutions ... that isin many ready-made solutions , there may be those that push alerts out of the box

Answer 4

Check out my article on the traffic light chrome extension.

Answer 5

Might be worth trying something like stm32 + wi-fi + led with a driver. MK connects to wi-fi and regularly pings or in some other way determines the availability of servers, then if the test fails, turn on the corresponding LED or lamp.

Answer 6

There is a complete software for monitoring the availability of services.
Nagios, Cacti, OpenNMS, Zabbix, Pandora FMS, etc.

Answer 7

And it's even easier to use the service that we recently released. There are colored lights and email notifications and you can check not only the server, but also the domain. You can organize a check from different parts of the world, view the history of checks and set the frequency of monitoring. The first month is free, but you need to register in the service https://panel.1cloud.ru/monitoring
