How does a website uptime monitor tool work?

miken · Oct 26, 2015

I want to know the process on how a tool works to monitor website uptime? Do I need to integrate it on my website system or it can do without verifications on my website?

Thanks

I imagine it just send pings at set intervals, when it receives no response back it assumes its down.

Via cron job.

Cronjob automatically check or send ping on every few minute, If connection failed then you will receive a email.

I have a .sh file which run on every 1 or 2 minute via cronjob and use if elseif command so If down then email will send and If not down then nothing will happen and simply process will end.

Hope you understand. There is many php based monitoring software is available.

They ping your domain at a set time interval and alert you if it doesn't respond with the appropriate response.

These tools are useful, but can also give false results.

The answer has been given indeed. It will test every X seconds if that certain page is still responding.

They have multiple means of monitoring your site. These companies can ping the server, they can even check your shopping cart to see if it works correctly. The way it works is they have servers (monitoring stations) located around the globe. Each server can either check your site at the same time or they usally rotate checking your site every X minutes. If one monitoring station checks your site and can't reach it, the next monitoring station has to confirm the failure before sending you a down alert.

There is nothing to integrate. You just give them the ip or domain and thats it.

As you give the software the IP

ORT, what it does is what your CMD PING command does, it checks response every 15mins or so, then records a percentage overtime of the availability of your site. Fairly basic
