How to ping a server using Ajax in Laravel every 5 minutes? - ajax

Question

I have a HTML table full of server IP addresses, and I want to ping them them every 5 minutes to check if the server is alive (and eventually highlight table rows depending if the server is dead/alive).
Currently I'm using Ajax with a 5 minute interval which calls a method in my controller:
var checkSims = function() {
$.ajax({
type: "GET",
url: '/checkSimStatus',
success: function(msg) {
onlineSims = msg['online'];
offlineSims = msg['offline'];
console.log(onlineSims);
console.log(offlineSims);
},
error: function() {
console.log('false');
}
});
}
var interval = 1000 * 60 * 1; // where X is your every X minutes
setInterval(checkSims, interval);
However, this is not asynchronous and while this controller method is pinging the IPs the webserver cannot serve requests.
I've read about Laravel's queue system but I'm not sure this would suit me as I need one specific page to trigger the job, and would need to use JS to highlight table rows.

#f7n if you have done it with ajax, how will it work if that page where HTML table with IP address not open in a browser?
I think you must use cron job on a server. Also, if you use VPS (Linux) or something else you can write simple code with bash shell script and run it on the daemon. Also, you can create simple code like below, create php script where it will parse (grab) page with HTML table of IP addresses and ping server.
#!/bin/bash
echo "Press [CTRL+C] to stop.."
while true
do
php parse_and_ping.php
sleep 300
done
sleep 300 is mean, It will work every 5 minutes. Just save It on .sh file (run_shell.sh) and run It on a terminal or on the daemon of Linux server.
