Channel monitoring system?

Question

.NET

Guys, after spending about an hour in Google searching for information on the topic of monitoring, I did not find anything suitable for me. Tell me please.
Interested in a system that could download a file and measure the speed during the day - two every 5 - 10 minutes. And also check the availability and ping of the site every minute. those. so to speak active monitoring of the channel.
Let me know if anyone knows.

Answer 1

xymon + a couple of plugins to write.
This is how I monitor a large number of servers for download speed.

Answer 2

I monitor the channel with zabbix, or rather the availability of the provider's gateway, through the UserParameter.

#!/bin/bash
wrst=$(mtr -r -c $1 $2 | grep -v HOST | tail -n 1 | awk '{ print ($8) }');wrst=${wrst:-"-1.0"};echo $wrst;

Response - the worst response time, -1 - the channel is down.

Answer 3

Munin, there is a ready-made plugin for ping (ping_* checks every 5 minutes, plots the response time), there is also a ready-made plugin for checking page load time via http (http_loadtime) put on your server and monitor

Answer 4

Thanks everyone for the advice. But still I decided that it's easier to sketch a small script.
If anyone needs it, use:
Upload the file to the test server, in my case it is 100mb.bin
and test from another server: Topic closed! Thanks to all!
<?php
function getDownloadSpeed($serverAddress) {
$tempfile = '/tmp/100mb.bin-'.time();
exec('wget http://'.$serverAddress.'/100mb.bin?a='.time().' -O '.$tempfile. ' ~ 2>&1', $out);
unlink($tempfile);
foreach($out as $line) {
if (preg_match('#[\d:\s-]+\((.*?)\).*?saved#', $line, $matches)) {
return $matches[1];
}
}
}
function getPing($ip=NULL) {
$exec = exec("ping -c 3 -s 64 -t 64 ".$ip);
$array = explode("/", end(explode("=", $exec )) );
return ceil($array[1]) . 'ms';
}
function testServer($serverAddress)
{
$ping = getPing($serverAddress);
$download = getDownloadSpeed($serverAddress);
echo "Ping test: ".$ping."\n";
echo "Download speed test: ".getDownloadSpeed($serverAddress)."\n";
file_put_contents('test-vps-'.$serverAddress.'.log', date('d.m.Y H:i:s').'|'.$ping.'|'.$download."\n", FILE_APPEND);
}
testServer('server_ip');
