mackerel-plugin-sample.php

<?php
$time = time();
$value = rand(5, 50);
$value1 = rand(5, 50);
$value2 = rand(5, 50);
$value3 = rand(5, 50);
$metric_name = 'random.count';

echo "{$metric_name}\t{$value}\t{$time}\n";
echo "{$metric_name}_1\t{$value1}\t{$time}\n";
echo "{$metric_name}_2\t{$value2}\t{$time}\n";
echo "{$metric_name}_3\t{$value3}\t{$time}\n";
