第9章 $fh.stats

一時統計カウンターとタイマーを利用します。これらは Studio でグラフとして表示できます。

9.1. 例

// Increment a counter.
// The name for the counter you want to increment.
// If this doesn't exist, it is created, and starts at 0.
var counter = 'my_counter';
$fh.stats.inc(counter);

// Decrement a counter
$fh.stats.dec(counter);

// Record a timer value
// The name for the timer you want to record a value for.
// If it doesn't exist, it is created.
var timer_name = 'my_timer';
// Timing in milliseconds of the interval you wish to record
// (for example, time difference between a timer start and end)
var time_in_ms = 500;
$fh.stats.timing(timer_name, time_in_ms);
