程式碼範例

範例 1

這個範例顯示整數平均值。

// This rule sets the outcome $size_mode to the average
// file size in the 5 minute match window.
events:
 $e.user.userid = $userid
match:
 $userid over 5m
outcome:
  $size_mode = window.avg($e.file.size) // yields 2.5 if the event file size values in the match window are 1, 2, 3 and 4

範例 2

這個範例顯示浮點數平均值。

events:
 $e.user.userid = $userid
match:
 $userid over 5m
outcome:
  $size_mode = window.avg($e.file.size) // yields 1.75 if the event file size values in the match window are 1.1 and 2.4

範例 3

負數輸入平均值

events:
 $e.user.userid = $userid
match:
 $userid over 5m
outcome:
  $size_mode = window.avg($e.file.size) // yields 0.6 if the event file size values in the match window are -1.1, 1.1, 0.0 and 2.4

範例 4

0 returns 0

events:
 $e.user.userid = $userid
match:
 $userid over 5m
outcome:
  $size_mode = window.avg($e.file.size) // yields 0 if the event file size values in the match window is 0

範例 5

忽略 0 個值

events:
 $e.user.userid = $userid
match:
 $userid over 5m
outcome:
  $size_mode = window.avg($e.file.size, true) // yields 394 if the event file size values in the match window are 0, 0, 0 and 394
