durations

Durations: for

for makes a watch raise only when its condition holds for a while. Here, the response time of a page: slow for three passes, very slow for ten minutes.

How to read it

• 'for' => '3 runs': the condition holds at this pass and the two before. One slow pass alone raises nothing.
• 'for' => '10 min': the condition holds at every pass for at least ten minutes, whatever the interval of the probe.
• A duration is a whole number from 1 to 10 000, a blank, a unit: s, min, h, d for a time, 30 days at most; run or runs for passes, in for only. Without for, '1 run': the watch raises at once.
• A pass where the condition does not hold, or where the value is missing, makes the count start again.
• for exists on above, below, deviate, state and expect. The other durations are window of increase, the thresholds of silence, ahead of above and below, and the duration setting of a custom.

To adapt it

• $answer['time'] is in milliseconds, connection included.
