# Smokeping::matchers::CheckLatency(3)

Edge triggered alert to check latency is under a value for x number of samples

## NAME

Smokeping::matchers::CheckLatency - Edge triggered alert to check latency is under a value for x number of samples

## DESCRIPTION

Call the matcher with the following sequence:

```
 type = matcher
 edgetrigger = yes
 pattern =  CheckLatency(l=>latency to check against,x=>num samples required for a match)
```

This will create a matcher which checks for "l" latency or greater over "x" samples before raising,  and will hold the alert until "x" samples under "l" before clearing
