Smokeping::matchers::base – Base Class for implementing SmokePing Matchers OverviewThis is the base class for writing SmokePing matchers. Every matcher must inherit from the base class and provide it’s own methods for the ‘business’ logic. Note that the actual matchers must have at least one capital letter in their name, to differentiate them from the base…
Smokeping::matchers::Medratio – detect changes in the latency median OverviewThe Medratio matcher establishes a historic median latency over several measurement rounds. It compares this median, against a second median latency value again build over several rounds of measurement. By looking at the median value this matcher is largly imune against spikes and will only react to…
Smokeping::matchers::Median – Find persistant changes in latency OverviewThe idea behind this matcher is to find sustained changes in latency. The median matcher takes a number of past median latencies. It splits the latencies into two groups (old and new) and again finds the median for each groups. If the difference between the two medians is…
Smokeping::matchers::ExpLoss – exponential weighting matcher for packet loss with RMON-like thresholds DescriptionMatch against exponential weighted average of last samples, thus new values are more valuable as old ones. Two thresholds – rising and falling – produce hysteresis loop like in RMON alert subsystem. If the average reaches the “rising” threshold, matcher go to the “match”…
