List of Matches


The Value match matches value lists by the actual values they contain, using minimum and maximum thresholds. If the value list contains multiple values (data sources), you can select whether all or any data sources need to match for a successful match. This match is usually used in conjunction with the RegEx match.

This match only works with the values converted to a rate. If you match network traffic, for example, which is usually provided as a counter value, this match will not work with the actual (integer) counter value, but with the rate, the change over time. (Academics like to call this the time differential.) The conversion is done using the global value cache. (Academics: Finite difference. ;) Using this match in the PreCache chain therefore only works reliably for gauge values! See Chains#Pre- and post-cache chains for details.
