This module matches packets based on some statistic condition. It supports two distinct modes settable with the \fB\-\-mode\fP option. .PP Supported options: .TP \fB\-\-mode\fP \fImode\fP Set the matching mode of the matching rule, supported modes are .B random and .B nth. .TP [\fB!\fP] \fB\-\-probability\fP \fIp\fP Set the probability for a packet to be randomly matched. It only works with the \fBrandom\fP mode. \fIp\fP must be within 0.0 and 1.0. The supported granularity is in 1/2147483648th increments. .TP [\fB!\fP] \fB\-\-every\fP \fIn\fP Match one packet every nth packet. It works only with the .B nth mode (see also the \fB\-\-packet\fP option). .TP \fB\-\-packet\fP \fIp\fP Set the initial counter value (0 <= p <= n\-1, default 0) for the .B nth mode.
