| 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. |
