You can control sniffer at run-time and acquire status information by sending running sniffer process any of the supported signals. Signal can safely be sent to any of the running sniffer processes (threads).
list of supported signals
After receiving this signal, sniffer will immediatly start dumping packets it currently has in its buffer.
This signal will make sniffer output some statistical information to log file and/or (depending on command-line options) console. Information printed are: uptime (days, hours, minutes and seconds), size of the buffer (in kylobytes), number of packets currently in buffer, total number of packets that were buffered (including already dumped packets), total number of packets processed (including those that were ignored in on_receive_packet handler) and load average (in kylobytes per second and packets per second).
This sniffer enables debugging mode. For now, this only means memory allocation debugging, by using mtrace () mechanism. In short, all memory de/allocation will be logged to file which can be later analyzed for inconsistencies. This feature is available only on GNU systems; it should fail silently on non-GNU systems. Details are available in texinfo docs for libc, under memory allocation.
Disables debugging previously enabled with SIGINT1 signal.
