Hi,

Speaking of the stats that get output, what does "Outstanding" refer to?  See my stats below.

Packet I/O Totals:
Received:   5974738704
Analyzed:   5876466751 ( 98.355%)
Dropped:      8008319 (  0.134%)
Filtered:     98272389 (  1.645%)
Outstanding: 18446744073709551180 (308745620312.395%)
Injected:            0

You can issue the USR1 command to Snort.

Kill -usr1 (pidof snort) will dump the stats of the running Snort process to the output file (on redhat/fedora, /var/log/messages)

Hi there,

I need to get the amount of packet which have been dropped by snort.

I can get this when runing manualy snort (snort -n 100 -i eth0) in the stat summary after stoping snort (CTRL+C) like this :

.....
===============================================================================
Packet I/O Totals:
   Received:          100
   Analyzed:          100 (100.000%)
    Dropped:            0 (  0.000%)
   Filtered:            0 (  0.000%)
Outstanding:            0 (  0.000%)
   Injected:            0
===============================================================================
.....

Is there a way to get this information (dropped packets) in the /proc filesystem while snort is runing?

I did not found anything interesting after looking at /proc but maybe there is a preproc to activate or some tricks like this?

Thanks in advance,
Thibault
