Proprocessors alerts priority setting: how

[François Désarménien <francois () fdesar net>]

Hello,

I'm wondering how priority/classification are set up for preprocessors.

Looking at 'spp_portscan.c' I see nothing about it, but get it in the
alert file itself, like in:

05/23/01-17:52:39.161077  [**] spp_portscan: PORTSCAN DETECTED from xxx.xxx.xxx.xxx (STEALTH) [**] [Classification: 
Potentially Bad Traffic] [Priority: 2]

or

05/23/01-17:53:01.853464  [**] spp_portscan: PORTSCAN DETECTED from xxx.xxx.xxx.xxx (THRESHOLD 4 connections exceeded 
in 0 seconds) [**] [Classification: Attempted Information Leak] [Priority: 3]

How and where is it done ? Or is it a side effect (in the same alert file
some spp_portscan lines don't have priority) ?

Thank you,

François
