William Metcalf 3b3f5816bf You spin me right round baby, right round like a rotating packet capture right round. Oh, also log file size counters are now uint64_t 14 years ago
Anoop Saldanha 3f1c4efceb Add new flags var to tm module. TMs can now set flags to identify special properties. Also use these to identify receive TMs 14 years ago
Anoop Saldanha a844eecb0e - Updated all runmodes to use synchronization points, right before each thread(slot function) tries to de-init the thread. - Main thread now first disables receive thread(s) before it kills receive and rest of the threads. 14 years ago
Victor Julien 820b0ded82 Add per packet profiling. 
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.

Stats per packet include:
 1) total ticks spent
 2) ticks spent per individual thread module
 3) "threading overhead" which is simply calculated by subtracting (2) of (1).

A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.

Code depends on --enable-profiling just like the rule profiling code.

New yaml parameters:

profiling:
  # packet profiling
  packets:

    # Profiling can be disabled here, but it will still have a
    # performance impact if compiled in.
    enabled: yes
    filename: packet_stats.log
    append: yes

    # per packet csv output
    csv:

      # Output can be disabled here, but it will still have a
      # performance impact if compiled in.
      enabled: no
      filename: packet_stats.csv

Example output of summary stats:

IP ver   Proto   cnt        min      max          avg

The proto 256 is a counter for handling of pseudo/tunnel packets.

William Metcalf 023a0f94a2 first stab at pcap logging no rotating buff etc 15 years ago
Gurvinder Singh 7d0781b349 added support to log dropped packet as netfilter logs while in inline mode 15 years ago

Anoop Saldanha 33f4beb0bc batching of packets support for cuda b2g mpm. Supported for both 32 and 64 bit platforms 16 years ago
Jason MacLulich 835630efbd Add initial support for reading packets from a DAG card, we only support reading from a single stream at this time. 
Use the --dag <dagname> cmd line option to specify from which DAG card to read pkts
from.

Issue at the moment with pkts being ejected during shutdown -- at the moment we
ignore any packets that are not of link type Ethernet.

Jason Ish 763fb4a583 Fix threading issues with unified-log. - Only write the header once, on opening, not per thread init. - Track the size in the log file ctx, not per thread. 16 years ago
Pierre Chifflier 4515ae13e4 Add Prelude output plugin 
Add support for reporting alerts to the Prelude SIEM system, using
libprelude to send IDMEF (RFC4765) messages.

Each message contains the alert description and reference (using
the SID/GID), and a normalized description (assessment, impact,
sources etc.)

libprelude handles the connection with the manager (collecting component),
spooling and sending the event asynchronously. It also offers transport
security (using TLS and trusted certificates) and reliability (events
are retransmitted if not sent successfully).

This modules requires a Prelude profile to work (see man prelude-admin
and the Prelude Handbook for help).
