Low Level Logging
|
|
-----------------
|
|
|
|
Suricata's alert, protocol, and other types of output are built up
|
|
from a set of low level loggers. These loggers include:
|
|
|
|
- Packet logging (alerts)
|
|
- Flow logging
|
|
- Transaction logging (application layer)
|
|
- File information logging
|
|
- File data logging (file extraction)
|
|
- Statistics
|
|
|
|
These low level logging facilities are used to build up Suricata's
|
|
logging include EVE, but they can also be hooked into by plugins or
|
|
applications using Suricata as a library.
|
|
|
|
.. note:: At this time only a C API exists to hook into the low level
|
|
logging functions.
|
|
|
|
The Suricata source code contains an example plugin demonstrating how
|
|
to hook into some of these APIs. See
|
|
https://github.com/OISF/suricata/blob/master/examples/plugins/c-custom-loggers/custom-logger.c.

Packet Logging
|
|
~~~~~~~~~~~~~~
|
|
|
|
Packet loggers can be registered with the
|
|
``SCOutputRegisterPacketLogger`` function:
|
|
|
|
.. literalinclude:: ../../../../../src/output-packet.h
|
|
:language: c
|
|
:start-at: /** \brief Register a packet logger
|
|
:end-at: );
|
|
|
|
Flow Logging
|
|
~~~~~~~~~~~~
|
|
|
|
Flow loggers can be registered with the ``SCOutputRegisterFlowLogger``
|
|
function:
|
|
|
|
.. literalinclude:: ../../../../../src/output-flow.h
|
|
:language: c
|
|
:start-at: /** \brief Register a flow logger
|
|
:end-at: );
