[Project Title]
"Enhancements to the Integrated SNMP Monitoring in the FreeBSD Operating System",
part of the "Fully Integrated SNMP Monitoring" idea for the FreeBSD project.


[Synopsis]
Implement a module for the BSNMP daemon which provides information as defined
in the EtherLike-MIB (RFC-3635), and also design and implement an extension to
the HOST-RESOURCES-MIB (RFC-1540 and RFC-2790).  Both enhancements will be
implemented as modules to the BSNMP daemon, in the C language.


[Benefits to the FreeBSD Community]
Although there are others implementations of SNMP daemons, BSNMP development
focuses, even unintentionally, the FreeBSD Operating System.  Thus, extensions
and improvements to it will surely have a positive impact mainly for system and
network administrators managing FreeBSD hosts.  Interoperability with others
implementations is ensured by the SNMP protocol.

EtherLike-MIB provides important information about the underlying network
infrastructure to system and network administrators.  The proposed extension
to the HOST-RESOURCE-MIB, combined with EtherLike-MIB, enable these
professionals to better monitor and manage their network environment.  SNMP is
very well suited for remote management, and also an open standard published by
the IETF.


[Deliverables]
* Functional implementation for the EtherLike-MIB (IETF RFC 3635), in the C
  Language, as a module for the BSNMP daemon.  Must compile and run under a
  FreeBSD 6-STABLE and 7-CURRENT.
* Creation and implementation of an additional MIB which will extend and provide
  additional data when compared to current HOST-RESOURCES-MIB standard.  Also,
  must compile and run under FreeBSD 6-STABLE and 7-CURRENT.


[Project Details] 
Extensions to the BSNMP daemon are in form of modules, which implement certain
functionalities, using the C language.  These modules are accessed when queries
ask for data they provide, having them to poll the operating system on their
behalf.

The EtherLike-MIB is a proposed standard, approved by the IETF as RFC-3635. Its
implementation must follow the guidelines described in the RFC.  The data
provided by this module will be polled from the respective interface driver
(e.g.: xl driver for a 3com NIC) and returned to the querier.

The extension to the HOST-RESOURCES-MIB require two steps: first the design and
creation of a MIB, named DISKSTORAGE-MIB, that will describe what information
will be available; second is the implementation itself of this MIB.  Although
portions of the information may be obtained through the HOST-RESOURCES-MIB,
this MIB will provide much more detailed and complete information.  This
includes informative data equivalent as provided by lsvfs(1), mount(8),
nfsstat(1), and dumpfs(8) commands.
