HP MIBs
=======
HP Openview (and presumably more so with ITO clients), has an extensible MIB (Emanate). (This supplants the SUN master agent described below). On Openview systems see /var/opt/OV/share/snmp_mibs/Vendor/Hewlett-Packard/hp-unix.
This includes uptime/load averages, file systems. 

The Sun extensions MIB described below seems to interoperate with the HP/OV master agent.



Sun MIBs
========
Solaris recent versions have an SNMP agent delivered as part of the standard installation. It includes standard MIB-2 but is extensible too. See /var/snmp/mib. The standard extension is:-
SUN-EXTENSIONS-MIB /projects/mibmaster/009.Releases/MIB/SUN-EXTENSIONS-MIB
Includes the process table, including memory footprints, user, command, etc. There is an option through the MIB to send a signal to the process (whoa). Also there is basic uptime, page fault, network performance data system wide.


IETF MIBs
=========

RFC2790 : Host Resources MIB

It also includes the installed/running software, including arguments, state, CPU usage, memory footprint.

RFC2707/8 : Job Monitoring MIB
For print jobs.
