Intermapper
The InterMapper (see http://www.intermapper.com) is an
SNMP monitor that runs on the Mac platform. You configure it to
monitor a list of hosts using a basic ping test or a more informative
SNMP test -- SNMP "system" parameters can give information
about system uptime, operating system and much more. The InterMapper
does not, to the best of my knowledge, probe any of the more esoteric
SNMP parameters. At our site, we don't use SNMP alerts (those
are "alarms"), nor do we use SNMP to control systems.
While I don't know very much about SNMP, it was clear from
the outset that our InterMapper requirements were very modest indeed.
We have other systems where our SNMP monitoring requirements are
much more than those discussed here. We have backroom database systems
where we monitor the performance using a vendor-provided utility
that "plugs into" the SNMP suite provided by Sun. A daemon
is provided that extends the Sun service by acting as a back-end
to the snmpdx daemon in the same way that the dmispd
and mibiisa do. It's pretty clear that for those systems
we cannot eliminate as many services. More work is required to determine
which components are required in that context. Nevertheless, we
recognize the backroom database server is the exceptional case.
Most servers require much less.
