Perhaps something SNMP-based?

Hmm I have briefly looked at that now, but it seems to be quite an
overkill for what I want to archieve, or am I wrong?
For system traffic monitoring I use "vnstat" at the moment, which is a
very small and very easy to install and use. I am looking ideally for
something as easy as that :-)

first graphic. It's an app. that records various things every 5 minutes
in a db. When there is nothing in the db. the system is down.

Parse this single line file: /proc/loadavg.

Thats what I already do in the perl program I wrote, in order to get
the latest load (first number is the average per 1 minute)... Is there
anything else you want to tell me, something that I missed?
Anyway, it seems that there is not such a tool. cacti and snmp seem to
be complex, the program from Hugo seems to be for a slightly different
purpose. All are not command line oriented.
QUESTION FOR ALL OF YOU:
Would anyone find it benefitial for them what I have in my mind (see
first email)? If yes, I would continue work and try to put together a
debian package one day.
Best regards,
Joerg

Oh, sorry. When you wrote /monitors *only* real downtimes at the
moment/ I though you meant that it did not yet track system load.

Other than that your mother dresses you funny? Nope. :P
Seriously, though, I'd insert the records into an SQLite database,
so that you can create all sorts of trend reports.

i'd suggest RRD (round robin database) - see the rrdtool package. with any
other databases, you have to deal with data accumulation over years of usage.
with RRD, it keeps averages where you get detailed info for the present, and
less detailed but still useful data for anytime in the past (well, for a
reasonable re-definition of 'anytime'). and the file size is always constant.
i have all kinds of performance data for the past 3-4 years yet i don't have
to worry about archiving old data or overflowing or ending up with
garguantian data files.
