Hi all,

is there a simple tool to monitor high system loads and outages in debian?

For me, it would be completely sufficient if there would be a tool
that samples every minute or every few minutes (e.g. in a cron job)
the system load and reports any issues to the user in a simple way
like this:

day > load 5 | > load 10 | > load 15 | DOWN
------------------------+-------------+-------------+----------
26.01. 6.31% | 1.20% | 0.53% | 0.00%
27.01. 6.31% | 1.20% | 0.53% | 0.00%
28.01. 6.31% | 1.20% | 0.53% | 0.00%
29.01. 6.31% | 1.20% | 0.53% | 4.43%
30.01. 6.31% | 1.20% | 0.53% | 0.00%
------------------------+-------------+-------------+----------
Average: 6.31% | 1.20% | 0.53% | 1.31%

Purpose is to get an overview about the "performance" of the server
provider in case of "sandbox" vservers, so where I would not be aware
of any issues like the server is not available some hours during
nighttime for example.

I have started writing such a program in perl, it works great but
monitors only real downtimes at the moment, so not by system load as
the figure above indicates.

Best regards,
Joerg

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 :-)

Years ago, I wrote my own.

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

Interesting. And it's all in Sid too :-)
