Hi,

I'm looking for a solution to monitor cpu/disk usage on several servers and
it send me an email if there is an alert level reached.
BUT I'm looking for a autonomous solution, I don't want a centralized web
page interface who display status of all servers. I just need a program who
monitor the server processes and send alert by email. So, I don't want
Zabbix / Cacti / Nagios / XYmon / ZenOSS / Bijk...
I could code it by myself, but I want something more reliable...

I trough I could use webminstats plugin for Webmin, but I don't like Webmin
so much...

Any ideas ?

Have a look at MUNIN:

or MONIT: http://mmonit.com/

Why discard the option of using Nagios, or similar? How about just
running the Nagios daemon, configure notifications the way you want it,
and skip runnings its web gui?

If running the nagios daemon is not acceptable, one can use nagios
plugins like check_load and check_disk via cron. But first i'd give monit
a chance...

Wont even write to rrd's if you dont want it to, just alert you when
something goes over a threshold. Very light, modular, flexible.

I've seen monit. It provides a web interface which I don't need but why not.
I've found also "Mon".
Since those servers are standalone, in complete autonomy without a lot of
resources at all, I'm looking for a simple but reliable monitoring tool.

Thanks for your answers guys but I've received most of them directly, you have
sent to my email adress instead of ubuntu-server@lists.ubuntu.com, someone may
be interested by your answer too !

Thx !

I'm testing it. I've disabled rrd writes but I have errors in the
syslogs : Filter subsystem: Built-in target `write': Dispatching value
to all write plugins failed with status 2 (ENOENT). Most likely this
means you didn't load any write plugins.


By chance, do you know how to fix this issue?

Huh, never realised that it _needed_ a write plugin. Bit hacky but the
network communication is all UDP, so you could setup a network writer
to localhost which should hopefully keep it quiet.

you can do something else..
dont install nagios but use nagios plugins and nrpe.
you can also use snmp and a simple cronjobs on one centralized machine
that will check all the others every 510 minutes and will send the
results in a case of "warringcritical" state.

it's a piece pf cake to put it all together.
