Hi,
Im fairly new to programming in python, and have a question.
Im looking to build a program that monitor's certain things on my Linux
system. for instance disk space. What is the best way to monitor a Linux
server without using to much resources?
Should I execute shell commands and grab the output of them? Or should i use
SNMP. Or is there a better way?
Thanks in advance!

de Haan:
I'm guessing from the text of your message that this is a single,
stand-alone system. Nagios and cacti are complete overkill for system
monitoring on a single machine. Here are some other options that you
can try:
More options are good, but de Haan describes it as a Linux *server*, not
desktop. In any case, some people might disagree that nagios is overkill
-- it depends on what you want to monitor.
* GUI monitoring - gkrellm is great for this. You can run it and see
performance graphs and monitors right in a little app on your desktop.
I've used that. I can't say it excited me too much.
Here's a quickie that I built for a client, it watches the 15 minute
load average.
[...]
Your script appears to mix tabs and spaces for indentation. Either that
or Thunderbird is playing silly buggers. Specifically:
for line in open('/proc/loadavg'):
#If the load average is above threshhold, send alert
loadav = float(line.split()[2])
if loadav < threshhold:
print '15 minute load average is '+str(loadav)+': OK!'
else:
print '15 minute load average is '+str(loadav)+': HIGH!'
sendMail()
Note the inconsistent indent at the end.
