<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Sorry for the top post earlier, I'm not used to sending email from my<br>
phone. I wanted to take a minute to follow up and further tout the<br>
virtues of atop.<br>
<br>
When your performance monitoring system (be it collectd, xymon, opennms,<br>
or whatever) tells you there's a problem with a server, atop is what you<br>
want to use when you log in to find the problem. It has completely<br>
displaced my use of the sysstat suite of tools. It presents all the<br>
information you could get from sar and pidstat from within the friendly<br>
interface of top. You can view cpu, memory, i/o, and network statistics<br>
at the system and per-process level. You can do this in real time or you<br>
can step through samples recorded earlier. The next time a user<br>
complains about how things were "slow" the day before, you'll be able
to<br>
go back and pinpoint exactly what was happening. Although the<br>
interactive interface is what really shines, if you still need sar style<br>
reports there's atopsar.<br>
<br>
The lwn article I linked to earlier is a great overview of what you can<br>
do with atop. For a more limited but in depth example of using atop this<br>
paper [0] is good. It's also worth reading because the beginning is a<br>
good refresher on virtual memory and the end presents a good use case<br>
for cgroups.<br>
