Hello all,

Has anyone used "Atop" or "collectl" monitoring tool before. I have installed it and the logs are recorded under /var/log/atop and /var/log/collectl. Is it good for monitoring the CPU load related issues? I feel "atop" is good for the performance related issues.

Need your suggestions

Frankly, I've not heard of atop before. I think top and htop are much more common.

I found some pretty good reviews with a web search.

If indeed it logs its output, I can see that it might be quite useful, as neither top nor htop do so. It's in Debian repos and I just installed it to my Debian box. I'll take a look at its output tomorrow.

Update, the next day:

I took a quick look at atop this evening. If you run it from the command line, it looks a lot like htop, though it's arranged differently. The logs, though, seem to binary, so I'm going to have to read the man page a bit to learn how to read them.

I have installed it and its good for monitoring performance related issues as the logs are recorded and can be viewed later even when there are problems

I am thinking to keep logs for about 10days. Unfortunately i donot know where to set the option

Haven't used collectl in awhile, however http://collectl.sourceforge.net/Performance.html may assist you in your quest.
It is Very Comprehensive.
atop I've never used.
