This is my first post (yes I'm a newbie)....

I'm looking for a list of Linux and Unix commands for performance monitoring and a good sight or area on this site that would have man pages and or information on those commands.....

Thanks if anyone can take the time to post.....

Probably the most useful and widely available realtime performance monitoring tool (for the CLI, anyway) is the 'top' command. For remote/non shell-based monitoring I suggest looking into MRTG, which can do much much more than just monitor network traffic.

don't forget vmstat and sar:

$ vmstat
procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu----
r b swpd free buff cache si so bi bo in cs us sy id wa
1 0 124 582056 6676 294924 0 0 3 4 9 14 0 0 99 0

$ sar 1 1
Linux 2.6.9-22.ELsmp (mybox.home.com) 01/12/2006

10:00:00 AM CPU %user %nice %system %iowait %idle
10:00:01 AM all 0.00 0.00 0.50 0.00 99.50
Average: all 0.00 0.00 0.50 0.00 99.50

do a man on both for addiitonal info,
manny

Thanks....

I've been looking at both top and vmstat....

I'm also looking at 'linmon' but I'm not familiar with it at all....

Edit: Hmmmmm the doc I have says theres a man page on it but there isn't one on the system I'm on....

You can use vmstat, sar and top (linux only) for process monitoring.. or you could also write a script base on the commands mentioned above.

how about Solaris equivalent of 'netstat -i 3' and 'iostat -xntcz 3' on Linux?
any idea?

Hi

I've just installed collectl, it seems to be very useful tool, by the way. But I'm afraid there is a problem when I try to dump the information into a file, collectl can not compress the information, and I think it should be able to, since I got Zlib installed. This is the warning displayed out:

Zlib not installed so not compressing file(s). Use -oz to get rid of this warning.

I do not how to solve this problem. Thanks.
