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.

try building an rpm from the src.rpm provided - collectl-2.4-2.src.rpm

this might shed some light on any missing dependencies you may have...

this is how I installed mine...looks promising.

thanks Mark

iostat is available on linux through the sysstat package.

Thank mr_manny.

everything is working out now!

Here I am again.

Everything was looking good workin with collectl, until I tried to unzip the .tab.gz file generated, I ran collectl this way:

collectl -i 5:5 -P -s cCdDmnNZ -ou -f /tmp/collectl

All the .gz files were generated correctly except the .tab.gz, it size is 10 Bytes, and if I try to unzip it the next message is displayed:

gunzip: collectl-atm117-20080129-141624.tab.gz: unexpected end of file

I think it might be something to do with the way to stop collectl (I'm using the TERM signal), maybe something to do with the Zlib libraries (but then, why the rest of the files are correctly generated?).

I'm afraid I need help again

Hi again!

all my troubles seem to be solved.

I remove all the zib perl libraries I had installed, and then I downloaded and installed the next one:

perl-Compress-Zlib-1.41-1.2.el4.rf.x86_64.rpm
(I'm working on Red Hat, I guess it would be the same for the rest distr)

And that's all!. (I hope)
