Memory Usage? 1

[parkers]

I currently administor a RedHat Linux v7.2 server which currently runs the following:

apache web server (max 10 servers, with 20 spare)
perl, sendmail, HTML
MySQL database server

Now, the usage of this server is not huge, the database is relatively compact too however I am sitting at 97% memory usage (of a total of 768MB) ... looking at the running processes then there would not be anything unexpected running like a broken script. Performance wise it seems OK for now.

I was wondering if there are any commands to do the following:

* check memory usage for running apps
* re-allocate or free up resource

Any help would be appreciated.

Thanks,
SP

For memory usage you can take a look at man sar

Hope This Help, PH.

Hi ... thanks for the quick reply ... unfortunately I do not have sar installed ... and subsequently any man pages. I assume this is available as an rpm

any other ideas?

top might also be a useful command.
