how to check memory usage ?
hello,

I have purchased VPS from one webhosting company. VPS comes with Virtuozzo power panel. It has 512MB gurranted RAM and dynamic RAM 2048 MB.

I have hosted single domain with 50MB database and wordpress installation.

But I am getting resource alerts. It goes sometime in yellow zone. I am not able to trace which thing is consuming more memory. My site has 3000 posts and 50,000 comments. is it because of that ? is it because of apache and mysql connections ? it is because of any plug-ins ?

how to trace that ? I have installed putty and typed "top" which is showing me following status at this time :

apache::qpsmtpd

Apache::Qpsmtpd(3pm)					User Contributed Perl Documentation				      Apache::Qpsmtpd(3pm)

NAME

       Apache::Qpsmtpd - a mod_perl-2 connection handler for qpsmtpd

SYNOPSIS

	 Listen 0.0.0.0:25 smtp
	 AcceptFilter smtp none
	 ## "smtp" and the AcceptFilter are required for Linux, FreeBSD
	 ## with apache >= 2.1.5, for others it doesn't hurt. See also
	 ## http://httpd.apache.org/docs/2.2/mod/core.html#acceptfilter
	 ## and http://httpd.apache.org/docs/2.2/mod/mpm_common.html#listen

	 LoadModule perl_module modules/mod_perl.so

	 <Perl>
	 use lib qw( /path/to/qpsmtpd/lib );
	 use Apache::Qpsmtpd;
	 $ENV{QPSMTPD_CONFIG} = "/path/to/qpsmtpd/config";
	 </Perl>

	 <VirtualHost _default_:25>
	 PerlModule Apache::Qpsmtpd
	 PerlProcessConnectionHandler Apache::Qpsmtpd
	 # can specify this in config/plugin_dirs if you wish:
	 PerlSetVar qpsmtpd.plugin_dirs /path/to/qpsmtpd/plugins
	 PerlSetVar qpsmtpd.loglevel 4
	 </VirtualHost>

DESCRIPTION

       This module implements a mod_perl/apache 2.0 connection handler that turns Apache into an SMTP server using Qpsmtpd.

       It also allows you to set single-valued config options (such as loglevel, as seen above) using "PerlSetVar" in httpd.conf.

       This module should be considered beta software as it is not yet widely tested. However it is currently the fastest way to run Qpsmtpd, so
       if performance is important to you then consider this module.

BUGS

       Probably a few. Make sure you test your plugins carefully.

       The Apache scoreboard (/server-status/) mostly works and shows connections, but could do with some enhancements specific to SMTP.

       Some credit goes to <mock@obscurity.org> for Apache::SMTP which gave me the inspiration to do this.
