Error Log files @ high load

Hi,

my VPS was overloaded and inaccessible for some time and i want to ask for help in which log files i need to look, or which tools to setup to monitor and find the cause of repeated hig load?

watched:
/var/log/messages
/var/log/secure
/var/log/httpd/access_log
/var/log/httpd/error_log
/var/log/mysqld.log
/var/log/lfd.log (config server firewall)
/var/log/fail2ban.log

but found no excessive entries
during overload, i cant access server so cant lookup the proceses i think

NAME
Paranoid::Log::File - File Logging Functions VERSION
$Id: File.pm,v 0.83 2010/04/15 23:23:28 acorliss Exp $ SYNOPSIS
use Paranoid::Log; enableFacility('events', 'file', 'debug', '+', $filename); DESCRIPTION
This module logs messages to the log files, and is safe for use with forked children logging to the same files. Each child will open their own filehandles and use advisory locking for writes. This module should not be used directly, Paranoid::Log should be your exclusive interface for logging. SUBROUTINES
/METHODS NOTE: Given that this module is not intended to be used directly nothing is exported. init log remove dump DEPENDENCIES
o Fcntl o Paranoid::Debug o Paranoid::Filesystem o Paranoid::Input SEE ALSO
o Paranoid::Log BUGS AND LIMITATIONS
This isn't a high performance module when dealing with a high logging rate with high concurrency. This is due to the advisory locking requirement and the seeks to the end of the file with every message. This facility is intended as a kind of lowest-common demoninator for programs that need some kind of logging capability. AUTHOR
