Any tricks to find performance hogs on Linux webserver? (LAMPerl system)
Hi,
my webserver is getting permanently down/unreachable.
I know that most of my perl scripts running on the server have room for optimization. But they are diverse and I am not enought a linux pro to know how I can track/log which script exactly is the source of the problem.
I got perl-scripts which are invoked for every pageload
I got scripts which run under fcgi
And I got a few ones which require a connection to a local mysql server.
Is there a log which gives me more info about when the server's lights gone off and where the cause was/is? I am on dedicated but managed hosting and don't have much access to low level system-files (1&1). Any tactics, log-loops I can build into my system or the scripts to gather information about cpu cycles used, system load etc?
Any help appreciated...
