How check health & performance of a Linux Server (Web Server) ?
Posted on 2015-02-06
Hi all -
I am having sporadic problems with my Linux/Apache Web Server (It is a dedicated Server, CentOS 5.6, and I have root access). Sometimes it appears that MySql is the culprit; other times Postfix. At other times I am told that it was a "stuck" process running, other times the Sun Spots get blamed ;)
I want to be able to tell when my server is running normally, and when it is not, to help pinpoint exactly what is causing the problem. This means that I want to check it often, many times per day, so trying to avoid command-line checking. Is there a software utility or service that checks these kind of things?
Thanks in advance
