Start with Admin Tools, Resource Monitor and let is run for a couple of hours. This will show you short term trends in CPU, Disk Usage, Network Usage and Memory Usage. This is probably the easiest tool to work with. <br />
<br />
You can also use Admin Tools, Performance Monitor. This is more advanced but you need to set up the data collection sets you want.

Intermittent resource usage problem

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

WordPress is a free and open-source content management system (CMS) based on PHP and MySQL for creating websites and blogs. Features include a plugin architecture, a template system and strong management, customization and search systems; through its dynamic presentation of content, webmasters have the flexibility to create websites easily.
