When it comes to monitoring the diverse and complex environments found within modern Web applications, there are several metrics that must be monitored. This monitoring ensures full functionality within the code and user-interface levels of an application infrastructure. Even though the specific metrics you decide to monitor is dependent on application function and architecture, choosing to monitor select system metrics ensures stability within enterprise hardware components. The following system metrics should be continuously monitored to reduce application errors and subpar performance.
Disk Usage Rates
When it comes to the various issues and reasons why an application under-performs, one of the most common hardware causes is a lack of available disk space. Did you know most of the speed attributed to a Web application is based upon the functionality of the disk. As a general rule of thumb, the faster a hard disk is able to handle data, the faster your application will perform. However, it’s the amount of available disk space that supports the overall performance of your hard disk. The more crowded a disk, the slower it performs. Not only does high disk usage destroy the performance of an application, but it can also create security vulnerabilities due to various, fragmented blocks of data being sent to multiple areas within the drivers.
If you were to think about your hardware components as a human, the CPU would be its brain. CPU, an acronym for Central Processing Unit, oversees the operation of all programs. Through a series of complex logical and arithmetical operations, the functionality of an entire network is based upon the performance of its CPU. Factors such as application usage determine the overall functionality of this component. Therefore, it’s essential to monitor the health and events within a CPU. When using a free web application monitoring service, you can determine the precise needs for your server, allowing CPU resources and various allocations to be adjusted to accommodate peak usage periods.
Physical Memory Usage
Also referred to as RAM, or Random Access Memory, this component acts as a temporary storage space. This is where frequently accessed data is stored, which enhances the speed and performance of programs as they’re loaded from this point before being accessed by the system CPU. To look at system loads and other various on-page elements, you can use a program like Every-Step, or choose from another one of the available options if you need something more capable.
As a general rule of thumb, the greater your physical memory space, the faster your entire network will perform. Therefore, the majority of development experts suggests adding as much physical memory space as possible by your system. This reduces the occurrence known as a swap space, which is when stored files are switched to another resource as the physical memory usage becomes full. This action typically results in severe performance issues, some of which may be critical if it occurs during high-usage moments.
