How PRTG CPU load monitoring works

The processor (central processing unit - CPU) processes incoming application commands. A processor chip usually contains several processor cores which share the overall load. This makes for improved stability and performance.

During CPU load monitoring, the current computing power is provided as a percentage. As the computing power that is needed for active processes rises, so does the CPU load percentage. But the more processor cores your CPU has, the less each of these cores will be strained. As a result, the CPU load will be lower. With PRTG, you can monitor both the overall processor load as well as the loads of individual CPU cores.

Because CPU requirements can skyrocket quickly (go ahead and install a new application in your network for a demonstration) and are a fundamental consideration when optimizing the performance of your system, these requirements should be monitored thoroughly, especially in a critical IT infrastructure. PRTG CPU load monitoring is compatible with both Windows and Linux/Unix-based systems. PRTG uses SNMP to read the CPU loads of devices made by a variety of different manufacturers. You can also use WMI for Windows systems, and revert to SSH for Linux-based devices or OSX computers.

Feel free to choose the monitoring technology that works best for your particular IT infrastructure and situation.

CPU monitoring:
PRTG provides for a balanced load


Uniform load distribution

Uniform load distribution

Stable servers ensure a company’s countless business processes run properly. But for servers to be stable, CPU computing power must be distributed evenly and not exceed a certain level. This is also important for computers and any other processor-controlled hardware. If the CPU load is too high on an application server, for example, then it will slow down the reaction times of the corresponding applications and can even put the system at risk of crashing. The result: Idle coworkers, dissatisfaction, and decreasing work productivity due to work processes in the entire firm becoming slower and slower.

CPU load monitoring quickly sounds the alarm

CPU load monitoring quickly sounds the alarm

PRTG CPU load monitoring will show you exactly where the load is distributed, and how much is placed on your servers. If the values get too high, you’ll immediately receive an alert. You can also track the evolution of CPU load over the course of several weeks or months. By doing so, you will allow yourself to act quickly and minimize the risk of being caught off guard in the future. With continual CPU load monitoring, computing processes can be distributed equally, and speed and performance optimized. Your business will run smoothly, without frustrating delays in business applications or costly system downtime.

With PRTG, everyone will work with peace of mind.


4 good reasons to choose PRTG as your CPU load monitoring tool

Ensure the server doesn’t come to a halt

Ensure the server doesn’t come to a halt

Using too much (or all) of the server CPU can lead to a significant dip in performance, and in extreme cases, to the server actually crashing. With CPU load monitoring that tracks the load over the long term, you can quickly go about redistributing the load or upgrading hardware to avoid situations which could have serious consequences for your business. Should the CPU load suddenly reach critical levels, such as during the installation of a new application, you will notice the spike immediately and can pull the emergency brake before any damage is done.

Allow applications to react quickly

Allow applications to react quickly

A load that is distributed evenly and at appropriate levels lets businesses do away with unneeded hardware updates and the hassle of having to struggle with slow business applications. Work time and computing capacities therefore do not go to waste. In other words, CPU load monitoring helps your company save money.

Be alerted immediately

Be alerted immediately

PRTG alerts you automatically: simply set a CPU load threshold value for the system you are monitoring, and PRTG will automatically send you an alarm via SMS, email, or push notification if the defined percentage is reached.

Maintain an overview
