The best CPU monitoring tools
CPU or central processing units need to be managed in the same way as any physical device in order to stay in operation. In this article we’re going to look at some of the best CPU monitoring software tools to see which is best for monitoring CPUs.
First up on this list we have SolarWinds Engineer’s Toolset which has its own CPU monitor and can monitor the maximum CPU load of connected devices. CPU load is displayed as graphs so that you can see if the CPU is declining over time. Graphs are particularly useful for seeing if there are viruses or any other issues that could be causing problems for a device.
To stop you from having to monitor everything yourself, SolarWinds Engineer’s Toolset has its own alarms feature. Alarms raise alerts whenever the defined thresholds have been reached. You can set metric thresholds for CPU load, so that once the load goes over this figure an alert is sent to you by email or SMS. This keeps you in touch with everything going on and makes sure that you don’t miss out on anything.
SolarWinds Engineer’s Toolset has its own autodiscovery feature which automatically discovers devices connected to your network. Once a device has been discovered you’re able to monitor its performance through metrics like CPU load and memory utilization. Using autodiscovery minimizes the amount of configuration time you need to spend configuring and updating the software.
No matter what size your organization, SolarWinds Engineer’s Toolset is a tool that provides one of the best CPU monitor products on the market. SolarWinds Engineer’s Toolset is available on Windows from a price of $1,495 (£1,146). You can also download a 14-day free trial.
Anyone familiar with Paessler PRTG Network Monitor will know that this tool offers one of the most complete CPU monitoring experiences on the market. With PRTG Network Monitor you can monitor Windows, Mac, and Linux devices for CPU performance issues. You can use this tool to measure key metrics like CPU utilization as a percentage and CPU utilization over time.
PRTG Network Monitor’s monitoring capabilities are driven by its sensors. There are many different sensors for CPU included within PRTG Network Monitor. These include the SNMP CPU Load Sensor, Windows CPU Load Sensor, Windows Process Sensor, SNMP Linux Load Average Sensor, and the SSH Load Average Sensor. The SNMP CPU load sensor shows the load of multiple CPUs as percentages over a time period of your choice (live, two days, 30 days, and 365 days).
You aren’t limited to tracking everything manually either. PRTG Network Monitor makes use of alerts to notify you by email and SMS once a threshold has been exceeded. So if CPU utilization exceeds the defined thresholds then you’ll be sent an alert to take action.
The price of PRTG Network Monitor depends on how many sensors you need to use. This starts with a freeware version that provides you with up to 100 sensors free of charge. The paid versions of PRTG Network Monitor start from $1,600 (£1,227) for 500 sensors. You can download a 30-day free trial.
Atera is a software package that supports managed service providers (MSPs). The platform is a cloud service so the MSP doesn’t have to install the monitoring software on its site. However, the remote systems that are being monitored do need to have agent software installed on them.
The Atera system is an RMM. That stands for “remote monitoring and management.” The monitoring part of that suite of tools includes the supervision of activities and statuses for networks, servers, and applications. The server monitoring functions of Atera include CPU monitoring. The service can watch the utilization of CPU and also keeps a record of the maximum CPU processing power that a server has.
The management functions of Atera include the ability to kill off abandoned processes that are chewing up CPU time. Other server maintenance utilities in Atera include the ability to clean disks, removing temporary files. It is also able to defrag disks. The service can create system restore points, back up servers, and restore saved files.
As Software-as-a-Service, Atera includes all of the software, processing, and storage facilities needed to run the platform. The service is charged for by subscription per technician per month. It is also possible to opt for a yearly subscription, which offers a lower rate.
The Atera platform is marketed as three editions: Pro, Growth, and Power. You can get a 30-day free trial of any of these versions to test it out.
4. StackPath Server Density
StackPath Server Density is a SaaS monitoring solution that has the ability to monitor CPU metrics like CPU load and CPU usage. Server Density provides you with the basic information needed to know when the CPU usage of a device is within acceptable parameters. This is easy to monitor from the perspective of the dashboard because of the simplicity of the design.
You can also define custom alert parameters. Server Density sends alerts via email, SMS, webhook, Slack, and Pagerduty. This ensures that no matter where you are, you don’t miss anything that could take a device down completely.
Overall, Server Density is a product that is suitable for networks of all sizes. The price of Server Density depends on how many servers you want to monitor. If you only need to monitor one server then you can pay as little as $10 (£7.67) per month. The next price point is two servers for $20 (£15.34) a month. The largest public price is $250 (£191.73) a month for 25 servers. You can contact the company directly about quotes for 25 plus servers. You can download a 14-day free trial of Server Density.
5. ManageEngine OpManager
A “best of” CPU monitoring tool list wouldn’t be complete without ManageEngine OpManager. ManageEngine OpManager is a network monitoring platform that lends well to CPU monitoring devices. You can use this program to monitor key metrics like CPU, memory, and disk utilization. If a PC or server has disk utilization that is too high you’ll be able to know about it very quickly.
There is a range of CPU metrics that can be accessed with ManageEngine OpManager. These include CPU utilization, CPU socket, CPU speed, idle time, PSU redundancy, user time, processor queue, and privileged time. This provides you with an in-depth CPU monitoring experience that goes beyond the basic CPU monitoring experience offered by most other competitors.
To make sure that you stay up-to-speed with all CPU performance concerns there is a notifications feature. You can configure thresholds for metrics CPU utilization so that you’re notified once a metric exceeds the configured parameter. If you want to cut back on unnecessary notifications then you can specify the number of times the metric must be violated before an alert is triggered.
ManageEngine OpManager can be purchased as the Essential version or the Enterprise version on Windows and Linux. The Essential version costs $715 (£548) and can be used on up to 25 devices. The Enterprise version is available for $19,975 (£15,317) and can be used on up to 500 devices. There is also a 30-day free trial.
Monitis is primarily known as a web performance monitoring platform that can also monitor the CPU. Monitis monitors CPU utilization to assess the health of individual devices within your network. You can also monitor other elements like memory, drive, load, and disk I/O for further details.
On Monitis you can configure your own alerts based on CPU utilization. You can do this by going to the Smart Agent Controller (which can be downloaded for Windows and Linux). Here you can add the server or device that you want to monitor. You can then enter the trigger values you want in the User and Kernel boxes. Once these limits have been exceeded, an alert will be raised.
It is worth noting that Monitis has been designed to start up quickly. Monitis claims that you can have this program up and running in less than 3 minutes without any installation. Being able to access Monitis online means that you aren’t restricted to one device when monitoring your network.

The amount you’ll pay depends on a variety of factors like uptime monitoring, real user monitoring, full page load monitors, servers, application monitors, sub accounts, and security monitors. You can download a 15-day free trial of Monitis.
SysGauge is a program that offers a narrower approach to CPU monitoring. With this product, you can monitor the CPU and memory usage of connected devices. In fact, SysGauge has its own GUI module called the CPU monitor. The CPU monitor can monitor CPU usage, CPU interrupt time, CPU interrupt rate, and CPU frequency. This is a considerable degree of depth for a smaller monitoring product.
In addition, SysGauge has also added an alerts system of its own. Users can set their own alert parameters and receive email notifications once a threshold has been crossed. If desired, the user can also execute custom commands to respond to events as they occur. This makes SysGauge suitable for responding to CPU performance issues within a live network environment.
There are three versions of SysGauge available; Free, Pro, and Ultimate. The Free version of SysGauge offers up to 10 counters, monitors and profiles free of charge. The Pro version offers 50 counters, monitors and profiles for $50 (£38). The Ultimate version offers 100 counters, monitors and profiles for $125 (£95). The free version of this product is an excellent choice for SMB’s.
SysGauge is available on Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, Windows Server 2003, Windows Server 2008, Windows Server 2012, Windows Server 2012 R2, and Windows Server 2016. You can download SysGauge.
Anyone familiar with application performance monitoring is almost certain to know about AppDynamics. AppDynamics is also a formidable CPU monitoring tool in its own right. Right off the bat, AppDynamics separates itself from the crowd on account of its autodiscovery feature. AppDynamics can autodiscover devices and applications in your network automatically.
Once configured, you can use AppDynamics to monitor the CPU utilization of all discovered devices at the infrastructure level. At the application level, you can also view metrics on process-specific CPUs. This gives you the depth needed to view the CPU performance of all devices in your network.
All of your usage is kept tabs on through the use of alert thresholds. AppDynamics’ alerts system makes use of artificial intelligence. Artificial intelligence is used to determine when CPU usage is consistent with anomalous behavior. Putting your threshold-based alerts in the hands of the AI system is beneficial because it cuts down on unnecessary alerts that you are often subjected to when a device’s CPU peaks unexpectedly.
There are three versions of AppDynamics that you can purchase; APM Pro, APM Advanced and APM Peak. Each of these offers CPU monitoring, but you’ll have to contact the sales team in order to view the prices. You can evaluate AppDynamics as a free trial download.
