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.

1. SolarWinds Engineer’s Toolset (FREE TRIAL)

SolarWinds Engineers ToolsetFirst 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.
