Warnings tooltips in Finder (classic)

Nexthink Finder is a Windows-only desktop application whose functionality is now available within the Nexthink web interface. Nexthink can now be used directly from a browser and most functions no longer require an additional desktop application.

High CPU usage

Applies to platforms | Windows | macOS |  

High device CPU usage

Applies to platforms | Windows | macOS |  

High device CPU usage

The tooltip displays the CPU usage on the device during a time interval when the overall CPU usage is above 70%. The tooltip appears in two forms:

  • When multiple applications are the cause of the high CPU load in the device and none is specifically responsible for it, the tooltip only displays a figure of the total CPU usage.

  • When a few particular applications have a significant impact on the CPU load, the tooltip details these applications and their CPU usage per thread, in addition to the overall CPU usage in the device. CPU usage per thread is not the same as overall CPU usage and is explained in further detail in the tooltip below.

The Collector takes a CPU load sample every 30 seconds and reports it every 5 minutes. To report high CPU usage, two or more consecutive samples must exceed 70% of the CPU usage. The reported value corresponds to the average value of the samples above 70%.

High application CPU usage

Applies to platforms | Windows | macOS |  


High application CPU usage

The tooltip displays a list of the processes (and their corresponding application) that consumed more than 50% of the CPU processing power per thread (40% for the system process) for at least 30 seconds during the selected time interval. Processes are ordered in the list by their contribution to the CPU load from the most to the least demanding.

A 100% usage corresponds to the capacity of a single-core single-threaded CPU. You can get more than 100% usage in CPUs with multi-core or hyper-threading technologies:

  • For each additional physical core in the CPU you get 100% more processing power. For example, the capacity of a dual-core CPU is 200%, for a quad-core 400%, for a hex-core 600%, and so on.

  • If the CPU uses hyper-threading technology, the processing power of each physical core is doubled. A hyper-threaded dual-core CPU yields 400% capacity, a quad-core 800%, a hex-core 1200%, and so on.

Note that this way of measuring is different from that of high CPU usage on the device. In this measurement, the overall capacity of a CPU is 100%, regardless of the number of cores and threads in the CPU. For this reason, the bottom of the tooltip displays the capacity of the CPU in terms of hardware threads, which can be, and usually is, bigger than 100%.

High memory

Applies to platforms | Windows | macOS |  


High memory tooltip

The tooltip displays the usage of physical memory when more than 70% of the total physical memory is in use for at least 5 minutes. It lists the top five processes that consume more than 1% of the total memory.

High IO throughput

Applies to platform | Windows |  

Single High IO throughput tooltip

Applies to platform | Windows |  

Multiple High IO throughput tooltip

A warning appears when IO operations exchange information at a rate higher than 20 MB/s for a period of at least 30 seconds.

The total IO throughput includes all the bytes transferred during read, write or any other kind of IO operation performed on either real or virtual peripherals, such as hard disks, flash drives, network controllers, keyboards, mice, etc.

High page faults

Applies to platform | Windows |  

Single high page faults tooltip

Applies to platform | Windows |  

Multiple high page faults tooltip

A warning appears when the device generates more than 5000 page faults per second in memory accesses over a period of at least 5 minutes.
