      Used, Free, Wired, Compressed, Applications, Swap, Pages in/out

    • Disks

      Mounted Disks, Space Usage, Disk I/O, S.M.A.R.T status, Temperature

    • Battery

      Time remaining, Health, Watt, Temperature, Capacity, Age, Cycles

    • Networks

      Connected state, Public IP, Local IP, Mac-Address, Link Speed, Uploaded and Downloaded bytes

    • User Interface

      Carefully designed, Persistent User Interface, Color themes, Swipe to access on Macbooks

  • CPU

    CPU Usage is reported for the entire system. user is the amount of time the CPU was busy executing code in user space, sys the amount of time the CPU was busy executing code in kernel space and idle measures unused CPU capacity.

    The Load is a measure of the amount of computational work that a computer system performs. The Load Average represents the average system load over a period of time. The three numbers represent the system load during the last one-, five-, and fifteen-minute periods.

    System reports the number of processes and threads running on the system.

    The Thermal gauge represents the thermal state of the system. There are 4 thermal levels; normal, fair (fans running), serious and critical. The screenshot shows the indicator at the fair level.

    Top-3 List of Applications using most CPU. Click an App in the list to switch to that App. Open Activity Monitor by clicking its icon. CPU usage per App is presented normalized across all CPU cores (0-100%).

    The CPU model and current GPU model. The GPU model changes depending on if the system uses the integrated or the discrete GPU.

    Uptime is the time your computer has been working and available. Click the uptime label to see when your computer started, how long it has been at sleep and awake.

  • CPU
  • Memory
  • Memory

    Displays the memory usage of the system in a traditionally pie-chart. Wired memory is memory that is in active use and cannot be cached to disk. Active memory is memory that has recently been used or is in use by applications. Compressed memory is the amount of compressed memory in RAM. Free memory is memory not being used. Monit consider wired and active memory as memory in actual use.

    Top-3 List of Applications using most Memory (RAM). Click an App in the list to switch to that App. Open Activity Monitor by clicking its icon. The list shows Applications, not background processes.

    Physical Memory is the amount of RAM installed on your system. Cached Files is the size of files cached into unused memory to improve performance. Swap Used is the amount of space being used on your startup disk to swap unused files to and from RAM.

    Page Ins indicate how much data is being copied into RAM from the hard disk and Page Outs indicates how much data is being copied from RAM to the hard disk.

  • Disks

    Displays a list of all mounted disks. The first disk is the disk from which the system booted. This is also the disk the Disk gauge reports space usage for.

    Disk activity is displayed as a red and a blue triangle indicating the amount of bytes written and read from the disk per second.

    The horizontals line indicate disk usage in percentage. Below the line, you can see disk space used and space available.

    If your hard disk supports S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology), Monit will query the S.M.A.R.T. status of your disk and display a green square if the status is okay or a red square if your hard disk is failing. If S.M.A.R.T. is supported, we can usually also read the temperature of the hard disk. A grey square indicate that the disk does not support S.M.A.R.T.

    Click the disk icon to popup more details about the disk, including total bytes read and written since boot time.

  • Battery
  • Battery

    Displays the time remaining if the battery is discharging or the time until the battery is fully charged when connected to a power supply.

    Health is a comparison between your current battery capacity and the capacity when the battery was new.

    Condition describes the battery's health status. Normal means that battery is functioning normal. Replace Soon or Replace Now means that the battery holds (significantly) less charge than it did when it was new. Service Battery indicate that the battery isn’t functioning normal. You can continue to use your MacBook on a power adapter, but with this condition, you might want to consider replacing your battery.

    Batteries are expected to function for a certain number of cycles. A cycle is the sum of total and partial discharge cycles throughout the life of the battery.

  • Network

    If the computer is connected to the Internet, the Network circle is green, yellow if only connected to a local area network and red if there are no network connection.

    Your computer's Public IP address can be selected and copied.

    All active Network Interfaces are listed and the icon indicate if the connection is over Wi-Fi or Ethernet. If your computer is connected to a local network, the Local Address is displayed. The current upload and download rate is indicated with led lights. Total uploaded and downloaded is the number of bytes uploaded and downloaded since the computer started.

    Click the network icon to see a popup with more network information, such as the MAC address of the interface, the current Link Speed as well as the computer's Host Name, Router and DNS settings.

    A settings panel is provided by clicking the icon at the top-right corner of the widget. Click Done when done.

    You can select which part of the widget you want to Display. For instance, only the System panel (gauges), only the Network panel or both.

    The widget displays the Temperature of S.M.A.R.T. Disks and the Battery temperature on MacBooks. Select °C to display the temperature in Celsius or °F for Fahrenheit.

    You can change the Appearance of the widget by selecting between two different color themes. The Inherit theme is the one displayed here and match the default background used in the Notification Center.

Frequently asked questions

If you have other questions or issues, please contact us.

  • Can I see CPU temperature and fan-speed?

    An App Store App is unfortunately not allowed to read system sensors so we cannot show detailed temperatures and other sensor data such as fan-speed. To provide sensor data we might create a helper-app in the future which can be downloaded outside of the App Store.

  • Can I see all processes?

    An App Store App is not allowed to read all processes on the system. This means that the Top-3 App List will not necessarily contain the processes that are currently using the most resources. The List will however show the applications that are using the most resources.

  • Are values in the Top-3 App List correct?

    CPU and Memory usage are correct for the main application process. Unfortunately, due to new sandbox limitations introduced in MacOS Mojave we are not able to aggregate the memory and CPU used by an Application's sub-processes.

  • What does the Thermal Gauge display?

    The Gauge displays the thermal state of the system. There are 4 thermal levels; normal, fair (fans running), serious and critical. The Thermal Apple API does not seem to work properly on older Macs. On MacBooks from 2015 and later it appears to work fine.

  • Wrong text colors in Dark or in Light Mode

    When you select the Inherit color theme, the Monit Widget adjust text colors and other colors to match the system appearance. That is, if you have setup your system for Dark Mode, text in the Widget will be light and in Light Mode, text will be dark. If you open Notification Center and then switch appearance from Light to Dark mode or vice-a-versa and then open Notification Center again the Widget may show the old and now wrong text colors. The reason for this is; when you close Notification Center, widgets will continue to run for ~ 30 seconds before they stop and keep their old appearance. Just wait 30 seconds before you open Notification Center and the Monit Widget will start again and show the correct text colors.
