View the SLA Compliance of Device Boot Times (Boot)

The Boot dashboard displays boot times for devices across your organization in comparison with SLA targets.

Long boot times contribute to a loss of productivity. The Boot dashboard enables you to see at a glance if the accumulated boot metrics from your monitored devices meet your SLAs. Use this dashboard as a starting point for monitoring boot times. If an issue is present, drill-down using the Boot Analysis dashboard so that you can identify and fix issues that can cause long boot times.

View the boot SLA compliance and the average boot times

For example, your helpdesk may have received complaints about long boot times. Using the Boot dashboard, you can assess whether there is a pattern to those complaints, which you may be able to track to a device driver or service pack.

To... Do This...

To quickly assess whether there are boot times that require attention

Use the SLA Breakdown pie-chart.

This pie-chart displays the compliance of boot times to your committed SLA.

Hover over a section of the chart to see details and a link to drill down to Boot Analysis.

To compare boot times for different operating systems, or to check if a long boot time is common to devices using the same operating system

Use the Operating System section.

To filter the display, select an area on the SLA Breakdown pie-chart.

To view the locations of the systems that fail their SLA and determine if a feature common to one location is causing slow boot times

Use the Geographies section to view results sorted by city, country, or region, or displayed on a map.

To filter the display, select an area on the SLA Breakdown pie-chart.

To view the boot behavior of a particular type of device (like desktops or laptops), for example, to assess if the cause of a slow boot is based on drivers or faulty hardware in certain devices

Select the type of the device in the Device Type drop-down menu in the top bar and view the SLA Breakdown pie-chart, the Operating Systems section, and the Geographies section.


  1. Step 1 Open a browser and sign in to Aternity.
  2. Step 2 Access the dashboard by typing its name in the search box in the top bar.

    Alternatively you can drill-down to this dashboard from the following dashboards:

    • Device Health

    • Desktop Reliability

    • Device Inventory

    • My Enterprise

  3. Step 3 Set the type of boot time you want to display to Total Boot, Machine Boot, or User Logon in the drop-down menu in the top bar.
    Choose boot time to display by selecting it in the top bar of this dashboard

    There are several boot times defined in Aternity.

    Aternity boot time measurements
    Field Description

    Total Boot

    The total boot time on a Windows device starts from the time the Windows logo appears until the desktop appears and all components are loaded. Agent queries Windows Event Log (ID 100) for the BootTime parameter, calculated as the sum of main path boot and post boot times, located in the Diagnostics > Performance > Windows section of the log.

    For details of main path boot and post boot times (not present in this dashboard), see Troubleshoot Boot Issues (Troubleshoot Boot).

    Machine Boot

    Machine boot is part of a device's boot time, starting a fraction of a second after the Windows logo appears, and ending with the Windows sign in screen. Agent queries Windows Kernel-PnP (NOT the Event Log) for the BootStart > Start event to mark the start of this time, and ends when the Windows sign in screen appears (or the automatic sign in process starts).

    User Logon

    User logon measures a part of the boot time, starting when you press OK at the Windows sign in screen and ending when the Windows desktop Start button appears. The Agent queries Windows Shell-Core (NOT the Event Log) for the Explorer_StartMenu_Ready event to mark the end of this time.


    The end of the User Logon and the end of the MainPathBoot do not coincide exactly.

  4. Step 4 View how many boots fail to meet your SLA, in the SLA Breakdown pie-chart.

    Hover over any area and click drill down to view the Boot Analysis dashboard, to investigate detailed causes of long boot times.

    View the boot compliance with your SLA threshold

    The values of the SLA thresholds (the SLA targets) are displayed below the chart.

    Field Description

    The number of boots that comply with the SLA.


    The number of boots whose time exceeds the internal SLA threshold. This is a first warning that devices in your organization have an increase in their boot time.


    The number of boots whose time exceeds the external SLA threshold.

  5. Step 5 View average boot time performance of each operating system in the Operating Systems section, and boot performance by location in the Geographies section.

    The Operating Systems section presents the number of boots and the average boot time per operating system, with the longest average boot time at the top by default. The score shows the operating systems that performed worst and which require immediate attention.

    The Geographies section presents the longest average boot time at the top, per location. In the drop-down menu in the top right corner of this section, choose to view the data by Countries, (default), States, Cities, Regions or Geographies (Map). Narrow down the issue to a specific area, where you may be aware of a change causing slow boot times.

    View which operating systems perform worst and their location
    Field Description
    Boot Performance Score
    The boot score is a reflection of the boot performance. Its status can be:
    Number of Boots

    The number of boots measured for the selected operating system.

    Average Boot Time

    The average of all the boot times of devices running that operating system (displayed in hours, minutes, and seconds). The average can be of the total boot time, the machine boot time or the user logon time depending on your choice in the View drop-down menu.

  6. Step 6 Hover over the boot performance score icons or over the average boot time horizontal bars to view detailed boot time information.
    Field Description

    The average of the monitored boot times [hours:minutes:seconds].


    The number of boots monitored during the selected timeframe.


    The number of boots shorter than the SLA's minor threshold


    The number of boots that exceed the SLA's minor threshold. These boots are not ideal, and should be monitored for further degradation.


    The number of boots exceeding the SLA's major threshold. These require investigation and mitigation.


    This activity status is not applicable for boot times.


    This activity status is not applicable for boot times.


    The score of the average of the boot times for this operating system.


    Average boot status based on the score: Good, Fair, Poor, Unacceptable.

  7. Step 7 Check the possible correlation between the worst performing operating systems and their geographic distribution.

    After you identify a boot problem with the pie chart, you can determine if all slow boots have a common location or operating system. Select the relevant area (yellow or orange) in the SLA Breakdown pie-chart, and view the Operating Systems and Geographies sections.

    For example, if you select the orange area in the pie-chart, check how the operating systems perform against each other, and select the slowest one. See if the selected operating system is installed in one or several locations in the Geographies section. The longest boots are displayed first. Long boot times in a certain zone could be an indication of a network problem that needs attention.

    View only the boots which least complied with your SLA threshold

    To view more information, drill-down to the Boot Analysis dashboard. There you can view more detailed information, including the recent trend in boot times, the list of each individual process which has a longer than usual boot, or the users and departments that experience boot issues and their device model.

  8. Step 8 To limit the display to a certain type of device or to show the boot data for specific periods of time, use the drop-down menus in the top bar of the dashboard.
    Changing the scope and details of the Boot dashboard




    Choose the start time of the data displayed in this dashboard.

    You can access data in this dashboard (retention) going back up to 30 days. This dashboard's data refreshes every hour.

    Device Type

    Select to view the boot times for a single type of device.


    Only desktops, laptops, tablets and virtual desktops have a boot sequence, so only these device types are displayed in this dashboard.

    You can continue your investigation to see when the boot problems started, by choosing different periods of time in the Timeframe drop-down menu. To pinpoint the day when the boot performance decreased, see the Boot Analysis dashboard.
