Key Task: Analyze Host Resources (HRC)

Use the Analyze Host Resources dashboard to find the devices with the highest CPU and memory usage (HRC, not the usage by one application). You can verify a hypothesis about high resource usage to find the common elements in all poorly-performing devices, by correlating high HRC with other system or software attributes.


There are several dashboards within this one; select Measurement Group to access the data you need.

For example, if some devices suffer poor performance, use this dashboard to verify whether a driver update causes the problem in the Sales department in Seattle where they upgraded their OS. Use Measurement Group > Overview to quickly check disk, CPU, and memory usage, then drill down for further details on one of those groups in the Measurement Group section. Set filters for department, location, and OS version, and check for correlations in resource usage. Adjust the filters further as necessary to narrow your investigation.

Analyze Host Resources dashboard

You can also view and analyze this data using the HOST_RESOURCES_HOURLY REST API. (Learn more).

  1. Step 1 Open a browser and sign in to Aternity.
  2. Step 2 SelectMain Menu > Analyze > Host Resources.
    Open the Analyze Host Resources dashboard
  3. Step 3 Choose the data to view for your investigation, by selecting Measurement Group on the right hand side.
    Analyze Host Resources dashboard

    Aternity only offers to narrow data with filter values which are available. It does not offer values which have not been reported. For example, if you select Week Number as your filter, it will only display the weeks for which monitoring data is available.

    Field Description

    This view displays a mix of CPU, memory, and disk use information, for a general picture of resource usage before zeroing in on one of those attributes.This view does not present network read and write data.

    Memory and CPU

    This view focuses on details of CPU and memory information.


    This view focuses on network read and write speeds, measured in bytes per second.


    This view focuses on disk input and output details.

  4. Step 4 Focus your dashboard using Breakdowns and Filters, to assess whether you are on the right track to understand the cause of the issue.
    1. a Select the two criteria (Breakdowns) that you want to correlate, using the panel on the right hand side.

      When you choose two Breakdowns, Aternity displays them as the two leftmost columns of the dashboard.

    2. b Choose Filters and Filter Values to limit the display to the data where the attribute has that value.
    Choose the two criteria (Breakdowns) to check for correlations and narrow further with filters

    For example, if you want to view the offices and device types which experience high resource usage, select Business Locations and Device Types as breakdowns. If you see that memory and CPU are showing high usage, select Measurement > Memory and CPU to focus on those attributes. Your breakdowns automatically remain in place. Add filters to further investigate the resource issues you see, such as setting Device Type > Desktop.

    Select any of the following fields to appear as Breakdowns or Filters.

    Field Description
    Business Locations

    Displays the name of the current location of the device. This is different from the Office, which is fixed for each user.

    For example, if a user based in the Houston office is working from the Chicago office, the Office is Houston, while the Business Location is Chicago.


    Only displays if you defined a custom attribute using this predefined name.

    Use this name for an attribute which differentiates a device, user or location along internal business units or areas of the company like retail outlet or customer service center.


    Displays the city of the current location of the device.


    Displays the country of the current location of the device.

    # CPU Cores

    (Desktops, laptops and mobile devices only) Displays the number of CPU cores of the device, the number of logical processors and not the physical cores.

    CPU Frequency

    (Windows, Macs only) Displays the speed of the CPU processors of the device.

    CPU Generation

    (Windows on Intel only) Displays the generation of the Intel Core micro-architecture. For example 6 represents the 6th generation architecture processor, also known as Skylake.

    CPU Model

    (Windows on Intel only) Displays the model and speed of the Intel processor, as displayed in the System control panel. For example Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz or Intel(R) Xeon(R) CPU E5620 @ 2.40GHz.

    CPU Type

    (Windows on Intel only) Displays the core type of the Intel processor, for example i7, E5, and so on).

    Days from Last Boot

    Displays the number of days since the last time the device was booted. If you think that people experience slowdowns because they have not booted in some time, you can compare their performance with users who restart their devices frequently.

    Do not compare the total number of boots/devices shown in different dashboards as the dashboards show different data from different data sources. The Boot or Boot Analysis show the total number of devices that rebooted from the time a user was viewing the dashboard and backwards during the selected timeframe; whereas the Analyze Host Resources shows the total number of devices that rebooted from the time the last HRC measurement was taken. This value appears under Number of Devices in one dashboard and as Machine Boot Activities in another.

    Day of Week

    Select to filter the displayed data for one or more days in the week.


    Check if the drop in performance is centered around a specific department, which can point to a configuration which is unique to that group of users, by viewing the performance in the list of departments. For example, if you find that only the Sales department is suffering poor performance, you can trace it to an upgrade which only happened on their computers, like a new CTI which interferes with your application.

    Device Name

    Displays the hostname of the monitored device. View it in the Windows Control Panel > System > Computer Name, or on Apple Macs in System Preferences > Sharing > Computer Name.

    (Mobile) Displays the Device Name field. You can customize the hostname of iOS or Android devices running your enterprise's app, so device names appear in the dashboards with a consistent naming policy. For example, you can dynamically assign the device name according to the enterprise username of the app.

    Device Types

    Check if the problem only affects users working on specific types of devices, like only those accessing the application on a tablet.


    (Windows only) Displays the email address associated with the current logged in user.
