    • Learn how the device health is being calculated and marked with Good, Average, or Poor performance indicators.

    Calculating Device health check

    Each category of the selected device is marked as Good, Average, or Poor by calculating the weighted average of the sub-categories associated with the parent category.

    Each sub-category’s performance is marked as Good, Average, or Poor by calculating the weighted average of the performance indicators of device metrics associated with the sub-category.
    Table 1. Performance indicators
    Performance Indicators Weight Upper bound Lower bound
    Good 1 1.67 1
    Average 2 2.33 1.67
    Poor 5 5 2.33
    Formula used to calculate the sub-category performance indicators
    Sub-category performance indicator= (weight of evaluation metrics performance indicator)/total number of evaluation metrics for the subcategory)
    where,
    • Evaluation metric performance indicator: Performance indicator (Good, Average, Poor) of the evaluation metrics' value as defined in the metric definition table. For more information, see Customize metric definitions.
    • Weight: Weight of the performance indicator. After all the sub-categories are marked as Good, Average, and Poor. The performance of the category is calculated by weighted average of sub-categories performance indicator.
    Score range definition

    The following defines the performance range and its corresponding classification:

    • Good if performance indicator average value lies in range of (1, 1.67)
    • Average performance indicator average value lies in range of (1.67, 2.33)
    • Poor performance indicator average value lies in range of (2.33, 5)
    Formula used to calculate the parent category performance indicator:
    Category performance indicator= (sum of sub-category performance indicator weights)/total number of sub-categories)
    Example
    Consider the following example for the calculating the performance indicator for Device performance category which has the below sub-categories:
    Table 2. Sample Device health check calculation
    Sub-category Metric Metric value Sub-category performance metric calculation Sub-category Performance indicator
    Disk Space Disk Usage 90 Sub-category performance indicator = 5 (i.e Weight of Poor indicator) / 1 (total no. of evaluation metrics for the subcategory) Poor
    Battery Health Battery health Good Sub-category performance indicator = 1 (i.e Weight of Good indicator) / 1 (total no. of evaluation metrics for the subcategory) Good
    Computer Restart Device uptime 1 Sub-category performance indicator = 1 (i.e Weight of Good indicator) / 1 (total no. of evaluation metrics for the subcategory) Good

    Performance indicator for Device performance category.

    • Sub-category performance indicators = Poor, Average, Good
    • Sum of weight of Sub-category performance indicators: (5 + 1 + 1) = 7 Performance indicator = 7 / 3 (no. Of sub-categories) = 2.33
    • Device performance category is Poor (as 2.33 falls under the Poor range)
