Device Score Metrics: Categories and Definitions
This page provides a reference for all the main categories and associated metrics that DEX Manager Plus evaluates to determine each device’s experience score. Understanding these metrics helps both IT teams and end users know what factors influence the Device Score and, ultimately, the quality of the digital workspace.
1. Device Performance
Metrics in this category measure how efficiently the device’s hardware and network resources are being used:
| Metric | Definition |
|---|---|
| CPU Usage: | Measures the average percentage of processor use. High values can indicate potential slowdowns or resource contention. |
| CPU Interrupt: | Tracks the frequency of temporary interruptions in CPU operations, which may impact system efficiency. |
| Memory Swap Rate: | Records how often (pages per second) the system swaps data between RAM and disk, indicating memory pressure. |
| Memory Swap Size: | Measures the total size of memory being swapped, useful for identifying if insufficient RAM is leading to performance issues. |
| GPU Usage: | Monitors the load on the graphics processor, an important factor for devices running graphics-intensive software. |
| Disk Queue Length: | Counts the average number of read/write operations waiting on the storage drive, highlighting disk bottlenecks. |
| System Drive Free Space: | Quantifies the remaining available storage on the primary drive, where low space can degrade performance. |
| Wi-Fi Signal Strength: | Reflects the quality of the wireless network connection, which affects connectivity and application responsiveness. |
| Wi-Fi Receive Rate: | Measures the rate at which data is received over Wi-Fi, indicating download performance. |
| Wi-Fi Transmit Rate: | Measures the rate at which data is sent over Wi-Fi, indicating upload performance. |
| Network Output Queue Length: | Indicates the number of network packets queued for transmission, helping to identify network congestion or delays. |
2. Application Reliability
Metrics in this group assess the stability of critical applications:
| Metric | Definition |
|---|---|
| Application Crashes: | Counts the number of times key applications have crashed on the device in a given period. Frequent crashes reduce user productivity. |
3. Device Stability
This category encompasses hardware health and system resilience:
| Metric | Definition |
|---|---|
| System Crash: | The number of times the device has experienced a total system failure (such as a blue screen or kernel panic). |
| Device Age: | The time elapsed since the device was first activated or manufactured. Older devices may encounter more failures or performance issues. |
| Hard Reset: | Tracks the number of times users have forcibly restarted the device due to unresponsiveness or critical errors. |
| Battery Health: | Current battery capacity relative to the original design capacity, used to assess battery lifespan and the need for replacement. |
| Warranty: | The amount of time remaining such that the device is still under a valid manufacturer warranty. |
4. Device Responsiveness
These metrics directly impact how quickly the device responds to end-user actions:
| Metric | Definition |
|---|---|
| User Input Delay: | Measures the time between user actions (like mouse click or keyboard press) and the device’s response. |
| Logon Duration: | The time it takes from entering credentials until the user is fully logged in and can start work. |
| Boot Duration: | The total time from powering on the device to it being ready for use. |
5. User Sentiment
These metrics directly capture user sentiment via engage from Workflow. Refer to this document for more details
