Thresholds
Last updated December 19th, 2024
On the THRESHOLDS tab, you can set the conditions for when certain dashboard insights trigger alerts. This tab is broken down into the following sections:
Today’s issues
Drag the sliders to adjust the yellow and red thresholds, which represent the percentage of impacted devices required before an alert is sent.
Take, for example, a case where you’re managing a group of 100 devices. The yellow alert threshold for Abnormal app events is set to 15% and the red threshold is set to 25%. You would receive an email alert when 16 devices report an abnormal app event, and another when 26 devices report an event.
TODAY’S ISSUES also supports device groups. Admins can set a minimum number of devices for a group to trigger an email alert. Doing so ensures you only receive relevant alerts for the devices you’re managing. Under the sliders, enter a minimum number of devices for a group. Any device groups below the specified minimum size are ignored in threshold event calculations.
Once you’ve configured your thresholds in Today’s issues, you can configure Knox Asset Intelligence to send email alerts once thresholds are crossed. See Manage email preferences for details on how to configure these alerts.
Network
The following Network threshold options are available:
Wi-Fi Disconnections
You may want to track whether a certain number of Wi-Fi disconnection events are occurring, based on the following conditions:
- BSSIDs (basic service set identifiers) with a certain number of disconnection events, per day
- Devices with a certain number of disconnection events, per day
- Groups that contain devices with a certain number of disconnection events, per day
Enter a number of events as a threshold for each category. This number must exceed 1. Once the detected number of disconnection events exceeds the threshold, an email alert is triggered.
In the top-right corner of the NETWORK section, enable Recommended Wi-Fi disconnection thresholds to have the service intelligently define Wi-Fi disconnection event thresholds based on an internal statistical model. This option is only available once Knox Asset Intelligence has collected enough network data from your devices. If you enable the recommended values and save your changes, the existing threshold values are overridden for all admins in your tenant.
Data usage by connection type (mobile)
To set this alert threshold, set a data usage value in GB, and a day of the month for which the alert is triggered.
For example, you can set an alert to show when your entire fleet uses more than 100 GB of mobile data since the 4th of each month.
- If your current day is the 5th of the month, you’ll see an alert if your fleet consumed more than 100 GB of mobile data since the 4th of this month.
- If your current day is the 3rd of the month, you’ll see an alert if your fleet consumed more than 100 GB of mobile data since the 4th of last month.
- If your curent date is the 4th of the month, you will not see an alert since the data has not passed yet.
App
To identify apps that are consuming abnormally large amounts of battery or network data, you can set threshold percentages for both battery consumption and network usage. These thresholds are measured per day and per device. If an app exceeds one of the thresholds, the device records it as an event and the data is displayed as an insight in the relevant dashboard charts.
If a small number of your devices are reporting high app usage statistics that aren’t representative of the whole device fleet, you can also enter a minimum device count to ignore app data from those devices.
In the top-right corner of the APP section, enable Recommended app thresholds to have the service intelligently define app battery and network consumption event thresholds based on an internal statistical model.
If you’ve added Managed Applications in Settings > MANAGED APPS, you’ll see a checkbox indicating that only managed apps are used by default when calculating recommended app battery and network consumption. To calculate recommended thresholds based on all apps in your organization, clear the checkbox.
Battery
In the THRESHOLDS > BATTERY section, you can define the conditions that determine when data gets reported, and when alerts get triggered.
You can configure two categories of battery thresholds:
- General data thresholds that affect all battery insights
- Alert thresholds that affect the battery tiles on the Dashboard
General data thresholds
| Option | Description |
|---|---|
| Low battery level | Specify the battery level percentage that would produce any low battery related data. For example, setting 25% means a device would only report low battery related data if its battery level drops to 25% or lower. |
| Battery drain event | Specify the total battery percentage that — if the device consumes in one hour or less — would produce a battery drain event. For example, setting 10% means a device would report a battery drain event if its battery drops 10% in an under an hour. |
Alert thresholds
| Option | Description |
|---|---|
| State of health | Specify the percentage of devices in your fleet that must report a Bad battery state of health before an alert is triggered on the Battery state of health dashboard tile. For example, 10 means that at least 10% of all devices must report a Bad battery state of health before the alert is sent. |
| Low battery events | Specify the percentage of devices in your fleet that must report an average of at least 1, 2, or more than 2 low battery events in a day before an alert is triggered on either the Low battery events, Groups with low battery events, or Groups with low battery devices at shift start dashboard tiles. |
| Battery drain events | Specify the percentage of devices in your fleet that must report at least 1, 2, or more than 2 battery drain events in a day before an alert is triggered on the Battery drain events dashboard tile. |
| Charge events | Specify the percentage of devices in your fleet that must report at least 1, 2, or more than 2 battery charge events in a day before an alert is triggered on the Charge events dashboard tile. |
Recommended thresholds
In the top-right corner of the BATTERY section, enable Recommended low battery & battery drain thresholds to have the system intelligently define battery event thresholds based on an internal statistical model.
This option is only available once Knox Asset Intelligence has collected enough battery data from your devices. If you enable the recommended thresholds option, the existing threshold values are overridden for all admins in your tenant.
