This is a SAM template that checks the remaining capacity of a device running Windows 7 or newer. It requires Powershell 2.0 or newer to work.
The need to monitor a mobile device running the Windows OS, with a battery, are numerous. But a primary example is that you might have battery powered point-of-sale devices that you need to know if it is running low on battery or not. This is a monitor that can help with that data. A benefit of this monitor is that when you use the monitor's historical data and run reports for events or alerts, this could help you determine if a battery needs to be replaced in the device due to age or capacity.
The Powershell script in the monitor itself is very simple (see reference link below for source):
$stat = (Get-WmiObject win32_battery).estimatedChargeRemaining
Write-Host 'Statistic: ' $stat
The thresholds are configurable but here are the defaults:
Warning = Less Than or Equal to 30 for a Single Poll
Critical = Less Than or Equal to 15 for a Single Poll
