Machine Crashes & Hangs Metrics

Windows Blue Screens and Hangs

uberAgent collects information on every blue screen and hang, like the type of error (blue screen, hard power off or hang) and the stop error code.

Details

  • Source type: uberAgent:System:Bugcheck
  • Used in dashboards: Stop Errors (Blue Screen & Power Loss)
  • Enabled through configuration setting: ApplicationErrors
  • Related configuration settings: n/a
  • Supported platform: Windows

List of Fields in the Raw Agent Data

Field Description Data type Unit Example
BugcheckCode Stop error code ID. Possible values: too many to list here. Please check the lookup file bugcheck_codes.csv or Microsoft’s bug check code reference. Number 0x1
BugcheckParameter1 Stop error parameter 1. The meaning of this value depends on the bugcheck code and can be looked up in Microsoft’s bug check code reference. String 0x7ffd8e8c7864
BugcheckParameter2 Stop error parameter 2. The meaning of this value depends on the bugcheck code and can be looked up in Microsoft’s bug check code reference. String 0x1
BugcheckParameter3 Stop error parameter 3. The meaning of this value depends on the bugcheck code and can be looked up in Microsoft’s bug check code reference. String 0x0
BugcheckParameter4 Stop error parameter 4. The meaning of this value depends on the bugcheck code and can be looked up in Microsoft’s bug check code reference. String 0xffffe181ead22b80
SleepInProgress Indicates if the machine was in sleep mode when stop error occurred. Possible values: 0, 1. Number 0
PowerButtonTimestamp Indicates if the power button on the computer was pushed and held for at least four seconds. Possible values: 0 or Windows FILETIME timestamp of when the power button was pressed. Number 131768171003182508
PowerButtonTimestampEpoch Indicates if the power button on the computer was pushed and held for at least four seconds. Possible values: 0 or Unix epoch timestamp of when the power button was pressed. Number 1532343500318
BootAppStatus n/a String 0
Checkpoint n/a Number 0
ConnectedStandbyInProgress Indicates if the machine was in connected standby mode when a stop error occurred. Possible values: 0, 1. String 0
SystemSleepTransitionsToOn Indicates if the machine was in the transition from sleep to on mode when a stop error occurred. Possible values: 0, 1. Number 0
CsEntryScenarioInstanceId n/a Number 0

List of Calculated Fields

Field Description Data type Unit Example Where available
BugcheckCodeDisplayName Stop error code name. Possible values: too many to list here. Please check the lookup file bugcheck_codes.csv or Microsoft’s bug check code reference. String Hard power off Splunk data model

Interpreting the Data

The data collected by uberAgent helps to identify three different types of blue screens and hangs:

“Normal” Bugcheck

Conditions:

  • BugcheckCode > 0

Explanation: the bugcheck code can be determined and written to disk before the computer shuts down or restarts.

Hard Power Off

Conditions:

  • PowerButtonTimestamp > 0

Explanation: the machine was turned off by pressing and holding the power button for at least 4 seconds.

Random Restart

Conditions:

  • BugcheckCode = 0
  • PowerButtonTimestamp = 0

Explanation: power loss or hard hang.

macOS Kernel Panics

uberAgent collects information on every macOS kernel panic and reports details like bug type, kernel version and more.

Details

  • Source type: uberAgent:System:MacOsErrors
  • Enabled through configuration setting: ApplicationErrors
  • Related configuration settings: n/a
  • Supported platform: macOS

List of Fields in the Raw Agent Data

Field Description Data type Example
KernelBuild The macOS build version that the system was running when the panic occurred. String macOS 14.1 (23B74)
KernelProduct The model identifier for the machine. String Mac13,1
KernelVersion The version of the Darwin kernel that was running. String Darwin Kernel Version 23.1.0: Mon Oct 9 21:27:24 PDT 2023; root:xnu-10002.41.9~6/RELEASE_ARM64_T6000
KernelIncident A unique identifier for the specific panic incident. String 0039B7C3-9D24-4DF4-B08F-432475FCA067
KernelCrashReporterKey A unique identifier that helps Apple track the crash report without revealing personal information. String 7E439903-F3C7-16EB-ED55-F393AE09615C
KernelPanicString The actual panic message which contains the reason for the panic. CPU state and the call stack leading up to the panic are excluded. String panic(cpu 2 caller 0xfffffe001a373598): dtrace: panic action at probe dtrace:::BEGIN (ecb 0xfffffe1b2f31a140) @dtrace.c:6673
KernelPanicFlags Flags that provide additional information about the panic, useful for debugging. String 0x802
KernelBugType An internal Apple classification code for the type of crash or panic. Available from macOS 14 (Sonoma) upwards. Number 210
KernelErrorType The type of system error that occurred. Value 1 indicates system error type Crash Number 1
