Event Reference

What This Event Means

Event ID 1008 represents a failure in the Windows Performance Counter subsystem, specifically when the Performance Library (Perflib) cannot successfully load or initialize a performance counter provider. This event occurs during the enumeration and loading process of performance counter DLLs that expose system metrics to monitoring applications.

Performance counter providers are dynamic link libraries (DLLs) that implement specific interfaces to expose performance data about various system components, applications, or services. When Windows starts or when monitoring tools request performance data, Perflib attempts to load these providers. If a provider fails to load due to missing dependencies, corrupted files, or initialization errors, Event ID 1008 gets logged.

The event typically includes details about the failing provider, such as the service name, library path, and specific error codes. Common scenarios include third-party applications that install custom performance counters but leave orphaned registry entries after uninstallation, corrupted system files affecting built-in providers, or permission issues preventing proper DLL loading.

This event primarily affects monitoring and diagnostic capabilities rather than core system functionality. However, persistent 1008 events may indicate broader system health issues that warrant investigation, particularly in enterprise environments where comprehensive performance monitoring is critical for maintaining service levels.

Resolution Methods

Troubleshooting Steps

01

Identify the Failing Performance Counter Provider

Start by examining the Event ID 1008 details to identify which specific performance counter provider is failing.

  1. Open Event Viewer by pressing Win + R, typing eventvwr.msc, and pressing Enter
  2. Navigate to Windows LogsApplication
  3. Filter for Event ID 1008 by right-clicking the Application log and selecting Filter Current Log
  4. Enter 1008 in the Event IDs field and click OK
  5. Double-click the most recent Event ID 1008 entry to view details
  6. Note the service name and library path mentioned in the event description
  7. Use PowerShell to get detailed event information:
Get-WinEvent -FilterHashtable @{LogName='Application'; Id=1008} -MaxEvents 5 | Format-List TimeCreated, Id, LevelDisplayName, Message

Record the failing provider name and any error codes for use in subsequent troubleshooting steps.

02

Rebuild Performance Counter Registry

Rebuild the performance counter registry to resolve corrupted counter configurations.

  1. Open Command Prompt as Administrator
  2. Stop the Performance Logs and Alerts service:
net stop pla
  1. Navigate to the system32 directory:
cd /d %windir%\system32
  1. Rebuild the performance counter registry using lodctr:
lodctr /R
  1. If the above command fails, use the more comprehensive rebuild:
cd /d %windir%\inf
lodctr /R
  1. Restart the Performance Logs and Alerts service:
net start pla
  1. Verify the fix by checking for new Event ID 1008 entries after a system restart
Warning: The lodctr /R command rebuilds all performance counters, which may temporarily affect monitoring applications until they refresh their counter lists.
03

Remove Orphaned Performance Counter Entries

Clean up orphaned performance counter registry entries left by uninstalled applications.

  1. Open Registry Editor by pressing Win + R, typing regedit, and pressing Enter
  2. Navigate to the performance counter services key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
  1. Look for services mentioned in the Event ID 1008 error message
  2. For each problematic service, check if the Performance subkey exists
  3. If the parent service no longer exists but Performance subkeys remain, delete the orphaned entries
  4. Use PowerShell to identify potential orphaned entries:
Get-ChildItem "HKLM:\SYSTEM\CurrentControlSet\Services" | Where-Object { $_.GetSubKeyNames() -contains "Performance" } | ForEach-Object { $serviceName = $_.PSChildName; $service = Get-Service -Name $serviceName -ErrorAction SilentlyContinue; if (-not $service) { Write-Output "Potential orphan: $serviceName" } }
  1. Before deleting any registry keys, export them as backup:
reg export "HKLM\SYSTEM\CurrentControlSet\Services\[ServiceName]" C:\temp\perfcounter_backup.reg
  1. Restart the system after making registry changes
Pro tip: Always create a system restore point before modifying performance counter registry entries.
04

Run System File Checker and DISM

Repair corrupted system files that may be affecting performance counter providers.

  1. Open Command Prompt as Administrator
  2. Run System File Checker to scan for corrupted files:
sfc /scannow
  1. If SFC finds issues, run DISM to repair the Windows image:
DISM /Online /Cleanup-Image /RestoreHealth
  1. After DISM completes, run SFC again to ensure all files are repaired:
sfc /scannow
  1. Check the SFC log for details about repaired files:
Get-Content $env:windir\Logs\CBS\CBS.log | Select-String "\[SR\]" | Select-Object -Last 20
  1. Restart the system and monitor for Event ID 1008 recurrence
  2. If issues persist, consider running Windows Memory Diagnostic:
mdsched.exe

This comprehensive approach addresses potential file corruption that could prevent performance counter DLLs from loading properly.

05

Advanced Performance Counter Troubleshooting

Perform advanced diagnostics and manual performance counter provider investigation.

  1. Enable detailed performance counter logging by modifying the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib
  1. Create a new DWORD value named EventLogLevel and set it to 2 for verbose logging
  2. Use Performance Monitor to identify specific counter issues:
perfmon.exe
  1. In Performance Monitor, try adding counters from the failing provider to isolate the problem
  2. Use PowerShell to enumerate all performance counter categories and identify missing ones:
Get-Counter -ListSet * | Sort-Object CounterSetName | Format-Table CounterSetName, Description -AutoSize
  1. Check for specific DLL loading issues using Process Monitor (ProcMon):
  2. Download ProcMon from Microsoft Sysinternals
  3. Set filters for Process Name contains "winlogon" or "services"
  4. Look for ACCESS DENIED or PATH NOT FOUND errors related to performance counter DLLs
  5. Manually test performance counter provider loading:
$counterPath = "\\localhost\Processor(_Total)\% Processor Time"
try { Get-Counter -Counter $counterPath -MaxSamples 1 } catch { Write-Error "Counter access failed: $_" }
  1. If all else fails, consider using the Windows Performance Toolkit (WPT) for deeper analysis
  2. Reset the EventLogLevel registry value to 0 after troubleshooting to reduce log verbosity
Pro tip: Use Windows Performance Analyzer (WPA) from the Windows SDK to analyze performance counter behavior in detail for complex scenarios.

Overview

Event ID 1008 from the Perflib source fires when Windows Performance Counter infrastructure encounters issues loading or initializing a specific performance counter provider. This event commonly appears in the Application log when performance monitoring components fail to register properly during system startup or when monitoring applications attempt to access unavailable counter data.

The Performance Library (Perflib) manages Windows performance counters that provide real-time system metrics to tools like Performance Monitor, Task Manager, and third-party monitoring solutions. When a counter provider fails to load, you'll see this warning event with details about which specific provider encountered the problem.

While Event ID 1008 doesn't typically cause system instability, it can prevent monitoring tools from collecting complete performance data. The event often correlates with missing or corrupted performance counter libraries, registry corruption, or third-party software installation issues. System administrators should investigate these events to ensure comprehensive monitoring coverage and identify potential underlying system issues.

Frequently Asked Questions

What does Event ID 1008 mean and should I be concerned?+
Event ID 1008 indicates that a performance counter provider failed to load or initialize properly. While this is a warning-level event that typically doesn't affect core system functionality, it can prevent monitoring tools from collecting complete performance data. You should investigate if you rely on system monitoring or if the events occur frequently, as they may indicate underlying system issues like corrupted files or registry problems.
Can Event ID 1008 cause system performance problems?+
Event ID 1008 itself doesn't directly cause performance problems, but it indicates issues with the performance monitoring infrastructure. The failing performance counter providers won't impact system speed or stability. However, if the underlying cause is corrupted system files or registry corruption, those issues could potentially affect overall system health. The main impact is on monitoring capabilities rather than actual performance.
How do I identify which performance counter provider is failing?+
Open Event Viewer and navigate to Windows Logs → Application, then filter for Event ID 1008. The event details will specify the failing service name and library path. You can also use PowerShell: Get-WinEvent -FilterHashtable @{LogName='Application'; Id=1008} -MaxEvents 5 | Format-List Message to see the detailed error information including the specific provider that failed to load.
Is it safe to use lodctr /R to rebuild performance counters?+
Yes, lodctr /R is a safe Microsoft-provided command that rebuilds the performance counter registry from system INF files. It's designed specifically for resolving performance counter issues. However, it will temporarily reset all performance counter configurations, which may require monitoring applications to refresh their counter lists. Always run this command as Administrator and consider stopping monitoring services first to avoid conflicts.
Why do I get Event ID 1008 after uninstalling software?+
Many applications install custom performance counters but don't properly clean up their registry entries during uninstallation. This leaves orphaned performance counter references that Windows tries to load but can't find the associated DLL files. These orphaned entries trigger Event ID 1008. You can resolve this by manually removing the orphaned registry entries from HKLM\SYSTEM\CurrentControlSet\Services or using lodctr /R to rebuild the entire performance counter registry.
