Unified Logging System (ULS) 

Eye for sharepoint and each event Report generating

We can see three ways:

• SharePoint trace logs
• Windows Event Log
• SharePoint logging database
  
   Trace logs
  
  C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15
  
  The naming format for the trace log files is machinename-YYYYMMDD-HHMM.log, in 24-hour time.
   By default, a new log file is created every 30 minutes.
   You can change the interval by using Windows PowerShell with the Set-SPDiagosticConfig command. 
  The following powershell code snippet configures SharePoint to create a new trace log every 60 minutes.
  Set-SPDiagnosticConfig Set-SPDiagnosticConfig -LogCutInterval 60
  Get-SPDiagnosticConfig outputGet-Help set-SPDiagnosticConfig -ExamplesSet-SPDiagnosticConfig -LogLocation e:\Logs
  
  

  SharePoint LogLevel:
  Get-Command -Noun SPLogLevel
  

  Using SPLogEvent and SPLogFile:
  
  

  Get-SPLogEvent | Select -First 5

  Get-SPLogEvent | Select -Last 5

  Get-SPLogEvent | Select -First 20 -Last 10

  
  

  In Central Administration, click Monitoring on the left, and then select Configure Diagnostic Logging under the Reporting section
