Heya all – here are a couple of quick functions to help analyze logs files. Coming from a ConfigMgr\/SCCM background, I got used to reading a LOT of logs. Having a couple of functions like this would have greatly helped!<\/p>\n\n\n\n
First – let’s see if there are warning and\/or error messages in a log (or stack of logs)<\/p>\n\n\n\n
function Analyze-LogContent {\n [CmdletBinding()]\n param (\n [Parameter(Mandatory=$true)]\n [string]$LogFilePath,\n\n [string]$ErrorPattern = 'ERROR|Error|error',\n [string]$WarningPattern = 'WARNING|Warning|warning'\n )\n\n if (-not (Test-Path -Path $LogFilePath)) {\n Write-Error "Log file does not exist at the path: $LogFilePath"\n return\n }\n\n # Reading the log file\n $logContent = Get-Content -Path $LogFilePath\n\n # Analyzing for errors\n $errors = $logContent | Where-Object { $_ -match $ErrorPattern }\n $warnings = $logContent | Where-Object { $_ -match $WarningPattern }\n\n # Output analysis\n $output = @()\n if ($errors.Count -gt 0) {\n $output += "Found $($errors.Count) errors in the log."\n } else {\n $output += "No errors found in the log."\n }\n\n if ($warnings.Count -gt 0) {\n $output += "Found $($warnings.Count) warnings in the log."\n } else {\n $output += "No warnings found in the log."\n }\n\n return $output\n}\n\n# Example usage\n$logPath = "C:\\Path\\To\\Your\\LogFile.log"\n$result = Analyze-LogContent -LogFilePath $logPath\n$result | ForEach-Object { Write-Host $_ }\n<\/pre><\/div>\n\n\n\nChange the patterns as necessary – ERR, for example.<\/p>\n\n\n\n
<\/p>\n\n\n\n
The second function is pretty straight forward – summarize a log counting the number of INFO, Warning, and Error messages: <\/p>\n\n\n\n
function Summarize-LogFile {\n [CmdletBinding()]\n param (\n [Parameter(Mandatory=$true)]\n [string]$LogFilePath\n )\n\n if (-not (Test-Path -Path $LogFilePath)) {\n Write-Error "Log file does not exist at the path: $LogFilePath"\n return\n }\n\n $logContent = Get-Content -Path $LogFilePath\n\n $infoCount = 0\n $errorCount = 0\n $warningCount = 0\n\n foreach ($line in $logContent) {\n switch -Regex ($line) {\n "INFO" { $infoCount++ }\n "ERROR" { $errorCount++ }\n "WARNING" { $warningCount++ }\n }\n }\n\n $summary = @"\nLog File Summary:\nInfo Entries: $infoCount\nError Entries: $errorCount\nWarning Entries: $warningCount\nTotal Entries: $($logContent.Count)\n"@\n\n return $summary\n}\n\n# Example usage\n$logPath = "C:\\Path\\To\\Your\\LogFile.log"\n$summary = Summarize-LogFile -LogFilePath $logPath\nWrite-Host $summary\n<\/pre><\/div>\n\n\n\nThere ya go! I will keep adding to these, and eventually get them in Github so you all can tell me how wrong they are \ud83d\ude42<\/p>\n\n\n\n
Happy Coding!<\/p>\n","protected":false},"excerpt":{"rendered":"
