多个服务器的 Powershell Get_EventLog [英] Powershell Get_EventLog for multiple servers

问题描述

我是一名 SQL DBA，n00b 到 Powershell，目前负责系统管理员职责

I'm a SQL DBA, n00b to Powershell, tasked with sysadmin duties at the moment

我需要在我的服务器上查询错误日志以获取错误和警告.

I need to query error logs across my servers for Errors and Warnings.

使用我自己的 Google-fu 和来自 的帮助这个线程我能够让它工作:

Using my own Google-fu and help from this thread I was able to get this working:

 $computers = Get-Content "C:\Servers\ServerList_Short.txt"; 

# QUERY COMPUTER SYSTEM EVENT LOG
foreach($computer in $computers)

{        
     Get-EventLog -ComputerName $computer -LogName System -EntryType "Error","Warning" -After (Get-Date).Adddays(-7) `
     | Select-Object -Property machineName, EntryType, EventID, TimeGenerated, Message `
     | Format-Table -Property MachineName, TimeGenerated, EntryType, Source,  Message -AutoSize ;

}

我目前缺少的是如何在我的 .txt 文件中为离线的服务器设置陷阱，忽略它并移至下一个.之后，我将努力将所有这些转储到 SQL 表、results.txt 等中.

What I am missing at the moment is how to trap for a server in my .txt file that is offline, ignore it and move to the next one. After that, I will be working to dump all of this to a SQL table, results.txt, etc.

推荐答案

有几种不同的方法可以解决这个问题，但我建议将 Test-Connection 与 Try/Catch，Test-Connection 将使您只尝试查询响应 ping 的服务器，然后 Try/Catch 将处理任何其他可能出现的错误.

There are a few different ways to handle this but I'd recommend combining a Test-Connection with a Try/Catch, the Test-Connection will make it so that you only try to query the servers which respond to ping and then the Try/Catch will handle any other errors that may come along.

foreach($computer in $computers)

{        
 if(Test-Connection $computer -Quiet -Count 1){
    Try {
        Get-EventLog -ComputerName $computer -LogName System -EntryType "Error","Warning" -After (Get-Date).Adddays(-7) `
     | Select-Object -Property machineName, EntryType, EventID, TimeGenerated, Message `
     | Format-Table -Property MachineName, TimeGenerated, EntryType, Source,  Message -AutoSize
    } Catch {
        Write-Verbose "Error $($error[0]) encountered when attempting to get events from  $computer"
    }
 } else {
    Write-Verbose "Failed to connect to $computer"
 }

}
