FullEventLogView比eventvwr的优势就不赘言了

说下使用技巧

外部机器.evtx的分析用它非常方便,.evtx一般在C:WindowsSystem32winevtLogs目录,要分析哪台机器的,把日志拿过来,在FullEventLogView里如下图指定数据源,数据源里的文件后缀用*.evtx

指定条件分析很方便:

条件维度如下图比较多,时间、事件级别、事件ID、来源、描述等

可以指定条件正向过滤,也可以指定条件反向过滤

扩展:

端口耗尽、tcpip相关日志

4227,4231,4266

开关机相关的事件ID

12,13,6005,6006,6008,41,1074

ProviderName:Microsoft-Windows-User Profiles Service

1530,1531,1532

ProviderName:Windows Error Reporting

1001

激活相关的事件ID

8197,8198,12288,12289

这样过滤(一般来说用事件ID过滤效率高,过滤得快,如果用description里的字符串过滤,效率会差一些,过滤得慢)

或者

powershell命令过滤日志举例:

tcpip来源的日志4227,4231,4266(如过滤到,则需要放大tcp动态端口范围、缩短timewait回收时间)

Get-EventLog -LogName System -Source Tcpip -ErrorAction SilentlyContinue |Where-Object {$_.EventID -eq "4227" -or $_.EventID -eq "4231" -or $_.EventID -eq "4266"} |FT TimeGenerated,EventID,EntryType,Source,Message

Get-WinEvent -FilterHashtable @{logname='System';id=@(4227,4232,4266);StartTime=(Get-Date).AddDays(-10)} -ErrorAction SilentlyContinue |Sort-Object -Property TimeCreated

Get-WinEvent -FilterHashtable @{logname='System';source='Tcpip';id=@(4227,4232,4266);StartTime=(Get-Date).AddDays(-10)} -ErrorAction SilentlyContinue |Sort-Object -Property TimeCreated

Get-WinEvent -FilterHashtable @{logname='System';id=@(12,6005,6006,13,6008,41,1074);StartTime="2021-07-27 00:00:00";EndTime="2021-07-28 00:00:00"}

Get-WinEvent -FilterHashtable @{logname='Application';id=@(1530,1531,1532,1001);StartTime="2021-07-27 00:00:00";EndTime="2021-08-28 00:00:00"}

其他例子:

#查最近1天的开关机、重启记录

Get-WinEvent -FilterHashtable @{logname='System';id=@(12,13,6005,6006,6008,1074,41);StartTime=(Get-Date).AddDays(-1)} -ErrorAction SilentlyContinue |Sort-Object -Property TimeCreated

#查最近1天登录相关的记录和Application报错

Get-WinEvent -FilterHashtable @{logname='Application';id=@(1530,1531,1532,1001);StartTime=(Get-Date).AddDays(-1)} -ErrorAction SilentlyContinue |Sort-Object -Property TimeCreated

#查最近1天的暴力破解记录

Get-WinEvent -FilterHashtable @{logname='Security';id=@(4625);StartTime=(Get-Date).AddDays(-1)} -ErrorAction SilentlyContinue |Sort-Object -Property TimeCreated
