GetNumberOfEventLogRecords返回不正确的事件日志数 [英] GetNumberOfEventLogRecords returns incorrect number of event logs
问题描述
我有这个C ++代码读取事件日志记录
I have this C++ code to read the event log records
DWORD GetLogRecords(LPCWSTR wsLogFile)
{
HANDLE hEvt = OpenEventLog(NULL, wsLogFile);
if (hEvt==NULL) return 0;
DWORD dwTotalRecords;
BOOL res = GetNumberOfEventLogRecords(hEvt, &dwTotalRecords);
CloseEventLog(hEvt);
return (res != 0) ? dwTotalRecords : 0;
}
结果
atlTraceGeneral - C:\Windows\system32\winevt\logs\ACEEventLog.evtx - 23499 Total Records
atlTraceGeneral - C:\Windows\system32\winevt\logs\Application.evtx - 23499 Total Records
atlTraceGeneral - C:\Windows\system32\winevt\logs\ConnectionInfo.evtx - 23499 Total Records
atlTraceGeneral - C:\Windows\system32\winevt\logs\Error.evtx - 23499 Total Records
atlTraceGeneral - C:\Windows\system32\winevt\logs\HardwareEvents.evtx - 23499 Total Records
atlTraceGeneral - C:\Windows\system32\winevt\logs\Internet Explorer.evtx - 23499 Total Records
atlTraceGeneral - C:\Windows\system32\winevt\logs\Key Management Service.evtx - 23499 Total Records
...
此功能与我的计算机上的所有.EVTX日志文件的完整路径(150个日志文件)。并且每次返回23499!我的日志文件有不同的大小和一些0,为什么我总是得到23499?
I have called this function with the full path of all the .EVTX log files on my computer (150 log files). And each time it returns 23499 ! My log files have different sizes and some 0, why I always get 23499 ?
UPDATE2:在我清除应用程序日志现在我获得0的所有.evtx日志文件。我认为它总是获取应用程序日志而不是指定的.evtx文件。
UPDATE2: After I have cleared the Application logs now I get 0 for all the .evtx log files. I think it always gets the application log instead of the specified .evtx file.
更新:正如Remy Lebeau建议的,但仍然是相同的结果。
UPDATE: As Remy Lebeau suggested, but still the same result.
推荐答案
为了其他人的利益,这个问题的解决方案是 OpenEventLog
路径名。而是必须给它事件日志的源名称(类似HardwareEvents
)。
For the benefit of others, the solution to this problem is that OpenEventLog
doesn't accept a pathname. Instead you have to give it the source name of the event log (something like "HardwareEvents"
).
如果调用具有无效源名称(包括提供路径名)的 OpenEventLog
,那么如文档所述,它将打开
log:
If you call OpenEventLog
with an invalid source name (which includes providing a pathname), then as documented it will open the Application
log instead:
如果指定自定义日志并且找不到, b服务打开应用程序日志。
If you specify a custom log and it cannot be found, the event logging service opens the Application log.
