磁盘空间与冗余连接监测-优快云博客

本文介绍两种监测机制：一是定期检查磁盘剩余空间，当空间低于阈值时，每隔五分钟发出警告；二是监测与冗余服务器的连接状态，若连接失败，将记录错误并重试。

方法一：

//判断磁盘剩余空间，若不够则抛弃当前数据，隔5分钟报一次错误
COleDateTime oleLast(m_stLastDiskNotEnouphPromptTime);
SYSTEMTIME stNow;
GetSystemTime(&stNow);
COleDateTime oleNow(stNow);
COleDateTimeSpan span = oleNow - oleLast;
double dSpan = span.GetTotalSeconds();
if (__int64(dSpan) > (5 * 60))
{
	DEBUG_TRACE_ERROR(WSTR("Disk space is less than min size. Alarm Record is missing! %s - %d"), __WFILENAME__, __LINE__);
	KXLOG_ERROR( WSTR( "Disk space is less than min size. Alarm data is missing! " ), KXSZ_LOG_CATEGORY_HISTORY );
	m_stLastDiskNotEnouphPromptTime = stNow;
}

方法二：

#define FAIL_OUT_INTERVAL			(300000)
static DWORD LastFailed		= 0;
DWORD		 CurrentTick	= GetTickCount();
bool		 FailOut		= ( CurrentTick < LastFailed ) || (  CurrentTick - LastFailed > FAIL_OUT_INTERVAL );

	
if( FailOut )
	{
		DEBUG_TRACE_ERROR( WSTR("Failed to connect to redundant server(%s:%s:%d)."),
							m_redundantHostAddr.c_str(),
							m_redundantHostPort.c_str() ,
							GetLastError());
		LastFailed = CurrentTick;
	}
