I have 3 web server with load balance.
And I use logresolvemerge to analyze my web server logs.
When I analyze logs the result is success.
But when I look then results in webpage,the Viewed traffic are all zero.
And all records are in Not viewed traffic.
But when I analyze one log alone.It's all normal.
What error with it.Can anybody help me.
