when i am in Host Status Detail, under host - localhost , the status information always show (no output!).
however for another intranet host, the status information will show ping ok. for both host - **status **is up.
In addition, i found that my system time is two day earlier. i fix the time back to correct time. therefore all the records shown in duration is not correct. is there a way where i can reset all the record and start a new data collection?
