Up-time report ERRORS

Hi

I enabled the daily/weekly/monthly.
Most days everything is 100% which is great.
On days we have problems, the report appears to not always show the correct calculations.
I believe this is because I stopped the monitor during the incident.

Example: Daily up-time report fo 10 Dec 2014

Syst3046

99.8%

0.2% - 3min

Syst3083:Ping

7.0%

93.0% - 22h 18min

The monitor "Syst3083:Ping" is under component Syst3046.
The report for Syst3046 appears ok.
The report for Syst3083:Ping does not appear ok.
The incident for Syst3083 started at 20:41.
I realized that this was not an outage but a scheduled maintenance and so I stopped the monitor.
I restarted the monitor after the work was complete, which was roughly an hour later.
The daily report appears the monitor was down for 22 hours.
This is obviously incorrect since the monitor was up from 00:00 to 20:40.

Please let me know.
Thanks.
