The percent availability value is calculated by first summing the duration of all events of a particular class with a production state of Production and with a severity greater than or equal to a specified severity in the filter criteria. This sum is then divided by the total duration of the time range, and then subtracted from 1 and multiplied by 100 to get the percent available, as in the following equation:
1 - ((Total event down time) / (total duration)) * 100
Note: Events whose firsttime and lasttime fields are the same are not used in the calculation. These could represent an event that occurs and is subsequently cleared by the next event, or an event that has happened only once in the specific date range.
