Hi Lvan,
According to your description, my understanding is that you have two request of Pivot Table:
1) Summarize the data by each month
2) Calculate the uptime percent
Am I right? If yes, please we might try the methods below:
1) Grouping data in a PivotTable can help we summarize the data by each month. Steps:
- In the PivotTable, right-click any numeric or date and time field, and click Group.
- In the Starting at and Ending at box, enter this (as needed):Grouping dialog box.
The entry in the Ending at box should be larger or later than the entry in the Starting at box. - You can click additional time periods to group by. For example, you can group by Months and Weeks. Group items by weeks first, making sure Days is the only time period selected. In the Number of days box, click 7, and then click Months.

2) We can use calculated fields to calculate the uptime percent, for example:
Total Uptime - Total Downtime)/Total Uptime (Show value as percent)
