It is possible to make this report concentrated by Month.
At the end I used a historical report, this could give me the summarized fields.
Thank you.
For a 'historical' report sure. But not for a 'current status' report. Even if you could, they would all say July.
If you exposed the SQL behind the report and the report was historical, you could do the 'group by' option on any field (such as month).
See details here (relevant info even though your question is not about custom SLA): https://support.solarwinds.com/Success_Center/Network_Performance_Monitor_(NPM)/Understanding_the_Custom_SLA_Report_SWQL_query
Note the description about 'The GROUP BY clause' in the above URL. As I stated earlier, doing something like this on a 'current status' flavor of report would yield a report with July showing everywhere if you ran it today. Which wouldn't really achieve anything. Group by something else and you may appreciate why grouping by month for a 'current' report doesn't really achieve anything useful.
Thank you for the link.
It's true, thanks for the observation.
So you have restated an answer you were given and then marked yourself correct?
