Network Uptime Report

On my old monitoring software, I had a network uptime report ("uptime" being based on ping return % over the past month). This would take the uptime of all my switches into an aggregate % and tell me that I had a network uptime of 99.98% (or whatever my % was) for last month. I am trying to recreate this report in PRTG but I can't quite figure out how to aggregate the individual switch uptime into 1 number. The only way I've found so far is to have all the switches that I want in 1 report, manually add the uptime together, then divide by the number of switches. Obviously this isn't a very eloquent solution. Is there some way to aggregate these in a report... or perhaps it's already done in the report and I'm not reading the report correctly?

Hello,

Thank you for contacting us,

In Reports > Select Report There is a template in the reports called Top 100 Uptime/Downtime. The you can go to the tab to select the sensors manually or add the sensors by tag in the Report settings.

Reports show statistics for uptime (Up and Down in percent) and requests (Good and Failed in percent). Values between 5% and 95%, as well as 100% and 0%, are rounded to whole numbers without decimal places. Other values are shown with 3 decimal places. Because of rounding, the statistics in section Sensor Status History of the report might differ from the values in section Uptime Stats by few seconds. For more information please refer to this report manual

Is there a way to save this as a custom report? We have like 20 sites and I am only looking for information on 3 of them (that's what I'm responsible for) and the report may want to be used by others. My initial reaction to just looking at the top 100 doesn't feel super useful to me but I'll play with it and see if I can get it to generate some data that feels more useful.

Ok, using the "Top 10 uptime/downtime" template and including the Percentile, I seem to be getting some information (from the Percentile field) that could be useful for trend information and general network health status. Right now when I run the report it groups by sensor. Is there a way to group it by Probe Group Device instead of sensor? IE I want all 1 location stuff in it's own group where right now all the pings are together.

Reports always go to the lowest level. So it will always group by sensors. It cannot be set to group by probe. Perhaps running separate reports with the devices on each probe.

Ok, I think I'm getting somewhere and then I end up 1 step behind. I've decided that what I want to track is the average ping (in ms), the total CPU usage %, and the available free memory. When set my report to get just the "Total CPU" with "calculate percentage" on and at 99, I get back a 14% return for last month. Ok, fine. However, when I go into the CPU and look at the same time period I'm actually seeing only about a 7% CPU usage. So where is this 14% calculation coming from?
