Hello Community
How can explain please what is the diffrence between 50% latency and 90% latency?
40%....lol Latency in regards to what?
Between MX and his remote peer
The Latency graph shows the latency in a 50th Percentile, 90th Percentile, or a Histogram View. In the Histogram view, hovering over a box will give you details for that time period. The 50% option shows the median round-trip time for pings used to monitor the site-to-site VPN connection. The 90% option will show you the results of the top 10% of pings.
Typically, use the 50% option to view the average, the 90% option to view spikes in latency over the time period, and the histogram view to get detailed data for a specific time within the time period. When there are network problems (like poor voice quality) that can be related to latency, the 90% or histogram views will help troubleshoot whether those events correlate to VPN latency issues.

I dis read what you wrote in the Meraki documentation, but I did not got it 😁
If you can explain it to me differently, it gonna be great
Thank you 🙂
Top 10% may be confusing here. It's the 10% highest, i.e. worst latencies. You can also look at it like this: how high do I need to set the latency bar to catch 90% of the results. 90% of the actual latencies will be at or better than the value shown in that 90% graph. 50% of the actual latencies will be at or better than the value shown in that 50% graph.
It therefore also makes sense that the value shown for 90th will be a worse latency i.e. a higher value than the 50th percentile.
Agreed @Network-dad ?
Thank you!
