I have created experimental dashboard for possible inclusion in later Percona Monitoring and Management version, and I though it might be great to get some feedback about it before including it in release
Dashboard is available from Grafana.com so it should be very easy to add it to your PMM Installation
Please let me know if there is anything to improve before we include it in release.
Couple of things to note
Note red dots in CPU overview graph. It shows total CPU usage for busiest core. Very often we see some cores completely saturated being a bottleneck while overall CPU usage looks low
The table shows utilization details for all the CPU cores to help to spot the problems, for example if one core has high IOwait it will likely to correspond to single thread IO intensive process being blocked by IO a lot.
