While troubleshooting increased wait times - like higher than usual HADR_SYNC_COMMIT wait - in a SQL Server availability group, there are several tools that I can employ, across multiple servers. This particular wait could be caused by network latency, disk IO, high CPU, etc. It would be great if there were at least some baseline info in the "AG" section on DPA, like charting the time to harden a log block. Ideally, I'd like to see network throughput and disk write speeds on the synchronous secondaries, so I could narrow down the problem area.
