All,
I am seeing very regular spikes in both page splits per second and logical reads per second at 5 minute intervals. These appear on all of my database servers, although the magnitude varies. I have started to wonder if these spikes are related to SoSSE data collection. I have used Extended Events to capture split events and most of them seem to be related to SoSSE and most are on tempdb pages. Traces have shown some SoSSE queries to have high read counts. My fear is that these spikes are an artifact of the monitoring, and they're high enough relative to normal background "noise" on the database to mask behaviors that might be of serious concern.
Has anyone else seen this kind of behavior? Does anyone have any suggestions as to how to nail down the cause? Thanks for any thoughts you might have.
