Descrizione

From @anurse on Wednesday, November 1, 2017 3:22:31 PM

Some events listed below. The goal is to add events that will help users solve problems so if these aren't going to do that job, feel free to suggest/discuss others!

  • Microsoft-AspNetCore-Session EventSource
    • SessionsCreated - Counts sessions created
    • SessionsLoaded - Counts the number of times a session is loaded from the provider (this happens on each request for a session)
    • SessionsCommitted - Counts the number of times a session is commited to the provider (again, happens on each request)
    • We can't track abandoned or timed-out sessions any more as they are handled by caching now and we don't provide a way to explicitly abandon a session. We could detect "empty" sessions (with no data) but such a session could always be added to again later.

See https://gist.github.com/anurse/af1859663ac91c6cf69c820cebe92303 for some guidance on adding EventSources and EventCounters to ASP.NET projects.
