GeoEvents Maxing out ArcServer Connections>?

Have Vehicle and Aerial Resources over TCP -- get about 2-3k events fire and start to see a performance hit on the AGS.

Internal Server Error. Wait time of the request to the service

  'WRMS/AVLService.MapServer' has expired.

Ultimately See the Server Coming to it's knees -- feel like I have read all of the docs and tut's confidence is high that in GEP things are configured correctly--am I missing something in AGS>>>??

Any Ideas ??

GEP doesn't support versioned database.

Based on our experience, AGS will max out around 300-500 features per second. If the 2-3k events are per second then this is well over the typical limit. You may want to consider using a Load Balancer on the AGS side or hardware sizing (e.g. increasing RAM, applying storage solution).

Morakot Pilouk,

If end-user visualization is Brian Locke‌'s main concern, could streaming via the new WebSocket survive this number of events/second? I know that there is no Esri COTS end-user app currently configured to accept this feed, but one would hope that the Operations Dashboard for ArcGIS and the new Web AppBuilder for ArcGIS would soon get on the bandwagon!!!

Yeah I have simulated the events at 2 every second 1 every second and one at 1 every 5 seconds-- still the same result

It when I hit the 2-3k total events is when I start to see the performance issues

So I have a TCP input that with the GeoEvent Definition being the first parameter.  within my service I have a filter that uses the $DEFINITION_NAME tag to check for what Feature service it should update.  I then have three 3 Feature Services that are all under the same service

Should I be separating out the different feature services to their own service or can I keep them all under one>?  Must admit going on weeks and weeks of tweaking about to give up on GEP-- Seems like anytime we try and use it AGS takes the hit and brings the entire enterprise downUntitled-2.png

Brian,

I have never had any luck with multiple layered feature services and GeoEvent‌ Extension.

I know that isn't a specific answer; just my experience.

If you are simulating only 2 every one second and it isn't working, I am pretty sure that is your problem.

I don't think you HAVE to separate the different groups of events if you don't want to. It probably really depends on how you want to utilize the services on the visualization end.

Yeah Copy that I think  that I will go about and separate these out see if I get better results, thanks a million.

Yeah I have the same issue with another service but it is updating only one feature service so I don't think that is the issue... Still scratching my head thinking about submitting an issue to ESRI

Kinda shooting from the hip here...

Is ANYTHING versioned in the GDB?  That will cause problems.
