Mapservice in AGOL Dashboard App Painfully Slow

MichaelVolz — Thu, 11 Dec 2014 18:05:13 GMT

To All AGOL Users:

I have an AGOL Dashboard application that is consuming a hosted mapservice (quite simple) that is used simultaneously in multiple widgets. The mapservice performance in the Dashboard app as well as at the REST endpoint is painfully slow. Has anyone using the AGOL Dashboard app encountered this issue? If so, how were you able to resolve the issue.

Hi Mike,

Do you add the map service only once in the web map and build operation view using operations dashboard app, and consume the same map service in multiple widgets? If so, the performance shouldn't be low. You mentioned that the map service REST endpoint is also slow, so I am wondering if the performance issue only happens on this specific map service, or other map services as well?

I would like to get more information and see if we can nail down the problem.

Thanks

Jay:

The hosted mapservice was originally configured to be run in high isolation with a minimum of 1 instance per machine and a maximum of 2 instances per machine. There was terrible performance so the maximum instance was bumped up to 4 instances.

The mapservice was then configured to run in low isolation with 4 instances, but I have not gotten any feedback on performance of this modified mapservice.

Do you think these parameter changes would have an impact on the mapservice performance in the AGOL Dashboard app?

Are there any other changes that you would suggest?

Any help or hints are greatly appreciated.

Thanks for the information Mike.

As the first step, I would like to isolate the issue to see if this is caused by the map service itself or it's by the operations dashboard app. From your information, it seems if REST end point of the map service is having performance issue, that's the first place to take a closer look. I do not work with Server team, but from my experience, increasing the max number of instances might help. The other place to take a look is the server log. If you enable verbose mode and check server log, it can often tell you something.

Hi Mike,

I touched base with server team and based upon the information you provided, the map service sounds more like an on-premise ArcGIS Server map service because hosted map service in ArcGIS Online or Portal are typically tile-only services and hence do not have min-max instances.

If you can confirm this, I might be able to see if they have any specific suggestions that you can try out for improving performance.

Thanks

It is a hosted on-premise dynamic mapservice whose back-end file geodatabase is getting updated every 5 minutes from a live data source.

Jay:

Does it make sense that a Dashboad app in AGOL that has 7 widgets that are polling a file geodatabase on a county hosted server every 30 seconds would spin up 7 instances to get the data for each widget? In addition, the file geodatabase on a county hosted server is itself being updated every 5 minutes.

Did you add each layer from your map service individually or did you add the service all together? I have found some performance issues when adding each layer from my map service individually as opposed to adding the map service itself.

Reynald:

The widget is using the same layer from 1 mapservice just configured in different ways to produce different results that are useful to management to accessing the conditions.

In you Dashboard app, did your mapservices originate in AGOL or were they being consumed from your organization's own ArcGIS Server environment?

Hi Mike,

Do you mean 7 instances of AGS service or ops dashboard instances? For ops dashboard, you should only see one instance in Task Manager.

I mean 7 instances of AGS service.

Is there any chance I can open an ESRI incident with you on this issue and you already have some background information about the issue?

Re: Mapservice in AGOL Dashboard App Painfully Slow

The map service is from our ArcGIS Server.

Reynald:

Are you using the AGOL portal or are you using your own organization's portal?

Are you saying that I should avoid using feature services where I bring in each layer individually from a mapservice instead of the entire mapservice all at once?

Re: Mapservice in AGOL Dashboard App Painfully Slow

Reynaldde_Castro — Mon, 22 Dec 2014 19:29:29 GMT

I am using our organization's portal.

Yes, I found that adding the individual layers from a map service yields to slow performance compared to loading the entire map service.

Reynald:

The mapservice is sourced from a file geodatabase on a file share that is registered with ArcGIS Server. Is your mapservice sourced from a file geodatabase, SDE, etc.?

The mapservice performs fine until the file geodatabase is updated from a python script where the feature class records are deleted and then added in again. When this process is running on a 5 minute interval, the mapservice has severe performance issues. Do you think sourcing the mapservice from SDE would resolve this performance issue?

Re: Mapservice in AGOL Dashboard App Painfully Slow

Reynaldde_Castro — Tue, 23 Dec 2014 17:19:59 GMT

Potential issue would be network when serving from a file geodatabase and especially when you are running updates every 5 minutes. How big is the dataset that you are updating? Are you updating attributes only or both (geometry and attribute)? If you are updating attributes only then there would not be a need to replace the entire feature class.

Is the map publically accessible?

Re: Mapservice in AGOL Dashboard App Painfully Slow

MichaelVolz — Tue, 23 Dec 2014 17:30:06 GMT

Reynald:

The dataset currently only has 29 point features, yet it locks up the mapservice.

Do you think there are file geodatabase locks that could be causing the problem, which would go away if the data was sourced from SDE?

Reynaldde_Castro — Tue, 23 Dec 2014 18:08:38 GMT

Let me take a step back....the dashboard is using a webmap published to your AGO site. The webmap is using hosted feature layers within your AGO that is updated from a file geodatabase. The hosted feature is updated every 5 minutes.

Is that right?

Re: Mapservice in AGOL Dashboard App Painfully Slow

MichaelVolz — Tue, 23 Dec 2014 18:14:31 GMT

Reynald:

Since you told me that individual feature services would create performance issues, I add a mapservice from my organization's ArcGIS Server to a web map in AGOL as the mapservice is publicly accessible. This AGOL web map is then used in the Operations Dashboard app. The mapservice itself originates from an AGS registered file geodatabase that is updated every 5 minutes from a python using an XYeventlayer where all features are deleted and then added.

How do you update the data for your service that is used in the web map for the Operations Dashboard app?

Re: Mapservice in AGOL Dashboard App Painfully Slow

Reynaldde_Castro — Tue, 23 Dec 2014 19:41:37 GMT

Did the performance of the map service improve? I created a hosted feature layer on our AGO site and update that. The feature is used as the datasource for the webmap.
