CPT Calculator ArcGIS Desktop feature service access with cached basemap tiles
Figure A1-9a.5 CPT Calculator ArcGIS Desktop connection to ArcGIS Server feature service workflow with cached basemap.
Figure A1-9a.5 shows ArcGIS Desktop connection to ArcGIS Server feature service workflow with local cached basemap files. This workflow can be used with raster basemaps and with vector tile maps. This workflow assumes a percentage of the map display is provided by pre-cached tiles, and these tiles are downloaded to the local client for mashup with additional dynamic feature service layers. Client, network, and server processing loads are reduced based on the percentage of display that is cached.

Creating a tile cache workflow performance target.

  • Select Software technology performance factors for AGDwkstnFSvc workflow (Cell E3:F3) based on display complexity.
  • Select percentage of display (%DataCache) supported by cached basemap tiles (Cell F6).
  • Select +mapcache (cell K5) to account for tile download traffic. This assumes basemap tiles are downloaded once, and follow-on requests for the same tiles based on map extent will use local cached tiles.
  • Tiles are cached in local client internet browser cache. Local browser file cache can be deleted to refresh basemap tiles.

Creating an ArcGIS Desktop Web GIS workflow with client feature caching
  • Select Software technology performance factors for AGD wkstn$ FSvc (Cell E3:F3) workflow based on display complexity.
  • Select percentage of features (%DataCache) cached on the client workstation (Cell F6).
    • Cached features are downloaded once.
    • follow-on requests for cached features use local feature cache.
    • no network or server query loads when accessing local cached features.
    • Feature edits will clear local feature cache (feature cache refreshed from service queries).
    • Percentage of features in local cache (%DataCache) will vary based on the client workflow.
How caching works
  • ArcGIS Pro uses a cache to optimize performance when working in previously visited extents.
  • When working with web feature layers there are only two options for caching: Clear the cache when the session ends, or Do not cache.
  • Branch versioning. When the web feature layer has been published and the version management service (VMS) capability is enabled the edit application manages the cache. In this scenario the option to use the cache and clear it when the session ends is enabled by default and cannot be changed.
  • When editing in a named branch version, the cache cannot be cleared if edits have been made but not saved or discarded. Refreshing the version also clears the cache in the case where edits have occurred on the server but are not yet reflected in the current ArcGIS Pro session.

Warning: Limit geoprocessing max instances to allow for dynamic services when both are deployed on the same ArcGIS Server site.
Workflow separation best practice: Batch geoprocessing services are best supported on a dedicated ArcGIS Server site.


CPT Calculator ArcGIS GeoEvent Server

GeoNet GeoEvent blog

The ArcGIS GeoEvent Server supports a variety of real time ingestion and streaming services. CPT Calculator Software Technology Performance Factors (Software, Graphics, Density/Portal, Complexity, %DataCache, Resolution, and Output) can be selected to generate performance targets for a variety of GeoEvent Server event ingestion capabilities.

GeoEvent Server supports two different service capabilities.

  • GeoEvent Ingestion. Event inbound traffic and processing loads on GeoEvent Server.
  • GeoEvent streaming services. Event traffic streaming or messaging to client displays.
Warning. GeoEvent streaming services traffic can cause network contention.
Note. Based on ArcGIS 10.5.1 and prior releases. ArcGIS 10.6 provides a more scalable ArcGIS GeoEvent architecture.

ArcGIS 10.5 GeoEvent Server

Figure A1-9a.22 CPT Calculator ArcGIS 10.5 GeoEvent Server for real time event collection (ingestion) services.

Figure A1-9a.22 shows the CPT Calculator ArcGIS 10.5 GeoEvent Server configuration for real time event collection (ingestion) services.

The following CPT Calculator Software Technology Performance Factors are appropriate for GeoEvent ingestion loads (GeoEvent Server capacity planning).

  • Software Source = GeoProcessing (Cell E2).
  • Software = AGS GeoEvent (Cell E3).
  • Output = Feature. Inbound real time vector traffic (feature transactions).
Warning. GeoEvent Server ingestion load is based on ArcGIS 10.5 medium complexity capacity planning expectations (relatively simple event processing loads).

CPT Calculator peak throughput Requirements settings.

  • Min Think = 0.01 (Cell D6). Inbound event traffic can approach 4000 transactions per second (no think time). Important to set Min Think time > 0 for CPT to include random arrival wait (queue) times.
  • User = number of GeoEvent sources. Enter number of real time locations/vehicles (clients) being tracked.
  • DPM/client = average client transmission rate (B6). Enter client transmission rate (i.e. 60 transactions per minute/client) to generate peak throughput rate (Cell U6).

GeoEvent peak throughput rate may be limited by one of the following non-CPU intensive constraints.

  • RabbitMQ max throughput 4000 events/sec.
  • Maximum geofences must fit in physical memory.
  • JVM memory default may need to be reset to extend memory access.
  • DDR3 RAM max memory speed of 800-2133 MT/sec.
  • DDR4 RAM max memory speed 2100-4266 MT/sec (GeoEvent Server may require DDR4 memory to support peak throughput).
Best practice. GeoEvent Server should be deployed on single machine sites - multi-machine sites do not scale due to very light inbound event transaction loads.
Workflow separation best practice: GeoEvent Server must be deployed on a dedicated machine.

ArcGIS 10.6 GeoEvent Server

Figure A1-9a.23 CPT Calculator ArcGIS 10.6 GeoEvent Server for real time event collection (ingestion) services.

Figure A1-9a.23 shows the CPT Calculator ArcGIS 10.6 GeoEvent Server configuration for real time event collection (ingestion) services.

Beginning with the 10.6 release – GeoEvent Server is running an Apache Kafka instance as an event message broker within the ArcGIS GeoEvent Gateway Windows service. The message broker uses on-disk topic queues to manage event records. The event records which have been sent from the message broker to a GeoEvent Server instance for processing are recorded within the broker's associated configuration store (e.g. Apache Zookeeper).

The Kafka message broker provides a transactional message guarantee that the RabbitMQ message broker (used in 10.5.1 and earlier releases) does not provide. If the GeoEvent Gateway on a machine were stopped and restarted, the configuration store will have recorded where event message processing was suspended and will use indexes into the topic queues to resume processing previously received event records.

The CPT Calculator configuration for the ArcGIS 10.6 GeoEvent Server is similar to earlier releases.

  • Software Source = GeoProcessing (Cell E2).
  • Software = AGS 10.6 GeoEvent (Cell E3).
  • Output = Feature. Inbound real time vector traffic (feature transactions).
Warning. AGS 10.6 GeoEvent Server ingestion load is based on medium complexity capacity planning expectations (relatively simple event processing loads).

CPT Calculator peak throughput Requirements settings.

  • Min Think = 0.01 (Cell D6). Inbound event traffic can approach over 12,000 transactions per second (no think time). Important to set Min Think time > 0 for CPT to include random arrival wait (queue) times.
  • User = number of GeoEvent sources. Enter number of real time locations/vehicles (clients) being tracked.
  • DPM/client = average client transmission rate (B6). Enter client transmission rate (i.e. 60 transactions per minute/client) to generate peak throughput rate (Cell U6).

GeoEvent peak throughput rate may be limited by one of the following non-CPU intensive constraints.

  • Kafka message broker max throughput is much higher than previous releases. Maximum test ingestion rates exceeded 12,000 events/sec.
  • Maximum geofences must fit in physical memory.
  • JVM memory default may need to be reset to extend memory access.
  • DDR3 RAM max memory speed of 800-2133 MT/sec.
  • DDR4 RAM max memory speed 2100-4266 MT/sec (GeoEvent Server may require DDR4 memory to support peak throughput).
Workflow separation best practice: GeoEvent Server sites must include an odd number of machines (i.e. three machine site) for optimum failover recovery.

CPT Project Workflows
