Hi @JoshBillings thanks for the question. Posting a link from the documentation below and adding some thoughts on the end. How is ArcGIS Velocity different from ArcGIS GeoEvent Server or ArcGIS GeoAnalytics Server? ArcGIS Velocity differs from ArcGIS GeoEvent Server and ArcGIS GeoAnalytics Server in many ways, including product capabilities and business model. On a high level, GeoEvent Server and GeoAnalytics Server are on-premises software, while Velocity is a software-as-a-service (SaaS). Other differences include the following: Velocity has built-in high availability and disaster recovery. Velocity is deployed automatically, taking only 30-60 minutes to get access. Data stored by Velocity is stored in the cloud. Velocity is not directly extensible due to its nature as a SaaS. Velocity is geared toward operations and geospatial analysts as opposed to just GIS administrators. Velocity is offered via a subscription as opposed to a software license. Additionally: Velocity has a redesigned and updated user experience including analytic validation that will protect the user from misconfiguration Velocity offers big data analytics to process data sources that can contain anywhere from small amounts of data to hundreds of millions of features Velocity offers the use of easily configurable Arcade expressions in multiple tools including Calculate Fields, Map Fields, and other tools Let me know if you have any follow-up questions on the differences

@JeffSilberberg Yes, there is a realtime module for the ArcGIS API for Python with start() and stop() methods for a real-time analytic https://developers.arcgis.com/python/api-reference/arcgis.realtime.html#realtimeanalytics

Thanks for posting this question, this is something we continue to consider from the product side. As you have found, when designing a real-time analytic, for some data inputs you need to choose between configuring this as a feed or as a source. Sources only go fetch the source data when the real-time analytic is started or restarted. Therefore, if your real-time analytic is started, and sits there running for weeks, it is evaluating against data that is hours to days to weeks old. This is by design, and expected to be used for something relatively static. Think zip codes, census block polygons, and such. Whereas with feeds, you can configure a polling interval for polling type feeds such as feature layer feed or HTTP poller feeds. This can be as frequent as every 10 seconds, to much less frequent such as every 1 day or every 12 hours. However, you advised this did not work. Please feel free to log a support ticket for assistance. But also be aware, if you start the real-time analytic referencing these two feeds, data will not be available from this "every 23 hour" join feed until it hits its polling interval. What quite possibly is happening is that you started your real-time analytic but the secondary feed has not yet pushed any data into the real-time analytic for evaluation as the polling interval has not yet been encountered. Instead of refreshing that feature layer feed every 23 hours, I would suggest setting something between every 30min - every 2 hours. For a longer term product perspective, we are investigating enhancement possibility to enable real-time analytic source data refresh without having to restart the analytic.

Why add administrative contacts? As a cloud-native add-on capability for ArcGIS Online, ArcGIS Velocity enables users to build feeds and analytics to ingest, analyze, and process real-time data. In addition to these powerful features, ArcGIS Velocity also leverages the ArcGIS Online administrative contacts functionality. This enables users to notify organization administrators about a number of ArcGIS Velocity scenarios including: Scheduled updates including the scheduled upgrade time window Upgrade or maintenance completion Compute and storage capacity related notifications Important notifications requiring user or administrator attention. For example, feed or analytic inability to reach an item dependency such as a source feature layer. By expanding notifications beyond a single person, ArcGIS Velocity's use of administrative contacts provides a seamless method to keep key stakeholders informed about essential information. Through this alerting of relevant contacts, organizations can mitigate downtime and ensure smooth operation of their real-time and big data analysis flows. How to add administrative contacts: To add administrative contacts to receive ArcGIS Velocity notifications, first log in to ArcGIS Online as an organization administrator Click the Organization tab Select Settings Review the General tab Find the section Administrative contacts Choose and add the administrator or administrators who will be listed as points of contact The specified administrators and their email addresses are then listed as points of contact in the automatic email notifications sent to organization members when the Velocity organization. In addition to these specified administrators, relevant users are independently notified for scenarios such as item or authentication alerts that trigger notifications. Below you can see an example of an ArcGIS Velocity upgrade notification that is sent out to notify prior to an upgrade window. By adding organization administrators to the administrative contacts element, these additional administrators will also receive these notifications among others. Interested in learning more? Check out the other ArcGIS Velocity blogs and read more about relevant administrator information in the product documentation. You can also learn how to get started with ArcGIS Velocity using this Learn ArcGIS lesson. Please reach out and let us know if you have any questions about any capabilities in ArcGIS Velocity.

Hello @ArmstKP! there were lots of user interface changes with our recent release that went out last week. Please clear your browser cache and reopen Velocity in a new tab. If the issue persists please log an Esri Support Services case for the reported issue for assistance and a workaround if needed. Thanks!

‎05-03-2023

@Jim_Wei If you ever witness a feed or analytic go down and stop functioning as expected, please make sure to log an Esri Support Services ticket so the root cause can be addressed by the product team. A combination of Map Fields to designate the relevant Track ID field with Detect Gaps > Control Event Volume can be used to limit the number of emails sent in the event of features coming through that pipeline. The ArcGIS Velocity product team is committed to continuing to enhance product level notifications and alerts and we will take this request under consideration. In the meantime, a feed configured on your output feature layer with Detect Gaps > Control Event Volume in a separate real-time analytic would achieve the core goal of automatically notifying if features are not flowing as desired and be contained in separate elements from your processing analytic.

@SimonGIS Thanks for your post and for raising this need! Currently the ArcGIS Velocity WebSocket feed type does not support authentication. I have entered an item on our side for the Velocity team to research expanding this functionality to offer a user-configurable JSON subscription message as well as exploring other authentication options to expose for this feed type.

@WilliamKeever As an update, I have been in communication with Verizon about this enhancement/idea request. While the Verizon web application currently supports groups, there is enhancement still needed on the Verizon side to make the group field available through the underlying communication component. Because the ArcGIS Velocity Verizon feed type depends on this underlying communication component, we cannot add this feature until it is present on the Verizon side. We will remain in contact with Verizon and explore adding this functionality when the requisite enhancement is made by Verizon.

@AW_Grove From the Velocity side, ArcGIS Velocity does not use credits and is instead operates on a subscription model. ArcGIS Velocity can write to multiple output feature layer types: ArcGIS Velocity layers - do not use credits ArcGIS Online hosted feature layers - there is a credit consumption associated with these type of layers, see this documentation for more details on that ArcGIS Enterprise layers - do not use credits From the Velocity side, we will be investigating the pathway to add the group field for Verizon Connect Reveal, thanks for adding this idea!

@ArmstKP Thank you for raising this issue with us, we are actively investigating. Can you please log an Esri Support case for tracking purposes? This will let Velocity product and operations team know which organization you are working with to facilitate resolution.

Thanks for submitting this idea, we will consider this in future product direction planning

@brudo We had a call with @JeffEismanGIS and @ArmstKP to implement the workaround for the frontend limitation at the current 3.3 release. As soon as 4.1 goes live in late February this limitation will no longer be present. You are correct that in real-time analytics positive values are not valid for backend evaluation, but they are valid for big data analytics. At the current release we do not have a way to insert that nuance to the Arcade expression evaluation but we are considering validation inspection options for future releases. Expect more examples, conference demos, and community videos from the real-time time moving forward on the use of track functions highlighting use cases and configurations. In the meantime feel free to log a support case or direct message a Velocity team member for assistance with the workaround for this negative value specification at the current release.

‎01-26-2023

@ArmstKP @brudo At the 3.3 Velocity release (current) the Arcade expression evaluation code is not capable of evaluating negative index values for Track functions. This shortcoming has already been fixed for our 4.1 release that will go live in production late February. The workaround is to build your expression with positive values such as [1,2], and then to use the Velocity API to modify the value set in the analytic configuration for that expression. For assistance with that process please either create an Esri Support case or reach out to myself or @JeffEismanGIS directly via Esri community direct message to exchange contact information and schedule a call. As soon as our next release goes live in February, this extra step will no longer be required. As an update to this, see @JeffEismanGIS 's edited comment above and @brudo 's suggestion We can use an "if" function determination to assess the array length an if less than 1, we can return a false boolean type and not require any API level modifications prior to the Feb 2023 Velocity update. // Get the prior observation value for the field using TrackFieldWindow var priorValueArray = TrackFieldWindow('driverName', -1, 0)[0]; // Get the current feature observation value for the currentValue field var currentValue = $feature.driverName; // Handle the case where the first value does not have a prior feature // If there is a prior value, determine if the value changed if(count(priorValueArray) < 1){ return false; } else { return IIf(priorValueArray[0] != currentValue, true, false); }
