Oops - Dennis got a response posted while I was writing mine. Thanks Dennis! Hello Debra  - Can you please confirm the version of GeoEvent Processor you are installing?  With the 10.2.1 product release the Service Designer was retired and the functionality for designing and publishing GeoEvent Services was incorporated into the GeoEvent Processor Manager. We are working on updating the "Intro to GeoEvent Processor" tutorial to reflect the changes to the product. We will be posting the updates to the product gallery as soon as possible. Thanks - RJ ...

Hello Ayman "? If the event count for your Input polling ArcGIS Server for Features is not indicating that any features are being received, this is usually because an existing event definition does not match the data being received so the Input"?s adapter is not able to create a GeoEvent. I opened your map document from the map package you posted. None of the feature coordinates contain null values, but I did notice that several hundred of the UNIT_DBID attribute values were null. I used ArcMap"?s field calculator to assign those value to -1, just so that all of the features and attributes would have valid non-null values. I published the map document to my local ArcGIS for Server as a map service with feature access enabled (so I have a feature service as well). In GeoEvent Processor I created a new Input "?Poll an ArcGIS Server for Features"? with the following configuration. [ATTACH=CONFIG]30956[/ATTACH] The Input fs-poll-in immediately received 804 new events "� and every 60 seconds another 804 events were polled from the feature service. The GeoEvent Definition generated for the events looks like: [ATTACH=CONFIG]30957[/ATTACH] Note that you do not need to incorporate the Input in a GeoEvent Service or send event data to an Output to verify that an Input is able to poll ArcGIS Server for features. I would recommend using GeoEvent Processor Manager to delete the Input, GeoEvent Service, and Output you have created. Also delete any generated GeoEvent Definitions you have created for this data. Make sure that a newly created Input is able to create a new GeoEvent Definition. Be aware that the JSON adapter - the component used by the Input to interpret the data being received -  will generate a GeoEvent Definition based on the content of the first event received. The adapter will omit any fields from the GeoEvent Definition whose value is null. This is the behavior at 10.2.1 "� we are looking at changing it at 10.2.2 so that the fields will be created even if the attribute value in the first event received is null so that the generated GeoEvent Definition matches the schema defined by the feature service being polled. Hope this helps - RJ ... View more

Hey Dennis - We've taken note of the limitation with regard to event data not making it into the intended feature class due to incompatibles with the feature class"?s properties. We"?ll see what we can do to have GEP generate some sort of warning or error message "� What you are experiencing, though, is consistent with the design of Outputs in general. The GeoEvent Service will send a GeoEvent to an Output, and if the Output is able to use its adapter and transport to successfully dispatch the event, then it"?s done its job. If the XMPP Server, Email daemon, Web Server, ArcGIS for Server (etc.) are unavailable it"?s like you posting a letter but the Post Office failing to deliver it. GEP has done what it can do, but it cannot guarantee that an Instant Message or Email (for example) was successfully delivered. There are steps you can take to help insure event data is prepared for receipt by a feature service. If you suspect it likely that a data provider will be sending integer values which exceed the 32-bit range of an esriFieldTypeInteger (which corresponds to a SQLServer signed int) "� since GEP supports 64-bit long integer values "� you could configure a filter to direct values which won"?t survive entry into the feature service to send the event data to a system text file. Pairing the filter with a field calculator, you could even enrich the event with your own error text so that, reading the text file, you would know which events didn"?t get created as features (and why). Similarly with strings whose length is too long for your feature layer"?s field "� you could use a regular expression such as ^.{0,32} in a Field Calculator (Regular Expression) to truncate strings to a fixed length (in this case 32 characters). This will become easier with the string functions being supported in the regular Field Calculator with the 10.2.2 product release. I think I"?ll work that example into the Intro Tutorial "� using a regular expression to trim a string"?s length. I kind of like that "� Hope this helps - RJ ... View more

Hello Vassilo - To manage the carriers, you will need to edit the com.esri.ges.transport.sms.cfg file found in the ...\GeoEventProcessor\etc folder in the product's installation folder. The Windows default is C:\Program Files\ArcGIS\Server. After editing the file and saving your edits you will need to restart GeoEvent Processor. The first line of the file specifies the carrier names: com.esri.ges.transport.sms.carrierNames = Verizon, T-mobile, Sprint, ... The second line of the file specifies the domain (or SMS Gateway) used by the specified carriers: com.esri.ges.transport.sms.carrierDomains = @vtext.com, @tmomail.net, @messaging.sprintpcs.com, ... You will need to find out if your carrier(s) offer public / free SMS gateway access, and if so, get their gateway domain (e.g - @vtext.com).  Doing a quick search online, we have found a list of SMS gateways on a Wikipedia page - https://en.wikipedia.org/wiki/List_of_SMS_gateways ... but we cannot tell you whether or not Wikipedia is up-to-date. - RJ ...

Hello Dennis - I don't see anything wrong with the JSON sample you posted. I was able to create a basic 'Receive JSON on a REST endpoint' Input and POST the sample to the GeoEvent Processor Input's REST endpoint. Configuring my Input as shown in the first illustration below, I allowed a new GeoEvent Definition to be created. I've included an illustration of the generated GeoEvent Definition below. When I post the JSON, I get two events received. I can output those to a system text file as JSON without any problem. I noticed that in the second record, the one whose driverID is 83886089, a few of the fields are null. If I delete the GeoEvent Definition and then swap the order of the events in the list so that the record with the null attributes is first ... the generated GeoEvent Definition does not contain fields for the attributes which were initially received as null. I'm not sure, but it might be that you have a GeoEvent Definition which does not match the content discovered by the Input connector, so it discards the event it cannot recognize. That would explain why you are observing the event count not incrementing. You might try deleting your existing GeoEvent Definitions and seeing if the Input is able to create a new one based on data it receives. The only other piece to the configuration that I notice is that your connector, aside from specifying connection credentials and a polling frequency, is specifying a 'Parameters' value of 'minutes=1440'. I'm not sure what that parameter is, or it is plays into the issue. - RJ ... View more

Hello Chen - I'd like to make sure that I understand your question. Are you working with a single data stream and need advice on how to manually configure a cluster of GeoEvent Processor instances which will work collectively to pull and processing individual events from the high volume data being received?  Support for high-availability and clustering are concepts being developed for the "11" product release which will feature a new type of stream service input. We are working to make this functionality available later this year. It may be possible to manually configure high-availability and clustering for the current 10.2.1 product release - but it depends on what exactly you are trying to accomplish. If you are working with several different (independent) data feeds, you can scale your site architecture by installing additional instances of GeoEvent Processor onto the GIS Servers in your ArcGIS for Server site. You would simply need to make sure that each instance of GeoEvent Processor had its own Inputs, Outputs, and GeoEvent Services. - RJ ... View more

Hello Zubair - The GeoEvent Processor Simulator reads text files containing simulation data generally expressed in a comma separated format. It is also capable of connecting to your local ArcGIS for Server site and retrieving data from a feature layer to use to simulate events. Please refer to the instructions included in the Introduction" rel="nofollow" target="_blank">http://www.arcgis.com/home/item.html?id=265c334a47994dcc95e1bd57cf20e98e]Introduction to GeoEvent Processor tutorial available from our Product" rel="nofollow" target="_blank">http://www.arcgis.com/home/group.html?owner=GeoEventTeam&title=ArcGIS%20GeoEvent%20Processor]Product Gallery for additional help with using the GeoEvent Processor Simulator. The development team is not in a position to make recommendations with regard to commercial services or equipment providers for compiling GPS data. If you are looking for sample simulation files, we have some included with the Introduction to GeoEvent Processor tutorial ... just download that tutorial package and you can extend the sample simulation data you find there to meet your needs.

Hey Mark - Sorry for the delay in getting back with you on this. If I restart my xmpp server the instant message outputs do not work again until I restart the output. Is the instant messaging output supposed to automatically reconnect to the xmpp server? Looking at the implementation, no, the Output is not going to automatically attempt to reconnect to the XMPP server if the server is taken off-line and later comes back on-line. This is probably a functional gap that we should address, since the Output remains in the 'Started' state and there is no indication to the user that the Output needs to be stopped/restarted. Is there any way to tell them to try to automatically reconnect or some other way to deal with this? Is there any way to tell if an IM output is not connected? No, there is no indication through GeoEvent Processor Manger that the Output needs to be cycled or that it is not connected to the XMPP server. As part of the enhancements for the 10.3 / 11 product release we can look into having the Output determine its server connection status when a GeoEvent is received, attempt to reconnect if not connected, and log an error if a connection to the server cannot be realized. This would improve reliability. The only work around currently available to you would be to develop some sort of "status monitor" as a JavaScript which would begin polling the server to see if it was available (after detecting that it had been shut down) and then command the GeoEvent Processor Output to restart through the component's administrative REST endpoint. I am using openfire XMPP server and it requires the chat room to be configured before anyone else can join. Configuring a chat room appears to be something that is defined/required by the XMPP RFC/spec. Is there anyway to handle chat room configuration with the IM output? No, implementing the Output to handle chat room creation and configuration is not supported. We had initially considered this, but had to limit the scope of the development. The XMPP connector was intended to highlight the potential for event notification via Instant Messaging. We decided to leave creation and configuration of chat rooms to the XMPP server administrator. We identified quite a few potential configurations with regard to chat rooms using different varieties of XMPP servers and couldn't commit to support this with the initial product release.

You also might try getting the GeoEvent Service configuration to a working state on your Win7 machine, then exporting the GeoEvent Processor's configuration from the Site > GeoEvent Processor > Configuration Store page, and importing the XML into a clean instance on your Win2008 R2 machine. An easy way to clear out the configured elements (Inputs, Outputs, GeoEvent Definitions, etc.) is to stop the Windows service running GeoEvent Processor, locate and delete the files from the C:\ProgramData\Esri\GeoEventProcessor folder. I would recommend leaving the ...\certs folder so that you don't have to re-import the SSL certificate as trusted. Also, if you are running 10.2.0, be sure to leave the ...\connectors folder (this will be rebuilt for you if you're running 10.2.1). If you find that a more aggressive cleaning is needed, you can locate and delete the C:\Program Files\ArcGIS\Server\GeoEventProcessor\data folder to remove any cached elements; the folder will be rebuilt when you restart the Windows service. As long as both machines are running the same version of GeoEvent Processor, you should be able to share configurations this way so that you don't have to reconfigure Inputs, Outputs, GeoEvent Definitions, and GeoEvent Services. There's a lot of touch points you have to make sure you've replicated on each box ... and forgetting something simple like a GeoEvent Definition or tagging a TRACK_ID onto a event definition field can easily make it look like one server is working and the other isn't. - RJ ...

Hello Luis - What you are observing is by design. The adapter used with the TCP/Text Output connector reports date/time values using your local system's locale. I'm in the Pacific Time Zone (California, USA) and using the GeoEvent Simulator's feature to 'Set value to Current Time' I can insert the local system date/time into events as they are sent into GeoEvent Processor and observe "local time" values displayed as text in either a CSV system file or as text via a TCP Socket. When I output the event data to a TCP socket using the 'Publish text to a TCP Socket' Output connector, and use the use the TCP Console application to  observe a text representation of the data, I see my local system's date/time. The 'Text' adapter has converted the date/time object within the GeoEvent to a text representation. When I output the event data to an ArcGIS Feature Service, the GeoEvent's date/time object is handled by the JSON/FeatureService adapter and transport. The date/time representation in the feature service is a Long Integer recording the number of milliseconds since midnight 1/1/1970 UTC. If you query the REST endpoint of your feature service to obtain this Long Integer value and use a conversion utility such as http://www.epochconverter.com/ you should find that the value obtained from the feature service can be converted to a GMT value as well as offset to your local time zone. It's all about what client you are using to view a representation of the date/time, and how that client is converting the event data it receives in order to display it for you.

Hello Hiro - No, there's no known issues with the sample server. I was able this morning, using my 10.2.1 configuration, to create a new input using the web socket endpoint (ws://geoeventsample1.esri.com:8080/exactearthservice) we've been referring to in this thread. Are you able to reach the HTTP endpoint through a browser? Please take a look at the debugging steps outlined in my reply on 21-Nov-2013 in this thread above. You might be able to obtain some additional information on why the connection is being refused if you're able to step through the JavaScript using the Chrome developer tools. I was able to visit the demosite page (http://geoeventsample1.esri.com/demosite) on a mobile device and connect to the ExactEarth Vessel Tracking service sample from there. - RJ ... View more

Hey Adam - I have opened up a GEP Service to edit it in IE9 and Chrome. The screen remains blank and locks up in IE9. Everything works in Chrome... If you'd like, I can take a look at the GeoEvent Service's layout and properties if you export the XML configuration and send it to me. You're observing this using the 10.2.1 release? Have you tried clearing the IE browser cache, logging-out and back into Manager? There was a security feature added to 10.2.1 which automatically logs you out after 1 hour. The time is configurable from within a product config file if the log-out is getting in your way. I've sometimes seen odd behavior when my session has expired and I try to do something like open a GeoEvent Service for editing. I am not able to delete a connector line between inputs, processors, filters and outputs. For example, I want to insert another processor in the middle of the Service between two others I wish to keep. How do I eliminate the original line? We can look at adjusting the pixel tolerance if it's proving difficult to select a connector line. You should be able to click the line (it will highlight/glow when selected) and press 'Delete'. I also miss being able to copy and paste processors (or even just equations or lists) from one service to another and just selecting a tab to get back and forth between services. We will look into being supporting copy/paste of user entries from the different properties panels. I think the feature was added to the 10.2.2 release (due out March / April) to copy service elements such as processors and filters within a service, but you still won't be able to copy them from one service to another. As far as working with tabs ... can  you try using the Browser's tabs, effectively opening a new window, and working on the two services you want to edit that way? Please let me know if that works for you. Thanks - RJ ... View more

Hey Dennis - There are known issues when using IE8 to launch the GeoEvent Processor Manager.  If I remember correctly, these centered around registering Data Stores with the 10.2.0 product release. I will see what I can do to evaluate 10.2.1 Manager behavior under IE8. It's possible, given the diagnostics you provided, that there is something relatively easy we can identify for the 10.2.2 product to better support the older browser. But please know that Esri Support recommends users upgrade to either IE9 or IE10 when running Server Manager. GeoEvent Processor is using the same technology for our Manager, so we are going to have to make the same recommendation.

Hello Mark - Does the field enricher work with GUID fields No, the Field Enricher processor has restrictions on which fields can be used to join the event's table/schema to the enrichment's table/schema. Currently the field type in the published feature service must be one of esriFieldTypeInteger or esriFieldTypeString. (The data type esriFieldTypeSmallInteger may also work, but I've not been able to verify that). I'm trying to create Geo fences that use the guid as the name and then do a field enricher join based on the guid to append data from the geo fence. I'd recommend that you try using a Field Calculator to create a String equivalent of your GUID in a new field. You might then be able to join the event's STRING to an enrichment table's GUID. If that does not work you'll have to rework your event data and the attribute data of your GeoFence to use Strings and Integer values for enrichment. - RJ ... View more

Hey Dennis - Thank you for your effort in preparing  the JSON representation of your input and event definition. As it turns out, this issue is much easier to reproduce than I initially thought. I"?ve replicated it in Chrome as well as Internet Explorer 9 and 10. This will be a known issue for the 10.2.1 release. We are looking to address the issue in the 10.2.2 product release which should be publicly available late Q1 or early Q2 this year. I"?ll include some screenshots below, for those who discover this thread later, but the work around (as you discovered) will be to <tab> to reveal any input fields missing from the display. You can also use your mouse"?s scroll wheel to scroll further down than what the vertical scrollbar on the property panel currently allows. The issue is that the pop-up dialog containing the configurable properties has a couple of static portions and a dynamic portion in its layout. You can use your mouse"?s scroll wheel to scroll through the dynamic "frame"� within the property panel. Consider the screenshots below "? the area dashed in red is the "dynamic"� portion of the property panel. Changing the processor type from "?Field Calculator"? to "?Field Mapper"? changes the content in the middle of the panel. When I select a GeoEvent Definition with more than a few fields (such as the product"?s incident event definition) the dynamic part of the panel runs past the panel"?s bottom edge. I can either <tab> through the fields in this portion of the display, or use my mouse"?s scroll wheel to scroll and reveal the remaining input fields. This obviously needs to be fixed since using the scroll bar to scroll to what you think is the bottom of the panel doesn"?t work. You could of course try maximizing your browser window to provide more real estate for the Manager and the pop-up properties panel "� but this may not be an option depending on screen resolution or if the size of your browser window is limited by a VM management console.
