Use Case: You’ve published a model from Analytics Builder to Analytics Manager, and then used service CreateOrUpdateThingTemplateForModel on resource TW.AnalysisServices.ModelManagementServicesAPI. A thing created from the resulting template will have an infotable called “data” which needs to be populated in order to trigger an Analysis Event & Job. For example you might have been following the online documentation for Analytics Manager > Working with Thing Predictor > Demo: Using Thing Predictor, link here. This script makes it easy to create a line of test data into field "data" on your thing to trigger the analysis event & job. Also fields causalTechnique, goalName and importantFieldCount are set programmatically, these are needed for the analysis event & job. Also this script might be useful as a general example of how to write to an infotable property on a thing. The JavaScript code is shown here and also attached as a text file to this post: me.causalTechnique = 'FULL_RANGE' me.goalName = 'predict_Compressor_failure' me.importantFieldCount = 3 // ThingPredictor.test_3f1a6a31-e388-4232-9e47-284572658a4a.InputParamsdataDataShape entry object //var newEntry = new Object(); var params = { infoTableName : "InfoTable", dataShapeName : "ThingPredictor.test-integer_afebaef3-b2cf-4347-824c-a39c11ddbb4a.InputParamsdataDataShape" }; // CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(ThingPredictor.test_3f1a6a31-e388-4232-9e47-284572658a4a.InputParamsdataDataShape) var myInfoTable = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params); // 2 - CREATE INFOTABLE ROW USING object var newEntry = new Object(); newEntry._Pressure = 10.5; // NUMBER newEntry._Temperature = 45.1; // NUMBER newEntry._VibrationX = 81; // NUMBER newEntry._VibrationY = 65; // NUMBER //newEntry.key = 4; // STRING - isPrimaryKey = true // 3 - ADD INFOTABLE ROW USING TO INFOTABLE myInfoTable.AddRow(newEntry); // 3 – PERSIST INFOTABLE TO THE THING PROPERTY ‘data’ me.data = myInfoTable;

Pushbullet is a lightweight notifications platform and can be a way to explore Alerts and Subscriptions Basically create an an Alert on a property and Subscribe to that Alert Adding Alert to Property Humidity Adding Subscription The PTC-PushBulletHelper is just a generic Thing with a service called PushNotification var json = {     "body": Message,     "title":"Temperature fault",     "type":"note" }; var accessHeader = {     "Access-Token": "o.Hnm2DeiABcmbwuc7FSDmfWjfadiLXx2M" }; var params = {      proxyScheme: undefined /* STRING */,     headers: accessHeader /* JSON */,      ignoreSSLErrors: undefined /* BOOLEAN */,      useNTLM: undefined /* BOOLEAN */,      workstation: undefined /* STRING */,      useProxy: undefined /* BOOLEAN */,      withCookies: undefined /* BOOLEAN */,      proxyHost: undefined /* STRING */,      url: 'https://api.pushbullet.com/v2/pushes' /* STRING */,      content: json /* JSON */,      timeout: undefined /* NUMBER */,      proxyPort: undefined /* INTEGER */,      password: undefined /* STRING */,      domain: undefined /* STRING */,      username: undefined /* STRING */ }; // result: JSON var result = Resources["ContentLoaderFunctions"].PostJSON(params); You can test the Helper PushNotification service Next you can test the subscription

I have put together a small sample of how to get property values from a Windows Powershell command into Thingworx through an agent using the Java SDK. In order to use this you need to import entities from ExampleExport.xml and then run SteamSensorClient.java passing in the parameters shown in run-configuration.txt (URL, port and AppKey must be adapted for your system). ExampleExport.xml is a sample file distributed with the Java SDK which I’ve also included in the zipfile attached to this post. You need to go in Thingworx Composer to Import/Export … Import from File … Entities … Single File … Choose File … Import. Further instructions / details are given in this short video: Video Link : 2181

Sometimes you need to do something on a schedule. Axeda Platform is primarily focused on processing events as they happen. But in the case where some action needs to take place periodically, there are Rule Timers. A Rule Timer has a schedule to run, and a list of rules its associated with. Rule Timer Schedules A schedule is defined by a string using the cron syntax. This syntax is extremely flexible and powerful, but can be hard to understand. The fields are as follows: Seconds (0-59) Minutes (0-59) Hours (0-23) Day-of-Month (1-31) Month (1-12) OR jan,feb,mar, apr ... Day-of-Week (0-7) (Sunday is 0 or 7) OR sun, mon, tue, wed, thu, fri, sat Year (optional field) Some examples "0 0 12 ? * WED" - which means "every Wednesday at 12:00 pm" "0 0/5 * * * ?" - means Fire every 5 minutes "0 0 2 * * ?" - means Fire at 2am every day Note: Rule Timer schedules are in GMT/UTC. Associated Expression Rules The Rule timer has no other purpose but to run Expression Rules. These rules can be System or Asset. SystemTimer means an Expression Rule with type set to SystemTimer. This rule will be run once per scheduled time. A system timer can run a script to export data every day, or enable some rules at the end of a beta program. The other type is an Expression Rule with type AssetTimer. This rule will be run for all associated assets at the scheduled time. Say you want to save the max speed every day for a fleet of vehicles. You have an Expression Rule that's associated with the model Vehicle. The rule  A Rule Timer is set to run every day. Rule SetMax Type Data If: Speed > MaxSpeed Then: SetDataItem("MaxSpeed", Speed) Rule DailyMax Type AssetTimer If MaxSpeed > 0 Then: SetDataItem("DailyMax", MaxSpeed) && SetDataItem("MaxSpeed", 0) Associated to Vehicles RuleTimer NightlyUpdate Schedule "0 0 9 * * * ?" Associated rule: DailyMax The SetMax rule stores the max speed in a dataitem for each Vehicle asset. The NightlyUpdate timer runs at 9am UTC (which is 3am Eastern US, and midnight PST.) It writes the max into a DailyMax dataitem and clears the MaxSpeed to get ready for another day. The effect of the timer is that each Vehicle asset will process an event and run any rules that apply to it. Note! If you create the MaxSpeed dataitem through the model wizard, it doesn't have an initial value! So the rule IF Speed > MaxSpeed will not do the comparison until the first day when the timer sets its value to be 0.

Mapping previous versions of ThingWorx Analytics API to ThingWorx Analytics 8.1 Services Since ThingWorx Analytics 8.1, the classic server monolith has been replaced by a series of independent microservices. This new structure groups services around specific elements of functionality (data, training, results). Thus the use of the previous API commands to access ThingWorx Analytics functions has been replaced by the use of ThingWorx Services. Those Services exist within specific Microservice Things accessible in the ThingWorx Platform 8.1. The table below shows a mapping of the most common previous API commands from version 8.0 and previous versions to the version 8.1 related services. The table below does not contain an exhaustive listing either of API commands nor of Services. The API commands used below are samples which might require further information like headers and Body once used. These are used in the table below for reference purposes.
