On the devices are deployed **two functions - one for monitoring machine temperature and another one for ambient humidity**. The functions monitor if the values are above predefined threshold and if so, send the data to a **IoT Hub**. In the IoT Hub the data is filtered and it is sent to one of the configured **Event Hubs** to persist in **Time Series Insights** or pass it for aggregation by **Azure Stream Analytics**. If there are more events than predefined threshold in **Azure Stream Analytics** an **Azure Function** is triggered to send an email to the responsible technician. 12 | 13 | A walkthrough for building the project is provided below. 14 | 15 | ## Walkthrough 16 | 17 | ### 1. Setting Up Edge Devices 18 | 19 | Finding and using a real IoT device is sometimes difficult so we will use Azure VM instead. 20 | 21 | Please follow the instructions in this tutorial to [deploy Azure IoT Edge runtime on Azure Linux VM](https://docs.microsoft.com/en-us/azure/iot-edge/tutorial-simulate-device-linux "deploy Azure IoT Edge runtime on Azure Linux VM"). 22 | 23 | ### 2. Azure Function on IoT Edge 24 | 25 | Next, we will deploy our first Azure Function that will be responsible for monitoring machines temperature. For that step follow the tutorial for [deploying Azure Function to IoT Edge](https://docs.microsoft.com/en-us/azure/iot-edge/tutorial-deploy-function "deploying Azure Function to IoT Edge"). You can find all required assets for this function in the folder [Temperature Filter Function](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/tree/master/AzureIoTEdgeFunctions/TemperatureFilterFunction "Temperature Filter Function") 26 | 27 | Source Code for functions: 28 | 29 | ```csharp 30 | 31 | #r "Microsoft.Azure.Devices.Client" 32 | #r "Newtonsoft.Json" 33 | 34 | using System.IO; 35 | using Microsoft.Azure.Devices.Client; 36 | using Newtonsoft.Json; 37 | 38 | public static async Task Run(Message messageReceived, IAsyncCollector output, TraceWriter log) 39 | { 40 | // Temperature Threshold 41 | const int temperatureThreshold = 25; 42 | byte[] messageBytes = messageReceived.GetBytes(); 43 | var messageString = System.Text.Encoding.UTF8.GetString(messageBytes); 44 | 45 | if (!string.IsNullOrEmpty(messageString)) 46 | { 47 | // Get the body of the message and deserialize it 48 | var messageBody = JsonConvert.DeserializeObject(messageString); 49 | 50 | // Check temperature value 51 | if (messageBody != null && messageBody.machine.temperature > temperatureThreshold) 52 | { 53 | // We will send the message to the output as the temperature value is greater than the threashold 54 | var filteredMessage = new Message(messageBytes); 55 | // We need to copy the properties of the original message into the new Message object 56 | foreach (KeyValuePair prop in messageReceived.Properties) 57 | { 58 | filteredMessage.Properties.Add(prop.Key, prop.Value); 59 | } 60 | // We are adding a new property to the message to indicate it is a temperature alert 61 | filteredMessage.Properties.Add("MessageType", "Alert"); 62 | // Send the message 63 | await output.AddAsync(filteredMessage); 64 | log.Info("Received and transferred a message with temperature above the threshold"); 65 | } 66 | } 67 | } 68 | 69 | ``` 70 | The second function will monitor ambient humidity. You can follow the same tutorial for [deploying Azure Function to IoT Edge](https://docs.microsoft.com/en-us/azure/iot-edge/tutorial-deploy-function "deploying Azure Function to IoT Edge") with a few modifications: 71 | 72 | * In **Create a function project** change the function code to below. You can find all required assets for this function in the folder [Humidity Filter Function](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/tree/master/AzureIoTEdgeFunctions/HumidityFilterFunction "Humidity Filter Function"): 73 | 74 | ```csharp 75 | ... 76 | 77 | public static async Task Run(Message messageReceived, IAsyncCollector output, TraceWriter log) 78 | { 79 | // Threshold for Humidity 80 | const int humidityThreshold = 24; 81 | 82 | byte[] messageBytes = messageReceived.GetBytes(); 83 | var messageString = System.Text.Encoding.UTF8.GetString(messageBytes); 84 | 85 | if (!string.IsNullOrEmpty(messageString)) 86 | { 87 | ... 88 | 89 | // Check for humidity value 90 | if (messageBody != null && messageBody.ambient.humidity > humidityThreshold) 91 | { 92 | ... 93 | 94 | filteredMessage.Properties.Add("MessageType", "HumidityAlert"); 95 | // Send the message 96 | await output.AddAsync(filteredMessage); 97 | log.Info("Received and transferred a message with ambient humidity above the threshold"); 98 | } 99 | } 100 | } 101 | 102 | ``` 103 | 104 | 105 | * Modify the IoT Hub routes to the following configuration: 106 | 107 | ```json 108 | { 109 | "routes": { 110 | "sensorToFilter": "FROM /messages/modules/tempSensor/outputs/temperatureOutput INTO BrokeredEndpoint(\"/modules/temperatureFilter/inputs/input1\")", 111 | "sensorToHumidityFilter": "FROM /messages/modules/tempSensor/outputs/temperatureOutput INTO BrokeredEndpoint(\"/modules/humidityFilter/inputs/input1\")", 112 | "filterToIoTHub": "FROM /messages/modules/temperatureFilter/outputs/* INTO $upstream", 113 | "humidityFilterToIoTHub": "FROM /messages/modules/humidityFilter/outputs/* INTO $upstream" 114 | } 115 | } 116 | ``` 117 | 118 | ### 3. Configure IoT Hub 119 | 120 | Next, the connections to the 3 Event Hub instances need to be configured. These Event Hub instances will be responsible for getting the data from IoT Hub and passing it along for further processing. 121 | 122 | IoT Hub Endpoints will be defined for each of the Event Hubs as shown below: 123 | 124 | ![IoT Hub Endpoints](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/IotHubEndpoints.PNG "IoT Hub Endpoints") 125 | 126 | Next, the rules for routing data to the correct IoT Hub instance are defined. The final configuration looks like: 127 | 128 | ![IoT Hub Routes](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/IotHubRoutes.PNG "IoT Hub Routes") 129 | 130 | Next configure the humidity route: 131 | 132 | ![IoT Hub Humidity Route](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/IotHubHumidityRoute.PNG "IoT Hub Humidity Route") 133 | 134 | Two of the Event Hubs are connected to Stream Analytics Jobs that are aggregating the values and based on a predefined threshold trigger built using an Azure Function for sending an email. 135 | 136 | Below is the Azure Stream Analytics job for humidity: 137 | 138 | ```sql 139 | SELECT 140 | System.TimeStamp AS Time, 141 | COUNT(*) AS [Count] 142 | INTO 143 | humidityout 144 | FROM 145 | humidity TIMESTAMP BY TIMECREATED 146 | GROUP BY 147 | TumblingWindow(second, 180) 148 | HAVING 149 | [Count] >= 5 150 | ``` 151 | 152 | Below is the Azure Stream Analytics job for temperature: 153 | 154 | ```sql 155 | SELECT 156 | System.TimeStamp AS Time, 157 | COUNT(*) AS [Count] 158 | INTO 159 | AlertOutput 160 | FROM 161 | temperature TIMESTAMP BY TIMECREATED 162 | GROUP BY 163 | TumblingWindow(second, 180) 164 | HAVING 165 | [Count] >= 5 166 | ``` 167 | 168 | ### 4. Azure Functions for Alerting 169 | 170 | An email will be sent when there are: 171 | - More than 5 elevated temperature events within a 3 minute window. 172 | - More than 5 ambient humidity events within a 3 minute window. 173 | 174 | Azure Stream Analytics has first party integration with Azure Functions. Using Azure Function Runtime v2, follow these [steps](https://docs.microsoft.com/en-us/azure/azure-functions/functions-versions "Configure Azure Function App to use runtime version 2") to configure your Function App. The code for the function is below: 175 | 176 | ```csharp 177 | #r "Newtonsoft.Json" 178 | #r "SendGrid" 179 | 180 | using System.Net; 181 | using Microsoft.AspNetCore.Mvc; 182 | using Microsoft.Extensions.Primitives; 183 | using Newtonsoft.Json; 184 | using SendGrid.Helpers.Mail; 185 | using System.Text; 186 | 187 | public async static Task Run(HttpRequest req, IAsyncCollector messages, TraceWriter log) 188 | { 189 | log.Info("SendGrid message"); 190 | using (StreamReader reader = new StreamReader(req.Body, Encoding.UTF8)) 191 | { 192 | var body = await reader.ReadToEndAsync(); 193 | var message = new SendGridMessage(); 194 | message.AddTo("technicians@iot.com"); 195 | message.AddContent("text/html", body); 196 | message.SetFrom("iot@alert.com"); 197 | message.SetSubject("[Alert] IoT Hub Notrtification"); 198 | await messages.AddAsync(message); 199 | return (ActionResult)new OkObjectResult("The E-mail has been sent."); 200 | } 201 | } 202 | ``` 203 | 204 | Configure the function in function.json file: 205 | 206 | ```json 207 | { 208 | "bindings": [ 209 | { 210 | "authLevel": "function", 211 | "name": "req", 212 | "type": "httpTrigger", 213 | "direction": "in" 214 | }, 215 | { 216 | "name": "$return", 217 | "type": "http", 218 | "direction": "out" 219 | }, 220 | { 221 | "type": "sendGrid", 222 | "name": "messages", 223 | "apiKey": "SendGridAttribute.ApiKey", 224 | "direction": "out" 225 | } 226 | ], 227 | "disabled": false 228 | } 229 | ``` 230 | 231 | This function requires that you set a SendGrid key using the App Setting property called "SendGridAttribute.ApiKey" inside the Function App. In the Azure portal you can create free account for SendGrid with 20 000 email per month. 232 | 233 | All the assets for the email function can be found [here](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/tree/master/AzureFunctions/HttpHumidityAlertV2 "Folder for Azure Function responsible for sending emails") 234 | 235 | 236 | ### 5. Analyzing Data with Time Series Insights 237 | 238 | IoT Hub sends all recieved events to an instance of Event Hub. This Event Hub is configured to be a source of data for a [Time Series Insights](https://azure.microsoft.com/en-us/services/time-series-insights/) instance: 239 | 240 | ![Time Series Insights Data Source](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/TimeSeriesInsights-EventSources.PNG "Time Series Insights Data Source") 241 | 242 | Time Series Insights was built with IoT scenarios in mind. It combines familiar SQL syntax and powerful visualization capabilities in one product designed for massive data throughput. 243 | 244 | Time Series Insights automatically parses the data and shows a default graph for event count: 245 | 246 | ![Deafult dashboard for Time Series Insights](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/TimeSeriesInsights.png "Deafult dashboard for Time Series Insights") 247 | 248 | To configure multiple queries whose graphs can overlay: 249 | 250 | ![Mutiple queries in Time Series Insights](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/TimeSeriesInsights-Queries.PNG "Mutiple queries in Time Series Insights") 251 | 252 | This can be done by cloning a query and modifying it. But it is recommended to plot each query on separate part of dashboard for better visibility: 253 | 254 | ![Time Series Insights with mutiple queries displayed on a dashboard](https://github.com/Azure-Samples/Azure-Functions-IoT-TimeSeries-Analytics/blob/master/Images/Time%20Series%20Dashboard.PNG "Time Series Insights with mutiple queries displayed on a dashboard") 255 | 256 | **Congratulations! You have just built complete IoT solution including edge logic, IoT Hub, alerting email functions and detailed data view powered by Time Series Insights!** 257 | --------------------------------------------------------------------------------
