Steps to implement TelemetryApp in Windows Store apps using API:

 

1. Create Telemetry account (telemetryapp.com)
There are two types of telemetry accounts
Telemetry Enterprise Edition – It is a premium account offering by telemetry. For more information Enterprise Edition account page.
Telemetry Community Edition – It is a free account which has very limited features to provide a preview of telemetry for new organizations. For more information please see our Community Edition account page.

2. After Successful login in to the telemetryapp.com, initially you will be prompted to add a Board.

create board
Board:
A Board (dashboard) is a collection of widgets linked to metrics organized across a user determined layout. Below is an example screenshot how a board looks after adding widgets.

Agents:

After successful creation of board now we need an agent to communicate with the board.

– Go to Agents tab and select Add agent

Add Agent

– Give a name and click on create

Agent Name

– Copy the Agent token to secure place, you will not be able to see it again.

Widgets:

Boards contain widgets. A widget may be a chart, a number or simply a box to contain other widgets

Adding a widget to the board:

a. Select Add Widget option right above board properties

Add properties

b. Now select a widget which is suitable for your application.

c. After adding widget the board looks like below

Flows:

Flows are objects that represent the flow of metrics within Telemetry.

Adjusting Board Properties:

Here you can title your Board and adjust the settings, or properties, of your Board.

Widget Properties:

After adding Flows to your Board, you can select a Flow and edit the properties of the selected Flow.

view widget properties

Layers:

  • All your widgets on a board can be found as a list of layers under the Layers tab.

Boxes:

  • Each widget box can be moved around, resized, and even layered.
  • Select a widget you want to adjust, and on hover you can see options to drag out and resize your box or to move it.
  • You can even have just one or two very large widgets on a board.

Adding a Logo:

  • The best way to personalize and brand your board, is to add a custom logo to your board.
  • From our Image widget, upload an image of your logo directly to your board if you have a paid plan with us.
  • You can then change the background color of the Image widget so your logo looks its best.

Board Backgrounds:

  • Add an image or color background to give your board(s) a custom theme.
  • Adjust your widget background color and opacity so your widgets and background are visible.

Widget Background:

  • Adjust your widget background color and opacity so your widgets and background are visible.

Board Layout:

  • Do you want to create 5 tidy columns on your board but notice you have extra space or one column is smaller or larger than the others? You can adjust the number of rows and columns your widgets snap to under Board Properties.

4. Implement telemetry in Windows store or Phone app using API

In this article I am using bar chart to explain how to implement in windows store apps. The procedure is same for all widgets.
Bar Chart:

A bar chart is a stack of horizontal bars, each with a label, value and colour. The value determines the length of the bar. The bars will be sorted from top to bottom in terms of length by default. You can choose to turn off sorting. Send data with a hash of bars containing an array with each bar as a hash. Bar charts can display a maximum of 20 bars. There may be less than 20 shown if your widget box is too small. Resize your widget box if all your data is not being displayed.

Parameters

Parameter

Notes

Type

Description

bars

Required

array of objects

The bars

bars[]color

Required

CSS color

The color of the bar.

bars[]label

Required

string

The text to overlay on top of the bar.

bars[]value

Required

number

A number representing the value of the barchart. This will determine the length of the bar.

max

 

integer

The min possible value of the bar.

min

 

integer

The max possible value of the bar.

sort

 

boolean

Whether to sort the bars by value or not. The default is true.

– Adding a Bar Chart into board.
Log in into telemetryapp.com, go to boards and select edit board.

edit board

– Now click on add widget, under charts select Bar Chart.

add widget bar chart

select bar chart

After adding Bar chart into board, select the bar chart on board, now go to widget tab in properties window and expand general tab.

bar chart properties

Copy the Flow Tag to a note pad.

bar chart flow tag name

Now we have a widget to display the flow data on board.

5. Create a Windows store or Phone app (Phone 8.1 or Windows 8.1) project in visual studio to send flows to bar chart from windows app, in my example I created a Universal Hub App project.

create windows store app

Open HubPage.xaml.cs, under load state method write the following code to send the flow data to recently created Bar Chart.

To use API we need the following information

  • URI
  • API Token (refer step 2 under Agents)
  • Flow Tag (In earlier step we copied flow tag for bar chart)

URI = “https://api.telemetryapp.com/flows/Flow Tag/”;

For Authentication/Authorization we need to pass Agent Token as user name and password as blank in POST method.

Prepare list of bars information:

In this example I am using bar chart 

public class Bar
        {
            public string color { get; set; }
            public string label { get; set; }
            public int value { get; set; }
        }

        public class BarRootObject
        {
            public List<Bar> bars { get; set; }
        }

 

BarRootObject barRootObject = new BarRootObject();
            barRootObject.bars = new List<Bar>();
            var bar = new Bar();
            bar.color = "#66CC00";
            bar.label = "Users";
            bar.value = 4;
            barRootObject.bars.Add(bar);

            bar = new Bar();
            bar.color = "#FF8900";
            bar.label = "Sessions";
            bar.value = 30;
            barRootObject.bars.Add(bar);

            bar = new Bar();
            bar.color = "#FFFF33";
            bar.label = "Crashes";
            bar.value = 26;
            barRootObject.bars.Add(bar);

            bar = new Bar();
            bar.color = "#FF0000";
            bar.label = "Exceptions";
            bar.value = 75;
            barRootObject.bars.Add(bar);

In above code I am passing four bars information which include colour, label and value (If you want to know/pass more properties info please refer Bar charts Flow Object table above).

POST Method:

string URI = "https://api.telemetryapp.com/flows/testtelemetry_piechart_1/&quot;;
            HttpClient httpClient = new HttpClient();
            httpClient.DefaultRequestHeaders.Authorization = CreateBasicHeader("**Replce with Agent Token**", "");
            metrics metric= new metrics();
            metric.values =new int[]{10,70,25,5};
            metric.labels = new string[] { "A", "B", "C", "D" };
            metric.colors = new string[] { "#1F1F33", "#669900", "#7A0000", "#334C4C" };
            string postData = JsonConvert.SerializeObject(metric);
            StringContent c = new StringContent(postData, Encoding.UTF8, "application/json");
            httpClient.MaxResponseContentBufferSize = 100000;
            var result = await httpClient.PostAsync(URI, c);
            var content = await result.Content.ReadAsStringAsync();

 

Method for creating Authentication Header Value:

public static AuthenticationHeaderValue CreateBasicHeader(string username, string password)
        {
            byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(username + ":" + password);
            return new AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
        }

6. Run the App

Now go to telemetry dashboard and check the bar chart has added four new bars with values.
