IoT Monitoring provides you with three dashboards below to view and analyze the performance and usage of your application. Each dashboard provides you with a different aspect of your application's performance. Within each dashboard, you can view data visualized as widgets or detailed records or create custom widgets based on your chosen parameters. 

The page introduces the features, functionality, and goal of each of the following dashboards: 

  • Devices
  • Network Requests
  • Errors

Device Dashboard

The Device Dashboard enables you to monitor your device status, custom information, device status, and custom device application information. You can view summary activity or use filters to drill down to view metrics for a specific device.

Using the Device Dashboard, DevOps can ensure that devices are up and running, product managers and business stakeholders can examine device activity and trends, and developers can drill down into results to identify issues affecting single or multiple devices.

Network Requests Dashboard

The Network Requests Dashboard enables you to view outgoing network requests, network request details, and analyze network requests. 

With the Network Requests Dashboard, you can do the following:

  • Check the availability of a device or service

  • Discover slow network requests

  • View failed network requests

  • Analyze and sort network requests by criteria such as status code, app version, etc.

  • Monitor network traffic over time

Errors

The Errors Dashboard enables you to view crashes, exceptions, and custom errors, both fatal and non-fatal. DevOps can monitor activity list and notify developers of error events. The developers can select the error event to view details and download the stack trace for debugging.


The stack trace will only be available if it is reported with the IoT SDKs or through the IoT REST API.

With the Errors Dashboard, you can do the following:

  • Discover new errors

  • Assess the scope and impact of errors, such as how many devices are affected, what type of devices are affected, and how seriously affected are the devices.

  • Monitor error patterns

  • Download stack traces of errors to debug code

  • Discover broken devices (failed hardware)

How to Use IoT Dashboards

Although each dashboard presents different information, they all have the same UI functionality and features. This page provides an overview of the dashboard functionality to help you get started monitoring your devices.

Access the IoT Dashboards

  1. Open the application in which you are interested.
  2. Select one of the dashboards to view: 
    • Devices
    • Network Requests
    • Errors

View Dashboard Summaries

From each dashboard, you can view aggregated data in predefined and custom widgets. Each dashboard is in view mode by default, so data is read-only, although you can set filters, view details, and resize widgets.

View Details

To view details, you select a row in one of the tables and click the Details icon. This will bring up the Device Details dialog seen below. Here you can view when the three types of events (Custom Event, Network Request, and Error) occurred on the timeline or by duration. You can also click on the event bar in the waterfall for more details. 

Filter Results 

You can filter results by adding criteria. This enables you to focus on factors affecting availability, usage, and performance. 

In the screenshot below, the criteria operatingsystemversion is added, which could potentially home in on performance issues caused by a particular operating system version.

Modify Content and Presentation

To modify the dashboard, you need to be in Edit mode. You simply change the toggle to Edit, and then you'll be able to add, move, resize, remove, and even create widgets.

Build Custom Dashboard Widgets

Each dashboard has predefined widgets for basic monitoring, but because there are so many different devices and platforms, you will need to create custom widgets with the Widget Builder, which guides you through the creation of a widget. This page provides guidance for selecting graph types and using filters when you create widgets.

How to Access the Widget Builder 

  1. Select a dashboard.
  2. Change to Edit mode.
  3. From the toolbar, click Add Widget.
  4. From the dropdown, click Create a Widget.

Choose the Best Graph Type

The Widget Builder allows you to choose from one of six types of graphs, you should try to use the best graph for your data set. The following is a guideline for choosing the graph type: 

Graph TypeGraph PropertiesUse Case(s)Example Graph
Pie Chart
  • Field
  • Subfield
  • Filters
  • Name

Use pie charts to compare parts of a whole.

Examples:

  • For a retail device, the percentage of sales for each store.
  • For a fitness device, the percentage of different types of activities such as running, bicycling, walking.
Bar Chart
  • Field
  • Subfield
  • Filters
  • Name

Use bar charts to compare different items within the same category.

Examples:

  • For an inventory device, the number of items per store.
  • For a smart car, the mileage of different cars.
Time Series
  • Field
  • Filters
  • Name

Use a time series to measure events over time. 

Examples:

  • network errors
  • sales
Histogram
  • Field
  • Filters
  • Name

Use histograms to analyze and understand the distribution of large sets of numerical data.

Examples:

  • The distribution of network request duration.
  • For a smart home device, the distribution of temperatures.
Number
  • Field
  • Filters
  • Name

Use a number graph to highlight an important data point.

Examples:

  • active devices
  • sales total
  • network errors
Table
  • Field
  • Filters
  • Name

Use a table to view detailed data for a list of similar items.

Examples:

  • customers
  • network requests
  • devices

How to Use Filters

Filters enable you to narrow your results to meaningful information. For example, suppose you wanted to see the total number of items sold at each store, but you were particularly interested in those more expensive items. You could choose a bar graph and use the field Device Name and the subfield TransactionAmount with the filter price > 50 to view the transactions of the devices that with an average cost greater than $50 as shown in the example widget below.
