This is the repository of the iOS SDK for Application Insights. Application Insights is a service that monitors the performance and usage of your published app. The SDK enables you to send telemetry of various kinds (events, traces, sessions etc.) to the Application Insights service where your data can be visualized in the Azure Portal.
You can use the Application Insights for Mac tool to integrate the Application Insights iOS SDK into your existing apps. The SDK runs on devices with iOS 6.0 or higher. You'll need a subscription to Microsoft Azure. (It's free until you want to send quite a lot of telemetry.)
Version 1.0-beta.8 of the Application Insights for iOS SDK comes with two major changes:
Crash Reporting and the API to send handled exceptions have been removed from the SDK. In addition, the Application Insights for iOS SDK is now deprecated.
The reason for this is that HockeyApp is now our major offering for mobile and cross-plattform crash reporting, beta distribution and user feedback. We are focusing all our efforts on enhancing the HockeySDK and adding telemetry features to make HockeyApp the best platform to build awesome apps. We've launched HockeyApp Preseason so you can try all the new bits yourself, including User Metrics.
We apologize for any inconvenience and please feel free to contact us at any time.
NSTimeInterval parameter with the duration in seconds.See here for the release notes of previous versions.
The SDK runs on devices with iOS 6.0 or higher.
We recommend integration of our binary into your Xcode project to setup Application Insights for your iOS app. For other ways to setup the SDK, see Advanced Setup.
You can use the Application Insights for Mac tool to integrate the SDK, which provides you with a step-by-step wizard for this process. If you want to integrate the SDK manually, you can do that by following this steps:
To view your telemetry, you'll need an Application Insights resource in the Microsoft Azure Portal. You can either:
Open your resource and open the Essentials drop-down. Shortly, you'll need to copy the Instrumentation Key.
ApplicationInsights .From our experience, 3rd-party libraries usually reside inside a subdirectory (let's call our subdirectory Vendor), so if you don't have your project organized with a subdirectory for libraries, now would be a great start for it. To continue our example, create a folder called "Vendor" inside your project directory and move the unzipped ApplicationInsights-folder into it.
Vendor.Project Navigator is visible (⌘+1)ApplicationInsights.framework from your window in the Finder into your project in Xcode and move it to the desired location in the Project Navigator (e.g. into the group called Vendor)Create groups for any added folders and set the checkmark for your target. Then click Finish.Info.plist of your app target and add a new field of type String. Name it MSAIInstrumentationKey and set your Application Insights instrumentation key from 4.1 as its value.Objective-C
AppDelegate.m file.Add the following line at the top of the file below your own import statements:
@import ApplicationInsights;Search for the method application:didFinishLaunchingWithOptions:
Add the following lines to setup and start the Application Insights SDK:
[[MSAIApplicationInsights sharedInstance] setup];
// Do some additional configuration if needed here
//... more of your other setup code here ...
[[MSAIApplicationInsights sharedInstance] start];You can also use the following shortcuts:
[MSAIApplicationInsights setup];
[MSAIApplicationInsights start];Swift
AppDelegate.swift file.Add the following line at the top of the file below your own import statements:
import ApplicationInsightsSearch for the method
application(application: UIApplication, didFinishLaunchingWithOptions launchOptions:[NSObject: AnyObject]?) -> Bool`Add the following lines to setup and start the Application Insights SDK:
MSAIApplicationInsights.sharedInstance().setup();
MSAIApplicationInsights.sharedInstance().start();You can also use the following shortcuts:
MSAIApplicationInsights.setup()
MSAIApplicationInsights.start()Congratulation, now you're all set to use Application Insights! See Basic Usage on how to use Application Insights.
It is also possible to set the instrumentation key of your app in code. This will override the one you might have set in your Info.plist. To set it in code, MSAIApplicationInsights provides an overloaded constructor:
[MSAIApplicationInsights setupWithInstrumentationKey:@"{YOUR-INSTRUMENTATIONKEY}"];
//Do additional configuration
[MSAIApplicationInsights start];If you are working with an older project which doesn't support clang modules yet or you for some reason turned off the Enable Modules (C and Objective-C and Link Frameworks Automatically options in Xcode, you have to manually link some system frameworks:
Project Navigator (⌘+1).Build Phases.Link Binary With Libraries.CoreTelephonyFoundationSecuritySystemConfigurationUIKitlibzNote that this also means that you can't use the @import syntax mentioned in the Modify Code section but have to stick to the old #import <ApplicationInsights/ApplicationInsights.h>.
The following points need to be considered to use the Application Insights SDK with iOS 8 Extensions:
CFBundleShortVersionString) and build number (CFBundleVersion) as the main app uses. (This is required only if you are using the same MSAIInstrumentationKey for your app and extensions).applicationDidFinishLaunching: equivalent and viewDidLoad can run multiple times, you need to use a setup like the following example:@interface TodayViewController () <NCWidgetProviding>
@property (nonatomic, assign) BOOL didSetupApplicationInsightsSDK;
@end
@implementation TodayViewController
- (void)viewDidLoad {
[super viewDidLoad];
if (!self.didSetupApplicationInsightsSDK) {
[MSAIApplicationInsights setup];
[MSAIApplicationInsights start];
self.didSetupApplicationInsightsSDK = YES;
}
}WatchKit extensions don't use regular UIViewControllers but rather WKInterfaceController subclasses. These have a different lifecycle than you might be used to.
To make sure that the Application Insights SDK is only instantiated once in the WatchKit extension's lifecycle we recommend using a helper class similar to this:
@import Foundation;
@interface MSAIWatchSDKSetup : NSObject
+ (void)setupApplicationInsightsIfNeeded;
@end#import "MSAIWatchSDKSetup.h"
#import "ApplicationInsights.h"
static BOOL applicationInsightsIsSetup = NO;
@implementation MSAIWatchSDKSetup
+ (void)setupApplicationInsightsIfNeeded {
if (!applicationInsightsIsSetup) {
[MSAIApplicationInsights setup];
[MSAIApplicationInsights start];
applicationInsightsIsSetup = YES;
}
}
@endThen, in each of your WKInterfaceControllers where you want to use the Application Insights SDK, you should do this:
#import "InterfaceController.h"
#import "ApplicationInsights.h"
#import "MSAIWatchSDKSetup.h"
@implementation InterfaceController
- (void)awakeWithContext:(id)context {
[super awakeWithContext:context];
[MSAIWatchSDKSetup setupApplicationInsightsIfNeeded];
}
- (void)willActivate {
[super willActivate];
}
- (void)didDeactivate {
[super didDeactivate];
}
@endThe developer mode is enabled automatically in case the debugger is attached or if the app is running in the simulator. This will decrease the number of telemetry items sent in a batch (5 items) as well as the interval items when telemetry will be sent (3 seconds).
We're all big fans of a clean debugging output without 3rd-party-SDKs messages piling up in the debugging view, right?! That's why Application Insights keeps log messages to a minimum (like critical errors) unless the developer specifically enables debug logging before starting the SDK:
[MSAIApplicationInsights setup]; //setup the SDK
[[MSAIApplicationInsights sharedInstance] setDebugLogEnabled:YES]; //enable debug logging
[MSAIApplicationInsights start]; //start using the SDKThis setting is ignored if the app is running in an app store environment, so the user's console won't be littered with our log messages.
[NOTE] The SDK is optimized to defer everything possible to a later time while making sure each module executes other code with a delay of some seconds. This ensures that applicationDidFinishLaunching: will process as fast as possible and the SDK will not block the startup sequence resulting in a possible kill by the watchdog process.
After you have set up the SDK as described above, the MSAITelemetryManager-instance is the central interface to track events, traces, metrics, page views or handled exceptions.
For an overview of how to use the API and view the results in the Application Insights resource, see API Overview. The examples are in Java, but the principles are the same.
// Send an event with custom properties and measurements data
[MSAITelemetryManager trackEventWithName:@"Hello World event!"
properties:@{@"Test property 1":@"Some value",
@"Test property 2":@"Some other value"}
measurements:@{@"Test measurement 1":@(4.8),
@"Test measurement 2":@(15.16),
@"Test measurement 3":@(23.42)}];
// Send a message
[MSAITelemetryManager trackTraceWithMessage:@"Test message"];
// Manually send pageviews with a duration of 200 ms (note: this will also be done automatically)
[MSAITelemetryManager trackPageView:@"MyViewController"
duration:200
properties:@{@"Test measurement 1":@(4.8)}];
// Send custom metrics
[MSAITelemetryManager trackMetricWithName:@"Test metric" value:42.2];
// Send an event with custom properties and measuremnts data
MSAITelemetryManager.trackEventWithName("Hello World event!",
properties:["Test property 1":"Some value",
"Test property 2":"Some other value"],
measurements:["Test measurement 1":4.8,
"Test measurement 2":15.16,
"Test measurement 3":23.42])
// Send a message
MSAITelemetryManager.trackTraceWithMessage("Test message")
// Manually send pageviews (duration 200 ms)
MSAITelemetryManager.trackPageView("MyViewController",
duration:0.2,
properties:["Test measurement 1":4.8])
// Send a message
MSAITelemetryManager.trackMetricWithName("Test metric", value:42.2)In the Azure portal, open the application resource that you created to get your instrumentation key. You'll see charts showing counts of page views and sessions. To see more:
The SDK also allows for some more advanced usages.
It is also possible to set so-called "common properties" that will then be automatically attached to all telemetry data items.
[MSAITelemetryManager setCommonProperties:@{@"custom info":@"some value"}];MSAITelemetryManager.setCommonProperties(["custom info":"some value"])Use the properties to segment and filter metric charts and filter searches.
Automatic collection of lifecycle events is enabled by default. This means that Application Insights automatically tracks the appearance of a view controller and manages sessions for you.
The automatic tracking of viewcontroller appearance can be disabled between setup and start of the SDK.
[MSAIApplicationInsights setup]; //setup the SDK
[[MSAIApplicationInsights sharedInstance] setAutoPageViewTrackingDisabled:YES]; //disable the auto collection
[MSAIApplicationInsights start]; //start using the SDKBy default, the Application Insights for iOS SDK starts a new session when the containing app is restarted (this means a 'cold start', i.e. when the app has not already been in memory prior to being launched) or when it has been in the background for more than 20 seconds.
You can either change this timeframe:
[MSAIApplicationInsights setAppBackgroundTimeBeforeSessionExpires:60];Turn of automatic session management completely:
[MSAIApplicationInsights setAutoSessionManagementDisabled:YES];This then requires you to manage sessions manually:
[MSAIApplicationInsights renewSessionWithId:@"4815162342"];Normally, a random anonymous ID is automatically generated for every user of your app by the SDK. Alternatively you can set your own user ID or other user attributes, which will then be attached to all telemetry events:
[[MSAIApplicationInsights sharedInstance] setUserWithConfigurationBlock:^(MSAIUser *user) {
user.userId = @"your_user_id";
user.accountId = @"[email protected]";
}];You can also configure a different server endpoint for the SDK if needed using a full URL
[MSAIApplicationInsights setup]; //setup the SDK
[[MSAIApplicationInsights sharedInstance] setServerURL:@"https://YOURDOMAIN/path/subpath"];
[MSAIApplicationInsights start]; //start using the SDKOur documentation can be found on CocoaDocs.
