Mobile Platform as a Service:Add performance log

Supports log tracking based on the mPaaS framework and native projects.

Based on the mPaaS framework

1. Lag monitoring is enabled for 10% devices by default. You can set the percentage through the following API:

    [MPAnalysisHelper setLagMonitorPercent: 100]; // Lag monitoring is enabled for all devices. The percentage needs to be set before the startPerformanceMonitor API is called.

   Lag monitoring is enabled only on a real device not in the Xcode debug state.

2. You need to call [MPAnalysisHelper startPerformanceMonitor] during App startup. It is recommended that this API be called in the-(void)application:(UIApplication *)application beforeDidFinishLaunchingWithOptions:(NSDictionary *)launchOptions launchOptions method.

   

Based on a native project

A performance monitoring API is encapsulated in the SDK. We recommend that you call the [PerformanceHelper performanceMonitor] API in the - (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions method of AppDelegate.

#import "PerformanceHelper.h"
    #import <MPAnalysis/MPAnalysisHelper.h>

    static NSTimeInterval __start_timestamp = 0;

    @implementation PerformanceHelper

    + (void)load
    {
        __start_timestamp = CFAbsoluteTimeGetCurrent();
    }

    + (void)performanceMonitor
    {
        //start performance monitor

       [MPAnalysisHelper setLagMonitorPercent: 100]; // Lag monitoring is enabled for all devices. The percentage needs to be set before the startPerformanceMonitor API is called.
        [MPAnalysisHelper startPerformanceMonitor];

        //record the time interval used for the app startup
        NSTimeInterval time = CFAbsoluteTimeGetCurrent() - __start_timestamp;
        [[MPAnalysisHelper sharedInstance] writeLogForStartupWithTime:time];

    }

    @end

Customize performance monitoring thresholds

When the default performance monitoring thresholds cannot meet your needs, you can customize relevant thresholds.

Set lag threshold

#Introduce header files
#import <MPMasAdapter/MPAnalysisHelper.h>

/**
 Set the threshold for main thread lag monitoring, in seconds, optional. The default value is 2 seconds.
 */
+ (void)setLagTimeThreshold:(NSUInteger)threshold;

/**
 Set the interval between lag detection. It is recommended that lagTimeThreshold / lagCheckInterval be equal to an integer
 */
+ (void)setLagCheckInterval:(NSTimeInterval)interval;

Set stuck threshold

#import <MPMasAdapter/MPMasSettings.h>

#Create the MPMasSettings category and rewrite the following method to customize it


/**
 Get the stuck duration threshold. If it needs to be customized, rewrite it in Category. It is recommended that anrTimeThreshold / anrCheckInterval be equal to an integer.
 */
- (NSUInteger)anrTimeThreshold
{
    return customized duration;
}


/**
 Get the stuck detection interval. If it needs to be customized, rewrite it in Category. It is recommended that anrTimeThreshold / anrCheckInterval be equal to an integer.
 */
- (NSTimeInterval)anrCheckInterval
{
    return customized detection interval length;
}

Set the startup stuck time threshold

#import <MPMasAdapter/MPMasSettings.h>

#Create the MPMasSettings category and rewrite the following method to customize it


/**
 Get the startup stuck time threshold. If it needs to be customized, rewrite it in Category.
 */
- (NSUInteger)startupAnrTimeThreshold
{
    return customized duration;
}
