Use Huawei performance management service to configure the sampling rate on demand

Android Huawei is used in the application AppGallery Connect Performance management services provided , Used for monitoring Android App Performance data for , Including commissioning APM When , From the log , Performance management SDK in , There's a lot of CPUMemoryEvent Events . For those who have not integrated performance management services, please refer to file coordination Github Demo Try to access .

from logccat According to the reported events , The frequency of reporting is still very high , Worry that the frequency of acquisition is too high , Will occupy the mobile phone CPU Resources for , The equipment and application are stuck . So we are studying how to configure performance management SDK Sampling rate .

The following steps and related screenshots are used to configure the sampling rate of Huawei performance management .

1、 Official document description ：

First, check the Huawei documents , Documentation for configuring the sampling rate , Is in “ Add custom monitoring configuration ” Inside , It's hidden deep , Link address Click here to .

It mainly involves three parts , Set the session sampling rate 、 The front desk CPU Acquisition frequency 、 Memory acquisition frequency of the foreground .

2、 Configuration steps

1、 Configure the session sampling rate

First, let's introduce the conversation ： Every time a user uses APP When , It's a conversation . Like you Application startup or App Switch to the foreground to start , To exit the application or switch to the background , It's a conversation

The session sampling rate refers to the probability of a session collection , The default is 1%. The higher the sampling rate , It will improve the probability of restoring the device information and user interaction track when the problem occurs ,

The configuration is as follows ： Open the app's Manifest file , stay <application> The configuration inside the label is as follows data：

<meta-data
    android:name="sessions_sampling_percentage"
    android:value="1.0" />

The number represents the percentage .

2、 Configure the application in the foreground CPU Acquisition frequency

The meaning of the name is easy to understand , Configuration App At the front desk CPU Sampling rate .

Open the app's Manifest file , stay <application> The configuration inside the label is as follows data：

<meta-data
    android:name="collect_cpu_frequency_fg_ms"
    android:value="100" />

The numerical unit is ms, The configuration above is 100ms, each 100ms Take a sample .

3、 Configure the memory acquisition frequency of the application in the foreground

Configuration App Backstage CPU Sampling rate , Generally, the configuration is a little lower , Prevent occupation CPU resources .

<meta-data
    android:name="collect_memory_frequency_fg_ms"
    android:value="200" />

The unit of numbers is also ms, For example, I wrote above , It's every 200ms Take a sample .
