RxLogs Advanced Logging

PLog and DataLog (Loggers)

A file based advanced logging framework written in Kotlin.

Overview

PLogs provides quick & simple file logging solution. All logs are saved to files in storage path provided. These logs are helpful when developer wants to analyze user activities within the app. A new log file is created every hour on a user event. These logs can be filtered and sorted easily. Logs can easily be exported as zip file base on filter type. This zip file can be uploaded to server on export. PLogs also provide functionality to arrange data logs into a predefined directory structure. These logs can be used for a specific events within the app. Logs can be saved as encrypted data.

Setup

Add module to your project:

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

    allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

    dependencies {
    implementation 'com.github.umair13adil:RxLogs:[Latest_Version]'
    }

Usage

Add following implementation in your Application class.

class MainApplication : Application() {
    
        override fun onCreate() {
            super.onCreate()
    
            setUpPLogger() //Initialize PLogger here
        }

private fun setUpPLogger() {
             val logsPath = "PLogs"
             
                     val logsConfig = LogsConfig(
                             isDebuggable = true,
                             savePath = logsPath,
                             zipFileName = "MyLogs",
                             exportPath = logsPath + File.separator + "PLogsOutput"
                     )

                     PLog.applyConfigurations(logsConfig, saveToFile = true, context = context) //Initialize configurations
                   
         }
}

Where are my logs stored?


Your logs can be found in the path of your app's directory in storage:

--> Android/data/[YOUR_APP_PACKAGE]/files/[YOUR_LOGS_FOLDER_NAME]/Logs/

To Log data to file simply call like this


1. Simple Info Log

    PLog.logThis(TAG, "method_name", "Log: " + Math.random(), LogLevel.INFO)

2. Simple Warning Log

    PLog.logThis(TAG, "method_name", "This is a warning message!", LogLevel.WARNING)

3. Error Log

    PLog.logThis(TAG, "method_name", "This is a error message!", LogLevel.ERROR)

4. Severe Log

    PLog.logThis(TAG, "method_name", "This is a severe error message!", LogLevel.SEVERE)

5. Exception Log

    PLog.logThis(TAG, "reportError", Exception("This is an Exception!"))

6. Throwable Log

    PLog.logThis(TAG, "reportError", Throwable("This is an Throwable!"))

7. Exception Log with Info

    PLog.logThis(TAG, "reportError", info = "Some Info", exception = Exception("This is an Exception!"), level =  LogLevel.ERROR)

8. Throwable Log with Info

    PLog.logThis(TAG, "reportError", info = "Some Info", throwable = Throwable("This is an Exception!"), level =  LogLevel.SEVERE)

ELK Elastic Stack Support


To configure set this flag to true:

    PLogMetaInfoProvider.elkStackSupported = true

Send additional Meta info for better filtering at LogStash dashboard. This has to be set once on application start.

    PLogMetaInfoProvider.setMetaInfo(MetaInfo(
                /**App**/
                appId = BuildConfig.APPLICATION_ID,
                appName = getString(R.string.app_name),
                appVersion = BuildConfig.VERSION_NAME,
                language = "en-US",

                /**Environment**/
                environmentId = BuildConfig.APPLICATION_ID,
                environmentName = BuildConfig.BUILD_TYPE,

                /**Organization**/
                organizationId = "9975",
                organizationUnitId = "24",
                organizationName = "BlackBox",

                /**User**/
                userId = "12112",
                userName = "Umair",
                userEmail = "m.umair.adil@gmail.com",
                deviceId = "12",

                /**Device**/
                deviceSerial = "SK-78",
                deviceBrand = Build.BRAND,
                deviceName = Build.DEVICE,
                deviceManufacturer = Build.MANUFACTURER,
                deviceModel = Build.MODEL,
                deviceSdkInt = Build.VERSION.SDK_INT.toString(),
                batteryPercent = "87",

                /**Location**/
                latitude = 0.0,
                longitude = 0.0,

                /**Labels**/
                labels = hashMapOf(Pair("env", "dev"))
        ))

Enable MQTT Feature


Note: PLogger currently supports SSL connection for MQTT.

Step 1:

Add certificate in your app's raw resource directory.

Step 2:

Add following block for initializing MQTT logging.

        PLogMQTTProvider.initMQTTClient(applicationContext,
                topic = "YOUR_TOPIC",
                brokerUrl = "YOUR_URL", //Without Scheme
                certificateRes = R.raw.m2mqtt_ca,
                clientId = "5aa39cef4d544d658ecaf23db701099c",
                writeLogsToLocalStorage = true,
                initialDelaySecondsForPublishing = 30,
                debug = true
        )

That's it, MQTT setup is done.
