Strace

print global id in application log file, now only support log4j2

how to use

1. libraryDependencies in build.sbt

   io.github.wtog.strace %% strace % 1.0.0-SNAPSHOT

2. log4j2.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <configuration monitorInterval="30" status="warn" packages="org.apache.logging.log4j.core">
   <Appenders>
       <Console name="STDOUT" target="SYSTEM_OUT">
           <PatternLayout pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} [%level] %logger %thread %G - %message%n%xException"/>
       </Console>
   </Appenders>
   
   <Loggers>
       <Root level="INFO" additivity="false">
           <appender-ref ref="STDOUT"/>
       </Root>
   </Loggers>
   </configuration>

   %G in PatternLayout is used to print global id

3. set Future Execute Context by

   import io.github.wtog.strace.TraceExecuteContext._

4. use akka to build custom execution context

   akka {
       actor {
           default-dispatcher = {
               type = "io.github.wtog.strace.extend.akka.TracePropagatingDispatcherConfigurator"
           }
           cpu-dispatcher = {
               type = "io.github.wtog.strace.extend.akka.TracePropagatingDispatcherConfigurator"
               executor = "fork-join-executor"
               fork-join-executor {
                   parallelism-min = 8
                   parallelism-factor = 3.0
                   parallelism-max = 64
               }
               throughput = 5
           }
           io-dispatcher = {
               type = "io.github.wtog.strace.extend.akka.TracePropagatingDispatcherConfigurator"
               executor = "thread-pool-executor"
               thread-pool-executor {
                   fixed-pool-size = 32
               }
               throughput = 1
           }
       }
   }
