MMTE Client Logs

LOGBack configuration for MMTE Client is specified by the Dlogback.configurationFile MMC vmarg system variable. Its default value is MetaMiner.logback.xml

By default, the most of MMTE Client logs are stored in <METAMINER CLIENT DATA DIRECTORY>\logs, but you can define alternative locations by changing MetaMiner.logback.xml.

Under Windows OS, <METAMINER CLIENT DATA DIRECTORY> usually resolves to something like C:\Users\<MyUserName>\AppData\Roaming\MetaMiner.

MMC Main Log

This is the main MMTE Client log. You can diagnose all critical activities on MMC by reading it.
Appender FILE
Config MetaMiner.logback.xml
Default Output file
Default Filename client.log
Default Level DEBUG for MetaMiner modules, WARN for others
Default Rotation/Retention max 5MB, max 5 volumes
Default Encoder (format) %date{dd.MM;HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg%n

Example:

02.10;15:15:15.557 [AWT-EventQueue-0] DEBUG com.infolytik.ui.metaminer.Zdz - HTTP Response size: 7
02.10;15:15:15.557 [nioEventLoopGroup-3-16] DEBUG com.infolytik.ui.metaminer.Zct - channelInactive: method /RemoteServer.getTabSnapshotTimestamp(long) channel 5c145d5a closed.

MMC Loader Log

This is the log of the Windows OS executable which runs MMC. The loader sends logging information to stdout and stderr streams. This information is then written to a log file.
Appender STDOUT, STDERR
Config MetaMiner.ini and MetaMiner.logback.xml
Ini config variable log
Default Output console, redirected to a file
Default Filename client.start.log
Default Level DEBUG
Default Encoder (format) %-4relative [%thread] %-5level %logger{35} - %msg %n

Example: 

[info] Module Name: C:\Program Files\Infolytik\MetaMiner\client\MetaMiner.exe
[info] Module INI: C:\Program Files\Infolytik\MetaMiner\client\MetaMiner.ini
[info] Module Dir: C:\Program Files\Infolytik\MetaMiner\client\
[info] INI Dir: C:\Program Files\Infolytik\MetaMiner\client\
[info] Working directory set to: C:\Program Files\Infolytik\MetaMiner\client
[info] Displaying splash: res\splash_metaminer.jpg
[info] Configured vm.location: ..\jre\bin\server\jvm.dll
[info] Found VM: C:\Program Files\Infolytik\MetaMiner\jre\bin\server\jvm.dll
[info] Expanding Classpath: lib\*.jar

Note

Encoder (format) settings cannot be applied to log event messages from the loader itself. They are always in the [%level] %msg format. See several first lines in the example above.

Garbage Collector Log

The log for Java Garbage Collector (GC) of MMC JVM. Optional.
Config MetaMiner.ini
Variable Xloggc
Default Filename gc-<timestamp>.log.N.current
Default Rotation/Retention none
Format {Heap before GC invocations ... DATETIME ... Heap after GC invocations ... }
