FTS Server log

You can troubleshoot the FTS Server by configuring and viewing the FTS Server logs. The FTS Server generates logging information during server startup, indexing, and searching. The log files contain configuration information, warnings, errors, and debugging information that can be useful for monitoring the server and for troubleshooting specific issues. The command-line tools also generate log files. By default, log files are stored in the FTS_Home/log directory. You can run the configTool with the list -logFolder command to see your log directory.

Every message in the log file has an associated level that indicates the message type. The logging levels, in descending order of severity, are defined:
  • SEVERE: Errors and exceptions that occur while the server is running. Typically, SEVERE messages include detailed information with the stack trace.
  • WARNING: Mild problems that might require the attention of an administrator, such as a missing value for a setting with a default value, or the truncation of a document during indexing.
  • INFO: Informational messages that are generated during system operation.
  • FINE: Detailed messages for debugging purposes. This level includes parsed queries.
  • FINER: More details, for example, the results of document parsing.
  • FINEST: The most detailed level.

The default logging level is INFO, which means that messages of levels SEVERE, WARNING, and INFO are generated. To view the current logging level, run the FTS Server adminTool with the printLogLevel command. To change the logging level at run time, run the adminTool with the configureTrace -logLevel command.
