C.2.20. Lots of entries added to replicator log

Last Updated: 2015-06-01

Condition or Error

The logging level used by Tungsten Clustering creates a lot of entries, including WARN, this generates a lot of information that is difficult to find the real errors and problems. How do i change the logging level?

Causes

  • By default, Tungsten Clustering reports a lot of information and detail, including INFO and other levels of detail that may generate a lot of information. For example:

    INFO | jvm 1 | 2016/02/18 10:16:46 | 2016-02-18 15:16:46,789 [brm - remote-to-thl-0] WARN filter.ReplicateFilter Ignoring query : No schema found for this query from event 4020717251 (SET @current_db_user := NULL...)

Rectifications

  • The logging level used to report status and other information, and that is written into the log, can be changed to reduce or lower the reporting level. To do this:

    1. Edit the ~tungsten_home/tungsten/tungsten-replicator/conf/log4j.properties

    2. Find the following line:

      log4j.logger.com.continuent.tungsten.replicator.filter.ReplicateFilter=DEBUG, stdout

    This will change the logging level so that only entries at DEBUG and higher will be output.
