You may want to modify some of the configuration properties in production environments to optimize performance, based on your site’s load characteristics. To help aid in this across all the logging services there is a global component at /atg/reporting/Configuration, which has a set of properties that the different logging services link to. This lets you change logging behavior for logging services globally, rather than changing the configuration of each logging service separately. The following table describes the properties that you can globally configure:

Property Name



Flag to determine if the logging operations should be enabled. To disable all logging for the server set this to false.

Default: true


The number of items to log at once (in a batch).

Default: 10


The schedule that the SQL loggers should use to periodically flush their data to the database.

Default: every 10 minutes in 10 minutes


The number of log entries to collect before generating a summarized log entry.

Default: 100


The schedule that the summarizers should use to output their current statistics.

Default: every 10 minutes in 10 minutes


Schedule to determine when the log files should be rotated. (See the Core Dynamo Services chapter in the ATG Programming Guide.) The default setting has the logs rotated every day at 1am.

Default: calendar * * * 1 0


How many log entry IDs should be reserved in one batch.

Default: 100


The directory in which to place all the log data files.

Default: logs


The centralized ATG scheduler service.

Default: /atg/dynamo/service/Scheduler


Adds a time-stamp to all the names of the log files.

Default: true


Uses this extension for the log file.

Default: data


Format for the time stamp, based on java.text.SimpleDateFormat. The default value formats dates by month-day-year_hour-minute_second-millisecond.

Default: MM-dd-yyyy_HH-mm-ss-SS
