Session Log Rollover

Session Log Rollover

You can limit the size of session log files for real-time sessions. Configure a maximum log file size for the session log. When the session log reaches a maximum size, the Integration Service creates a new log file and writes the session logs to the new log file. When the session log is contained in multiple log files, each file is a partial log.
Configure the session log to roll over to a new file after the log file reaches a maximum size. Or, configure the session log to roll over to a new file after a maximum period of time. The Integration Service saves the previous log files.
You can configure the maximum number of partial log files to save for the session. The Integration Service saves one more log file that the number of files you configure. The Integration Service does not purge the first session log file. The first log file contains details about the session initialization.
The Integration Service names each partial session log file with the following syntax: 
<session log file>.part.n
Configure the following attributes on the Advanced settings of the Config Object tab:
  • Session Log File Max Size
    . The maximum number of megabytes for a log file. Configure a maximum size to enable log file rollover by file size. When the log file reaches the maximum size, the Integration Service creates a new log file. Default is zero.
  • Session Log File Max Time Period
    . The maximum number of hours that the Integration Service writes to a session log. Configure the maximum time period to enable log file rollover by time. When the period is over, the Integration service creates another log file. Default is zero.
  • Maximum Partial Session Log Files.
     Maximum number of session log files to save. The Integration Service overwrites the oldest partial log file if the number of log files has reached the limit. If you configure a maximum of zero, then the number of session log files is unlimited. Default is one.
You can configure a combination of log file maximum size and log file maximum time. You must configure one of the properties to enable session log file rollover. If you configure only maximum partial session log files, log file rollover is not enabled.
