Bug ID 683271: Logrotate behavior of application connector service center

Last Modified: Apr 28, 2025

Affected Product(s):
Application Connector TMOS(all modules)

Known Affected Versions:
1.1.0, 1.1.1

Opened: Sep 13, 2017

Severity: 3-Major

Symptoms

Application Connector Service Center uses the Winston logging system and writes output to app_connX.log files. It is configured to use up to 3 output files, max size 10MB. The log rotation iterates from app_conn.log to app_conn2.log to app_conn3.log, then it switches back to app_conn.log, repeating as necessary. Due to this behavior, make sure you are looking at the app_conn.log* file with the most recent timestamp to see the most recent logs from the service center.

Impact

The most recent log file might not be named app_conn.log - make sure you look at the timestamps of the log files, and tail the most recent one accordingly.

Conditions

Log rotation occurs when Application Connector Service Center is configured and has logged more than 10MB of data.
