The log files are usually rotated to avoid oversizing a single log file.
Default Rotation Policy
The current policy used by OpenResty Edge is to rotate log files based on time. The time interval is 3600 seconds, and the maximum number of files retained is 128. This means that Edge will generate 1 log file every 1 hour (3600 seconds).
Log file naming format:
# error.log_yyyymmdd.HHMMSS error.log_20220922.090000
Modify the rotation policy
number of log files to keep can then be configured on the Admin’s Web UI as follows:
[Global Config] - [General] - [Log]
rotation interval can be configured via the
[rotate_log] interval = 3600
