Log rotation

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 default maximum number of files retained is 168. This means that Edge generates one log file every hour for each configured log category.

Log file naming format:

# error.log_yyyymmdd.HHMMSS
error.log_20220922.090000

# Modify the rotation policy

The Maximum number of log files to keep can be configured in Edge Admin at:

[Global Config] - [General] - [Log]

The Edge Admin form accepts 4–2048. The Admin API accepts 1–2048 for compatibility. A per-file EdgeLang set-access-log(max-kept:) value takes precedence over this global value; when it is omitted, the global value applies.

The rotation interval can be configured via the config.ini file:

/usr/local/oredge-node/conf/config.ini

[rotate_log]
interval = 3600

Do not reduce retention without checking hourly volume, available disk space, incident-response requirements, and external log shipping. Gzip-compressed access logs can be read with zcat.
