Logs & Cron Maintenance

Configuration options

• pcn_log_table_max: maximum number of rows to keep in the DB table (default 1000). Set to 0 for no limit.
• pcn_logs_option_limit: when falling back to wp_options for log storage, the maximum number of entries to keep (default 200) to avoid oversized options.

Implementation details

• The plugin will attempt to create and write to the {$wpdb->prefix}pcn_email_logs table when sending emails; if table creation or write fails it will fall back to pcn_email_logs option.
• To prevent unbounded growth, PCN_Settings::enforce_log_limits() performs:
  • Truncate the pcn_email_logs option, keeping only the latest N entries (pcn_logs_option_limit).
  • Delete oldest rows from the DB table to ensure the row count does not exceed pcn_log_table_max.

Scheduling

• The plugin schedules a daily event pcn_daily_maintenance on activation; that event calls PCN_Settings::enforce_log_limits().
• Manual run (WP-CLI):

wp eval 'PCN_Settings::enforce_log_limits();'

Cleanup & export

• Admin UI offers clear logs and export CSV operations; export supports filtering by number of days (0 for all).
• Recommendation: export and archive logs for long-term retention, then set a reasonable pcn_log_table_max.
