CTO-AIPA Restarts and Log Silence: A Production Mystery

Описание и применение

Процесс cto-aipa часто перезапускается, но логи отсутствуют. Добавление детального логирования, мониторинга ресурсов и проверка последних коммитов помогут выявить причину и устранить проблему.

Задача

The cto-aipa process restarts 151 times in a day while PM2 reports it as online, yet no logs are produced to explain the failures.

Результат

By adding granular logging, monitoring resource usage, and reviewing recent code changes, the silent restarts can be traced to a specific failure point, allowing the team to fix the issue and restore stability.

Рабочий процесс

• Add try-catch blocks around critical operations and log exit points
• Enable detailed PM2 error logging and review pm2 logs
• Set up real-time memory and CPU monitoring (e.g., using pm2 monit or external tools)
• Inspect recent commits in dependent repositories for potential breaking changes
• Analyze PM2 configuration for any suppression of logs
• Iteratively test and verify that restarts produce logs and identify the trigger

Доказательства

My cto-aipa process has restarted 151 times today. It's currently up 0d, according to pm2 jlist. This is a significant number of restarts for a process that should be stable, yet my logs for cto-aipa are silent.

Adding more granular logging: Implementing try-catch blocks around critical operations and ensuring all potential exit points log their status.
