Description

PM2 module to automatically rotate logs of processes managed by PM2.

Install

pm2 install pm2-logrotate

Configure

There are 3 values that you need to configure :

• max_size (Defaults to 10MB): When a file size becomes higher than this value it will split it. You can specify the unit at then end: 10G, 10M, 10K
• interval (Defaults to 1):
• interval_unit (Defaults to 'DD'): interval and interval_unit works together, it means if you have interval_unit='DD' and interval=3, it will split the logs every 3 days.
• retain (Defaults to all): This number is the number of rotated logs that are keep at any one time, it means that if you have retain = 7 you will have at most 7 rotated logs and your current one.

Possible values for interval_unit are 'MM' (months), 'DD' (days), 'mm' (minutes). eg: interval:9, interval_unit:'mm' will split the logs every 9 minutes.

How to set these values ?

• After having installed the module you have to type : pm2 set pm2-logrotate:<param> <value>

e.g: pm2 set pm2-logrotate:max_size 1K (1KB) pm2 set pm2-logrotate:interval_unit 'MM' (Months)
