Module to rotate logs of every pm2 application
npm install pm2-logrotate-legacy-nodejsPM2 module to automatically rotate logs of processes managed by PM2.
pm2 install pm2-logrotate
NOTE: the command is pm2 install NOT npm install
- max_size (Defaults to 10M): When a file size becomes higher than this value it will rotate it (its possible that the worker check the file after it actually pass the limit) . You can specify the unit at then end: 10G, 10M, 10K
- retain (Defaults to 30 file logs): 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.
- compress (Defaults to false): Enable compression via gzip for all rotated logs
- dateFormat (Defaults to YYYY-MM-DD_HH-mm-ss) : Format of the data used the name the file of log
- rotateModule (Defaults to true) : Rotate the log of pm2's module like other apps
- workerInterval (Defaults to 30 in secs) : You can control at which interval the worker is checking the log's size (minimum is 1)
- rotateInterval (Defaults to 0 0 * everyday at midnight): This cron is used to a force rotate when executed.
We are using node-schedule to schedule cron, so all valid cron for node-schedule is valid cron for this option. Cron style :
- TZ (Defaults to system time): This is the standard tz database timezone used to offset the log file saved. For instance, a value of Etc/GMT+1, with an hourly log, will save a file at hour 14 GMT with hour 13 (GMT+1) in the log name.

pm2 set pm2-logrotate:
e.g:
- pm2 set pm2-logrotate:max_size 1K (1KB)pm2 set pm2-logrotate:compress true
- (compress logs when rotated)pm2 set pm2-logrotate:rotateInterval '/1 *'` (force rotate every minute)
-
