@jessety/pm2-logrotate

NOTE: This is a fork of pm2-logrotate, which is (currently) unmaintained. It fixes a critical issue that prevented any log files from being deleted on Windows, which was affecting pm2-installer.

Description

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

Install

pm2 install @jessety/pm2-logrotate

NOTE: the command is pm2 install NOT npm install

Configure

  • 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.

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:compress true (compress logs when rotated)
  • pm2 set pm2-logrotate:rotateInterval '*/1 * * * *' (force rotate every minute)
