[SOLVED] How to see PM2 restart history (node-pm2)

How to see PM2 restart history (node-pm2)

Is it possible to see the restart log/history with PM2 app?

I saw my nodeJS app restarted a few times but no clue when.

I've checked pm2 documentation but no luck.

Solution

PM2's own logs are streamed into the file ~/.pm2/pm2.log

Example commands for viewing:

cat ~/.pm2/pm2.log
tail -n 30 ~/.pm2/pm2.log - last 30 lines
watch -n 1 tail -n 30 ~/.pm2/pm2.log - last 30 lines, live-updated once per second

Example output:
