This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pm2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Main features

Process management

Once apps are started you can list and manage them easily:

Process listing

Listing all running processes:

$ pm2 list

Managing your processes it's straightforward:

$ pm2 stop     <app_name|id|all>

Log facilities

Monit

Displaying logs of a specified process or all processes, in real time:

$ pm2 logs
$ pm2 logs big-api
$ pm2 flush          # Clear all the logs

Load balancing / 0s reload downtime

When an app is started with the -i option, the cluster mode is enabled.

With the cluster mode, PM2 enable load balancing between each worker. Each HTTP/TCP/UDP request will be forwarded to a specific process at a time.

$ pm2 start app.js -i max  # Enable load-balancer and cluster features

$ pm2 reload all           # Reload all apps in 0s manner

Startup script generation

PM2 can generate and configure a startup script to keep PM2 and your processes alive at every server restart.

$ pm2 startup <ubuntu|centos|gentoo|systemd>

To save a process list just do:

$ pm2 save
