strong-pm - Process Manager

StrongLoop PM is a production process manager for Node.js applications with built-in load balancing, monitoring, multi-host deployment, and a graphical console.

For more details, see http://strong-pm.io

Installation

Requirements: git needs to be installed

Install the client-side CLI and GUI (slc arc):

npm install -g strongloop
slc -h

Run app

slc start app.js

Or to deploy and manage remotely, install the manager on a production server using npm:

npm install -g strong-pm && sl-pm-install

Or using docker:

curl -sSL http://strong-pm.io/docker.sh | sudo /bin/sh

Quick Start

Under production, you will install the process manager as a system service, see http://strong-pm.io/prod, but if you are just trying the manager out locally, you can run an app directly from the command line.

Get a sample app (or use your own app):

git clone [e-mail]:strongloop/express-example-app.git
cd express-example-app
npm install

Start the app under the process manager:

slc start

Interact with the app using the StrongLoop GUI:

slc arc

See http://strong-pm.io for more information.

Features

• Profile CPU to find event loop stalls
• Profile memory to find leaks
• View performance metrics on your application
• Use graphical tool or CLI
• Docker support

Great for production!

• Supports remote deploy and management
• Git-based deploy for easy deployment versioning and rollback
• Deployment does not have external dependencies (production hosts don't have to fetch from npmjs.org or Git)
• Docker support
• Built and supported by Node core maintainers at StrongLoop, battle-tested by enterprise customers

Build & Deploy

• Multi-host deploy
• Zero-downtime application restarts and upgrades
• Install dependencies, run custom build steps, and prune development dependencies without affecting your source tree
• SSH, HTTP, or Git-based deploy

Profile

• Heap snapshots and CPU profiles
• Profile applications to find performance bottlenecks
• Use StrongLoop's unique event loop triggered profiling to start CPU profiling when the Node event loop stalls

Manage processes and clusters

• Use all available CPU cores
• Automatic restart on failure
• Log aggregation and management
• Change cluster size, view clustering info remotely
• Set up secure access via SSH / HTTPS
• Manage Nginx load-balancer for multi-host deployments

Metrics

• View performance metrics such as event loop times, CPU and memory consumption
• Publish metrics to StatsD-compatible servers, and view in 3rd-party consoles such as:
  • DataDog
  • Graphite
  • Splunk
  • Even syslog and raw log files
  • See Integrating with third-party consoles for details.
• Third-party probe metrics, for example for Memcached, MongoDB, Redis, MySQL, and so on.
