A flexible process monitoring and management framework.
Curator.js is a flexible process monitoring and management framework written in coffeescript and run on top of node.js.
Curator provides interfaces to control and monitor processes and process groups. Each process is tied to an object called a "watch instance." Curator also provides a watchGroup object that represent a group of processes, which can be dynamically configured.
You can install Curator.js using npm.
npm install curator
Here is a simpliest task in Curator, creating a auto-restart job.
Curator = require 'curator'myWatch = CuratornewWatch ->@name = 'my-watch-instance'@startCommand = 'some-command' # Change this as you like.@on 'data'Curatorprint # Print process' STDOUT.@use CuratorautoRestart # Apply autoRestart module to this instance.myWatchstart
Of course, you can also set
@maxRetry if you like.
For more examples please see examples/*
The structure of the Curator project consists of three main parts: core, system, and modules. Core is the small set of code that implements watch and watchGroup. System is the part where Curator interacts with system level API like doing procfs lookups. Modules are parts that extend and define the behaviors of watch and watchGroup instances. You can easily extend Curator by writing custom modules.
Curator is written in coffee-script. All source code is located under
directory. After you make some change in
cake build. Make sure you run
vows to test out your change.
