Installation

Berkshelf is recommended to install this cookbook. In fact, it's recommended to install all your cookbooks! Within your Berksfile

cookbook 'monit', git: 'https://github.com/axsuul/cookbook-monit'

Recipes

Some monit configuration recipes have also been provided for some popular services.

default

Installs monit as a service using the package manager and drops off a monitrc configuration file. Make sure to check out the default attributes file!

Usage

A monit resource is provided to easily manage monit configurations. Here's a simple example

monit "postgresql" do
  pidfile "/var/run/postgresql/9.1-main.pid"
  start "/etc/init.d/postgresql start"
  stop "/etc/init.d/postgresql stop"
end

Default action is :enable. You can disable by doing

monit "postgresql" do
    # ...
    action :disable
end

What happens if you want to run the process as a user? The monit resource provides a helper attribute as and will load that user's environment while running the start and stop commands.

monit "sidekiq" do
  pidfile "/app/pids/sidekiq.pid"
  start "/app/bin/sidekiq --pidfile /app/pids/sidekiq.pid"
  as "deployer"
  conditions [
    "if mem > 256 MB for 1 cycles then restart",
    "if cpu > 90% for 5 cycles then restart",
    "if 5 restarts within 5 cycles then timeout"
  ]
end

You still have the option to run the commands directly as the user (without environment) with uid and gid, although most likely you will want to use as.

monit "sidekiq" do
  pidfile "/app/pids/sidekiq.pid"
  uid "deployer"
  gid "admin"
  # ...
end

Notice that in the above example, stop is not set. If stop is not set, the provider will use a SIGTERM to kill the pid in the pidfile.

No pidfile?. No worries bro!

monit "varnish" do
  matching "varnishd"
  # ...
end
