newrelic-management

• Provides functionality not inherently available through the NewRelic UI

The goal here is to allow servers to be added to alert conditions based on tag. For some reason, NewRelic does not allow much dynamicism in this regard.

Additionally, non-reporting, stale servers can build up in the NewRelic console. Let's create a programmatic solution to remove servers that haven't reported recently or in X-amount of time.

• Adding & Excluding Servers from Alerts, based on:

  • Tag
  • Server Name
  • Server ID

• Automatic Removal of Stale, Non-Reporting Servers

• Running either of the above functions in a daemonized, periodic fashion, e.g. every 10 minutes.

{
  "nr_api_key": "abc123def456",
  "cleanup": true,
  "cleanup_interval": "5m",
  "alert_management_interval": "5m",
  "alerts": [
    {
      "name": "Disk Space",
      "match_any": true,
      "labels": [
        "Environment:Production",
        "Environment:Staging"
      ]
    },
    {
      "name": "RAM Utilization",
      "match_any": true,
      "labels": [
        "Environment:Production",
        "Environment:Staging"
      ],
      "exclude": [
        "Role:Consumers",
        "Role:ETL"
      ]
    },
    {
      "name": "Production - DB",
      "labels": [
        "Environment:Production",
        "Role:Database"
      ]
    }
  ]
}

If daemonizing, you should lock down permissions on all configuration files in this project to only the user which this runs as...

Add this line to your application's Gemfile:

gem 'newrelic-management'

And then execute:

$ bundle

Or install it yourself as:

$ gem install newrelic-management

$ newrelic-management -c /path/to/config.json

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
