PdMetrics

Library to send metrics to Logstash, which then delivers them to PagerDuty's metric systems. This is pretty much only useful if you're a PagerDuty employee.

Installation

Add this line to your application's Gemfile:

gem 'pd_metrics'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pd_metrics

Usage

# Captures timing metrics for a block of Ruby code.
PdMetrics.time('api', 'receive_email', account: 'Netflix') do
  # process the email
end

# Captures an increase/decrease in a counter.
PdMetrics.incr('emails', 'bytes_received', email_bytes.size, account: 'Netflix')

# Captures the current value for a metric.
PdMetrics.gauge('ruby', 'live_objects', ObjectSpace.live_objects)

# Captures statistical metrics for a set of values within a given timeframe.
# This is very similar to the time method, but it's genericized for use in
# arbitrary values.
PdMetrics.histogram('api', 'payload_size', payload.size, account: 'Netflix')
