Application Insights SDK for Ruby

Gem Version

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. -- Ruby - Official Site

This project extends the Application Insights API surface to support Ruby. Application Insights is a service that allows developers to keep their application available, performing and succeeding. This Ruby gem will allow you to send telemetry of various kinds (event, trace, exception, etc.) to the Application Insights service where they can be visualized in the Azure Portal.

Requirements

Ruby 1.9.3 is currently supported by this gem.

Installation

To install the latest release you can use gem.

$ gem install application_insights

Usage

Once installed, you can send telemetry to Application Insights. Here are a few samples.

Note: before you can send data to you will need an instrumentation key. Please see the Getting an Application Insights Instrumentation Key section for more information.

###Sending a simple event telemetry item###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
tc.context.instrumentation_key = '<YOUR INSTRUMENTATION KEY GOES HERE>'
tc.track_event 'My event'
tc.flush

###Sending an event telemetry item with custom properties and measurements###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
tc.context.instrumentation_key = '<YOUR INSTRUMENTATION KEY GOES HERE>'
tc.track_event 'My event', :properties => { 'custom property' => 'some value' }, :measurements => { 'custom metric' => 13 }
tc.flush

###Sending a trace telemetry item with custom properties###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
tc.context.instrumentation_key = '<YOUR INSTRUMENTATION KEY GOES HERE>'
tc.track_trace 'My trace statement', :properties => { 'custom property' => 'some value' }
tc.flush

###Sending a metric telemetry item (without and with optional values)###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
tc.context.instrumentation_key = '<YOUR INSTRUMENTATION KEY GOES HERE>'
tc.track_metric 'My metric', 42
# with all optional values set
tc.track_metric 'My metric', 42, :kind => ApplicationInsights::Channel::Contracts::DataPointType::AGGREGATION, :count => 3, :min => 1, :max => 100, :std_dev => 10, :properties => { 'custom property' => 'some value' }
tc.flush

###Sending an exception telemetry item with custom properties and measurements###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
tc.context.instrumentation_key = '<YOUR INSTRUMENTATION KEY GOES HERE>'
begin
  raise ArgumentError, 'Something has gone wrong!'
rescue => e
  tc.track_exception e
end
tc.flush

###Configuring context for a telemetry client instance###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
tc.context.instrumentation_key = '<YOUR INSTRUMENTATION KEY GOES HERE>'
tc.context.application.id = 'My application'
tc.context.application.ver = '1.2.3'
tc.context.device.id = 'My current device'
tc.context.device.oem_name = 'Asus'
tc.context.device.model = 'X31A'
tc.context.device.type = "Other"
tc.context.user.id = 'santa@northpole.net'
tc.track_trace 'My trace with context'
tc.flush

###Configuring synchronous (default) channel properties###

require 'application_insights'
tc = ApplicationInsights::TelemetryClient.new
# flush telemetry if we have 10 or more telemetry items in our queue
tc.channel.queue.max_queue_length = 10
# send telemetry to the service in batches of 5
tc.channel.sender.send_buffer_size = 5

###Configuring an asynchronous channel instead of the synchronous default###

require 'application_insights'
sender = ApplicationInsights::Channel::AsynchronousSender.new
queue = ApplicationInsights::Channel::AsynchronousQueue.new sender
channel = ApplicationInsights::Channel::TelemetryChannel.new nil, queue
tc = ApplicationInsights::TelemetryClient.new channel
# Note: the event will be sent on a separate thread; if the app finishes before
#       the thread finishes, the data is lost
tc.track_event 'My event'

###Configuring asynchronous channel properties###

require 'application_insights'
sender = ApplicationInsights::Channel::AsynchronousSender.new
queue = ApplicationInsights::Channel::AsynchronousQueue.new sender
channel = ApplicationInsights::Channel::TelemetryChannel.new nil, queue
tc = ApplicationInsights::TelemetryClient.new channel
# flush telemetry if we have 10 or more telemetry items in our queue
tc.channel.queue.max_queue_length = 10
# send telemetry to the service in batches of 5
tc.channel.sender.send_buffer_size = 5
# the background worker thread will be active for 5 seconds before it shuts down. if
# during this time items are picked up from the queue, the timer is reset.
tc.channel.sender.send_time = 5
# the background worker thread will poll the queue every 0.5 seconds for new items
tc.channel.sender.send_interval = 0.5

###Collecting unhandled exceptions###

require 'application_insights'
# setup unhandled exception handler
ApplicationInsights::UnhandledException.collect('<YOUR INSTRUMENTATION KEY GOES HERE>')
# raise an exception and this would be send to Application Insights Service
raise Exception, 'Boom!'
