Logstash OpenWhisk input plugin

This Logstash input plugin allows you to drain Activation logs from OpenWhisk. The HTTP polling service uses the OpenWhisk API to retrieve logs, according to a user-defined schedule. Each activation instance is decoded to an event and forwarded into the system.

This plugin is based off logstash-input-http_poller.

Config Example

input {
  openwhisk {
    # Mandatory Configuration Parameters
    hostname => "openwhisk.ng.bluemix.net"
    username => "sample_user@email.com"
    password => "some_password"
    # Supports "cron", "every", "at" and "in" schedules by rufus scheduler
    schedule => { "every" => "15m"}

    # Optional Configuration Parameters
    # Namespace is optional, defaults to user's default namespace.
    namespace => ""
    request_timeout => 60
    codec => "json"
    # A hash of request metadata info (timing, response headers, etc.) will be sent here
    metadata_target => "http_poller_metadata"

output {
  stdout {
    codec => rubydebug

For configuration documentation, see openwhisk.rb in lib/logstash/inputs/ in this repo.

This plugin uses the Rufus scheduler to manage the polling request schedule. The schedule parameter is parsed by this module and supports all the valid scheduling directives.

More configuration files using this plugin are available in examples.


$ bin/logstash-plugin install logstash-input-openwhisk

Docker Example

See the examples/docker folder for details on building a Docker image for the Elasticsearch, Logstash and Kibaba with the Openwhisk plugin installed.

1. Plugin Developement and Testing


  • To get started, you'll need JRuby with the Bundler gem installed.

  • Create a new plugin or clone and existing from the GitHub logstash-plugins organization. We also provide example plugins.

  • Install dependencies

bundle install


  • Update your dependencies
bundle install
  • Run tests
bundle exec rspec

2. Running your unpublished Plugin in Logstash

2.1 Run in a local Logstash clone

  • Edit Logstash Gemfile and add the local plugin path, for example:
gem "logstash-input-openwhisk", :path => "/your/local/logstash-input-openwhisk"
  • Install plugin
# Logstash 2.3 and higher
bin/logstash-plugin install --no-verify

# Prior to Logstash 2.3
bin/plugin install --no-verify
  • Run Logstash with your plugin
bin/logstash -e 'input {openwhisk {...}}'

At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.

2.2 Run in an installed Logstash

You can use the same 2.1 method to run your plugin in an installed Logstash by editing its Gemfile and pointing the :path to your local plugin development directory or you can build the gem and install it using:

  • Build your plugin gem
gem build logstash-input-openwhisk.gemspec
  • Install the plugin from the Logstash home
# Logstash 2.3 and higher
bin/logstash-plugin install --no-verify

# Prior to Logstash 2.3
bin/plugin install --no-verify
  • Start Logstash and proceed to test the plugin
