queue-triage

An application to manage dead lettered messages across multiple brokers

Building

• JDK 8
• Mongo 3.2+
• Gradle. Please refer to the Getting Started Guide for installation and usgae of Gradle.

Setup

To configure the project for IntelliJ run:

./gradlew idea

To create the relevant Mongo Roles and Users execute the following (this assumes Mongo is running locally on port 27017 and an admin user exists with password Passw0rd. These values can be overridden using environment variables, see mongo-queue-triage-roles.sh or mongo-queue-triage-users.sh):

./gradlew createUsersAndRoles

Testing

To test all the modules run the following commands:

./gradlew test

Testing - Configuration

The web component-test will run against a local firefox. There are a number of options that can be configuration by adding passing in parameters to the build.

browser

Execute the selenium tests against a given browser

./gradlew test -Pbrowser=firefox|phantomjs

remote_url

Can be used to execute the selenium tests against a remote selenium instance

./gradlew test -Pselenium.remote_url=http://localhost:4444/wd/hub

Starting

To run the queue-triage-core-server from the command line run:

./start.sh core

To run the queue-triage-web-server from the command line run:

./start.sh ldap
./start.sh web

Troubleshooting

External Dependencies

Your organisation may not allow direct access to the Central Maven repository (https://repo1.maven.org/maven2), if this is the case you will need to create a second "local" configuration file (filename: ~/.gradle/init.gradle) in the project's root directory and the following snippet to the init.gradle file:

allprojects {
  repositories {
    maven {
	  url "https://repo.internal.com/maven2"
    }
  }
}

where https://repo.internal.com/maven2 is your internal local repo location.

NOTE: This file should not be under version-control.

###Releasing The axion-release plugin is used to apply semantic versioning to the project after successful builds. You can view more detailed documentation on their website but here is the TL;DR

To inspect what version your current codebase is running against:

./gradlew currentVersion

To release a new version of the committed and pushed code, then execute:

./gradlew release

If you'd like to test these options out, then you can run in dry-run mode:

./gradlew release -Prelease.dryRun

Message Classification

Message Classification is really the core of the queue-triage application.

Once a messages has been Dead-Lettered by an Application, queue triage:

• De-queues the message
• Classifies the message using a set of Predicates
• Performs one or more Actions
