Validation Tracker

Monitors rippled logs and parses out validation events from the network nodes

In addition to the database-specific environment variables the following must be set:

• RIPPLED_LOG_PATH - [debug_logfile] in rippled.cfg

Description

The core class is RippledLogMonitor which tails the rippled logs and parses out validation events, formatting them as JSON and logging to the console.

To extend the monitor functionality create a subclass of RippledLogMonitor and override the onValidation(validation) method.

By default validation-tracker will exit without a database option specified

Development

Local VM Setup

Use vagrant to provision a local virtual machine with validation-tracker installed. By default the Vagrantfile provides an ansible-based provisioner. Please install VirtualBox before provisioning the development environment

vagrant up --provision

The above command will start a new virtual machine based on ubuntu 14.04 64-bit using VirtualBox and run the vagrant play to provision the validation-tracker.

Ansible Vault Password Prompt

Environment variables are encrpyted in ansible/vault/development.yml and you will be prompted to enter in the password for ansible vault. The password for is password12345

Modifying Source Code
