Listening to Bitcoin network with Splunk

This is a simple system for Splunking Bitcoin network and showing interesting metrics for Bitcoin economy.

It is consisted of two components:

• A Bitcoin node for downloading Bitcoin block chain and listening Bitcoin block chain events via the Bitcoin P2P network
• A Vagrant nvironment for setting up Splunk and importing the Bitcoin logging data generated by the Bitcoin node above

To set it up (only verified under Mac OS X 10.9):

• git clone this Github repository
  • let's call the repository folder SPLUNKING_BITCOIN_HOME
  • and call the SPLUNKING_BITCOIN_HOME/src/vagrant/splunk/assets folder as ASSETS folder
• Download Splunk
  • you need to download the Linux x64 for RedHat edition (an RPM package)
  • put the downloaded RPM package under the ASSETS folder
• Download Bitcoin bootstrap.dat file
  • this is used for fast syncing the block chain
  • you need to use some BitTorrrent software to download it
  • please put it under the ASSETS folder
• Download and install Vagrant
• Download and install Apache Maven
• Start the Bitcoin node for block chain syncing and listening
  • Enter SPLUNKING_BITCOIN_HOME directory, run "mvn exec:java"
• Install Splunk license
  • Copy your Splunk license file to the ASSETS folder and name it splunk.license
• Use vagrant to set up the entire environment
  • Enter SPLUNKING_BITCOIN_HOME/src/vagrant directory, run "vagrant up"
• That's it
  • you can use your browser to nagivate to http://192.168.33.9:8000 (admin:999admin) to use Splunk Web to explore the data
