After understanding Khika Data Format and going through the initial exercise of Writing you own KHIKA Data Adapters , it is the time to create a production level KHIKA Adapter. A few points to note here before we begin writing our own Adapter:

  • Adapters are scripts that execute on KHIKA Data Aggregator
  • Adapters can be written in any programming language (our favorite is python 2.7)
  • Adapters are scheduled processes and KHIKA Data Aggregator is responsible for scheduling them to run at a periodic interval (typically 1 minute to 5 minutes)
  • The Adapter scripts
    • read the raw log messages one-by-one (from source such as files, queues, APIs, Databases etc),
    • parse the log messages,
    • convert it in [ Khika Data Format]
    • Write the output to stdout
