Writing advanced adapters

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
• KHIKA Data Aggregator pipes the output of the Aggregator script and send it to KHIKA over a SSL connection
