Tornimo is a Graphite compatibile platform. It allows you to send data using the same methods as you would use while sending it to graphite. During onboarding you are provided with your private tornimo token and url for data ingestion.
Tornimo has got really easy plain-text tcp protocol that goes as follows:
<token>.<metric-name> <value> <timestamp>\n
bed1057b-0595-4246-90df-12da5252b422.application.query.time.max 1000 1546297200000\n
Timestamp can be either in milliseconds or seconds (it will be internally normalized to one format). It could be written directly to tcp socket on 2003 port. In this section there are examples on how to write to Tornimo in some different languages.
