Line protocol

InfluxDB accepts data via HTTP, TCP, and UDP. It defines a line protocol backwards compatible with Graphite and takes the form:

measurement(,tag_key=tag_val)* field_key=field_val(,field_key_n=field_value_n)* (nanoseconds-timestamp)?

Retention policy

When you create a database, InfluxDB creates a retention policy called autogen with an infinite duration, a replication factor set to one, and a shard group duration set to seven days.
