CrateDB Output Plugin for Telegraf
This plugin writes to CrateDB via its PostgreSQL protocol.
Table Schema
The plugin requires a table with the following schema.
CREATE TABLE my_metrics (
"hash_id" LONG INDEX OFF,
"timestamp" TIMESTAMP,
"name" STRING,
"tags" OBJECT(DYNAMIC),
"fields" OBJECT(DYNAMIC),
PRIMARY KEY ("timestamp", "hash_id","day")
) PARTITIONED BY("day");
The plugin can create this table for you automatically via the table_create
config option, see below.
Configuration

# Timeout for all CrateDB queries.

# Name of the table to store metrics in.
