ClickHouse configuration

  1. Add graphite_rollup section to config.xml. Sample here.

  2. Create tables

CREATE TABLE graphite ( 
  Path String,  
  Value Float64,  
  Time UInt32,  
  Date Date,  
  Timestamp UInt32
) ENGINE = GraphiteMergeTree(Date, (Path, Time), 8192, 'graphite_rollup');
 
-- optional table for faster metric search
CREATE TABLE graphite_tree (
  Date Date,
  Level UInt32,
  Path String,
  Deleted UInt8,
  Version UInt32
) ENGINE = ReplacingMergeTree(Date, (Level, Path), 8192, Version);

GraphiteMergeTree documentation

You can create Replicated tables. See [ClickHouse documentation](https://clickhouse.yandex/reference_en.html#Data replication)
