Graphite-InfluxDB

An influxdb (0.8-rc5 or higher) backend for Graphite-web (source or 0.10.x) or graphite-api.

Install and configure using docker

Using docker is an easy way to get graphite-api + graphite-influx up and running. See https://github.com/Dieterbe/graphite-api-influxdb-docker

Otherwise, follow instructions below. Graphite-api is the simplest to setup, though graphite-web might perform better. You can use the experimental statsd support in graphite-api to have this backend submit performance metrics (not supported with graphite-web)

Manual installation

pip install graphite_influxdb

About the retention schemas

In the configs below, you'll see that you need to configure the schemas (datapoint resolutions) explicitly. It basically contains the same information as /etc/carbon/storage-schemas.conf would for whisper. But Influxdb currently has no way to supply us this information (yet), so we must configure it explicitly here. Also, it seems like internally, the graphite-web/graphite-api is to configure the step (resolution in seconds) per metric (i.e. per Node/Reader), without looking at the timeframe. I don't know how to deal with this yet (TODO), so for now it's one step per pattern, so we don't need to specify retention timeframes. (In fact, in the code we can assume the data exists from now to -infinity, missing data you query for will just show up as nulls anyway)

Using with graphite-api

You need the patched version from https://github.com/Dieterbe/graphite-api/tarball/support-templates2 This adds support for caching, statsd instrumentation, and graphite-style templates

In your graphite-api config file:

finders:
  - graphite_influxdb.InfluxdbFinder
influxdb:
   host: localhost
   port: 8086
   user: graphite
   pass: graphite
   db:   graphite
   ssl: false
   schema:
     - ['', [['', 30, '24h'], ['5m_', 300, '30d']]]
     - ['high-res-metrics', [['', 10, '6h'], ['60s_', 60, '24h']]]

Also enable the cache. memcache doesn't seem to work well because the list of series is too big. filesystem seems to work well:

cache:
    type: 'filesystem'
    dir: '/tmp/graphite-api-cache'

Using with graphite-web

In graphite's local_settings.py:

STORAGE_FINDERS = (
    'graphite_influxdb.InfluxdbFinder',
)
INFLUXDB_HOST = "localhost"
INFLUXDB_PORT = 8086
INFLUXDB_USER = "graphite"
INFLUXDB_PASS = "graphite"
INFLUXDB_DB =  "graphite"
INFLUXDB_SSL = "false"
INFLUXDB_SCHEMA = [
    ('', [['', 30, '24h'], ['5m_', 300, '30d']]),
    ('high-res-metrics', [['', 10, '6h'], ['60s_', 60, '24h']])
]
