Influxdb backend plugin for graphite-web and graphite-api
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)
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/brutasse/graphite-api/pull/36 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 schema: - ['', 60] - ['high-res-metrics', 10]
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: CACHE_TYPE: 'filesystem' CACHE_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_SCHEMA = [ ('', 60), ('high-res-metrics', 10) ]
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
