# InfluxDB Output Plugin
This plugin writes to [InfluxDB](https://www.influxdb.com) via HTTP or UDP.
2016-08-09 06:50:35 +00:00
### Configuration:
```toml
# Configuration for influxdb server to send metrics to
[[outputs.influxdb]]
## The HTTP or UDP URL for your InfluxDB instance. Each item should be
## of the form:
## scheme "://" host [ ":" port]
##
2016-08-09 06:50:35 +00:00
## Multiple urls can be specified as part of the same cluster,
## this means that only ONE of the urls will be written to each interval.
# urls = ["udp://localhost:8089"] # UDP endpoint example
urls = ["http://localhost:8086"] # required
## The target database for metrics (telegraf will create it if not exists).
database = "telegraf" # required
## Name of existing retention policy to write to. Empty string writes to
## the default retention policy.
2016-08-09 06:50:35 +00:00
retention_policy = ""
## Write consistency (clusters only), can be: "any", "one", "quorum", "all"
2016-08-09 06:50:35 +00:00
write_consistency = "any"
## Write timeout (for the InfluxDB client), formatted as a string.
## If not provided, will default to 5s. 0s means no timeout (not recommended).
timeout = "5s"
# username = "telegraf"
# password = "metricsmetricsmetricsmetrics"
## Set the user agent for HTTP POSTs (can be useful for log differentiation)
# user_agent = "telegraf"
## Set UDP payload size, defaults to InfluxDB UDP Client default (512 bytes)
# udp_payload = 512
## Optional SSL Config
# ssl_ca = "/etc/telegraf/ca.pem"
# ssl_cert = "/etc/telegraf/cert.pem"
# ssl_key = "/etc/telegraf/key.pem"
## Use SSL but skip chain & host verification
# insecure_skip_verify = false
## HTTP Proxy Config
# http_proxy = "http://corporate.proxy:3128"
## Optional HTTP headers
# http_headers = {"X-Special-Header" = "Special-Value"}
## Compress each HTTP request payload using GZIP.
# content_encoding = "gzip"

### Required parameters:
* `urls`: List of strings, this is for InfluxDB clustering
support. On each flush interval, Telegraf will randomly choose one of the urls
to write to. Each URL should start with either `http://` or `udp://`
* `database`: The name of the database to write to.
### Optional parameters:
* `write_consistency`: Write consistency (clusters only), can be: "any", "one", "quorum", "all".
* `retention_policy`: Name of existing retention policy to write to. Empty string writes to the default retention policy.
* `timeout`: Write timeout (for the InfluxDB client), formatted as a string. If not provided, will default to 5s. 0s means no timeout (not recommended).
* `username`: Username for influxdb
* `password`: Password for influxdb
* `user_agent`: Set the user agent for HTTP POSTs (can be useful for log differentiation)
* `udp_payload`: Set UDP payload size, defaults to InfluxDB UDP Client default (512 bytes)
* `ssl_ca`: SSL CA
* `ssl_cert`: SSL CERT
* `ssl_key`: SSL key
* `insecure_skip_verify`: Use SSL but skip chain & host verification (default: false)
* `http_proxy`: HTTP Proxy URI
* `http_headers`: HTTP headers to add to each HTTP request
* `content_encoding`: Compress each HTTP request payload using gzip if set to: "gzip"
