# InfluxDB Input Plugin

The InfluxDB plugin will collect metrics on the given InfluxDB servers. Read our
[documentation](https://docs.influxdata.com/platform/monitoring/influxdata-platform/tools/measurements-internal/)
for detailed information about `influxdb` metrics.

This plugin can also gather metrics from endpoints that expose
InfluxDB-formatted endpoints. See below for more information.

## Configuration

```toml @sample.conf
# Read InfluxDB-formatted JSON metrics from one or more HTTP endpoints
[[inputs.influxdb]]
  ## Works with InfluxDB debug endpoints out of the box,
  ## but other services can use this format too.
  ## See the influxdb plugin's README for more details.

  ## Multiple URLs from which to read InfluxDB-formatted JSON
  ## Default is "http://localhost:8086/debug/vars".
  urls = [
    "http://localhost:8086/debug/vars"
  ]

  ## Username and password to send using HTTP Basic Authentication.
  # username = ""
  # password = ""

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## http request & header timeout
  timeout = "5s"
```

## InfluxDB-formatted endpoints

The influxdb plugin can collect InfluxDB-formatted data from JSON endpoints.
Whether associated with an Influx database or not.

With a configuration of:

```toml
