# influxdb plugin
|
|
|
|
The InfluxDB plugin will collect metrics on the given InfluxDB servers.
|
|
|
|
This plugin can also gather metrics from endpoints that expose
|
|
InfluxDB-formatted endpoints. See below for more information.
|
|
|
|
### Configuration:
|
|
|
|
```toml
|
|
# 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"
|
|
]
|
|
|
|
## 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"
|
|
```
|
|
|
|
### Measurements & Fields
|
|
|
|
**Note:** The measurements and fields are dynamically built from the InfluxDB source,
|
|
and may vary between versions.

### 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
|
|
[[inputs.influxdb]]
|
|
urls = [
|
|
"http://127.0.0.1:8086/debug/vars",
|
|
"http://192.168.2.1:8086/debug/vars"
|
|
]
|
|
```
