# Telegraf Input Plugin: Consul
|
|
|
|
This plugin will collect statistics about all helath checks registered in the Consul. It uses [Consul API](https://www.consul.io/docs/agent/http/health.html#health_state)
|
|
to query the data. It will not report the [telemetry](https://www.consul.io/docs/agent/telemetry.html) but Consul can report those stats already using StatsD protocol if needed.
|
|
|
|
## Configuration:
|
|
|
|
```
|
|
# Gather health check statuses from services registered in Consul
|
|
[[inputs.consul]]
|
|
## Most of these values defaults to the one configured on a Consul's agent level.
|
|
## Optional Consul server address (default: "")
|
|
# address = ""
|
|
## Optional URI scheme for the Consul server (default: "")
|
|
# scheme = ""

|
## Optional ACL token used in every request (default: "")
|
|
# token = ""
|
|
## Optional username used for request HTTP Basic Authentication (default: "")
|
|
# username = ""
|
|
## Optional password used for HTTP Basic Authentication (default: "")
|
|
# password = ""
|
