# Consul Input Plugin
|
|
|
|
This plugin will collect statistics about all health 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:
|
|
|
|
```toml
|
|
# Gather health check statuses from services registered in Consul
|
|
[[inputs.consul]]
|
|
## Consul server address
|
|
# address = "localhost:8500"
|
|
|
|
## URI scheme for the Consul server, one of "http", "https"
|
|
# scheme = "http"
|
|
|
|
## ACL token used in every request
|
|
# token = ""
|
|
|
|
## HTTP Basic Authentication username and password.
|
|
# username = ""
|
|
# password = ""
|
|
|
|
## Data center to query the health checks from
|
|
# datacenter = ""
|
|
|
|
## 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 = true
|
|
|
|
## Consul checks' tag splitting
|
|
# When tags are formatted like "key:value" with ":" as a delimiter then
|
|
# they will be splitted and reported as proper key:value in Telegraf
|
|
# tag_delimiter = ":"
|
|
```
|
|
|
|
### Metrics:
|
|
|
|
- consul_health_checks
|
|
- tags:
|
|
- node (node that check/service is registered on)
|
|
- service_name
|
|
- check_id
|
|
- fields:
|
|
- check_name
|
|
- service_id
|
|
- status
|
|
- passing (integer)
|
|
- critical (integer)
|
|
- warning (integer)
|
|
|
|
`passing`, `critical`, and `warning` are integer representations of the health
|
|
check state. A value of `1` represents that the status was the state of the
|
|
the health check at this sample.
|
|
|
|
