# Kapacitor Plugin
|
||||||
|
|
||||||
|
The Kapacitor plugin will collect metrics from the given Kapacitor instances.
|
||||||
|
|
||||||
|
### Configuration:
|
||||||
|
|
||||||
|
```toml
|
||||||
|
[[inputs.kapacitor]]
|
||||||
|
## Multiple URLs from which to read Kapacitor-formatted JSON
|
||||||
|
## Default is "http://localhost:9092/kapacitor/v1/debug/vars".
|
||||||
|
urls = [
|
||||||
|
"http://localhost:9092/kapacitor/v1/debug/vars"
|
||||||
|
]
|
||||||
|
|
||||||
|
## Time limit for http requests
|
||||||
|
timeout = "5s"
|
||||||
|
```
|
||||||
|
|
||||||
