# Kubernetes Input Plugin
|
|
|
|
The Kubernetes plugin can gather metrics from Kubernetes services
|
|
- APIServer
|
|
- Scheduler
|
|
- Controller Manager
|
|
- Kubelet
|
|
|
|
### Configuration:
|
|
|
|
```toml
|
|
# Get metrics from Kubernetes services
|
|
[[inputs.kubernetes.apiserver]]
|
|
url = "http://mtl-nvcbladea-15.nuance.com:8080"
|
|
endpoint = "/metrics"
|
|
timeout = 5.0
|
|
# includes only metrics which match one of the
|
|
# following regexp
|
|
includes = ["apiserver_.*"]
|
|
|
|
[[inputs.kubernetes.scheduler]]
|
|
url = "http://mtl-nvcbladea-15.nuance.com:10251"
|
|
endpoint = "/metrics"
|
|
timeout = 1.0
|
|
# DO NOT include metrics which match one of the
|
|
# following regexp
|
|
excludes = ["scheduler_.*"]
|
|
|
|
[[inputs.kubernetes.controllermanager]]
|
|
url = "http://mtl-nvcbladea-15.nuance.com:10252"
|
|
|
|
[[inputs.kubernetes.kubelet]]
|
|
url = "http://mtl-nvcbladea-15.nuance.com:4194"
|
|
# You should increase metric_buffer_limit
|
|
# Because of number of kubelet metrics
|
|
# otherwise you can limit metrics with
|
|
# the following 'excludes' argument
|
|
excludes = ["container_.*"]
|
|
```
