If you have an existing Prometheus cluster, it is very easy to export Conduit's
|
|
rich telemetry data to your cluster. Simply add the following item to your
|
|
`scrape_configs` in your Prometheus config file:
|
|
|
|
```yaml
|
|
- job_name: 'conduit-controller'
|
|
kubernetes_sd_configs:
|
|
- role: pod
|
|
namespaces:
|
|
names: ['{{.Namespace}}']
|
|
relabel_configs:
|
|
- source_labels:
|
|
- __meta_kubernetes_pod_label_conduit_io_control_plane_component
|
|
- __meta_kubernetes_pod_container_port_name
|
|
action: keep
|
|
regex: (.*);admin-http$
|
|
- source_labels: [__meta_kubernetes_pod_container_name]
|
|
action: replace
|
|
target_label: component
|
|
|
|
- job_name: 'conduit-proxy'
|
|
kubernetes_sd_configs:
|
|
- role: pod
|
|
relabel_configs:
|
|
- source_labels:
|
|
- __meta_kubernetes_pod_container_name
|
|
- __meta_kubernetes_pod_container_port_name
|
|
action: keep
|
|
regex: ^conduit-proxy;conduit-metrics$
|
|
- source_labels: [__meta_kubernetes_namespace]
|
|
action: replace
|
|
target_label: namespace
|
|
# __meta_kubernetes_pod_label_conduit_io_proxy_deployment=foo =>
|
|
# k8s_deployment=foo
|
|
- action: labelmap
|
|
regex: __meta_kubernetes_pod_label_conduit_io_proxy_(.+)
|
|
replacement: k8s_$1
|
|
# drop all labels that we just made copies of in the previous labelmap
|
|
- action: labeldrop
|
|
regex: __meta_kubernetes_pod_label_conduit_io_proxy_(.+)
|
|
# __meta_kubernetes_pod_label_foo=bar => k8s_foo=bar
|
|
- action: labelmap
|
|
regex: __meta_kubernetes_pod_label_(.+)
|
|
replacement: k8s_$1
|
|
```
|
|
|
|
That's it! Your Prometheus cluster is now configured to scrape Conduit's
|
|
metrics.
|
|
|
|
Conduit's proxy metrics will have the label `job="conduit-proxy"`. Conduit's
|
|
control-plane metrics will have the label `job="conduit-controller"`.
|
|
|
