### Enabling Metric Collection
|
|
|
|
1. To enable prometheus metrics collection you will want to update `config-observability` ConfigMap and set the `metrics-protocol` to `prometheus`. For request-metrics we recommend setting up pushing metrics to prometheus. This requires enabling the Prometheus OLTP receiver. This is already configured in our monitoring example.
|
|
|
|
|
|
```yaml
|
|
apiVersion: v1
|
|
kind: ConfigMap
|
|
metadata:
|
|
name: config-observability
|
|
namespace: knative-serving
|
|
data:
|
|
# metrics-protocol field specifies the protocol used when exporting metrics
|
|
# It supports either 'none' (the default), 'prometheus', 'http/protobuf' (OTLP HTTP), 'grpc' (OTLP gRPC)
|
|
metrics-protocol: prometheus
|
|
|
|
# request-metrics-protocol
|
|
request-metrics-protocol: http/protobuf
|
|
request-metrics-endpoint: http://knative-kube-prometheus-st-prometheus.observability.svc:9090/api/v1/otlp/v1/metrics
|
|
|
|
tracing-protocol: http/protobuf
|
|
tracing-endpoint: http://jaeger-collector.observability.svc:4318/v1/traces
|
|
tracing-sampling-rate: "1"
|
|
|
|
```
|
|
|
|
1. Apply the ServiceMonitors/PodMonitors to collect metrics from Knative Serving Control Plane.
|
|
|
|
```bash
|
|
kubectl apply -f https://raw.githubusercontent.com/knative-extensions/monitoring/main/config/serving-monitors.yaml
|
|
```
|
|
|
|
### Import Grafana dashboards
|
|
|
|
1. Grafana dashboards can be imported from the [`monitoring` repository](https://github.com/knative-extensions/monitoring).
|
|
|
|
1. If you are using the Grafana Helm Chart with the dashboard sidecar enabled (the default), you can load the dashboards by applying the following configmaps.
|
|
|
|
```bash
|
|
kubectl apply -f https://raw.githubusercontent.com/knative-extensions/monitoring/main/config/configmap-serving-dashboard.yaml
|
|
```
