L7mp stunner監控
Why
有人搞了一個webRTC for k8s用的即時媒體串流方案，
然後我要來接監控了。
L7mp
Solution
參考文件
- 加
enableMetricsEndpoint參數加到Dataplane裡面
...
spec:
args:
- '-w'
- '--udp-thread-num=16'
command:
- stunnerd
enableMetricsEndpoint: true
hostNetwork: false
image: docker.io/l7mp/stunnerd:0.18.0
imagePullPolicy: Always
replicas: 1
resources:
limits:
cpu: 2
memory: 512Mi
requests:
cpu: 500m
memory: 128Mi
terminationGracePeriodSeconds: 3600
- 弄個暫時的pod測試看看metrics有沒有資料
kubectl run alpine-pod -n istio-system --image=alpine --restart=Never -- /bin/sleep 600
先取得stunner的pod ip，再來就看有沒有資料了
curl http://192.168.1.25:8080/metrics
有資料後再來下一步。
這邊要注意一下，剛開後，stunner開頭的指標通通找不到，
像是stunner_listener_connections_total、stunner_listener_bytes_total...等。
我放了一陣子(一兩個小時？)，就突然跑出來了，
我不確定為什麼，等之後再測試看看。
- prometheus 設定 discover
詳細說明，參考209. k8s中srs的各個pod metrics取得
scrape_configs:
- job_name: 'ome'
scrape_interval: 10s
kubernetes_sd_configs:
- role: pod
relabel_configs:
- source_labels: [__meta_kubernetes_pod_name]
action: keep
regex: tcp-gateway.*
- source_labels: [__meta_kubernetes_pod_container_port_name]
action: replace
target_label: portname
replacement: 8080
- 建立Grafana
