Metrics for JVM

[munsayac13]

Installed custom metric but I do not see all the metrics I need specially for JVM metrics. In addition, it appears the image does not like using custom config.yaml. Below I created adapter-config configmap specifically for JVM.

apiVersion: v1
kind: ConfigMap
metadata:
  name: adapter-config
  namespace: monitoring
data:
  config.yaml: |
    - seriesQuery: '{__name__=~"jvm_.*",kubernetes_name!="",kubernetes_namespace!=""}'
      resources:
        overrides:
          kubernetes_namespace:
            resource: namespace
          kubernetes_name:
            resource: pod
      name:
        matches: "^jvm_(.*)"
      metricsQuery: sum(<<.Series>>{<<.LabelMatchers>>}) by (<<.GroupBy>>)

However, when I use the config in deployment.yaml, the pod crashes pointing that it does not recognize the flag.

    spec:
      serviceAccountName: custom-metrics-apiserver
      containers:
      - name: custom-metrics-apiserver
        image: quay.io/coreos/k8s-prometheus-adapter-amd64:v0.2.0
        args:
        - /adapter
        - --secure-port=6443
        - --tls-cert-file=/var/run/serving-cert/serving.crt
        - --tls-private-key-file=/var/run/serving-cert/serving.key
        - --logtostderr=true
        - --prometheus-url=http://prometheus.monitoring.svc:9090/
        - --metrics-relist-interval=30s
        - --rate-interval=5m
        - --v=10
        - --config=/etc/adapter/config.yaml

panic: unknown flag: --config

goroutine 1 [running]:
main.main()
        /go/src/github.com/directxman12/k8s-prometheus-adapter/cmd/adapter/adapter.go:41 +0x114

Can you assist on how I can expose jvm metrics to custom.metrics.k8s.io?

Thanks,
