This repository contains helm charts for the PROM stack which includes:

prometheus-node-exporter
prometheus-server
alertmanager
grafana

The helm charts are from https://github.com/helm/charts/tree/master/stable

To install portworx:

https://docs.portworx.com/portworx-install-with-kubernetes/

After installing portworx, create a storageClass to be used

kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
  name: px-high-rf2
provisioner: kubernetes.io/portworx-volume
parameters:
  fs: "ext4"
  block_size: "4k"
  shared: "false"
  repl: "2"
  snap_interval:   "0"
  priority_io:  "high"

To install the chart:

git clone https://github.com/satchpx/prom-helm.git
cd prom-helm/
helm install --name prometheus --namespace monitoring prometheus --set server.persistentVolume.storageClass=<portworx-storageClassName>,server.shedulerName=stork
helm install --name grafana --namespace monitoring grafana --set persistence.enabled=true,persistence.storageClassName=<portworx-storageClassName>,schedulerName=stork

The above is configured already to add prometheus as the datasource for grafana.

To login to grafana:

1. NOTE: The chart generates a random password for the admin user. To specify your own, either update values.yaml or set is in the helm install command using --set adminPassword=<myStrongPassword>. Alternatively, you can also reference a kubernetes secret containing the password key using --set admin.passwordKey=<secretName>

Otherwise, to access grafana UI without any of the above, get the random password using:

kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

2. The Grafana server can be accessed via port 80 on the following DNS name from within your cluster: grafana.monitoring.svc.cluster.local

   Get the Grafana URL to visit by running these commands in the same shell:

  export POD_NAME=$(kubectl get pods --namespace monitoring -l "app=grafana,release=grafana" -o jsonpath="{.items[0].metadata.name}")
  kubectl --namespace monitoring port-forward $POD_NAME 3000

3. Login with the password from step 1 and the username: admin
