Getting Started

Installing via helm

helm version 3

1. kubectl create namespace zebrium
2. If node-exporter has not been installed, install it first:

     helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
     helm repo update
     helm install node-exporter --namespace zebrium prometheus-community/prometheus-node-exporter
   

3. helm install zstats-collector zstats --namespace zebrium --repo https://raw.githubusercontent.com/zebrium/ze-stats/master/charts --set zebrium.collectorUrl=YOUR_ZE_STATS_API_URL,zebrium.authToken=YOUR_ZE_API_AUTH_TOKEN,zebrium.deployment=YOUR_DEPLOYMENT_NAME

Please note TCP port 9100 must be accessible from other kubernetes nodes in the same cluster.

helm version 2

1. If node-exporter has not been installed, install it first:

     helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
     helm repo update
     helm install --namespace zebrium --name node-exporter prometheus-community/prometheus-node-exporter
   

2. helm install --namespace zebrium --name zstats-collector --repo https://raw.githubusercontent.com/zebrium/ze-stats/master/charts zstats --set zebrium.collectorUrl=YOUR_ZE_STATS_API_URL,zebrium.authToken=YOUR_ZE_API_AUTH_TOKEN,zebrium.deployment=YOUR_DEPLOYMENT_NAME
