Network Monitoring

Cloud provider network networking

Each cloud provider has some preconfigured service to monitor networking such as Amazon CloudWatch, Google operations suite and Azure Monitor.

Linkerd Viz

Linkerd comes with an optional dashboard solution known as Linkerd Viz. It is not installed by default due to the non-negligible resource requirement (it installs Prometheus and Grafana as well as a few smaller tools), but can be easily added with the following commands:

curl -fsL https://run.linkerd.io/install | sh   # Install linkerd CLI
linkerd viz install | kubectl apply -f -        # Install linkerd monitoring stack
linkerd viz dashboard                           # open the dashboard
