Kubernetes metrics

Note: This page describes the newly-released version 1.x of the Kubernetes integration. If you're running the Automated dashboard-based version, see our Kubernetes 0.x documentation.

The AppSignal for Kubernetes integration extracts metrics from Kubernetes clusters.

After adding the AppSignal Kubernetes deployment to your cluster, a Cluster Metrics page appears in AppSignal, showing per-node and per-pod metrics.

Installation

To start reporting Kubernetes cluster metrics to AppSignal:

  1. Store your AppSignal API key in a secret
  2. Add AppSignal deployment to your cluster

1. Store your AppSignal API key in a secret

In a Kubernetes cluster, set up your AppSignal API key (find your App-specific API key in App settings) by creating a secret:

Shell
kubectl create secret generic appsignal --from-literal=api-key=<APPSIGNAL_API_KEY>

2. Add AppSignal deployment to your cluster

Once you've created the AppSignal API key secret, add the AppSignal deployment to your cluster:

Shell
kubectl apply -f https://raw.githubusercontent.com/appsignal/appsignal-kubernetes/main/deployment.yaml

Alternatively, install AppSignal through its Helm chart:

Shell
helm repo add appsignal-kubernetes https://appsignal.github.io/appsignal-kubernetes
helm install appsignal-kubernetes/appsignal-kubernetes --generate-name

Once configured, AppSignal for Kubernetes will start reporting Kubernetes metrics automatically.

Cluster Metrics

In AppSignal, the Host Metrics page will now be replaced with a Cluster Metrics page to show information about pods and nodes in your cluster. You will be able to see graphs representing useful metrics over time, such as:

  • CPU Usage: CPU usage stats per node or pod
  • Memory Usage: memory usage statistics, comparing the used memory to what's available per node or pod
  • Swap Usage: swap usage statistics, comparing the used swap to what's available per node or pod
  • Disk Usage: disk usage statistics, comparing the used disk space to what's available per node
  • Network usage: network usage, split by received and transmitted bytes, per node
