node-exporter

Node Exporter sandbox

In this sandbox, Prometheus scrapes Linux host metrics from a Node Exporter.

Usage

To start the sandbox:

# In the foreground
make run # docker-compose up --build

# In detached mode
make run-detached # docker-compose up --build --detach

This will start up a node_exporter container and a prometheus container.

To kill the sandbox, run make kill (alias for docker-compose kill).

Open up http://localhost:9090/graph to access the Prometheus expression browser. Here are some example metrics to explore:

• rate(node_cpu_seconds_total{mode="system"}[1m])
• node_filesystem_avail_bytes
• rate(node_network_receive_bytes_total[1m])
