cadvisor

cAdvisor sandbox

In this sandbox, cAdvisor gathers metrics for three running containers:

• Its own container
• A container running Redis
• A container running Prometheus

The Prometheus instance scrapes metrics from cAdvisor and makes them accessible via the Prometheus expression browser.

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 the three containers mentioned above.

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

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

• rate(container_cpu_usage_seconds_total{name="redis"}[1m])
• container_memory_usage_bytes{name="redis"}
• rate(container_network_transmit_bytes_total[1m])
• rate(container_network_receive_bytes_total[1m])
