Lightweight Prometheus exporter for Linux containers/cgroups.
Container Exporter collects metrics from within a Linux container. Useful to scrape container metrics without read access to host metrics. If you have host access or at least to its metrics, you should consider cadvisor instead.
Copy, chmod +x and run
container-exporter
as a daemon before start the main process. The default listening
port is 9009, change the default port with the optional -b :8000
command-line argument.
The following metrics are available:
| Name | Description |
|---|---|
container_memory_usage_bytes |
Current memory usage in bytes |
container_cpu_usage_seconds_total |
Cumulative CPU time consumed in seconds |
container_network_transmit_bytes_total |
Cumulative count of bytes transmitted |
container_network_receive_bytes_total |
Cumulative count of bytes received |
CPU and network metrics are counters and might be used with
rate()
to calculate per-second average rate.
