finallycoffee.observability.cadvisor ansible role
Overview
Deploys cadvisor, a daemon for collecting and exporting information about running (docker) containers in a docker container.
Configuration
In order to scrape /metrics of running containers, it is recommended
to expose the default port of cadvisor to the host using
cadvisor_container_ports:
- "127.0.0.1:8080:8080`
so that cadvisor metrics are exposed at http://127.0.0.1:8080/metrics.
Enabling/Disabling collection of metrics
By setting cadvisor_disabled_metrics, the collection of metrics
can be disabled. The default list of disabled metrics is quite extensive,
so when enabling a disabled-by-default metric, it is recommended to
use cadvisor_force_enable_metrics instead, as it's empty by default.
