# `finallycoffee.observability.cadvisor` ansible role
|
|
|
|
## Overview
|
|
|
|
Deploys [cadvisor](https://github.com/google/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
|
|
```yaml
|
|
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.
