Deployment¶

sb install prometheus

Usage¶

Visit https://prometheus.iYOUR_DOMAIN_NAMEi.

Basics¶

Prometheus provides monitoring and alerting with automatic installation of Node Exporter and cAdvisor for system and container metrics. Configuration is at /opt/prometheus/prometheus.yml. Data retention defaults to 15 days but can be configured in your Saltbox inventory using prometheus_role_retention and prometheus_role_size.

Add custom scrape targets to the config file and restart with docker restart prometheus. Works excellently with Grafana using data source http://prometheus:9090.

Role Defaults¶

Use the Inventory to customize variables. (1)

Example override
```
prometheus_name: "custom_value"
```
Avoid overriding variables ending in _default

When overriding variables that end in _default (like prometheus_docker_envs_default), you replace the entire default configuration. Future updates that add new default values will not be applied to your setup, potentially breaking functionality.

Instead, use the corresponding _custom variable (like prometheus_docker_envs_custom) to add your changes. Custom values are merged with defaults, ensuring you receive updates.
