| # Configs API | ||
|
|
||
| The configs service provides an API-driven multi-tenant approach to handling various configuration files for prometheus. The service hosts an API where users can read and write Prometheus rule files, Alertmanager configuration files, and Alertmanager templates to a database. | ||
|
|
||
| Each tenant will have it's own set of rule files, Alertmanager config, and templates. A POST operation will effectively replace the existing copy with the configs provided in the request body. | ||
|
|
||
| ## Configs Format | ||
|
|
||
| At the current time of writing, the API is part-way through a migration from a single Configs service that handled all three sets of data to a split API ([Tracking issue](https://github.com/cortexproject/cortex/issues/619)). All APIs take and return all sets of data. | ||
|
|
||
| The following schema is used both when retrieving the current configs from the API and when setting new configs via the API. | ||
|
|
||
| ### Schema: | ||
|
|
||
| ```json | ||
| { | ||
| "id": 99, | ||
| "rule_format_version": "2", | ||
| "config": { | ||
| "alertmanager_config": "<standard alertmanager.yaml config>", | ||
| "rules_files": { | ||
| "rules.yaml": "<standard rules.yaml config>", | ||
| "rules2.yaml": "<standard rules.yaml config>" | ||
| }, | ||
| "template_files": { | ||
| "templates.tmpl": "<standard template file>", | ||
| "templates2.tmpl": "<standard template file>" | ||
| } | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| ### Formatting | ||
|
|
||
| `id` - should be incremented every time data is updated; Cortex will use the config with the highest number. | ||
|
|
||
| `rule_format_version` - allows compatibility for tenants with config in Prometheus V1 format. Pass "1" or "2" according to which Prometheus version you want to match. | ||
|
|
||
| `config.alertmanager_config` - The contents of the alertmanager config file should be as described [here](https://prometheus.io/docs/prometheus/latest/configuration/alerting_rules/), encoded as a single string to fit within the overall JSON payload. | ||
|
|
||
| `config.rules_files` - The contents of a rules file should be as described [here](http://prometheus.io/docs/prometheus/latest/configuration/recording_rules/), encoded as a single string to fit within the overall JSON payload. | ||
|
|
||
| `config.template_files` - The contents of a template file should be as described [here](https://prometheus.io/docs/alerting/notification_examples/#defining-reusable-templates), encoded as a single string to fit within the overall JSON payload. | ||
|
|
||
| ## Endpoints | ||
|
|
||
| ### Manage Alertmanager | ||

|
|
||
| Normal Response: OK(200) | ||
| ```json | ||
| { | ||
| "status": "success" | ||
| } | ||
| ``` | ||
|

| - Normal Response Codes: OK(200) | ||
| - Error Response Codes: Unauthorized(400), NotFound(404) | ||
|
|
||
| `POST /api/prom/configs/rules` - Replace current rule files | ||
|
|
||
| - Normal Response Codes: NoContent(204) | ||
| - Error Response Codes: Unauthorized(401), BadRequest(400) | ||
|
|
||
| ### Manage Templates | ||

| - Error Response Codes: Unauthorized(401), NotFound(404) | ||
|
|
||
| `POST /api/prom/configs/templates` - Replace current templates | ||

|
|
||
| ### Deactivate/Restore Configs | ||
|
|
||
| `DELETE /api/prom/configs/deactivate` - Disable configs for a tenant | ||
|
|
||
| - Normal Response Codes: OK(200) | ||
| - Error Response Codes: Unauthorized(401), NotFound(404) | ||
|
|
||
| `POST /api/prom/configs/restore` - Re-enable configs for a tenant | ||
|
|
||
| - Normal Response Codes OK(200) | ||
| - Error Response Codes: Unauthorized(401), NotFound(404) | ||
|
|
||
| These API endpoints will disable/enable the current Rule and Alertmanager configuration for a tenant. | ||
|
|
||
| Note that setting a new config will effectively "re-enable" the Rules and Alertmanager configuration for a tenant. |
