What is this feature?
Allows the creation of alert rules with mimirtool in a specified folder.
Why do we need this feature?
Currently, the APIs for mimirtool create namespaces and rule groups in the root folder without the ability to set a custom folder. For example, it could be a special "Imported" folder, etc.
This PR makes it possible with a special header: mimirtool ... --extra-headers="X-Grafana-Alerting-Folder-UID=123". If it's not present, the root folder is used, otherwise, the specified one is used.
mimirtool does not support nested folder structures, while Grafana allows folder nesting. To keep compatibility, we return only direct child folders of the working folder (as namespaces) with rule groups and rules that are directly in these child folders as if there are no nested folders.
For example, given this folder structure in Grafana:
```
grafana/
├── production/
│ ├── service1/
│ │ └── alerts/
│ └── service2/
└── testing/
└── service3/
```
If the working folder is "grafana":
Only namespaces "production" and "testing" are returned
Only rule groups directly within these folders are included
If the working folder is "production":
- Only namespaces "service1" and "service2" are returned
Only rule groups directly within these folders are included
Expand template testing to try additional scopes if the root scope fails.
This mitigates errors for definitions like pagerduty.default.instances,
which require the .Alerts scope. Added support for .Alerts and .Alert
scopes.
* add column guid to alert rule table and rule_guid to rule version table
+ populate the new field with UUID
* update storage and domain models
* patch GUID
* ignore GUID in fingerprint tests
Initially, Metadata had only the EditorSettings, and HasMetadata was used to understand if the incoming update request had metadata in the body because it could be omitted if it was empty. For example, when the rule is updated via the provisioning API or has only false values. If it was in the request, we used that; if not, we used the metadata from the existing rule from the database. If the rule was updated via the AlertRuleService, we didn't change Metadata at all if the rule already existed.
But now, Metadata also has the Prometheus rule definition, and we always need to update it with the new version of the AlertRuleService when the rule exists in the DB and has the same UID. HasMetadata is renamed to HasEditorSettings to keep the old behaviour only for EditorSettings.
Now, the provisioning API and the conversion API will overwrite everything except EditorSettings with the new data.
When you use a math expression with out any operators, the dataFrame pointer is identical between the expression result and the input query/expression.
This was resulting in the values returned from an evaluation overshadowing each other, depending on the order of the processing of the result map.
For example:
```
A: some_metric
B: reduce of A
C: math expression -> "${B}"
D: Threshold evaluation of C -> "C > 0"
```
With a value of 1 for `some_metric`, might result in a evaluation result of one of the following (somewhat at random):
1. { B: 1, D: 1 }
2. { C: 1, D: 1}
While you would expect to see:
{ B: 1, C: 1, D: 1 }
update scheduler's aler rule to accept regular Evaluation in update channel
This makes it accept the full rule definition, which is required in reset state.
What is this feature?
Adds an API endpoint to create alert rules with mimirtool:
- POST /convert/prometheus/config/v1/rules/{NamespaceTitle} - Accepts a single rule group in a Prometheus YAML format and creates or updates a Grafana rule group from it.
The endpoint uses the conversion package from #100224.
Key parts
The API works similarly to the provisioning API. If the rule does not exist, it will be created, otherwise updated. Any rules not present in the new group will be deleted, ensuring the group is fully synchronized with the provided configuration.
Since the API works with namespace titles (folders), the handler automatically creates a folder in the root based on the provided title if it does not exist. It also requires a special header, X-Grafana-Alerting-Datasource-UID. This header specifies which datasource to use for the new rules.
If the rule group's evaluation interval is not specified, it uses the DefaultRuleEvaluationInterval from settings.
* Send new annotation containing image url
* Use new image TokenProvider with TokenStore
New abstraction GetImage no longer needs to support parsing both token and
url from annotations, as remote AM will use the new URLProvider. Instead, we
use the new generic TokenProvider and give it a TokenStore backed by the
grafana database.
That means we revert back to always using token simplifying code and security
considerations.
* Upgrade grafana/alerting to merged commit SHA
* split create to create and patch and move to state
patch will be refactored further
* move setNextState to state transition
* move tests
* split tests for patch function
* Alerting: Call RLock() before reading sendAlertsTo map
* defer unlocking
* drive-tru fix for another lock
* less time holding the lock in SyncAndApplyConfigFromDatabase
* Alerting: Fix Alertmanager configuration updates
Alertmanager configuration updates would behave inconsistently when performing no-op updates with `mysql` as the store.
In particular this bug manifested as a failure to reload the provisioned alertmanager configuration components with no changes to the configuration itself. This would result in a 500 error with mysql store only.
The core issue is that we were relying on the number of rows affected by the update query to determine if the configuration was found in the db or not.
While this behavior works for certain sql dialects, mysql does not return the number of rows matched by the update query but rather the number of rows actually updated.
Also discovered and fixed the mismatched `xorm` tag for the `CreatedAt` field to match the actual column name in the db.
