* Add FiredAt field to the State
* Update featuretoggle files
* Fix lint errors
* Fix test compilation
* Remove random print line + formatting
* Address PR comments
* 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
* Simple replace of State.Resolved with State.ResolvedAt
* Retain ResolvedAt time between Normal->Normal transition
* Introduce ResolvedRetention to keep sending recently resolved alerts
* Make ResolvedRetention configurable with resolved_alert_retention
* Tick-based LastSentAt for testing of ResendDelay and ResolvedRetention
* Do not reset ResolvedAt during Normal->Pending transition
Initially this was done to be inline with Prom ruler. However, Prom ruler
doesn't keep track of Inactive->Pending/Alerting using the same alert instance,
so it's more understandable that they choose not to retain ResolvedAt. In our
case, since we use the same cached instance to represent the transition, it
makes more sense to retain it.
This should help alleviate some odd situations where temporarily entering
Pending will stop future resolved notifications that would have happened
because of ResolvedRetention.
* Pointers for ResolvedAt & LastSentAt
To avoid awkward time.Time{}.Unix() defaults on persist
* Alerting: Fix NoData & Error alerts not resolving when rule is reset
On rule reset, when creating the PostableAlerts StateToPostableAlert did not
attach the correct NoData/Error alertname and rulename labels to expire/resolve
the active alerts when the previous cached state was NoData/Error.
* Alerting: Repurpose rule testing endpoint to return potential alerts
This feature replaces the existing no-longer in-use grafana ruler testing API endpoint /api/v1/rule/test/grafana. The new endpoint returns a list of potential alerts created by the given alert rule, including built-in + interpolated labels and annotations.
The key priority of this endpoint is that it is intended to be as true as possible to what would be generated by the ruler except that the resulting alerts are not filtered to only Resolved / Firing and ready to be sent.
This means that the endpoint will, among other things:
- Attach static annotations and labels from the rule configuration to the alert instances.
- Attach dynamic annotations from the datasource to the alert instances.
- Attach built-in labels and annotations created by the Grafana Ruler (such as alertname and grafana_folder) to the alert instances.
- Interpolate templated annotations / labels and accept allowed template functions.
