* Alerting: Improve error when receiver used by rule is deleted
* Remove RuleUID from public error and data
* Improve fallback error in am config post
* Refactor to expand to time intervals
* Fix message on unchecked errors to be same as before
* Alerting: Implement SaveAndApplyConfiguration in the forked Alertmanager struct
* call SaveAndApplyConfig on the remote first, log errors for the internal
* add comments explaining why we ignore errors in the internal AM
* restore go.work.sum
This splits the request handlers into two functions, one which is the actual
handler and one which is independent from the Grafana `ReqContext` object. This
is to make it easier to reuse the implementation in other code.
Part of the refactoring changes the functions which get query parameters from
the request to operate on a `url.Values` instead of the request object.
The change also makes the code consistently use `req.Form` instead of a
combination of `req.URL.Query()` and `req.Form`, though I have left
`api_ruler` as-is to avoid this PR growing too large.
* implement SaveAndApplyConfig in the remote Alertmanager struct
* remove ID from CreateGrafanaAlertmanagerConfig call
* decrypt, test that we decrypt, refactor
* fix duplicated declaration in test
* rephrase comment, remove unnecessary conversion to slice of bytes
* fix test
* Alerting: Implement SaveAndApplyDefaultConfig in the forked Alertmanager (remote primary)
* log the error for the internal AM instead of returning it
This test has been skipped for a long time, so it doesn't work anymore. I've
fixed the test so it works again, but left some tests disabled which were
apparently flaky. If we see the other test cases flaking, we'll have to
disable it again.
Fixes:
- Use fake access control for most test cases, and real one for FGAC test cases.
- Check that "file" in API responses the full folder path, not folder title.
* Alerting: Consistently return Prometheus-style responses from rules APIs.
This commit is part refactor and part fix. The /rules API occasionally returns
error responses which are inconsistent with other error responses. This fixes
that, and adds a function to map from Prometheus error type and HTTP code.
* Fix integration tests
* Linter happiness
* Make linter more happy
* Fix up one more place returning non-Prometheus responses
* Alerting: Implement SaveAndApplyDefaultConfig in the remote Alertmanager struct
* send the hash of the encrypted configuration
* tests, default config hash in AM struct
* add missing default config to test
* restore build directory
* go work file...
* fix broken test
* remove unnecessary conversion to []byte
* go work again...
* make things work again with latest main branch changes
* update error messages in tests for decrypting config
Preparing these functions to be used by some other part of the codebase,
which does not have a `contextmodel.ReqContext`, only the normal request
structure (`url.Values`, etc). This is slightly messy because of how
Grafana allows url parameters to be in the URL or in the request body,
so we need to make sure to invoke the form parsing logic in `ReqContext`.
* Alerting: Optimize rule status gathering APIs when a limit is applied.
The frontend very commonly calls the `/rules` API with `limit_alerts=16`. When
there are a very large number of alert instances present, this API is quite
slow to respond, and profiling suggests that a big part of the problem is
sorting the alerts by importance, in order to select the first 16.
This changes the application of the limit to use a more efficient heap-based
top-k algorithm. This maintains a slice of only the highest ranked items whilst
iterating the full set of alert instances, which substantially reduces the
number of comparisons needed. This is particularly effective, as the
`AlertsByImportance` comparison is quite complex.
I've included a benchmark to compare the new TopK function to the existing
Sort/limit strategy. It shows that for small limits, the new approach is
much faster, especially at high numbers of alerts, e.g.
100K alerts / limit 16: 1.91s vs 0.02s (-99%)
For situations where there is no effective limit, sorting is marginally faster,
therefore in the API implementation, if there is either a) no limit or b) no
effective limit, then we just sort the alerts as before. There is also a space
overhead using a heap which would matter for large limits.
* Remove commented test cases
* Make linter happy
* Alerting: Fix simplified routing custom group by override
Custom group by overrides for simplified routing were missing required fields
GroupBy and GroupByAll normally set during upstream Route validation.
This fix ensures those missing fields are applied to the generated routes.
* Inline GroupBy and GroupByAll initialization instead of normalize after
* Alerting: Fix simplified routes '...' groupBy creating invalid routes
There were a few ways to go about this fix:
1. Modifying our copy of upstream validation to allow this
2. Modify our notification settings validation to prevent this
3. Normalize group by on save
4. Normalized group by on generate
Option 4. was chosen as the others have a mix of the following cons:
- Generated routes risk being incompatible with upstream/remote AM
- Awkward FE UX when using '...'
- Rule definition changing after save and potential pitfalls with TF
With option 4. generated routes stay compatible with external/remote AMs, FE
doesn't need to change as we allow mixed '...' and custom label groupBys, and
settings we save to db are the same ones requested.
In addition, it has the slight benefit of allowing us to hide the internal
implementation details of `alertname, grafana_folder` from the user in the
future, since we don't need to send them with every FE or TF request.
* Safer use of DefaultNotificationSettingsGroupBy
* Fix missed API tests
* Alerting: Persist silence state immediately on Create/Delete
Persists the silence state to the kvstore immediately instead of waiting for the
next maintenance run. This is used after Create/Delete to prevent silences from
being lost when a new Alertmanager is started before the state has persisted.
This can happen, for example, in a rolling deployment scenario.
* Fix test that requires real data
* Don't error if silence state persist fails, maintenance will correct
* extract genericService from RuleService just to reuse it later
* implement silence service

Terraform Issue: grafana/terraform-provider-grafana#1007
Nested routes should be allowed to inherit the contact point from the root (or direct parent) route but this fails in the provisioning API (it works in the UI)
* allow users with regular actions access provisioning API paths
* update methods that read rules
skip new authorization logic if user CanReadAllRules to avoid performance impact on file-provisioning
update all methods to accept identity.Requester that contains all permissions and is required by access control.
* create deltas for single rul e
* update modify methods
skip new authorization logic if user CanWriteAllRules to avoid performance impact on file-provisioning
update all methods to accept identity.Requester that contains all permissions and is required by access control.
* implement RuleAccessControlService in provisioning

* update provisioning API to return errutil errors correctly
