This pull request updates our fork of Alertmanager to commit 65bdab0, which is based on commit 5658f8c in Prometheus Alertmanager.
It applies the changes from grafana/alerting#155 which removes the overrides for validation of alerts, labels and silences that we had put in place to allow alerts and silences to work for non-Prometheus datasources. However, as this is now supported in Alertmanager with the UTF-8 work, we can use the new upstream functions and remove these overrides.
The compat package is a package in Alertmanager that takes care of backwards compatibility when parsing matchers, validating alerts, labels and silences. It has three modes: classic mode, UTF-8 strict mode, fallback mode. These modes are controlled via compat.InitFromFlags. Grafana initializes the compat package without any feature flags, which is the equivalent of fallback mode. Classic and UTF-8 strict mode are used in Mimir.
While Grafana Managed Alerts have no need for fallback mode, Grafana can still be used as an interface to manage the configurations of Mimir Alertmanagers and view configurations of Prometheus Alertmanager, and those installations might not have migrated or being running on older versions. Such installations behave as if in classic mode, and Grafana must be able to parse their configurations to interact with them for some period of time. As such, Grafana uses fallback mode until we are ready to drop support for outdated installations of Mimir and the Prometheus Alertmanager.

This PR has two steps that together create a functional dry-run capability for the migration.
By enabling the feature flag alertingPreviewUpgrade when on legacy alerting it will:
a. Allow all Grafana Alerting background services except for the scheduler to start (multiorg alertmanager, state manager, routes, …).
b. Allow the UI to show Grafana Alerting pages alongside legacy ones (with appropriate in-app warnings that UA is not actually running).
c. Show a new “Alerting Upgrade” page and register associated /api/v1/upgrade endpoints that will allow the user to upgrade their organization live without restart and present a summary of the upgrade in a table.
* (WIP) Alerting: Use the forked Alertmanager for remote secondary mode
* fall back to using internal AM in case of error
* remove TODOs, clean up .ini file, add orgId as part of remote AM config struct
* log warnings and errors, fall back to remoteSecondary, fall back to internal AM only
* extract logic to decide remote Alertmanager mode to a separate function, switch on mode
* tests
* make linter happy
* remove func to decide remote Alertmanager mode
* refactor factory function and options
* add default case to switch statement
* remove ineffectual assignment
* Add Loki historian store stub
* Add composite store
* Use composite store if Loki historian enabled
* Split store interface into read/write
* Make composite + historian stores read only
* Use variadic constructor for composite
* Modify Loki store enable logic
* Use dskit.concurrency.ForEachJob for parallelism
* Alerting: Only warm alert state cache if execute_alerts=true.
If the Grafana instance is not executing alerts, then Warm()-ing the state
manager is wasteful and could lead to misleading rule status queries, as the
status returned will be always based on the state loaded from the database at
startup, and not the most recent evaluation state.
* Move Warm() down to shared conditional.
* Alerting: Add GetFullState method to FileStore
* make tests compile, create stateStore in NewAlertmanager
* return errors instead of logging, accept an arbitrary number of strings
* make NewAlertmanager() accept a stateStore
* Alerting: Move `ExternalAlertmanager` to its own package
We'll avoid import cycles when using components from other packages. In addition to that, I've created an `Options` approach for the multiorg alertmanger to allow us to override how per tenant alertmanagers are created.
* switch things around
* address review comments
* fix references and warnings
* Alerting: Move migration from background service run to ngalert init
sqlite database write contention between the migration's single transaction and
dashboard provisioning's frequent commits was causing the migration to
fail with SQLITE_BUSY/SQLITE_BUSY_SNAPSHOT on all retries.
This is not a new issue for sqlite+grafana, but the discrepancy between the
length of the transactions was causing it to be very consistent. In addition,
since a failed migration has implications on the assumed correctness of the
alertmanager and alert rule definition state, we cause a server shutdown on
error. This can make e2e tests as well as some high-load provisioned
sqlite installations flaky on startup.
The correct fix for this is better transaction management across various
services and is out of scope for this change as we're primarily interested in
mitigating the current bout of server failures in e2e tests when using sqlite.
This PR replaces the vendored models in the migration with their equivalent ngalert models. It also replaces the raw SQL selects and inserts with service calls.
It also fills in some gaps in the testing suite around:
- Migration of alert rules: verifying that the actual data model (queries, conditions) are correct 9a7cfa9
- Secure settings migration: verifying that secure fields remain encrypted for all available notifiers and certain fields migrate from plain text to encrypted secure settings correctly e7d3993
Replacing the checks for custom dashboard ACLs will be replaced in a separate targeted PR as it will be complex enough alone.
* Alerting: Don't use a separate collection system for metrics
The state package had a metric collection system that ran every 15s updating the values of the metrics - there is a common pattern for this in the Prometheus ecosystem called "collectors".
I have removed the behaviour of using a time-based interval to "set" the metrics in favour of a set of functions as the "value" that get called at scrape time.
* add metrics and tracing to state manager
* propagate tracer to state manager
* add scheduler metrics
* fix backtesting
* add test for state metrics
* remove StateUpdateCount
* update docs
* metrics can be null
* add tracer to new tests
* introduce a new action "alert.provisioning.secrets:read" and role "fixed:alerting.provisioning.secrets:reader"
* update alerting API authorization layer to let the user read provisioning with the new action
* let new action use decrypt flag
* add action and role to docs
This commit adds support for concurrent queries when saving alert
instances to the database. This is an experimental feature in
response to some customers experiencing delays between rule evaluation
and sending alerts to Alertmanager, resulting in flapping. It is
disabled by default.
