Matthew Jacobson	940d18ad57	Alerting: Sanitize invalid label/annotation names for external alertmanagers (#54537 ) * Alerting: Sanitize invalid label/annotation names for external alertmanagers Grafana's built-in Alertmanager supports both Unicode label keys and values; however, if using an external Prometheus Alertmanager label keys must be compatible with their data model. This means label keys must only contain ASCII letters, numbers, as well as underscores and match the regex `[a-zA-Z_][a-zA-Z0-9_]`. Any invalid characters will now be removed or replaced by the Grafana alerting engine before being sent to the external Alertmanager according to the following rules: - `Whitespace` will be removed. - `ASCII characters` will be replaced with `_`. - `All other characters` will be replaced with their lower-case hex representation. Prefix hex replacements with `0x` * Refactor for clarity * Apply suggestions from code review Co-authored-by: brendamuir <100768211+brendamuir@users.noreply.github.com> Co-authored-by: brendamuir <100768211+brendamuir@users.noreply.github.com>	3 years ago

Yuriy Tseretyan	054fe54b03	Alerting: Split Scheduler and AlertRouter tests (#52416 ) * move fake FakeExternalAlertmanager to sender package * move tests from scheduler to router * update alerts router to have all fields private * update scheduler tests to use sender mock	3 years ago
Yuriy Tseretyan	a6b1090879	Alerting: refactor scheduler and separate notification logic (#48144 ) * Introduce AlertsRouter in the sender package, and move all fields and methods related to notifications out of the scheduler to this router. * Introduce a new interface AlertsSender in the schedule package and replace calls of anonymous function `notify` inside the ruleRoutine to calling methods of that interface. * Rename interface Scheduler in api package to ExternalAlertmanagerProvider, and replace scheduler with AlertRouter as struct that implements the interface.	3 years ago

gotjosh	a2f4344bf2	Alerting: Refactor & fix unified alerting metrics structure (#39151 ) * Alerting: Refactor & fix unified alerting metrics structure Fixes and refactors the metrics structure we have for the ngalert service. Now, each component has its own metric struct that includes the JUST the metrics it uses. Additionally, I have fixed the configuration metrics and added new metrics to determine if we have discovered and started all the necessary configurations of an instance. This allows us to alert on `grafana_alerting_discovered_configurations - grafana_alerting_active_configurations != 0` to know whether an alertmanager instance did not start successfully.	4 years ago
gotjosh	f83cd401e5	Alerting: Send alerts to external Alertmanager(s) (#37298 ) * Alerting: Send alerts to external Alertmanager(s) Within this PR we're adding support for registering or unregistering sending to a set of external alertmanagers. A few of the things that are going are: - Introduce a new table to hold "admin" (either org or global) configuration we can change at runtime. - A new periodic check that polls for this configuration and adjusts the "senders" accordingly. - Introduces a new concept of "senders" that are responsible for shipping the alerts to the external Alertmanager(s). In a nutshell, this is the Prometheus notifier (the one in charge of sending the alert) mapped to a multi-tenant map. There are a few code movements here and there but those are minor, I tried to keep things intact as much as possible so that we could have an easier diff.	4 years ago
