* Alerting: Fix alert flapping in the alertmanager fixes a bug that caused Alerts that are evaluated at low intervals (sub 1 minute), to flap in the Alertmanager. Mostly due to a combination of `EndsAt` and resend delay. The Alertmanager uses `EndsAt` as a heuristic to know whenever it should resolve a firing alert, in the case that it hasn't heard back from the alert generation system. Because grafana sent the alert with an `EndsAt` which is equal to the `For` of the alert itself, and we had a hard-coded 1 minute re-send delay (only applicable to firing alerts) this meant that a firing alert would resolve in the Alertmanager before we re-notify that it still firing. This commit, increases the `EndsAt` by 3x the the resend delay or alert interval (depending on which one is higher). The resendDelay has been decreased to 30 seconds. |

The open-source platform for monitoring and observability.
Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture:
- Visualize: Fast and flexible client side graphs with a multitude of options. Panel plugins offer many different ways to visualize metrics and logs.
- Dynamic Dashboards: Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
- Explore Metrics: Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
- Explore Logs: Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
- Alerting: Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
- Mixed Data Sources: Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.
