* Alerting: During legacy migration reduce the number of created silences During legacy migration every migrated rule was given a label rule_uid=<uid>. This was used to silence DatasourceError/DatasourceNoData alerts for migrated rules that had either ExecutionErrorState/NoDataState set to keep_state, respectively. This could potentially create a large amount of silences and a high cardinality label. Both of these scenarios have poor outcomes for CPU load and latency in unified alerting. Instead, this change creates one label per ExecutionErrorState/NoDataState when they are set to keep_state as well as two silence rules, if rules with said labels were created during migration. These silence rules are: - __legacy_silence_error_keep_state__ = true - __legacy_silence_nodata_keep_state__ = true This will drastically reduce the number of created silence rules in most cases as well as not create the potentially high cardinality label `rule_uid`. |

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:
- Visualizations: 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.
