* Alerting: Prevent short uid collision in legacy migration when db is case-insensitive Two factors come into play that cause sporadic uid conflicts during legacy alert migration: - MySQL and MySQL-compatible backends use case-insensitive collation. - Our short uid generator is not a uniform RNG and generates uids in such a way that generations in quick succession have a higher probability of creating similar uids. Normally we would be guaranteed unique short uid generation, however if the source alphabet contains duplicate characters (for example, if we use case-insensitive comparison) this guarantee is void. Generating even ~1000 uids in quick succession is nearly guaranteed to create a case-insensitive duplicate.
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.
