Grafana Alerting allows you to learn about problems in your systems moments after they occur.
Monitor your incoming metrics data or log entries and set up your Alerting system to watch for specific events or circumstances and then send notifications when those things are found.
In this way, you eliminate the need for manual monitoring and provide a first line of defense against system outages or changes that could turn into major incidents.
Using Grafana Alerting, you create queries and expressions from multiple data sources — no matter where your data is stored — giving you the flexibility to combine your data and alert on your metrics and logs in new and unique ways. You can then create, manage, and take action on your alerts from a single, consolidated view, and improve your team’s ability to identify and resolve issues quickly.
Grafana Alerting is available for Grafana OSS, Grafana Enterprise, or Grafana Cloud. With Mimir and Loki alert rules you can run alert expressions closer to your data and at massive scale, all managed by the Grafana UI you are already familiar with.
A single Grafana Alerting page consolidates both Grafana-managed alerts and alerts that reside in your Prometheus-compatible data source in one single place.
Alert rules can create multiple individual alert instances per alert rule, known as multi-dimensional alerts, giving you the power and flexibility to gain visibility into your entire system with just a single alert rule. You do this by adding labels to your query to specify which component is being monitored and generate multiple alert instances for a single alert rule. For example, if you want to monitor each server in a cluster, a multi-dimensional alert will alert on each CPU, whereas a standard alert will alert on the overall server.
Route each alert instance to a specific contact point based on labels you define. Notification policies are the set of rules for where, when, and how the alerts are routed to contact points.
Silences stop notifications from getting created and last for only a specified window of time.
Silences allow you to stop receiving persistent notifications from one or more alert rules. You can also partially pause an alert based on certain criteria. Silences have their own dedicated section for better organization and visibility, so that you can scan your paused alert rules without cluttering the main alerting view.
A mute timing is a recurring interval of time when no new notifications for a policy are generated or sent. Use them to prevent alerts from firing a specific and reoccurring period, for example, a regular maintenance period.
Similar to silences, mute timings do not prevent alert rules from being evaluated, nor do they stop alert instances from being shown in the user interface. They only prevent notifications from being created.
Monitoring complex IT systems and understanding whether everything is up and running correctly is a difficult task. Setting up an effective alert management system is therefore essential to inform you when things are going wrong before they start to impact your business outcomes.
