    Use Cases & Benefits

    • Provides an open-source alerting engine focused on generating, processing, and distributing monitoring alarms from various data sources.
    • Offers flexible alerting rules, multi-protocol data integration, and distributed deployment for reliable alerting even in poor network conditions.
    • Use for setting up centralized alerting systems that integrate with existing time-series databases like Prometheus or VictoriaMetrics.
    • Use for deploying edge alerting engines in remote data centers to maintain alerting functionality despite network disruptions.
    • Use for automating alert noise reduction and customized notification workflows across multiple notification channels like SMS, email, and Slack.

    From the README

    Nightingale is an open-source monitoring project that focuses on alerting. Similar to Grafana, Nightingale also connects with various existing data sources. However, while Grafana emphasizes visualization, Nightingale places greater emphasis on the alerting engine, as well as the processing and distribution of alarms.

    The Nightingale project was initially developed and open-sourced by DiDi.inc. On May 11, 2022, it was donated to the Open Source Development Committee of the China Computer Federation (CCF ODC).

    Many users have already collected metrics and log data. In this case, you can connect your storage repositories (such as VictoriaMetrics, ElasticSearch, etc.) as data sources in Nightingale. This allows you to configure alerting rules and notification rules within Nightingale, enabling the generation and distribution of alarms.

    Nightingale itself does not provide monitoring data collection capabilities. We recommend using Categraf as the collector, which integrates seamlessly with Nightingale.

    Categraf can collect monitoring data from operating systems, network devices, various middleware, and databases. It pushes this data to Nightingale via the Prometheus Remote Write protocol. Nightingale then stores the monitoring data in a time-series database (such as Prometheus, VictoriaMetrics, etc.) and provides alerting and visualization capabilities.
