Intelligent Monitoring: Automating Dashboard Annotations in Chronograf`
Chronograf has added support for annotating dashboard cells with interesting time-events, allowing users to note events such as abnormally high resource utilization or changes to infrastructure. These annotations are replicated across all dashboards and their respective cells, enabling correlation of events during root cause analysis. Chronograf exposes an annotations endpoint via its API, which can be used by Kapacitor to automatically annotate dashboards based on predefined rules for any metric or event. To leverage this feature, users must configure Kapacitor to POST to the annotations endpoint with a custom payload, which is achieved through editing the HTTPpost section of Kapacitor's configuration file. By following these steps, users can automate dashboard annotations and improve their ability to analyze events in real-time.
