GrafanaCONline Day 8 highlighted the introduction of a new plugins platform in Grafana v7.0, designed to enable developers to create custom plugins more efficiently. Dominik Prokop, a software engineer at Grafana Labs, introduced new packages such as @grafana/ui, @grafana/data, @grafana/runtime, and @grafana/toolkit, and showcased a demo of the new declarative options API. Additionally, Matti Paksula demonstrated how he utilizes Grafana to visualize browser data for tracking site performance metrics in near real time. The day's sessions also included discussions on Prometheus rate queries and strategies for organizational adoption of telemetry solutions. Participants were encouraged to engage with the Grafana community via Slack for further updates and discussions.
