Apr 1, 2025April 2025 — Porter Charts (porter-dev/porter-charts) delivered a focused dashboard enhancement and ensured dashboard metadata accuracy, driving clearer insights and improved governance of metrics across Porter dashboards. Key changes implemented in this period include the Porter Dashboard Enhancement, which integrates existing dashboard queries and adds new ones to provide a more comprehensive metrics view. This work reinforces data-driven decision-making for product and business stakeholders by expanding visibility into core KPIs and performance indicators. A companion effort for metadata accuracy corrected the Dashboard Description to reflect the intended fix, ensuring the dashboard’s metadata remains aligned with its capabilities.

Jan 1, 2025January 2025 performance summary for porter-charts: Delivered two feature enhancements that broaden deployment flexibility and observability. Grafana add-on: introduced a new template and updated ingress logic to support multiple wildcard ingress configurations, enabling multiple host-specific rules for more flexible Grafana routing. Datadog add-on: extended DaemonSet tolerations to allow deployment on non-default node groups (porter.run/node-group-id) and GPU-enabled nodes (nvidia.com/gpu), expanding monitoring coverage across diverse workloads and hardware. These changes reduce onboarding friction, improve reliability of Grafana access across environments, and extend observability to GPU nodes and non-default worker pools. Overall impact: increased deployment flexibility, broader visibility, and lower operational risk when scaling or evolving cluster topologies. Technologies/skills demonstrated: Kubernetes scheduling (tolerations), DaemonSet management, Helm templating, and multi-host ingress templating.
