Grafana
Open-source observability and visualization platform. Builds dashboards over metrics, logs, and traces from sources like Elasticsearch, Prometheus, and flow-analytics tools; commonly paired with Elastiflow for network traffic dashboards. For logs specifically, Grafana is the direct open-source alternative to Kibana — pairing with Loki (log storage) and Promtail/Alloy (log shipping) as the "PLG stack," a lighter-weight alternative to the ELK stack (Elasticsearch + Logstash/Filebeat + Kibana) since Loki indexes only labels rather than full log text.
