OpenflowSight is a Streamlit-based tool for searching, filtering, and analyzing Openflow telemetry data, inspired by Azure App Insights Search UX.
It’s a log explorer focused on Openflow telemetry. It helps you quickly identify relevant events, see when they spiked, and which processors were involved. Search, group similar events, and export results for deeper offline analysis.
Openflow is an exciting new unified data integration tool from Snowflake based on Apache NiFi. Logs, traces, and metrics emitted at runtime are written to the Event table which supports the OpenTelemetry data model. OpenflowSight surfaces this data to enable convenient, efficient monitoring and analysis of Openflow operations from a graphical dashboard—instead of using SQL queries.
