Finally fixed: "the random waves of suck" bug that's plagued @LibreQoS for 3 years.
I wrote up the journey - paying tribute to Dave, who battled this with me from
the start.

No more lock storms!

Fixing the Reload Penalty in LibreQoS

LibreQoS provides quality-of-experience (QoE) shaping and analysis for users, but it has had a major pain point for a long time. Since LibreQoS version 1.4 (released in November 2023), reloading users and the shaping tree could stall the processing pipeline, leading to bursts of packet loss. One of my colleagues even called it “random waves of suck” - a sudden burst of trouble across the network.

#LibreQoS Executive Dashboard:

We decided to display the global network-wide statistics as a simple heatmap.

Utilization, #QoO - Quality of Outcome, round-trip time, and retransmits follow a similar pattern.

A huge thank you to @nlnetfdn @nlnet for sponsoring this development.

LibreQoS Executive Dashboard

We’ve been working on something special for LibreQoS. The Insight heatmaps are popular - but feedback has indicated that sometimes they aren’t very clear - and it still requires a fair amount of effort to pinpoint problems.
