feat: failure rate sparkline per queue + QueueStats service object#35
Merged
Conversation
Add a mini 12-bar failure-rate sparkline to each row of the Queues table showing the percentage of jobs that failed (vs. completed) in each of the last 12 hours. Bars are red and proportional to the rate (0–100 %); hovering shows the hour and exact percentage; queues with no activity show "—". Extract all five index queries (completed_24h, failed_24h, oldest_ready, failure_sparklines) from QueuesController into a QueueStats service object so the action stays thin.
