Overview

Daily processed and failed counts, for the one question every other number on the dashboard cannot answer: is this normal?

30,655 failures is alarming or unremarkable depending on the day, and a live throughput chart that starts empty on every page load cannot tell you which.

Sidekiq already records this — Sidekiq::Stats::History keeps a counter per day and Roundhouse ignored it entirely. So this needs no storage of its own, no migration, and it works on every Sidekiq install. See #61.

Instance Method Details

#failure_rate ⇒ Object

Share of the day's work that failed. The line worth drawing: counts move with traffic, so a busy Monday looks worse than a quiet Sunday even when nothing changed. A rate does not.
