This is why I always have my visualizations overlay both failure rates and usage.
A given failure rate (or even worse, a failure count) doesn't tell you much about the system without also including the totals of both success and failure.
I'm sure I could be more rigorous with this though. Is there a way to express a given failure rate in terms of certainty? As in, we have sampled the failure rate of a component with fixed parameters a, b, c, and we are x% certain of the failure rate? (Maybe I'm wording this wrong - I don't have much of a stats background).

- Splines 10y agoSorry for the late reply - where I work we use an in-house platform that uses Kendo for rendering charts. http://demos.telerik.com/kendo-ui/bar-charts/column http://demos.telerik.com/kendo-ui/bar-charts/column What I do isn't anything particularly sophisticated, I usually do a multi-axis chart with a line & column chart, with one axis corresponding to usage, and the other axis corresponding to failure rate. Imagine a basic multi-axis chart in Excel, except rendered in a browser, and you're 90% of the way there.
