<div dir="ltr">In larger environments which have heterogeneous resources it's frequently useful to look at utilization of various resources as percentages. The df plugin started to add this in 5.4 with the ReportAbsolute and ReportPercentage options being added. pyr then got the ball rolling on adding percentages for memory and swap (<a href="https://github.com/collectd/collectd/pull/501">https://github.com/collectd/collectd/pull/501</a> and <a href="https://github.com/collectd/collectd/pull/500">https://github.com/collectd/collectd/pull/500</a>) that I've also added a second set of patches so that percentages get reported for all of the values rather than just getting a percent used metric.<div>
<br></div><div>But all of these end up having a ton of repetition. As I was working on them and then starting to do the same for cpu utilization, it started to leave something of a bad taste in my mouth. I realized that we could do something that would be more global similar to how StoreRates is available in (most?) output plugins. To get there, we could add a value_total to value_list_t and then write plugins could use that to do a percentage calculation if StorePercentages was set. There would be a need to update both output plugins and input plugins instead of just input plugins but I think the changes would look a little cleaner.</div>
