8.2 KiB · Rust · last changed Insights: OxygenFlow's standard charts, for the site, an owner and a repository 18 days ago source blame history raw
1 
//! Insights pages (oxygenhub#257): one page at three scopes, so the numbers
2 
//! always agree: the site (`/admin/insights`, administrators), an owner
3 
//! (`/insights/{owner}`, the owner, its members and administrators) and a
4 
//! repository (`/{owner}/{name}/insights`, anyone who reads it). `?range=`
5 
//! is `1h`, `24h` (default) or `7d`; the site page also takes `repo` and
6 
//! `runner`; `?wall=1` is the second-monitor view. The page refreshes its
7 
//! numbers every 30 seconds (hub.js), and works as a snapshot without it.
