# 20-Jun-2026 — heap-usage gauge on the memory diagnostics page [#291](https://github.com/nbarrett/ngx-ramblers/issues/291)

## [build 706](https://github.com/nbarrett/ngx-ramblers/actions/runs/27881461706) — [commit dcfa2d4](https://github.com/nbarrett/ngx-ramblers/commit/dcfa2d4924de57b92dd473f3c8f15f211832c8fc)

_____

Adds a colour-coded progress bar showing heapUsed as a percentage of the V8
heap size limit (green < 70%, amber 70-85%, red >= 85%) plus a status line
(Healthy / Elevated / Critical), so the criticality of a site's memory is
visible at a glance rather than read from the raw table. Uses the data the
page already fetches from /api/health/memory; the heap-versus-limit ratio is
what actually drives the GC-thrash slowness, so that is what the gauge tracks.
