# tui/app-threads List active app threads with per-app metrics. Returns a list of maps, one per running app thread: ``` %{ :name <string> # app name (e.g. "editor", "sysmon") :tid <number> # OS thread ID (for /proc/self/task/<tid>/stat) :panel-id <number> # workspace panel ID hosting this app :heap-kb <number> # live GC heap bytes / 1024 (direct read, no IPC) :peak-heap-kb <number> # peak GC heap allocation / 1024 :gc-cycles <number> # GC collection cycles (gc/stats :cycles) :gc-freed-kb <number> # cumulative GC bytes freed / 1024 :next-gc-kb <number> # next-GC heap threshold / 1024 } ```` Heap and GC stats are read directly from the app's `Runtime.vm.heap` — no remote eval or serialization needed. Values may be slightly stale (cross-thread read without locking) but are fine for monitoring. ## Syntax
