Resource monitor
See which terminal, language server or extension is using CPU and memory.
The resource monitor samples Rexa, each terminal, each language server, the extension host and the file watchers once a second. It lives in the status bar.
Status bar item
The item, a CPU icon, stays blank while everything is within budget. When something stays over budget for three samples in a row, the item names it, such as Rexa 3.2G.
Click the item for a popup with one section each for App, Terminals, Language servers, Extensions and Watchers. Rows show CPU and memory; watcher rows show events per second and how long git status takes. Hover a row for details.
Actions
Rows over the critical budget get an action. Each one asks first; nothing runs on its own.
| Row | Action | What happens |
|---|---|---|
| Terminal | Stop | Sends SIGTERM to its process. The tab stays open. |
| Language server | Restart | Restarts the language servers. |
| Extension host | Restart | Reloads every extension. |
Budgets
Each kind takes a [warn, critical] pair. CPU is a percentage of one core; memory is in GB.
| Kind | CPU | Memory |
|---|---|---|
app |
70 / 150 | 1.5 / 3 |
terminal |
150 / 300 | 2 / 4 |
lsp |
100 / 200 | 2 / 4 |
extension |
100 / 200 | 1.5 / 3 |
Watchers have eventsPerSec 200 / 1000 and gitStatusMs 2000 / 10000. Override any of them in settings:
{
"resources": {
"terminal": { "cpu": [200, 400], "memoryGb": [4, 8] }
}
