Methods

[dispose]

"[dispose]"(): void
Same as destroy(), so a monitor can be declared with using. Present only where the runtime defines Symbol.dispose.

Returns void
- Defined in core/types/monitor.ts:210

destroy

destroy(): void
Stops collectors and releases signal subscriptions owned by this monitor.

Returns void
- Defined in core/types/monitor.ts:205

getSnapshot

getSnapshot(): MonitorSnapshot
Returns the latest combined snapshot synchronously.

Returns MonitorSnapshot
- Defined in core/types/monitor.ts:197

start

start(): void
Starts all enabled collectors. Safe to call in browsers; no-ops where unsupported.

Returns void
- Defined in core/types/monitor.ts:201

stop

stop(): void
Stops active collector hooks, timers, and patches.

Returns void
- Defined in core/types/monitor.ts:203

subscribe(cb: (snap: MonitorSnapshot) => void): () => void
Subscribes to combined snapshot changes and returns an unsubscribe function.
Parameters
- cb: (snap: MonitorSnapshot) => void
Returns () => void
- Defined in core/types/monitor.ts:199
