# readyFiberCount

## Category
Scheduler Management

## Arity
**Unary** — `readyFiberCount <schedulerId>`.

```
readyFiberCount <number>
```

## Description
Returns the number of **ready** fibers on the given scheduler — fibers that are not sleeping or awaiting and are eligible to run on the next scheduler tick. High ready count means the scheduler has work queued up.

## How It Works
Counts fibers in the scheduler's ready queue only — excludes fibers in the waiting list (sleep/await).

## Usage

```sqf
_ready = readyFiberCount 1;    // e.g., 5
systemChat f"Ready fibers: {_ready}";
```

### Detect backlog
```sqf
_ready = readyFiberCount _schedulerId;
if (_ready > 50) then {
    systemChat f"Scheduler {_schedulerId} backlogged: {_ready} fibers waiting";
};
```

### With fiberCount
```sqf
_total = fiberCount 1;
_ready = readyFiberCount 1;
_pctReady = if (_total > 0) then { _ready / _total * 100 } else { 0 };
systemChat f"{_pctReady}% fibers ready to run";
```

## Thread Safety
ReadOnly — approximate snapshot. Safe from any scheduler.
