FibersMXBean (quasar-core 0.7.10 API)

```
public interface FibersMXBean
```
An MXBean that monitors fibers scheduled by a single FiberScheduler.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`long[]`	`getAllFiberIds()` The IDs of all fibers in the scheduler.
`FiberInfo[]`	`getFiberInfo(long[] ids, boolean stack)` Returns an array `FiberInfo` objects for a set of fibers.
`FiberInfo`	`getFiberInfo(long id, boolean stack)` Returns a `FiberInfo` object for a single fiber.
`long`	`getMeanTimedWakeupLatency()` The average latency between the time fibers in the scheduler have asked to be awakened (by a `sleep` or any other timed wait) and the time they've actually been awakened in the last 5 seconds.
`int`	`getNumActiveFibers()` The number of non-terminated fibers in the scheduler.
`int`	`getNumRunnableFibers()` The number of fibers currently in the `RUNNING` state.
`int`	`getNumWaitingFibers()` The number of fibers that are currently blocking.
`java.util.Map<java.lang.String,java.lang.String>`	`getRunawayFibers()` The fibers (and respective stack traces) that are currently holding their thread for a lengthy duration, either due to blocking or a lengthy loop.
`long`	`getSpuriousWakeups()`
`int`	`getTimedQueueLength()`
`void`	`refresh()`

```
    The fibers (and respective stack traces) that are currently holding their thread for a lengthy duration, either due to blocking or a lengthy loop.
  - getSpuriousWakeups
```
long getSpuriousWakeups()
```
  - getMeanTimedWakeupLatency

  - getAllFiberIds
```
long[] getAllFiberIds()
```
    The IDs of all fibers in the scheduler. null if the scheduler has been constructed with detailedInfo equal to false.
  - getFiberInfo
```
FiberInfo getFiberInfo(long id,
                       boolean stack)
```
    Returns a FiberInfo object for a single fiber. Returns null if the scheduler has been constructed with detailedInfo equal to false.
    
    Parameters:
    
    id - the fiber's id.
    
    stack - whether the fiber's call stack is required.
    
    Returns:
    
    a FiberInfo object for a single fiber, or null if the scheduler has been constructed with detailedInfo equal to false.
  - getFiberInfo
```
FiberInfo[] getFiberInfo(long[] ids,
                         boolean stack)
```
    Returns an array FiberInfo objects for a set of fibers. Returns null if the scheduler has been constructed with detailedInfo equal to false.
    
    Parameters:
    
    ids - the fibers' ids.
    
    stack - whether the fibers' call stack is required.
    
    Returns:
    
    an array FiberInfo objects for a set of fibers, or null if the scheduler has been constructed with detailedInfo equal to false.
