Struct CobaltPoolStatistics

Namespace

CobaltPdf

Assembly

CobaltPdf.dll

A point-in-time snapshot of the render pool's state and lifetime counters, returned by GetPoolStatistics(). Useful for health endpoints, capacity dashboards, and autoscaling signals.

The gauges (CurrentWorkers, LeasedWorkers, IdleWorkers, QueuedWaiters) are read without locking, so on a busy pool they are a close-but-not-transactional view; the cumulative counters are exact. Field-for-field identical to the CobaltPDF.WebKit edition's snapshot.

CobaltPoolStatistics(bool, int, int, int, int, int, int, int, long, long, long)

A point-in-time snapshot of the render pool's state and lifetime counters, returned by GetPoolStatistics(). Useful for health endpoints, capacity dashboards, and autoscaling signals.

The gauges (CurrentWorkers, LeasedWorkers, IdleWorkers, QueuedWaiters) are read without locking, so on a busy pool they are a close-but-not-transactional view; the cumulative counters are exact. Field-for-field identical to the CobaltPDF.WebKit edition's snapshot.

public CobaltPoolStatistics(bool Initialized, int MinSize, int MaxSize, int MaxQueueDepth, int CurrentWorkers, int LeasedWorkers, int IdleWorkers, int QueuedWaiters, long TotalRendersCompleted, long TotalRenderRetries, long TotalBusyRejections)

Parameters

Initialized bool

False if the pool has not been created yet (no render or PreWarmAsync() has run). Every other field is 0 in that case.

MinSize int

Configured MinSize.

MaxSize int

Configured MaxSize (the concurrent render ceiling).

MaxQueueDepth int

Configured MaxQueueDepth (0 = unbounded).

CurrentWorkers int

Live browser instances right now (idle + leased).

LeasedWorkers int

Browsers currently executing a render.

IdleWorkers int

Warm browsers sitting in the pool ready to serve.

QueuedWaiters int

Callers currently blocked waiting for a free slot.

TotalRendersCompleted long

Render leases processed over the pool's lifetime.

TotalRenderRetries long

Always 0 in this (Chromium) edition — it has no pool-level render retry. The field exists for snapshot parity with the WebKit edition (which retries transient worker failures).

TotalBusyRejections long

Requests rejected with PoolBusyException (backpressure).
