ByteBufAllocator metrics

metric name	type	description
reactor.netty.bytebuf.allocator.used.heap.memory	Gauge	The number of bytes reserved by heap buffer allocator. See [observability-metrics-used-heap-memory]
reactor.netty.bytebuf.allocator.used.direct.memory	Gauge	The number of bytes reserved by direct buffer allocator. See [observability-metrics-used-direct-memory]
reactor.netty.bytebuf.allocator.heap.arenas	Gauge	The number of heap arenas (when PooledByteBufAllocator). See [observability-metrics-heap-arenas]
reactor.netty.bytebuf.allocator.direct.arenas	Gauge	The number of direct arenas (when PooledByteBufAllocator). See [observability-metrics-direct-arenas]
reactor.netty.bytebuf.allocator.threadlocal.caches	Gauge	The number of thread local caches (when PooledByteBufAllocator). See [observability-metrics-thread-local-caches]
reactor.netty.bytebuf.allocator.small.cache.size	Gauge	The size of the small cache (when PooledByteBufAllocator). See [observability-metrics-small-cache-size]
reactor.netty.bytebuf.allocator.normal.cache.size	Gauge	The size of the normal cache (when PooledByteBufAllocator). See [observability-metrics-normal-cache-size]
reactor.netty.bytebuf.allocator.chunk.size	Gauge	The chunk size for an arena (when PooledByteBufAllocator). See [observability-metrics-chunk-size]
reactor.netty.bytebuf.allocator.active.heap.memory	Gauge	The actual bytes consumed by in-use buffers allocated from heap buffer pools (when PooledByteBufAllocator). See [observability-metrics-active-heap-memory]
reactor.netty.bytebuf.allocator.active.direct.memory	Gauge	The actual bytes consumed by in-use buffers allocated from direct buffer pools (when PooledByteBufAllocator). See [observability-metrics-active-direct-memory]
