Detailed Description

Pool statistics counters.

In addition to API alloc and free calls, statistics counters may be updated by alloc/free operations from implementation internal software or hardware components.

Field Documentation

alloc_ops

uint64_t odp_pool_stats_t::alloc_ops

The number of alloc operations from the pool.

Includes both successful and failed operations (pool empty).

Examples

odp_pool_perf.c.

Definition at line 107 of file api/spec/pool_types.h.

total_ops

uint64_t odp_pool_stats_t::total_ops

The total number of alloc and free operations.

Includes both successful and failed operations (pool empty).

Examples

odp_pool_perf.c.

Definition at line 117 of file api/spec/pool_types.h.

cache_available

uint64_t odp_pool_stats_t::cache_available[ODP_POOL_MAX_THREAD_STATS]

The number of available events in the local caches of all threads.

The number of available events in each thread local cache.

If 'first' and 'last' include all threads of the instance, the sum of 'thread.cache_available' matches 'cache_available'.

Examples

odp_pool_perf.c.

Definition at line 120 of file api/spec/pool_types.h.

first

uint16_t odp_pool_stats_t::first

First thread identifier to read counters from.

Ignored when 'thread.cache_available' is not enabled.

Examples

odp_pool_perf.c.

Definition at line 133 of file api/spec/pool_types.h.

last

uint16_t odp_pool_stats_t::last

Last thread identifier to read counters from.

Ignored when 'thread.cache_available' is not enabled.

Examples

odp_pool_perf.c.

Definition at line 137 of file api/spec/pool_types.h.
