Statistics about the historical usage of the Pool.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

get_started: u64

Total gets started.

This counter is incremented before the get operation starts waiting, so that it’s possible to monitor the size of the queue by computing the difference with the other get_* statistics.

get_direct: u64

Total gets completed that did not have to wait for a connection.

get_waited: u64

Total gets completed that had to wait for a connection available.

get_timed_out: u64

Total gets completed that timed out while waiting for a connection.

get_wait_time: Duration

Total time accumulated waiting for a connection.

connections_created: u64

Total connections created.

connections_closed_broken: u64

Total connections that were closed due to be in broken state.

connections_closed_invalid: u64

Total connections that were closed due to be considered invalid.

connections_closed_max_lifetime: u64

Total connections that were closed because they reached the max lifetime.

connections_closed_idle_timeout: u64

Total connections that were closed because they reached the max idle timeout.
