Arguments: &key new sum error-p slot pool

This function accesses or manages statistics maintained by jlinker about the behavior and performance of the connection pool.

If the sum argument is specified, it must be a pool statistics instance obtained in a previous call to jpool-statistics.

If the slot argument is non-nil, it must be one of the following keywords to retrieve the corresponding value from a statistics instance. When slot is non-nil, the new argument is ignored. If sum is specified (as a statistics instance), the value returned comes from that instance. If sum is nil or unspecified, the value comes from the current pool.

The following slots refer to non-pool and pool ports combined:

If the slot argument is omitted or nil, the return value is always a new pool statistics instance in which the values are copied atomically from the current pool. When sum is specified, it is updated from the current value as a side-effect. The :max slot is the maximum of two, the other slots are sums. (To be clear: when slot is nil, the return value is always a new statistics instance. When sum is also a statistics instance, that instance is updated but not returned.)

If the new argument is non-nil, the current pool statistics are reset to zero.

The pool argument is reserved for internal use and must not be specified.

See jlinker.htm for more information on the jLinker facility.
