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.
:active: number of Lisp ports to Java in use at
some moment.
:max: maximum number of Lisp ports to Java in use.
:wait: number of seconds spent waiting for a Lisp
port to Java.
:free: number of times a port was obtained for a
call.
:busy: number of times a caller was told all ports
are busy.
The following slots refer to non-pool and pool ports combined:
:idle-wait: number of times a port was available
after waiting.
:idle-free: number of times a port was available
without waiting.
:idle-busy: number of times a port was not
available.
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.
