poold(1M) System Administration Commands poold(1M)NAMEpoold - automated resource pools partitioning daemon
SYNOPSISpoold [-l level]
DESCRIPTIONpoold provides automated resource partitioning facilities. Normally,
poold is active on the system whenever the pools facility is active.
poold starts and stops when the pool_set_status(3POOL) function acti‐
vates or deactivates the pools facility. poold starts when you activate
pools and stops when you deactivate pools. If you manually stop poold
by using a utility such as kill(1), you can invoke it manually.
poold's configuration details are held in a libpool(3LIB) configuration
and you can access all customizable behavior from this configuration.
poold periodically examines the load on the system and decides whether
intervention is required to maintain optimal system performance with
respect to resource consumption. poold also responds to externally ini‐
tiated (with respect to poold) changes of either resource configuration
or objectives.
If intervention is required, poold attempts to reallocate the available
resources to ensure that performance objectives are satisfied. If it is
not possible for poold to meet performance objectives with the avail‐
able resources, then a message is written to the log. poold allocates
scarce resources according to the objectives configured by the adminis‐
trator. The system administrator must determine which resource pools
are most deserving of scarce resource and indicate this through the
importance of resource pools and objectives.
OPTIONS
The following options are supported:
-l level Specify the vebosity level for logging information.
Specify level as ALERT, CRIT, ERR, WARNING, NOTICE,
INFO, and DEBUG. If level is not supplied, then the
default logging level is INFO.
ALERT A condition that should be corrected
immediately, such as a corrupted system
database.
CRIT Critical conditions, such as hard
device errors.
ERR Errors.
WARNING Warning messages.
NOTICE Conditions that are not error condi‐
tions, but that may require special
handling.
INFO Informational messages.
DEBUG Messages that contain information nor‐
mally of use only when debugging a pro‐
gram.
When invoked manually, with the -l option, all log output is directed
to standard error.
EXAMPLES
Example 1: Modifying the Default Logging Level
The following command modifies the default logging level to ERR:
# /usr/lib/pool/poold -l ERR
