numastatd(1M) numastatd(1M) NAME numastatd - maintain NUMAlink device status and statistics data SYNOPSIS /usr/sbin/numastatd [ -w|-n nice ] [ -i interval ] DESCRIPTION numastatd will at certain intervals specified by the interval parameter (default is 10s) poll NUMAlink device status and statistics data and save the result in kernel internal data structures. The values may be retrieved with specific tools such as linkstat or pcp. On large systems this process may consume significant CPU time. In such instances where this is undesirable the scheduling characteristics of the process may be altered via the -w and -n nice parameters. These options are exclusive. This program will fork automatically into the background and disconnect from the current session and controlling terminal. The following options apply to numastatd: -w Specifies that numastatd should be scheduled as a weightless process. This option may not be specified together with the -n option. -n Specifies the absolute nice level at which the process should be scheduled. The range is 1 through 39 and lower numbers specify a higher priority. The default is normal timeshare (20) priority. -i The interval at which the data should be polled. The default is 10 seconds. A too long interval may lead to overflows in the data and will make the results inaccurate. DIAGNOSTICS Errors that occur during the initial configuration phase are printed to standard error. Errors occuring during runtime are logged to syslog. SEE ALSO linkstat(1), schedctl(2) Page 1[top]
