DESCRIPTIONrschedule will report or set status for load distribution using the
Perl Schedule::Load package.
If symbolically linked to the name "rtop" rschedule will by default
produce a listing of each host and the top loads on those hosts.
Similarly, a link to "rhosts" will show the host report by default, and
a link to "rloads" will show the load report.
COMMANDS
allow_class <class>
Sets the hostname to allow the specified class of jobs. This
sticks across reboots.
best
Returns the best host for a new job.
best_or_none
Returns the best host if there are free CPUs laying around, else
fails.
classes
Displays a listing of the classes of jobs each host can run.
cmnd_comment <pid>
Sets the command comment for the given process ID. In rschedule
top (rtop) displays, this will be shown rather than the name of the
command. Command comments are inherited by children of commented
parents.
deny_class <class>
Sets the hostname to deny the specified class of jobs.
fixed_load <pid>
Sets the given process ID to have that process count as one host
load, even if it is using less CPU time than that due to high disk
activity or other sleeps.
holds
Displays a listing of jobs that are blocked waiting for resources.
hosts
Displays a listing of each host being monitored along with its load
and system type.
hostnames
Displays list of each hostname. Multi-CPU hosts appear once.
idle_host_names
Displays list of each idle CPU. Multi-CPU hosts appear multiple
times.
loads
Displays a longer command line of top jobs, along with any
fixed_load jobs.
release
Releases a host from dedicated use. Use --host to specify which
host.
Any person may release a host, not just the original user
requesting the reservation. You may also use "release reserve"
together to change an existing reservation.
reserve
Reserves a host for dedicated use. To be reservable the
"reservable" flag must be set when that host's slreportd is
invocated. This is indicated on the top report by a "R" in the
column next to the command. To override a existing reservation you
need to release the reservation first. Use --host to specify which
host. A optional --comment specifies the reservation comment; the
default time and user will be prepended unless a leading - is used.
set_const var=value
Sets a constant reporter parameter to the specified value.
Slreportd will loose the information when rebooted, so this should
only be used to avoid restarting the daemon after changing the
slreportd's boot flags.
set_stored var=value
Sets a stored reporter parameter to the specified value. Slreportd
will keep the information when rebooted, and override any set_const
setting.
sleep secs
For debugging only, sleep the specified number of seconds.
status
Displays a listing of each host and its daemon's status. Intended
only for debugging problems with the scheduler.
top Displays a listing of top processes across all hosts being
monitored.
ARGUMENTS--allow-reserved
--no-allow-reserved
Specifies if reserved hosts may be returned by the best,
best_or_none, hostnames, idle_host_names, and jobs commands.
--class <class>
Specifies the job class for the best, best_or_none, hostnames,
idle_host_names, and jobs commands.
--comment <comment>
Specifies the command comment for the cmnd_comment command.
--dhost <hostname>
Specifies the host name that slchoosed uses. May be specified
multiple times to specify backup hosts. Defaults to SLCHOOSED_HOST
environment variable, which contains colon separated host names.
--help
Displays this message and program version and exits.
--kill <signal>
With the "loads" command, convert the listing to a form that will
login to the host and kill the processes. With a argument, use the
argument as the signal name.
--load <load>
Specifies the load value for the fixed_load command, defaults to 1.
--port <portnumber>
Specifies the port number that slchoosed uses.
--similar
Specifies only machines with the same OS version as the current
host should be returned for the best, best_or_none, hostnames,
idle_host_names, and jobs commands.
--version
Displays program version and exits.
