SLREPORTD(1) User Contributed Perl Documentation SLREPORTD(1)NAMEslreportd - Distributed load reporter for Perl Schedule::Load
SYNOPSISslreportd [ --help ] [ --port=port ] [ --dhost=host ] [ --version ]
DESCRIPTIONslreportd will start a daemon to report machine loading for the
Schedule::Load package. It will create two similar processes, so that
if second process exits, the first may restart it automatically.
slreportd must be running on every host in the network, usually started
with a init.d script. It reports itself to the slchoosed daemon
periodically, and is responsible for checking loading and top processes
specific to the host that it runs on.
slreportd may also be invoked with some variables set. This allows
static host information, such as class settings to be passed to
applications.
ARGUMENTS--help
Displays this message and program version and exits.
--dhost
Specifies the daemon 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.
--fake
Specifies load management should not be used, for reporting of a
"fake" hosts' status. Often the hostname and other parameters will
want to be overridden, for example:
slreportd hostname=lab_1 cpus=1 max_clock=100 osname=myos osvers=1
archname=myarch reservable=1 load_limit=1
--nofork
For debugging, prevents the daemon from creating additional
processes and from going into the background. This allows messages
to appear on stdout, and ctrl-C to stop the daemon.
--port
Specifies the port number that slchoosed uses. Defaults to
SLCHOOSED_PORT environment variable or slchoosed service, or 1752.
--version
Displays program version and exits.
{variable}={value}
Sets a arbitrary constant variable to the specified value. This
variable may be used so that a process requesting a machine can
choose a machine with specific properties.
dynamic_cache_timeout={secs}
When set, after this number of seconds the dynamic load
information for this host will no longer be cached by
slchoosed, and when next needed must be reread from the
slreportd. If not set, slchooserd picks a default, currently
10 seconds. Turning this number up may improve performance at
the cost of decreased accuracy.
load_limit={value}
Set a maximum number of jobs that the scheduler can run on this
machine.
load_pctcpu={1|0}
When set, determine load as a floating point number based on
CPU usage percentage of all tasks. Default, or when clear,
load is a absolute number where each high CPU job counts as one
job, regardless of what percentage of the CPU is used. Using
pctcpu tends to keep CPUs busy more often, at the possible
expense of slowing down interactive jobs that are not using an
entire CPU.
rating_adder={value}
Add the specified value to the rating obtained for the machine.
A positive rating will make the machine less desirable for
scheduling.
rating_mult={value}
Multiply the specified value to the rating obtained for the
machine. The value 2 would act the same as a halved clock
frequency, making the machine less desirable for scheduling.
