PHSTAT(l) PHSTAT(l) NAME phstat - shows various dynamic attributes of hosts being scheduled by LCRM SYNOPSIS phstat -h phstat [-c constraint] [-H] [-z] DESCRIPTION phstat is used to show various dynamic attributes of hosts being sched- uled by LCRM. The hosts shown can be delimited by a constraint by using the -c option. If the -c option is not used, attributes of all hosts are shown. The attributes displayed are: HOSTNAME The logical name of the host as declared via lrmmgr POOL The name of a pool or partition at the host that is scheduled by LCRM (applicable to multi-node hosts only) ID The hostid (index) of the host as known to pwsd AVAILABILITY Availability of the host as follows: x-ANBPLR:TWK x will have one of the following values: C the host is a cluster backfill scheduled host M the host is a memory backfill scheduled host N the host is a multi-node backfill scheduled host R the host is a multi-node non-backfill scheduled host ? the scheduler type for the machine is unknown 0 the scheduler type for the machine is not set The absence of a letter after the - should be interpreted at the negation of the condition implied by the presence of the letter. The pres- ence of a letter after the - should be interpreted as follows: A The machine is not active in the lrm domain N Jobs are not cur- rently being scheduled at the host B Batch jobs are not permit- ted at the host P The pspd at the machine is not connected to pwsd L The plsd at the machine is not connected to pwsd R The acctd at the machine is not connected to racmgr T schedul- ing has been inhibited for a timedout job W scheduling has been inhibited for a staging job K scheduling has been inhibited for a terminating job MEMORY Memory usage and size data as follows: Field 1 sum of resident set sizes of all processes on the machine Field 2 usable memory on the machine or subpool Field 3 percent of memory currently in use (memory load) NOTE: Fields 1 and 3 are applicable only on cluster and memory backfill scheduled machines CPU|NODE cpu or node usage as follows: Field 1 cpus (cluster machines only) or nodes (multi-node machines only) committed to jobs Field 2 total accountable cpus on the machine or total nodes in a subpool (multi-node scheduled machines only) SCHTIME Number of seconds that have elapsed since the last time the scheduler for the machine ran or 30 minutes OPTIONS -c constraint Only the attributes of the hosts that have features speci- fied by the constraint are shown. -H If specified, the header line that describe the fields is not displayed. This option is implied by the -z option. -z Causes fields to be displayed "raw". That is, the data is not interpreted and is displayed with only a single blank between fields. -h Causes a usage message to be printed to standard error.
