Utility qping is used to validate the runtime status of a Sun Grid Engine service daemon. The current Sun Grid Engine implementation allows one to query the SGE_QMASTER daemon and any running SGE_EXECD daemon. The qping command is used to send a SIM (Status Information Message) to the destination daemon.
The communication layer of the specified daemon will respond with a SIRM (Status Information Response Message) which contains status information about the consulted daemon.
The qping -dump and -dump_tag options allowing an administrator to observe the communication protocol data flow of a Sun Grid Engine service daemon. The qping -dump instruction must be started with root account and on the same host where the observed daemon is running.
qping mysite54 OGE 6.2u7 usage: qping [-help] [-noalias] [-ssl|-tcp] [ [ [-i
] [-info] [-f] ] | [ [-dump_tag tag [param] ] [-dump] [-nonewline] ] ] -i : set ping interval time -info : show full status information and exit -f : show full status information on each ping interval -noalias : ignore $SGE_ROOT/SGE_CELL/common/host_aliases file -ssl : use SSL framework -tcp : use TCP framework -dump : dump communication traffic (see "communication traffic output options" for additional information) (provides the same output like -dump_tag MSG) -dump_tag : dump communication traffic (see "communication traffic output options" for additional information) tag=ALL - show all tag=APP - show application messages tag=MSG - show commlib protocol messages - ERROR, WARNING, INFO, DEBUG or DPRINTF -nonewline : dump output will not have a linebreak within a message -help : show this info host : host name of running component port : port number of running component name : name of running component (e.g.: "qmaster" or "execd") id : id of running component (e.g.: 1 for daemons)
The default interval time is one second. Qping will send a SIM (Status Information Message) on each interval time.
The output is written to stdout. The environment variable "SGE_QPING_OUTPUT_FORMAT" can be set to hide columns, set a default column width or to set a hostname output format. The value of the environment variable can be set to any combination of the following specifiers separated by a space character:
"h:X" -> hide column X "s:X" -> show column X "w:X:Y" -> set width of column X to Y "hn:X" -> set hostname output parameter X. X values are "long" or "short"
