gWLM proporciona dos archivos de propiedades que le permiten controlar diversos comportamientos de gWLM. Un archivo es para el demonio CMS y el otro es para utilizarlo en todos los nodos administrados. Lea los archivos para obtener información sobre los comportamientos que controlan.

Propiedades del servidor CMS (/etc/opt/gwlm/conf/gwlmcms.properties)

NOTA: gWLM lee algunos valores sólo cuando se inicia un demonio, mientras que otros valores se leen cuando se despliega un dominio de recursos compartidos. Consulte el archivo para obtener información sobre cuándo se leen las propiedades individuales.

El reinicio de gwlmcmsd deshabilita temporalmente HP Integrity Essentials Virtualization Manager y HP Integrity Essentials Capacity Advisor.

El archivo gwlmcms.properties se muestra más adelante.

# Contents:
#       This file contains the default configuration values for the
#       Global Workload Manager CMS.
#
#       You must restart gwlmcmsd for changes made to this file
#       to take effect--unless otherwise noted.
#

#
# Set FileHandler /var/opt/gwlm/gwlmcmsd.log.0 log level.
# Valid levels, from most severe to least, are:
#       SEVERE
#       WARNING
#       INFO
#       CONFIG
#       FINE
#       FINER
#       FINEST
# When you set the level, you will see messages only from that level and
# the levels that are more severe. So, the SEVERE level produces the fewest
# messages, while the FINEST level includes messages from all seven levels.
#
com.hp.gwlm.util.Log.logLevel = INFO

#
# Turn on/off ConsoleHandler. ConsoleHandler uses the same log
# level as defined for FileHandler /var/opt/gwlm/gwlmcmsd.log.0.
#
com.hp.gwlm.util.Log.ConsoleHandler = off

#
# Support for the database cache on the CMS.
#
#   cachesize:
#       The number of database objects that should be cached in memory
#       in order to reduce the number of round-trip operations.
#       If you set this property to a value that is too low, gWLM will
#       use a default value of 4096.
#
com.hp.gwlm.cms.cachesize = 100000

#
# Support for local data caching on a remote node for report generation.
# These properties are defined on the CMS but are pushed out to the remote
# node managers during deployment of an SRD.  The cached objects on the
# agent consume an amount of memory approximated by:
#
#    Memory = 5000 * workloads * cachesize * (60 / resource_domain_interval)
#
# bytes of memory.  For example, if there are 4 workloads deployed with a
# 15 second interval and a cachesize of 20 minutes, the agent will need:
#
#    Memory = 5000 * 4 * 20 * (60 / 15) ~ 2.5 MB.
#
#   cachesize:
#       The number of minutes of real-time data to maintain on the remote
#       node for future CMS access.  This value must be at least three
#       times the ‘samples’ value specified below.  The default value is
#       20 minutes.
#
#   samples:
#       The number of minutes of real-time data used to aggregate into a
#       historical data point. The default is to aggregate the data into
#       5-minute averages.
#
com.hp.gwlm.node.cachesize = 20
com.hp.gwlm.node.samples   = 5

#
# Support for real-time graphing properties.
#
#   viewport:
#       The size of the displayed real-time graph (in minutes).
#
#   refresh:
#       The refresh rate of the real-time graphs and tables (in seconds).
#
com.hp.gwlm.ui.monitor.viewport = 20
com.hp.gwlm.ui.monitor.refresh  = 15

Propiedades del agente (/etc/opt/gwlm/conf/gwlmagent.properties)

NOTA: El demonio gwlmagent debe reiniciarse en cada nodo administrado donde haya modificado el archivo de propiedades para que surtan efecto los cambios en el archivo.

El archivo gwlmagent.properties se muestra más adelante.

# Contents:
#       This file contains the default configuration values for the
#       Global Workload Manager Agent on a given managed node. The
#       agent on each managed node uses the default values unless you
#       edit that node’s gwlmagent.properties file.
#
#       You must restart gwlmagent for changes made to this file to
#       take effect.
#

#
# Set FileHandler /var/opt/gwlm/gwlmagent.log.0 log level.
# Valid levels, from most severe to least, are:
#       SEVERE
#       WARNING
#       INFO
#       CONFIG
#       FINE
#       FINER
#       FINEST
# When you set the level, you will see messages only from that level and
# the levels that are more severe. So, the SEVERE level produces the fewest
# messages, while the FINEST level includes messages from all seven levels.
#
com.hp.gwlm.util.Log.logLevel = INFO

#
# Specify the size (in MB) and number of files to use  
# for logging. For a single file of unlimited size, set
# logFileSize to negative one (logFileSize=-1).
# Otherwise, total log file size is
#    logFileSize * logNFiles
#
com.hp.gwlm.util.Log.logFileSize = 20
com.hp.gwlm.util.Log.logNFiles = 3

#
# Turn on/off ConsoleHandler. ConsoleHandler uses the same log
# level as defined for FileHandler /var/opt/gwlm/gwlmagent.log.0.
#
com.hp.gwlm.util.Log.ConsoleHandler = off

#
# Set the number of seconds for the high availability (HA) minimum
# timeout. Communication is considered lost on a managed node
# once the timeout period has elapsed.
#
# By default, communication is not considered lost until 10 allocation
# intervals have elapsed without communication. The default value of the
# property (60) is used only when the allocation interval is less than 6
# seconds.  
#
com.hp.gwlm.node.HA.minimumTimeout = 60

#
# Enable/disable use of Instant Capacity (iCAP) to simulate movement of
# cores across nPartitions. To use iCAP, you must enable this property on 
# each managed nPartition where you want to take advantage of iCAP. Also, 
# each nPartition must meet the requirements outlined in the online help 
# topic "Getting the most out of gWLM" as well as in the section "USING 
# NPARS AS COMPARTMENTS IN AN SRD" in the gwlmxml(4) man page on HP-UX or 
# the gwlmxml(5) man page on Linux.
#
com.hp.gwlm.platform.icap.manageWithIcap = on

#
# Set the minimum number of Temporary Instant Capacity (TiCAP) minutes
# that must be available for TiCAP activation.  gWLM will stop using
# TiCAP when the available balance goes below this threshold.  The
# same value should be set on all agents managing the SRD.  To use
# TiCAP, it must be available on the complex and enabled at the policy
# level or the SRD level.
#
com.hp.gwlm.node.ticap.minimumBalance = 30

Puertos de comunicaciones

gWLM utiliza los siguientes puertos de comunicaciones:

Nodos administrados: 9617

CMS: 9618

Si tiene que cambiar estos puertos, agregue las siguientes líneas:

com.hp.gwlm.cms.port = puertoX

com.hp.gwlm.node.port = puertoY

en ambos archivos de propiedades.

/etc/opt/gwlm/conf/gwlmcms.properties

/etc/opt/gwlm/conf/gwlmagent.properties

Los valores puertoX y puertoY no pueden ser iguales.

La propiedad com.hp.gwlm.cms.port debe tener el mismo valor puertoX en todos los archivos de propiedades: en todos los nodos administrados y en el servidor CMS. De igual modo, la propiedad com.hp.gwlm.node.port debe tener el mismo valor puertoY en todos los archivos de propiedades: en todos los nodos administrados y en el servidor CMS.

gwlmcmsd y gwlmagent deben reiniciarse para que los cambios surtan efecto. Si utiliza gWLM a través del administrador HP Systems Insight Manager (SIM), también deberá detener (/opt/mx/bin/mxstop) y reiniciar (mxstart) el SIM.

NOTA: El reinicio de gwlmcmsd deshabilita temporalmente HP Integrity Essentials Virtualization Manager y HP Integrity Essentials Capacity Advisor.
