gWLM 提供的两个属性文件可以控制各种 gWLM 行为。其中一个文件用于 CMS 守护程序,另一个文件在所有受管节点中使用。查看这两个文件,可获得有关它们控制的行为的信息。

CMS 属性 (/etc/opt/gwlm/conf/gwlmcms.properties)

注释:在启动守护程序时,gWLM 仅读取一部分值;其他值将在部署 SRD 时读取。有关何时读取各个属性的信息,请参考该文件。

重新启动 gwlmcmsd 会暂时禁用 HP Integrity Essentials Virtualization Manager 和 HP Integrity Essentials Capacity Advisor。

gwlmcms.properties 文件如下所示。

#
# 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

代理属性 (/etc/opt/gwlm/conf/gwlmagent.properties)

注释:您必须在已修改属性文件的各个受管节点上重新启动 gwlmagent 守护程序,才能使对该文件的更改生效。

gwlmagent.properties 文件如下所示。

#
# 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

#       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

通信端口

gWLM 使用下列通信端口:

受管节点:9617

CMS:9618

如果需要更改这些端口,请将下列行:

com.hp.gwlm.cms.port = 端口 X

com.hp.gwlm.node.port = 端口 Y

添加到下面两个属性文件:

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

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

其中端口 X端口 Y 的值不能相同。

在所有受管节点以及 CMS 上的所有属性文件中,com.hp.gwlm.cms.port 属性必须具有相同的端口 X 值。同样,在所有受管节点以及 CMS 上的所有属性文件中,com.hp.gwlm.node.port 属性必须具有相同的端口 Y 值。

必须重新启动 gwlmcmsdgwlmagent,才能使更改生效。如果通过 HP Systems Insight Manager (SIM) 使用 gWLM,还必须停止 (/opt/mx/bin/mxstop) 并重新启动 (mxstart) SIM。

注释:重新启动 gwlmcmsd 会暂时禁用 HP Integrity Essentials Virtualization Manager 和 HP Integrity Essentials Capacity Advisor。
