gWLM offre due file delle proprietà che consentono di controllarne il comportamento. Un file serve per il daemon o servizio del server di amministrazione centrale, l’altro per tutti i nodi amministrati. Per informazioni sul comportamento da essi controllato, leggere questi file. Proprietà del server di amministrazione centrale |  |
Le proprietà del server di amministrazione centrale si trovano in /etc/opt/gwlm/conf/gwlmcms.properties in HP-UX ed in C:\Programmi\HP\Virtual Server Environment\conf\gwlmcms.properties in Windows. (Il percorso specificato per Windows è quello predefinito, tuttavia durante l'installazione potrebbe essere stato scelto un percorso differente.) In basso è mostrato il file gwlmcms.properties.  |

# This file contains the default configuration values for the

#
# You must restart gwlmcmsd for changes made to this file

#
# Set FileHandler log level for the following log files:
# /var/opt/gwlm/gwlmcmsd.log.0
# /var/opt/gwlm/gwlmcommand.log.0
# /var/opt/gwlm/gwlm.log.0
# /var/opt/vse/logs/gwlminitconfig.log.0
# 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

#
# Support for automatic database statistics gathering. These properties
# control how often row-level statistics are gathered from the database in
# order to optimize performance.
#
# com.hp.gwlm.cms.db.analyze.time:
# Frequency, in minutes, in which statistics are gathered. The
# default is to attempt to gather database statistics every 60
# minutes. When the analysis runs, statistics will only be gathered
# if a certain number of transactions have been processed (which is
# configured in the property below).
#
# com.hp.gwlm.cms.db.analyze.time:
# Number of consecutive transactions that must take place before a
# database analysis is performed.
#
com.hp.gwlm.cms.db.analyze.time = 60
com.hp.gwlm.cms.db.analyze.limit = 50
#
# Support for the database cache on the CMS.
#
# cachesize:
# The number of historical configurations to cache in memory.
# A larger historical configuration cache reduces time spent
# in database lookups. The valid range is 1-1000.
#
com.hp.gwlm.cms.cachesize = 100
#
# 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.util.Log.logFileSize = 20
com.hp.gwlm.ui.monitor.refresh = 15

Proprietà dell'agente |  |
Le proprietà dell'agente si trovano in /etc/opt/gwlm/conf/gwlmagent.properties in HP-UX ed in C:\Programmi\HP\Virtual Server Environment\conf\gwlmagent.properties in Windows. (Il percorso specificato per Windows è quello predefinito, tuttavia durante l'installazione potrebbe essere stato scelto un percorso differente.)  |  |  |  |  | NOTA: Affinché le modifiche a questo file abbiano effetto, è necessario riavviare il daemon gwlmagent in ogni nodo amministrato in cui sono state fatte. |  |  |  |  |

# This file contains the default configuration values for the

#
# Set FileHandler /var/opt/gwlm/gwlmagent.log.0 log level.

# 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

#
# 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.
#

#
# 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.

Porte di comunicazione |  |
Per le comunicazioni, gWLM utilizza le porte seguenti: Nodi amministrati: 9617 Server di amministrazione centrale: 9618 Se fosse necessario cambiare queste porte, aggiungere le righe seguenti: com.hp.gwlm.cms.port = porta_X com.hp.gwlm.node.port = porta_Y in entrambi i file delle proprietà:
gwlmcms.properties
In HP-UX, questo file si trova in /etc/opt/gwlm/conf/. In Windows, è in C:\Programmi\HP\Virtual Server Environment\conf\. (Il percorso specificato per Windows è quello predefinito, tuttavia durante l'installazione potrebbe essere stato scelto un percorso differente.)
/etc/opt/gwlm/conf/gwlmagent.properties
Il valore di porta_X e di porta_Y non può essere lo stesso. Il valore di porta_X della proprietà com.hp.gwlm.cms.port deve essere lo stesso in tutti i file delle proprietà, in tutti i nodi amministrati e nel server di amministrazione centrale. Analogamente, il valore di porta_Y della proprietà com.hp.gwlm.node.port deve essere lo stesso in tutti i file delle proprietà, in tutti i nodi amministrati e nel server di amministrazione centrale. Affinché le modifiche abbiano effetto, è necessario riavviare gwlmcmsd e gwlmagent. Se si usa gWLM tramite HP SIM, sarà necessario riavviare anche SIM. (In HP-UX, riavviare i daemon di SIM usando /opt/mx/bin/mxstop e mxstart. In Windows, riavviare il servizio HP Systems Insight Manager.)  |  |  |  |  | NOTA: Il riavvio di gwlmcmsd disattiverà temporaneamente HP Virtualization Manager e HP Capacity Advisor. |  |  |  |  |
