6.2 HP IBRIX 9300/9320 Storage Administrator Guide (AW549-96049, December 2012)

Updating the Statistics tool configuration
When you first configure the Statistics tool, the configuration includes information for all file systems
configured on the cluster. If you add a new node or a new file system, or make other additions to
the cluster, you must update the Statistics tool configuration. Complete the following steps:
1. If you are adding a new file serving node to the cluster, enable synchronization for the node.
See “Enabling collection and synchronization” (page 81) for more information.
2. Add the file system to the Statistics tool. Run the following command on the node hosting the
active Fusion Manager:
/usr/local/ibrix/stats/bin/stmanage loadfm
The new configuration is updated automatically on the other nodes in the cluster. You do not
need to restart the collection process; collection continues automatically.
Changing the Statistics tool configuration
You can change the configuration only on the management node. To change the configuration,
add a configuration parameter and its value to the /etc/ibrix/stats.conf file on the currently
active node. Do not modify the /etc/ibrix/statstool.conf and /etc/ibrix/
statstool.local.conf files directly.
You can set the following parameters to specify the number of reports that are retained.
Default Retention PeriodReport Type to retainParameter
1 dayHourly reportage.report.hourly
7 daysDaily reportage.report.daily
14 daysWeekly reportage.report.weekly
7 daysUser-generated reportage.report.other
For example, for daily reports, the default of 7 days saves seven reports. To save only three daily
reports, set the age.report.daily parameter to 3 days:
age.report.daily=3d
NOTE: You do not need to restart processes after changing the configuration. The updated
configuration is collected automatically.
Fusion Manager failover and the Statistics tool configuration
In a High Availability environment, the Statistics tool fails over automatically when the Fusion
Manager fails over. You do not need to take any steps to perform the failover. The statistics
configuration changes automatically as the Fusion Manager configuration changes.
The following actions occur after a successful failover:
• If Statstool processes were running before the failover, they are restarted. If the processes
were not running, they are not restarted.
• The Statstool passive management console is installed on the IBRIX Fusion Manager in
maintenance mode.
• Setrsync is run automatically on all cluster nodes from the current active Fusion Manager.
• Loadfm is run automatically to present all file system data in the cluster to the active Fusion
Manager.
• The stored cluster-level database generated before the Fusion Manager failover is moved to
the current active Fusion Manager, allowing you to request reports for the specified range if
pre-generated reports are not available under the Hourly, Daily and Weekly categories. See
“Generating reports” (page 83).
