6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

10 Using the Statistics tool
The Statistics tool reports historical performance data for the cluster or for an individual file serving
node. You can view data for the network, the operating system, and the file systems, including the
data for NFS, memory, and block devices. Statistical data is transmitted from each file serving
node to the Fusion Manager, which controls processing and report generation.
Installing and configuring the Statistics tool
The Statistics tool has two main processes:
• Manager process. This process runs on the active Fusion Manager. It collects and aggregates
cluster-wide statistics from file serving nodes running the Agent process, and also collects local
statistics. The Manager generates reports based on the aggregated statistics and collects
reports from all file serving nodes. The Manager also controls starting and stopping the Agent
process.
• Agent process. This process runs on the file serving nodes. It collects and aggregates statistics
on the local system and generates reports from those statistics.
IMPORTANT: The Statistics tool uses remote file copy (rsync) to move statistics data from the
file serving nodes to the Fusion Manager for processing, report generation, and display. SSH keys
are configured automatically across all the file serving nodes to the active Fusion Manager.
Installing the Statistics tool
The Statistics tool is installed automatically when the StoreAll software is installed on the file serving
nodes. To install or reinstall the Statistics tool manually, use the following command:
ibrixinit -tt
Note the following:
• Installation logs are located at /tmp/stats-install.log.
• By default, installing the Statistics tool does not start the Statistics tool processes. See
“Controlling Statistics tool processes” (page 104) for information about starting and stopping
the processes.
• If the Fusion Manager deamon is not running during the installation, Statstool is installed as
passive. When Fusion Manager acquires an active/passive state, the Statstool management
console automatically changes according to the state of Fusion Manager.
Enabling collection and synchronization
To enable collection and synchronization, configure synchronization between nodes. Run the
following command on the active Fusion Manager node, specifying the node names of all file
serving nodes:
/usr/local/ibrix/stats/bin/stmanage setrsync <node1_name> ...
<nodeN_name>
For example:
# /usr/local/ibrix/stats/bin/stmanage setrsync ibr-3-31-1 ibr-3-31-2
ibr-3-31-3
NOTE: Do not run the command on individual nodes. All nodes must be specified in the same
command and can be specified in any order. Be sure to use node names, not IP addresses.
To test the rsync mechanism, see “Testing access” (page 105).
