Performance views
The Performance Dashboard provides the following metrics for the entire cluster:
• Cluster Report. Reports processor, memory, network, and filesystem metrics for
the entire cluster over the selected time period (the default is one hour).
• Physical View. Reports hardware configuration information.
• Filesystem Aggregate View. Reports total filesystem throughput and total filesystem
I/O operations for selected filesystems.
• Filesystem Detail View. Reports filesystem throughput and I/O operations data
for one filesystem. Data is reported for each node and the total is reported for
the entire cluster.
• Metrics View. Reports the selected metric across all nodes in the cluster.
Performance information is also available for individual nodes. Use the Grid menu
on any of the cluster views to select the node that you want to monitor, or click a
graph for that node. Only one node can be displayed at a time. If you need to
monitor multiple nodes, open a browser for each node.
The following information is available for individual cluster nodes:
• Host View. Reports uptime and CPU information and lists performance metrics
for the selected node.
• Node View. Reports hardware and software configuration information for the
selected node.
• Host-specific Filesystem View. Reports filesystem throughput and filesystem I/O
on the node for up to five PSFS filesystems.
The dashboard is updated every five minutes. You can also click Get Fresh Data to
update the display.
Display locations on the dashboard
The Performance Dashboard includes a locations feature that can be configured to
display the rack location of each node in the cluster. Following is an example. Rack
1 contains one node. The node is in the lowest position in the rack (rank 1). Rack
two includes two nodes, which are in the bottom two positions in the rack (rank 1
and rank 2).
