Alerts. Disruptive events that can result in loss of access to file system data. Examples are a segment
that is unavailable or a server that cannot be accessed.
Warnings. Potentially disruptive conditions where file system access is not lost, but if the situation is
not addressed, it can escalate to an alert condition. Examples are a very high server CPU utilization
level or a quota limit close to the maximum.
Information. Normal events that change the cluster. Examples are mounting a file system or creating
a segment.
Cluster Overview
The Cluster Overview provides the following information:
Capacity
The amount of cluster storage space that is currently free or in use.
Filesystems
The current health status of the file systems in the cluster. The overview reports the number of file
systems in each state (healthy, experiencing a warning, experiencing an alert, or unknown).
Segment Servers
The current health status of the file serving nodes in the cluster. The overview reports the number
of nodes in each state (healthy, experiencing a warning, experiencing an alert, or unknown).
Services
Whether the specified file system services are currently running:
One or more tasks are running.
No tasks are running.
Statistics
Historical performance graphs for the following items:
• Network I/O (MB/s)
• Disk I/O (MB/s)
• CPU usage (%)
• Memory usage (%)
On each graph, the X-axis represents time and the Y-axis represents performance.
Use the Statistics menu to select the servers to monitor (up to two), to change the maximum value
for the Y-axis, and to show or hide resource usage distribution for CPU and memory.
Recent Events
The most recent cluster events. Use the Recent Events menu to select the type of events to display.
You can also access certain menu items directly from the Cluster Overview. Mouse over the Capacity,
Filesystems or Segment Server indicators to see the available options.
Navigator
The Navigator appears on the left side of the window and displays the cluster hierarchy. You can
use the Navigator to drill down in the cluster configuration to add, view, or change cluster objects
such as file systems or storage, and to initiate or view tasks such as snapshots or replication. When
