Monitoring performance of file systems

The File Systems page provides an easy way to monitor the performance, health status, and configuration aspects of the all available file systems in the ESS cluster.

The following options are available to analyze the file system performance:
  1. A quick view that gives the number of protocol nodes, NSD servers, and NSDs that are part of the available file systems that are mounted on the GUI server. It also provides overall capacity and total throughput details of these file systems. You can access this view by selecting the expand button that is placed next to the title of the page. You can close this view if not required.
    The graphs displayed in the quick view are refreshed regularly. The refresh intervals are depended on the displayed time frame as shown:
    • Every minute for the 5 minutes time frame
    • Every 15 minutes for the 1 hour time frame
    • Every six hours for the 24 hours time frame
    • Every two days for the 7 days time frame
    • Every seven days for the 30 days time frame
    • Every four months for the 365 days time frame
  2. A file systems table that displays many different performance metrics. To find file systems with extreme values, you can sort the values displayed in the file systems table by different performance metrics. Click the performance metric in the table header to sort the data based on that metric. You can select the time range that determines the averaging of the values that are displayed in the table and the time range of the charts in the overview from the time range selector, which is placed in the upper right corner. The metrics in the table do not update automatically. The refresh button at the top of the table allows to refresh the table with more recent data.
  3. A detailed view of the performance and health aspects of individual file systems. To see the detailed view, you can either double-click on the file system for which you need to view the details or select the file system and click View Details.
    The detailed performance view helps to drill-down to various performance aspects. The following list provides the performance details that can be obtained from each tab of the performance view:
    • Overview: Provides an overview of the file system, performance, and properties.
    • Events: System health events reported for the file system.
    • NSDs: Details of the NSDs that are part of the file system.
    • Pools: Details of the pools that are part of the file system.
    • Nodes: Details of the nodes on which the file system is mounted.
    • Filesets: Details of the filesets that are part of the file system.
    • NFS: Details of the NFS exports created in the file system.
    • SMB: Details of the SMB shares created in the file system.
