    Performance metrics for SMB

    View historical performance metrics

    Procedure
    1. Under System, select Performance.
    2. Select the historical metrics dashboard for the system for which you created a performance metrics display.
    3. For each system dashboard, you can define the time range of the values displayed for all the metric line charts on that dashboard. The default time range is Last 1 hour. Alternatively, select one of the other time range values.
      The time range selections are enabled only if Unisphere has data spanning that time range.
    4. For a custom time range, select Custom and choose the start and end dates and times of the charts displayed. Click OK.
    5. To drill down into the data displayed in the line chart, you can breakdown the data displayed into individual lines that show the categories and contributors that provide data to the performance metric. Choose among the breakdown categories available for a particular metric.
      Each contributor displays as a different color line in the chart and is identified in the legend. You can quickly remove and add each contributor by clicking on its name in the legend. Use the breakdown display to determine if one contributor is adding to the aggregated total more than another contributor as well as analyze how a contributor's activity increases or decreases at a particular time.
    6. Hover over a data point in the chart to display the date, time, and measurement associated with that data point. Gaps in metric data collection are displayed as gaps in the line chart.

    CIFS Bandwidth

    Total amount of CIFS (SMB) I/O requests, in KB/s, across all ports in the storage system.

    Breakdown and filter categories

    The aggregated data can be broken down or filtered by the following categories:

    This category...
    Groups or filters data by the...
    Storage Processor
    SPs that processed the network traffic.
    Read/Write
    Traffic types: read I/O and write I/O.

    CIFS I/O Size

    Average size of CIFS (SMB) I/O requests, in KB, across all ports in the storage system. Calculated as a weighted average, which gives more weight to the SP with the highest number of CIFS I/O requests.

    CIFS Response Time

    Average time spent completing CIFS I/O requests, in microseconds, across all file systems in the storage system. Calculated as a weighted average, which gives more weight to the file systems with the highest number of I/O requests.
