  • In the Top 10 Host and Top 10 Storage dashlets, the bars for the write metrics do not display the value always due to restricted space. To view all the values on the graph, you can either hover the mouse over the bar or hide the read or the write bar using the legend at the bottom of the dashlet.

A warning message appears as HIGH NPU LOAD Detected on top of the Dashboard > SAN Insights window. The warning implies that one or more switches has an unacknowledged Syslog event during the previous week. The event may affect the availability of the analytics data stored or displayed. You must acknowledge these events to remove the warning.

  • Graph

  • Table

Graph

san-insight-graph

The graph is plotted with corresponding metrics with from and to date selected. It’s dynamic in nature as the data can be refreshed every 5 minutes and can be converted into a static graph using the pause button. Click Add Graph to create graph. You can add maximum of three graphs at a time on this page.

SAN Controller allows the user to view data for more than two weeks’ timeframe (up to a default maximum of 90 days. You can configure this timeframe in the server properties. Click drop down button next to Time Range and select date.

The Custom graphing metrics are enhanced to include the Write IO Failures, Read IO Failures, Write IO Aborts and Read IO Aborts to the drop-down metrics list.

ECT Baseline for each ITL Flow (Reads and Writes) is calculated using weighted average learned continuously over a training period:

  • The ECT Baseline computation consists of two parts: the training period and the recalibration time.

  • The training period for ECT Baseline is seven days by default (configurable).

  • After the training is completed, the ECT Baseline remains the same until the recalibration is triggered after 7 days by default (configurable).

  • By default every 14 days training runs for seven days (cyclic).

  • The percentage (%) deviation shows the deviation of the current normalized ECT compared to the ECT Baseline.

Table

When you select a failure or abort from Metrics drop-down list, the table list is filtered to show only the rows that have at least one of the selected failure or abort metrics as a nonzero entry. The table displays only 100 records. However, to help find their nonzero failures that you can filter the table to show the last 100 records with an Abort or Failure that is nonzero. When you select failure or aborts, the table label changes to depict this behavior.

To view, input any of the seven dimensions (Initiator Enc, Initiator, Target Enc, Target, LUN, Switch IP Address, Port, Timestamp, Read IOPs, Write IOPs) in the filter by attributes field (separated by comma), and select an associated metric.

Click Download button to download the table in .csv format. You can download the table of maximum 100 rows.
