About data grouping
Reports use data grouping to improve readability when dealing with dense data. Grouping replaces multiple points with a single aggregated point using functions like average, sum, or maximum (high). The granularity of grouped data adapts based on zoom level. Supported granularities include 5, 10, 15, and 30 minutes, along with hourly intervals (1 to 12 hours) and 1-day increments. When grouping is active, mousing over a point displays the start time of the grouped interval and the aggregated value.
Each report uses grouping differently. For instance, the Bandwidth Optimization report uses sum for throughput and average for data reduction. The Optimized Throughput report uses average for general data and high for peak values. The Connection History report uses maximum for core metrics and average for others. Connection Pooling uses sum, while SnapMirror and SRDF reports use a combination of high and average functions based on series type.
About time intervals and data for specific times
Users can interact with data directly in the plot area. Mousing over reveals tooltips with timestamps, series names, and unit-based values. The chart also highlights work hours (8:00 AM to 5:00 PM weekdays) with a white background, while nonwork hours appear in gray. Zooming is accomplished by clicking and dragging across the plot area. The chart window and control panel update accordingly. To show or hide a data series, users can check or uncheck boxes next to series names. However, some series cannot be hidden (for example, Data Reduction) to preserve report integrity.
You can customize reports using a time interval of 1 hour (1h), 1 day (1d), 1 week (1w), 30 days (30d), yesterday, last week, or last month. Time intervals that don’t apply to a particular report are dimmed. For a custom time interval, enter the start time and end time using the format yyyy/mm/dd hh:mm:ss
Because the system aggregates data on the hour, request hourly time intervals. For example, setting a time interval to 08:30:00 to 09:30:00 from 2 days ago doesn’t create a data display, whereas setting a time interval to 08:00:00 to 09:00:00 from 2 days ago will display data.
When you request a custom time interval to view data beyond the aggregated granularity, the data isn’t visible because the system is no longer storing the data. For example, these custom time intervals don’t return data because the system automatically aggregates data older than seven days into two-hour data points:
• Setting a one-hour time period that occurred two weeks ago.
• Setting a 75-minute time period that occurred more than one week ago.
You can quickly see the newest data and see data points as they’re added to the chart dynamically. To display the newest data, click Show newest data.
About exporting reports
Reports can be exported via email, URL, or downloadable files. Users can choose formats such as HTML, PDF, or CSV. Per-appliance export options are available, with one CSV file generated per appliance if selected. Users can export immediately or schedule exports for future times and intervals. Printable views are accessible via a link at the bottom of the report page.
