This chapter describes how to display system reports and user and system logs to evaluate performance or troubleshoot the system. It includes these sections:

Networking Reports

Optimization Reports

Data Store Reports

Branch Services Reports

Report Data

Topology

This section describes the report format, before describing individual reports.

The time-series reports are clear, interactive, and easy to navigate. The statistics presented in these reports format are readily accessible, and all updates to the report window appear in real time. This section describes the report format in detail.

The time-series report format not only makes data easily accessible, but also enhances your ability to explore data in context.

The plot area is where the data visualization occurs. Reports can display either a single-pane or dual-pane layout. In a dual-pane layout, both panes remain synchronized with respect to the x-axis. Each pane is capable of having two y-axes (a primary one on the left and a secondary one on the right).

The reports present the data series as simple line series graphs, but some reports display area series graphs where appropriate. The types of area series graphs are:

A tool tip displays the time stamp and the value of each data series at that time. The plot area colors the series names appropriately, and the data values have their associated units.

The plot area also displays subtle shading to denote work hours (white background) and nonwork hours (gray background). RiOS defines work hours as 8:00 AM to 5:00 PM on weekdays. You cannot configure the work hours.

The plot area reflects the changing chart window, as do the associated controls in the control panel.

Use the control panel to control how much data the chart displays, the chart properties, and whether to view or hide the summary statistics.

All three text fields validate your input; if you enter text in an invalid format, an error message appears. If you enter valid text that is logically invalid (for example, an end time that comes before the current start time), an error message appears. With all three text fields, if the focus leaves the field (either because you click outside the field or press Tab), the chart window updates immediately with the new value. Pressing Enter while in one of these fields has the same effect.

Below the chart window controls is an optional section of custom, report-specific controls. The custom controls vary for each report.

When you change the value of a custom control, the system sends a new request for data to the server. During this time, the control panel is unavailable and an updating message appears on the chart. When the report receives a response, the system replaces the chart, populates it with the new data, and makes the control panel available again.

The chart legend correlates the data series names with line colors and contains a few other features.

You can hide or show individual data series. When a white check box icon appears next to the data series name, you can hide the series from the plot area.

You cannot toggle the visibility of all the series, because it does not always make sense to hide a series (for example, if there is only one data series in the chart). For these series, a white check box does not appear next to the series name. You can hide the LAN Throughput and WAN Throughput series, but you cannot hide the Data Reduction series.

The legend also displays statistics. Each report defines any number of statistics for any of the data series in the chart. The system bases the statistics computation on the subset of each data series that is visible in the current chart window. The statistics display changes as the chart window changes. The reports also support nonseries statistics (for example, composite statistics that incorporate the data from multiple data series); these statistics appear at the bottom of the legend, below all the series.

Directly above the scroll bar is the navigator, that shows a much smaller and simpler display of the data in the plot area. The navigator displays only one data series.

Use the navigator to navigate the entire range of chart data. The scroll bar at the bottom shows you that portion of the total data range is displayed in the plot area.

The navigator display can appear very different from the plot area display when an interesting or eye-catching series in the plot area is not the series in the navigator.

The charts have a minimum chart window size of five minutes, so if you try to resize the chart window to something smaller, the chart window springs back to the minimum size.

You can also click the data display portion of the navigator (not the scroll bar) and the chart window moves to wherever you clicked.

You can change report default settings to match your preferred style. When you customize any report-specific settings, the system immediately writes them to disk on the SCC. The system saves all of your custom settings, even after you log out, clear your browsing history, or close the browser. When you view the report again, your custom settings are intact.

The system saves report settings on a per-user basis. A message appears at the top of each page when multiple users are logged in, explaining that user preferences can be overwritten.

The system also saves the chart window. Whenever you change the chart window, the next time you view any report, the chart window is set to the last chart window used.

Clear the browser cache and cookies after you upgrade to ensure the reports appear correctly.

The data grouping approach is used to plot graphs for report pages to increase the readability when there are too many data points.

Data grouping replaces a sequence of data points in a series with one grouped point. The values of each grouped point are calculated from the original values of every point used using the aggregation options, such as average, sum, or high (max). Therefore, when you move the cursor over a graph on a report page the data within the box is aggregated or grouped data for a certain period (or interval). As the zoom-level changes, the duration (or granularity) of the period (or interval) changes too.

The high-charts reports are configured to group samples to these granularities:

For high-charts select the appropriate granularity and group data based on the zoom-level.

When high-stock data grouping is active, the time displayed on a data point, when you move the mouse over, is start-time of the time range being grouped.

The data that the SCC collects at each hour is the data for the past hour where the values are for that period of time.

The grouping depends in the data that is plotted. The three groupings are: average, sum, and high (max).

Most of the graphs use average as their grouping function. These reports use other than average:

You can export statistics or schedule a time to export from of any individual report by scrolling to the lower part of the report page. You can also export statistics or schedule an export from the Reports > Report Data: Export page.
