The main user interface navigation features give you the ability to edit the time range, effortlessly navigate between dashboards, and utilize other valuable tools. You can optimize your monitoring and analysis capabilities by utilizing these features.
Time Selector
Logically, one of the first things you will do when you access your Netskope “Advanced Diagnostics” environment is select the time range for which you want to analyze the data that has been collected.
The initial set of data you view, by default, covers the previous 24 hours.
On the upper left corner of your screen, the time range selection bar is always accessible.
It consists of four primary components.
Time Range Selection
To enter the setup menu, click on the main time selection button.
There are several options in the configuration menu.
Quick Time Range Selection
First, you can quickly set a time range from the dropdown list at the right side of the menu:
In the “Last” section, you can choose from the previous 1, 2, 6, 12, 24 hours, and the previous 3, 7, 14, and 31 days.
In this case, the time range for selected duration will be between now and past selected duration.
From the “Current” section, you can set the time for the current hour, day, week, or month.
This will pick the time from the beginning of the current hour, day, week, or month till now.
Finally, from the “Past” section, you can choose to view the most recent full hour, day, week, or month.
If you choose the past “Hour” at 9:30 a.m., for instance, the time range will be between 8:00 and 9:00 a.m. For the day, week, and month, the same principle applies.
Manual Time Range Selection
You have the option to manually select the time range you want to view data for.
You can select the beginning and ending dates of your choice from the calendar view.
In order to better suit their needs, advanced users can additionally manually update the “From” and “To” fields. You may enter “now-3d” as the start time and “now-1h” as the end time, for instance.
Timezone Selection
You can select the timezone to align with global corporate environments.
By default, the timezone is set to your local machine’s system setting.
Moving from a time range to the previous or next
The two buttons at the left side of the time selection bar allow you to quickly navigate from one time range to the previous or next one.
For example, if you initially selected the time range between 8:00am and 10:00am, when clicking on the previous button, you automatically transition to the time range from 6:00am to 8:00am. Clicking on the next button will transition to the next time range (10:00am to 12:00am in this example).
Retrieving the last time range selections
The “Recent time ranges used” button allows you to retrieve up to the last 6 time range selections, the most recent one being at the top of the list.
Auto-refresh
Depending on the selected time range, the data will be updated automatically according to the auto-refresh setting.
This default value is automatically set.
For example, when selecting the last hour, the auto-refresh will be triggered every minute. However, when selecting the last week, it is set to 1 hour by default.
Each refresh will update the time range (sliding window).
This auto-refresh can be manually configured from 1 minute to 1 hour.
It can also be switched off (select the option “off” from the dropdown list).
Navigation, Filters and Data Calculation
The very top of each dashboard provides some main navigation, filtering and data measurements features:
These main features are:
- When you navigate from one dashboard to another, the context of your investigation is kept in order to ease your troubleshooting process. It means that all filters defined on one dashboard are kept when navigating to the next one to drill down into more details. All consecutive dashboards are visible and can be accessed at any time.
However, when you have done your analysis, you may want to start a new one from scratch. This is where the three dots (1) are useful. By clicking on them you can reset the dashboards. - You’ll see one dedicated tab appearing for each dashboard you visit (2). You can close any of them by clicking on the cross (3).
- The “+” sign (4) lets you choose any dashboard you want to navigate to directly, without using the existing dashboard sections to navigate.
- By default, all metrics values are expressed in “average” (AVG). You can choose between AVG, P50 (Percentile 50), P75, P90 and P99 according to your analysis requirements and preferences (5).
- You can filter on multiple factors to focus on the data of interest to you. The main common filters are provided first, but the last “Filter” dropdown list lets you filter on some more advanced options (6).
Note that a filter in red identifies a filter that is normally used to get the most relevant data from the dashboard. The example above shows the “Site Details” dashboard, which is normally used when you have selected a specific site to focus your analysis on. However, this filter is not mandatory, so that more advanced users can use dashboards like “Site Details” to perform some comparison analysis between multiple sites.
Focus Mode
The focus mode is a key feature that will help you quickly focus on specific time periods directly from time series and distribution graphs widgets.
Typically, when a time series shows spikes, these are generally good indicators of temporary performance degradation. To focus your analysis on a spike, you can simply drag and drop directly in the graph to select the spike (1). You enter the focus mode, which means all data reported on the dashboard are now filtered on this specific time period, which is shown at the top (2).
You can then decide to temporarily analyze the data corresponding to the focus time while keeping all time series graphs showing the whole initial selected time period. Click anywhere outside of the time series focused area to remove this focus mode filter.
You can also decide to continue your analysis by selecting the focus mode time period as the new selected time period. All graphs and data will now take this new time period into account (the time series will zoom to this new time period). To do so, just click on the “Use as global range” button (3).
Bars and Sparkline Views
In table widgets, most of the column names are followed by a small icon.
This icon lets you choose between a “bars” representation and a “sparkline” representation.
The “bars” representation shows the value of the corresponding metric, according to the selected aggregation model:
The “sparkline” representation shows the evolution over time of the reported metric:
This sparkline view lets you detect any abnormal variations without having to navigate to other dashboards.
Multiple selections in tables
Some tables provide the possibility to filter the data corresponding to multiple lines through a checkbox selection (1).
Selecting a checkbox automatically creates the corresponding filter (2).
All data reported on the dashboard are now filtered. However, the table still shows you non filtered lines by default. It allows you to quickly change the filters according to your analysis requirements.
If you do not want to see the unselected lines in the table, just activate the “Show Only Filtered” option (3).
Expanding groups in a table
Some tables are grouping multiple object values in the same column.
In the following example, each line corresponds to a specific country.
As multiple Sites in a specific country can be connected to multiple Netskope POPs, these latter are being grouped by order of importance (see the column “POP”).
For example, sites in the USA are connected to US-SF01, US-SAN1, and so forth.
From this example, if you want to get the details for a particular country, simply click on the
