Statistics Interface Guide

This guide explains how to navigate and use NetFUNNEL's Statistics interface, including screen layout, UI elements, filtering options, and data export capabilities. For detailed explanations of what each metric means and how to interpret them, see the Metrics Quick Reference documentation.

Timezone

On-premise versions do not support timezone changes. All time information is displayed in UTC+9 (Korea Standard Time) by default.

Overview

The Statistics interface provides historical data analysis capabilities that complement real-time monitoring. Query historical data by day/month/year periods, view trends through interactive charts, and export data as CSV for further analysis.

The Statistics page consists of three main sections:

1. Project Section: Metrics aggregated at the project level, useful for project administrators
2. NetFUNNEL Section: Metrics at the NetFUNNEL server instance level, useful for server administrators
3. Segment Section: Metrics at the segment level, useful for segment administrators

Each section provides filtering options, interactive charts, and CSV export functionality.

Data Refresh Requirement

All statistics data is NOT updated in real-time. You must click the Search button to refresh or display data. Simply selecting filters or time periods will not update the charts automatically.

Time Filter

The time filter allows you to select the time period for historical data analysis.

Available Options:

• Day: Select a single day for analysis (24 hours)
• Month: Select a date range in month units (from month X to month Y)
• Year: Select a date range in year units (from year X to year Y)

Chart Resolution by Time Period:

• Day view: 1-minute resolution (data points every minute)
• Month view: 1-hour resolution (data points every hour)
• Year view: 1-day resolution (data points every day)

How to Use:

1. Select Time Period Mode: Click on the time filter dropdown and select Day, Month, or Year to choose how you want to select the time period.

2. Select Date Range: Click on the date range display area (shown as yyyy.mm.dd ~ yyyy.mm.dd format) next to the time filter. A calendar will appear for date selection.

   Date Selection Behavior by Mode:

   • Day mode: You can select only a single day (one day only)
   • Month mode: You can select a date range in month units (e.g., from January to March)
   • Year mode: You can select a date range in year units (e.g., from 2023 to 2024)

3. Click Search Button: After selecting the date range, click the Search button to query and display the data for the selected period.

Search Button Required

Important: Selecting a time period and date range alone will NOT update the charts. You must click the Search button after selecting the time period and date range to query and display the data.

Time Period Selection

• Day view: Best for detailed minute-by-minute analysis and short-term trends (1-minute resolution). Select a single day.
• Month view: Best for weekly patterns and medium-term analysis (1-hour resolution). Select a date range in month units.
• Year view: Best for long-term trends and seasonal patterns (1-day resolution). Select a date range in year units.

Project Section

2. Use Element Selection Filter: Optionally use the element selection filter (search box) to limit or search through available project options (see Selecting Chart Elements in Common Operations)
3. Select Metrics: Choose which metrics to display in the charts using the metric dropdown
4. Click Search Button: Click the Search button to refresh and display data for the selected projects
5. View Charts: Charts will display data only for the checked projects

Common Operations

Filtering Data

Each section provides filtering options to focus on specific data:

1. Time Period: Use the global time filter to select Day/Month/Year view
2. Select Elements: Use checkboxes in each section's Filter Area to select which projects, segments, or server instances to display
3. Element Selection Filter: Optionally use the element selection filter (search box) to search and filter the options shown in the Filter Area (see Selecting Chart Elements)
4. Search Button: Click the Search button to refresh and display data after selecting any filters

Search Button Required

Important: Selecting filters alone will NOT update the charts. You must click the Search button after selecting:

• Time period filters
• Elements in Filter Area (projects, segments, server instances)
• Any filter that affects chart output

Charts will only refresh and display data after clicking the Search button.

Selecting Chart Elements

All sections (Project, Segment, and NetFUNNEL) include an element selection filter (search box) that allows you to search and filter the options shown in the Filter Area. This helps you quickly find specific elements when you have many options.

How to Use:

1. Type in the element selection filter (search box) to search for specific elements
2. The Filter Area will show only the elements matching your search
3. Check the boxes in the Filter Area for the elements you want to display in charts
4. Click the Search button to refresh and display data for the selected elements

Viewing Charts

Charts provide interactive visualizations of historical data:

1. Hover: Hover over data points to see exact values at specific times
2. Compare: Display multiple segments simultaneously for comparison

Exporting Data

CSV export is available in all sections (Project, Segment, and NetFUNNEL). Each section has its own CSV button that downloads data for the selected elements in that section.

How to Export:

1. Select elements using checkboxes in the Filter Area
2. Click the CSV button in the section header
3. The CSV file automatically downloads to your browser's download folder

The CSV contains all data points displayed in the chart area for the selected elements and time period, formatted as a table with timestamps and metric values.
