Overview
The Daily Statistics screen provides a heatmap of operational status by date for a given year and allows users to select a specific date to analyze collection, alarm, communication, equipment, Edge, and flow indicators on a single screen.
Path: Left Menu > Overview > Statistics (Internal URL /statistics/index)
The current screen title is displayed as 통계 · YYYY-MM-DD (어제). Since the statistics aggregation is based on the previous day's data, the reference date is set to yesterday upon entry.

Top Header and Year Search
| Control | Description |
|---|---|
| Year Selector | Select the year to view statistics. Default is the current year |
| Search | Reloads the heatmap and statistics data for the selected year |
You must click the Search button after changing the year to refresh the screen.
Annual System Availability Heatmap
The heatmap displays the system availability for each day of the selected year.
| Item | Description |
|---|---|
| Chart ID | heatmap_chart |
| Panel Title | Annual System Availability |
| Display Unit | 1 day = 1 cell |
| Action | Clicking a cell refreshes the detailed charts below based on the selected day |
Sections with dark and stable colors are likely operating normally. For days with faint or empty colors, check for collection failures, faults, or missing aggregations.
Selected Day KPI Cards
When a date is selected from the heatmap, 8 KPI cards are updated based on the selected day.
| Card | Meaning |
|---|---|
| System Availability | Ratio of normal operation over 24 hours |
| DB Storage Capacity | Time series and event repository capacity |
| Communication | Number of normal OPCs and overall communication status |
| Diagnostic Warning/Error | Selected day diagnostic WARN/ERROR load |
| Total Data Collection | Number of collection points on the selected day |
| Total Alarm Count | Total alarms on the selected day. Open occurrences are not counted if hidden, suppressed, or excluded from service |
| BLOB Upload | Number of file uploads on the selected day |
| Site / Tag / Equipment | Model scale and registration status |
Each card displays the delta compared to the previous day. For collection volume and availability, a decrease is a danger signal; for alarms and diagnostics, an increase is a danger signal.
Selected Day Detailed Charts
The following guidance is displayed before a date is clicked.
히트맵에서 날짜를 선택해주세요.
When a date is clicked, the detailed area expands and charts are displayed in the following order:
- Point, Alarm, Latency, and Validation Failure (4 charts)
- Asset, OPC, Site, and Tag (16 charts)
- Edge (4 charts)
- Flow (4 charts)
Point, Alarm, and Latency Trends
| Panel | Chart ID | Purpose |
|---|---|---|
| Point Reception Trend | report_point_chart | Point reception volume by time of day |
| Alarm Priority Trend | report_alarm_chart | Changes in Info, Warning, and Critical alarms by time of day |
| Average Latency Trend | report_latency_chart | Average delay from collection to storage |
| Point Validation Failure Trend | trend_point_fail_chart | Type, range, and validity verification failures |
If the time period with a drop in collection volume overlaps with a rise in alarms or latency, check for connection, Edge, or storage bottlenecks.

| Top 10 Alarms by Tag | report_tag_alarm_chart | Tags with the most alarms |
| Alarm Distribution by Site | site_alarm_chart | Proportion of alarms by site |
| Equipment Connection Status Distribution | asset_connection_chart | Equipment connection status distribution |
| Collection Distribution by Data Type | report_datatype_pie_chart | Collection proportion by type |
| Average Latency by OPC | report_opc_latency_chart | Identification of OPCs with high latency |
| Alarm Comparison by Site | report_asset_top_alarm_chart | Alarm ranking by site |
| Data Collection Distribution by Site | site_data_chart | Collection proportion by site |
| OPC Communication Connection Status Trend | trend_opc_conn_chart | Changes in OPC status by time of day |
| OPC Communication Latency Trend | trend_opc_latency_chart | Communication latency by time of day |

FAQ
Q. I selected a date, but the detailed charts are empty.
A. There may be no collection data for that date, or aggregation may not yet be complete. Please verify actual data ingress in Connection Status and Data Point.
Q. I cannot see the site summary table that was there before.
A. The statistics screen has been reorganized to focus on the heatmap, KPI cards, and chart grids. For site-specific comparisons, use charts 사이트별 데이터 수집 비교, 사이트별 알람 비교, and 사이트별 데이터 수집 분포.
Q. There is no system reference tab.
A. The current screen expands detailed charts in a single flow without separate tabs. System health can be checked through KPI cards, point/alarm trends, and the System screen.
Q. Why are flow charts in the statistics screen?
A. Flow execution volume and errors are operational indicators of data processing automation status. They are useful for verifying if data collection anomalies and automation failures overlap in the same time period.
