Overview
The Daily Statistics screen shows the day-by-day operating status of a year as a heatmap, and lets you select a specific date to analyze that day's collection, alarm, communication, equipment, Edge, and flow metrics on a single screen.
Path: Left menu > Overview > Daily Statistics (internal URL /statistics/index)
The current screen title is displayed in the form 통계 · YYYY-MM-DD (어제). Because statistics are aggregated on the previous day's data, the reference date shown on entry is yesterday.

| Area | Displays |
|---|---|
| Top header | Screen title, year selector, lookup button |
| Heatmap | Annual system availability. Clicking a cell loads the selected day's details |
| KPI cards | 8 key metrics for the selected day with day-over-day deltas |
| Detail charts | Point/alarm, asset/OPC, Edge, and flow charts |
Top Header and Year Lookup
| Control | Description |
|---|---|
| Year selector | Selects the year to look up statistics for. Defaults to the current year |
| Lookup | Reloads the heatmap and statistics data for the selected year. |
After changing the year, you must click the Lookup button for the screen to refresh.
Annual System Availability Heatmap
The heatmap displays the system availability for each date of the selected year, one cell at a time.
| Item | Description |
|---|---|
| Chart ID | heatmap_chart |
| Panel title | Annual System Availability |
| Display unit | 1 day = 1 cell |
| Behavior | Clicking a cell refreshes the detail charts below for the selected day |
Sections with dark, stable colors are likely normal operating days. For days with faint or empty coloring, check for missing collection, faults, or aggregation gaps.
Selected-Day KPI Cards
When you select a date in the heatmap, the 8 KPI cards refresh for that day.
| Card | Meaning |
|---|---|
| System availability | Share of the 24 hours in normal operation |
| DB storage capacity | Capacity of the time series and event stores |
| Communication | Number of healthy OPC connections and overall communication status |
| Diagnostic warnings/errors | WARN/ERROR diagnostic load for the selected day |
| Total data collection | Number of points collected on the selected day |
| Total alarm count | Total alarm volume for the selected day |
| BLOB uploads | Number of file uploads on the selected day |
| Sites / tags / equipment | Model scale and registration status |
Each card also shows the day-over-day delta. For collection volume and availability, a decrease is the warning sign; for alarms and diagnostics, an increase is.
Selected-Day Detail Charts
Before you click a date, the following guidance is displayed.
히트맵에서 날짜를 선택해주세요.
When you click a date, the detail area expands and charts appear in the following order.
- 4 charts for points, alarms, latency, and validation failures
- 16 charts for assets, OPC, sites, and tags
- 4 Edge charts
- 4 flow charts
Point, Alarm, and Latency Trends
| Panel | Chart ID | Purpose |
|---|---|---|
| Point reception trend | report_point_chart | Point reception volume by hour |
| Alarm trend by priority | report_alarm_chart | Hourly changes in info, warning, and critical alarms |
| Average latency trend | report_latency_chart | Average delay from collection to storage |
| Point validation failure trend | trend_point_fail_chart | Type, range, and validity check failures |
If the hours with reduced collection volume overlap with the hours where alarms and latency rise, examine connection, Edge, and storage bottlenecks together.
Asset, OPC, Site, and Tag Charts
| Panel | Chart ID | Purpose |
|---|---|---|
| OPC communication connection status distribution | opc_status_chart | OPC status distribution for the selected day |
| Equipment health status distribution | asset_health_chart | Equipment health status distribution |
| Data collection comparison by site | report_asset_top_chart | Collection volume ranking by site |
| Top 10 tags by point reception | report_tag_point_chart | Tags with the highest reception volume |
| Top 10 tags by alarms | report_tag_alarm_chart | Tags with the most alarms |
| Alarm distribution by site | site_alarm_chart | Alarm share by site |
| Equipment connection status distribution | asset_connection_chart | Equipment connection status distribution |
| Collection distribution by data type | report_datatype_pie_chart | Collection share by type |
| Average latency by OPC | report_opc_latency_chart | Identifies OPC connections with high delay |
| Alarm comparison by site | report_asset_top_alarm_chart | Alarm ranking by site |
| Data collection distribution by site | site_data_chart | Collection share by site |
| OPC communication connection status trend | trend_opc_conn_chart | Hourly changes in OPC status |
| OPC communication delay trend | trend_opc_latency_chart | Communication delay by hour |
| OPC latency histogram | opc_latency_chart | Delay distribution |
| Data collection by line | report_line_point_chart | Collection volume comparison by line |
| Health and connection status by zone | report_area_status_chart | Status comparison at the zone level |
Edge and Flow Charts
4 Edge Charts
| Panel | Chart ID | Purpose |
|---|---|---|
| Edge health by hour | edge_health_hour_chart | Hourly trend of Edge health status |
| Edge API calls | edge_stats_rest_chart | Load from server-to-Edge calls |
| Edge push reception | edge_stats_push_chart | Reception load from Edge-to-server pushes |
| Edge health distribution | edge_stats_health_chart | Edge health status distribution |
4 Flow Charts
| Panel | Chart ID | Purpose |
|---|---|---|
| Top 5 flows by calls | flow_top_called_chart | Flows with the highest call volume |
| Top 5 flows by errors | flow_top_errored_chart | Flows with the most errors |
| Flow trend by hour | flow_hour_trend_chart | 24-hour completion/error flow for the selected day |
| Flow trend by day | flow_daily_trend_chart | Completion/error flow over the last 30 days |
Response by Abnormal Signal
| Symptom | Check first | Follow-up action |
|---|---|---|
| Sharp drop in availability | Heatmap colors, system availability card | Check System and Diagnostics logs |
| Sharp drop in total data collection | Point reception trend, data collection comparison by site | Check Connection status, Edge |
| Surge in alarms | Alarm trend by priority, top tags by alarms | Review details by tag and site in Alarms |
| Increased latency | Average latency, average latency by OPC | Separate network, Edge, and storage delay |
| Increased validation failures | Point validation failure trend | Check tag data type, range, and collected values |
| Increased flow errors | Top 5 flows by errors | Check Flow execution history |
Frequently Asked Questions
Q. I selected a date, but the detail charts are empty.
A. There may be no collected data for that date, or aggregation may not be complete yet. Check whether data is actually arriving in Connection status and Data Points.
Q. The site-wide summary table I used to see is no longer on the screen.
A. The statistics screen has been redesigned around the heatmap, KPI cards, and chart grid. For site comparison, use the 사이트별 데이터 수집 비교, 사이트별 알람 비교, and 사이트별 데이터 수집 분포 charts.
Q. There is no system-level tab.
A. The current screen expands the detail charts in a single flow with no separate tabs. Check the system's own status using the KPI cards, the point and alarm trends, and the System screen.
Q. Why are flow charts on the statistics screen?
A. Flow execution volume and errors are operational indicators of the state of data processing automation. They are useful for checking whether collection anomalies and automation failures overlap in the same time window.
