Statistics

The Statistics page gives you a complete overview of your printing activity with key metrics, trends, and filament consumption over any time period.

Go to: https://localhost:3443/#statistics

Key metrics

At the top of the page, four KPI cards are shown:

Metric	Description
Success rate	Proportion of successful prints out of total prints
Total filament	Grams used in the selected period
Total print hours	Accumulated print time
Average print time	Median duration per print

Each metric shows the change from the previous period (↑ up / ↓ down) as a percentage deviation.

Success rate

The success rate is calculated per printer and overall:

• Successful — print completed without interruption
• Cancelled — manually stopped by user
• Failed — stopped by Print Guard, HMS error, or hardware fault

Click on the success rate chart to see which prints failed and the reason.

Improve success rate

Use Error Pattern Analysis to identify and fix the causes of failed prints.

Trends

The trend view shows development over time as a line chart:

1. Select Time period: Last 7 / 30 / 90 / 365 days
2. Select Grouping: Day / Week / Month
3. Select Metric: Number of prints / Hours / Grams / Success rate
4. Click Compare to overlay two metrics

The chart supports zoom (scroll) and panning (click and drag).

Filament consumption

Filament consumption is shown as:

• Bar chart — consumption per day/week/month
• Pie chart — breakdown between materials (PLA, PETG, ABS, etc.)
• Table — detailed list with total grams, meters, and cost per material

Consumption per printer

Use the multi-select filter at the top to:

• Show only one printer
• Compare two printers side by side
• See aggregated total for all printers

Activity calendar

View a compact GitHub-style heatmap directly on the statistics page (simplified view), or go to the full Activity Calendar for a more detailed view.

Export

1. Click Export statistics
2. Select date range and which metrics to include
3. Choose format: CSV (raw data), PDF (report), or JSON
4. The file is downloaded

The CSV export is compatible with Excel and Google Sheets for further analysis.

Comparison with previous period

Enable Show previous period to overlay graphs with the corresponding previous period:

• Last 30 days vs. the 30 days before
• Current month vs. previous month
• Current year vs. last year

This makes it easy to see whether you are printing more or less than before, and whether the success rate is improving.
