Simple dashboard to visualize ERDDAP usage metrics from log files

Simple ERDDAP Metrics

Simple ERDDAP Metrics is a lightweight tool to analyze ERDDAP server log files and visualize usage metrics through an interactive dashboard or export the parsed data as CSV.

Features

• Parse ERDDAP log files automatically
• Detect dataset views and downloads
• Track file formats used
• Aggregate usage statistics (daily, monthly, yearly)
• Optional IP geolocation
• Interactive dashboard
• CSV export via CLI
• User-configurable formats and endpoints via YAML configuration

[!IMPORTANT] This project is currently in beta and requires additional testing with large ERDDAP log archives.

Installation

The package can be installed with:

pip install simple-erddap-metrics

YAML Configuration File

Users can customize parsing behavior through a YAML configuration file.

Fields

• data_formats: Defines which file extensions count as downloads (e.g., .csv, .nc). If a request uses one of these formats, it is classified as a download.
• system_endpoints: Defines ERDDAP internal endpoints that should be ignored (e.g., index, documentation). These are not counted as dataset interactions.

Command Line Interface

The tool can be used either to launch the interactive dashboard or to export parsed logs to CSV.

Interactive dashboard mode

Launch the dashboard:

simple-erddap-metrics

This will start the Streamlit interface.

Export mode

Export parsed logs to CSV:

simple-erddap-metrics -e -l ./logs

This will generate the out.csv file.

CLI Arguments

Argument	Required	Description
-l, --logs	in export mode	Directory containing ERDDAP log files
-e, --export	optional	Export parsed logs to CSV
-c, --config	optional	YAML configuration file
--enable-geo	optional	Enable IP geolocation

Expected Log Files

The parser expects ERDDAP access logs such as:

log.txt
logArchivedAt...
logPreviousArchivedAt...

All files starting with log will be parsed.
