This repository contains the common code for the Geophysical Monitoring System (GMS).
Source code is organized by language:
- Java code has been incorporated in the java subdirectory.
- Python code has been incorporated in the python subdirectory.
- Typescript code has been incorporated in the node subdirectory.
Instructions for building and running the system can be found here.
The GMS Station State-of-Health (SOH) Monitoring provides a suite of displays showing near real-time information about the state-of-health of individual stations and station groups in use on the System. These displays provide support monitoring, detecting, and troubleshooting problems with station data availability and quality.
Each station is given a status color (green = good SOH, yellow = marginal SOH, red = bad SOH) based on whether the data from that station meets configured thresholds over a configured period of time for characteristics such as data latency, amount of missing data, and environmental issues. SOH issues on individual channels roll up to provide an overall SOH status color for that station. Overview displays provide high-level monitoring and notification of issues while more detailed displays allow the user to drill-down into more in-depth information for troubleshooting.
