GoldenGate Service Monitor 0.1.0

ggsmon blog image

With the introduction of Oracle GoldenGate (Microservices), Oracle opened a lot of doors for people and organizations to create tools based off of the REST APIs.  Initially, the REST APIs within Oracle GoldenGate were developed to ease administration and configuration of the product.  This has allowed, RheoData to extend, build, and introduce GoldenGate Service Monitor.


The “GoldenGate Services (GGS) Monitor” is a Python script designed to monitor the status and lag of Oracle GoldenGate Extract and Replicat processes. It interacts with the GoldenGate Management REST API to fetch and display information about these processes, such as their status, lag, position, and last start time. The script presents this information in a tabular format on the terminal screen.


1. Python 3.x installed on your local machine.
2. The required Python packages should be installed. You can install them using `pip`:

pip install requests json dotenv
