Transaction Log

Txlog Architecture Overview ​

I've designed Txlog around two main parts that work together to keep your package transactions organized. Have you ever wondered where all those DNF logs actually go? Well, that's exactly what we're solving here.

Server Version ​

The server is the brain of the operation. It manages our PostgreSQL database and acts as a central hub for all the data coming in from across your network. I've built it to handle multiple agent instances at once without breaking a sweat, ensuring every piece of transaction data finds its home.

If you're ready to get things running, you should check out the Server Installation and Configuration guide.

Agent Version ​

On the other side, we have the agent. It's a lightweight little piece of software that lives on your RHEL-compatible workstations. Its job is simple: keep an eye on DNF, grab the transaction data, and send it over to the server securely. We've made sure it doesn't get in the way of your actual work while it does its thing.

You can find all the details on setting it up in the Agent Installation and Configuration section.

Data Flow ​

So, how does the data actually travel? It's a pretty straightforward process, really.

  1. First, the Txlog agent keeps a close watch on DNF activities on your workstations. It catches every transaction the moment it happens.
  2. We then take that transaction metadata and break it down into a structured format—package names, versions, timestamps, you name it.
  3. Next, the agent encrypts that data and sends it over the network using secure protocols. We wouldn't want that info floating around in the clear, would we?
  4. Finally, the server takes that incoming data, validates it, and tucks it away safely in the PostgreSQL database for whenever you need to audit it.
