How to configure logging to a file before parsing

When you're setting up PBX Data Logger, a clean, unaltered log file is often your best safety net. You need a log file when you're diagnosing connection issues, verifying what the PBX is actually sending, or preparing to parse data later with scripts or third-party tools. It's the authoritative record of raw input, letting you confirm formats, timestamps, and full message content before any processing happens.

In emergencies-like unexpected call drops, billing disputes, or security incidents-raw logs help you reconstruct events fast. You can trace call flows, correlate messages across systems, and provide evidence that stands up to audits. Because the data is complete and time-aligned, you can identify the moment something went wrong and the surrounding conditions. The logger can also restore some records in a database from log files if you accidentally deleted it.

You want log files without any modifications to avoid losing context or introducing mistakes. Filters, formatting, or transformations can hide fields, change order, or alter values-making troubleshooting harder and evidence less reliable. Capturing the original stream preserves integrity, ensures reproducibility, and keeps your options open for any downstream analysis or tooling.

1. Open the configuration settings in the "Main menu → Options → Manage configuration → Your configuration → Edit" menu.

2. Go to the "Log files → Log rotation" tab.

3. Configure the log file settings as shown below. The program will create a new log file every day. Of course, you can select another folder for log files.
