Log Parser
A playground that generates one log parsing activity at a time, and regenerates a new one when you complete each activity. It uses authentic log formats such as nginx access logs and syslog entries to simulate real parsing needs. The operator avoids repeats until it has exhausted the full activity list, then starts a new randomized cycle. Github: https://github.com/lpmi-13/logparser-lab-operator
