I needed to investigate the log files of an aws loadbalancer. In particular i wanted to have the top 50 IP addresses. Ulitmatly i want to have something similar to what https://vegalog.net/ provides, only that its running locally, and written in rust.
I'm fairly new to Rust so happy to receive any Feedback you might have on how to improve the code.
Download the logfiles you want to analyze into a local folder and unzip
them. They are stored as gzip's. Then set LOGDIR env var to point to that folder.
Signup for an IPINFO Token on https://ipinfo.io/ and provide that token
via the IPINFO_TOKEN env var.
On starting lb-analyzer will read all logs files in that directory and
count the occurences of ip addresses. It will produce a simple csv output
file that holds all these addresses with their occurence count. The
first 100 addresses will be looked up via the ipinfo.io service.
