Building Syslog Server from Scratch

Hello,

I have 5 days off and I will staying home for thanksgiving. I have plenty of time and I wanted to learn few things and build something.

I wanted to write a syslog collector that has APIs and database. I wanted to know what latest trends that I can use to build something cool. One other advantage is that, it can be really helpful for my work as well.

I did some google search,

- Elasticsearch - Logstash - Time series data.

What stack should I use. I'm willing to learn anything.

Thank you and happy thanksgiving :)
