Below is the list of blog posts with the “Fault tolerance” tag.

Imagine trying to buy tickets for your favorite band’s concert, only to find the website down just minutes before they sell out. Or logging into the cloud to look through your cherished digital photos and discovering they’ve been lost because of a data center failure. These scenarios are — at best — frustrating for you.

When considering your log collection strategy, a decision you have to make is which transport protocol to use to transfer logs from source to destination. The choice is often between the two most commonly used protocols, UDP (User Datagram Protocol) and TCP (Transfer Control Protocol). Which one to use depends on the type of logs you need to transfer, and whether performance or reliability is more important. This blog post will compare these protocols, discuss why TCP is usually the preferred choice, and provide some options to further increase log delivery reliability with NXLog.
