Logs are an essential part of observing any service; without them you are flying blind. But collecting and analyzing them can be a real challenge -- especially at scale. Not only do you need to solve the basic task of collecting your logs, but you must do it in a reliable, performant, and robust manner. Nothing is more frustrating than having your logs pipeline fall on it's face during an outage, or even worse, disrupt more important services!
Fear not! In this guide we'll show you how to send send logs to AWS S3 and build a logs pipeline that will be the backbone of your observability strategy.
What is AWS S3?
Amazon Simple Storage Service (Amazon S3) is a scalable, high-speed, web-based cloud storage service designed for online backup and archiving of data and applications on Amazon Web Services. It is very commonly used to store log data.
How This Guide Works
We'll be using Vector to accomplish this task. Vector is a popular open-source utility for building observability pipelines. It's written in Rust, making it lightweight, ultra-fast and highly reliable. And we'll be deploying Vector as a daemon.
The daemon deployment strategy is designed for data
collection on a single host. Vector runs in the background, in its own process,
collecting all data for that host.
Typically data is collected from a process manager, such as Journald via
journald source, but can be collected
through any of Vector's sources.
The following diagram demonstrates how it works.
What We'll Accomplish
To be clear, here's everything we'll accomplish in this short guide:
Install Vectorcurl --proto '=https' --tlsv1.2 -sSf https://sh.vector.dev | shexplain this command
Or choose your preferred method.
Configure Vectorcat <<-VECTORCFG > vector.toml[sources.in]include = ["/var/log/nginx/*.log"] # requiredtype = "file" # required[sinks.out]bucket = "my-bucket" # requiredinputs = ["in"] # requiredregion = "us-east-1" # required, required when endpoint = ""type = "aws_s3" # requiredVECTORCFGexplain this command
Start Vectorvector --config vector.toml
That's it! Simple and to the point. Hit
Vector is powerful utility and we're just scratching the surface in this guide. Here are a few pages we recommend that demonstrate the power and flexibility of Vector:
