Send logs to GCP Cloud Storage

A simple guide to send logs to GCP Cloud Storage in just a few minutes.

Logs are an essential part of observing any service; without them you'll have significant blind spots. 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, cause the outage!

Fear not! In this guide we'll build an observability pipeline that will send logs to GCP Cloud Storage.

Background

What is GCP Cloud Storage (GCS)?

Google Cloud Storage is a RESTful online file storage web service for storing and accessing data on Google Cloud Platform infrastructure. The service combines the performance and scalability of Google's cloud with advanced security and sharing capabilities. This makes it a prime candidate for log data.

Strategy

How This Guide Works

We'll be using Vector to accomplish this task. Vector is a popular open-source observability data platform. It's written in Rust, making it lightweight, ultra-fast and highly reliable. And we'll be deploying Vector as a agent.

Vector daemon deployment strategyVector daemon deployment strategy
1. Your service logs to STDOUT
STDOUT follows the 12 factor principles.
2. STDOUT is captured
STDOUT is captured by your platform.
3. Vector collects & fans-out data
Vector will sends logs to [GCP Cloud Storage](https://cloud.google.com/storage).

What We'll Accomplish

We'll build an observability data platform that:

  • Collect your logs from one or more sources
  • Sends logs to GCP Cloud Storage.
    • Buffers data in-memory or on-disk for performance and durability.
    • Compresses data to optimize bandwidth.
    • Automatically retries failed requests, with backoff.
    • Securely transmits data via Transport Layer Security (TLS).
    • Batches data to maximize throughput.

All in just a few minutes!

Tutorial

  1. Install Vector

    curl --proto '=https' --tlsv1.2 -sSf https://sh.vector.dev | sh
  2. Configure Vector

    cat <<-'VECTORCFG' > ./vector.toml
    [sinks.out]
    type = "gcp_cloud_storage"
    inputs = [ "my-source-or-transform-id" ]
    bucket = "my-bucket"
    [sinks.out.encoding]
    codec = "ndjson"
    VECTORCFG
  3. Start Vector

    vector --config ./vector.toml
  4. Observe Vector

    vector top
