Introduction

Welcome to the documentation for Varlog, a powerful log aggregation tool designed to make managing logs from remote servers easier and more efficient. Varlog is more than just a log aggregator, it's a complete log management solution that helps you stay on top of your logs and troubleshoot issues quickly and efficiently.

One of Varlog's standout features is its efficient log-reading algorithm, which is designed to read logs of any size quickly and efficiently. This algorithm uses a tail-based reversed iterator chunking approach, which allows Varlog to read the most recent output of any size log file in milliseconds.

But Varlog is more than just a log reader. It also comes with strong security features built-in. By default, access to logs and servers is restricted, and users must explicitly request access to them. Varlog supports JSON Web Tokens (JWT) as its authentication method, ensuring that users are securely authenticated before accessing logs.

Varlog also features a powerful API Sidecar, which is easy to install and run as a daemon on any hardware. The sidecar is platform-agnostic thanks to Rust's cross-compilation functionality, which means that it can be used in almost any environment. This orthogonal reuse feature doesn't impact the state of your application, regardless of Varlogs, making it easy to integrate Varlog into your existing infrastructure.

For users with larger networks, Varlog can also be used as a mesh network. This means that any server can be queried and, given it's provided with the correct access, that primary server will dispatch a retrieve request to all servers and aggregate. the logs. This makes it easy to access logs from any server on your network, without the need for additional configuration or setup.

One of the key features of Varlog is its flexibility. We understand that every organization has unique logging requirements, which is why Varlog can be easily configured to fit your specific needs. Whether you need to store logs for compliance purposes, integrate with other tools in your tech stack, or customize the log aggregation process itself, Varlog has you covered.

With Varlog, you can easily access your logs and troubleshoot issues with minimal delay, ensuring that your systems stay up and running smoothly. Whether you're a small business owner or a large enterprise, Varlog can help you streamline your log management process, making it easier to access and analyze your logs. With its efficient log-reading algorithm, strong security features, and powerful API Sidecar, Varlog is the go-to log management solution for any business.

We're proud of the work we've done to build Varlog, and we're excited to share it with you. Whether you're a user looking to simplify your logging workflow or a contributor interested in helping us improve Varlog even further, we hope this documentation will provide you with the information you need to get started.
