SLF4J VS Monolog

A few years ago, my team moved from Java to Go. Working on Go projects, we encountered a wide variety of logging frameworks with different APIs, configuration, and formatting. We soon found ourselves longing for a logging abstraction layer like Java’s slf4j, which had proven invaluable for use in reusable libraries or configuring and debugging production systems. So, not long after moving to Go, we began working toward replacing what we had lost in slf4j.

I'm not familiar with Serilog as I code mostly in Java, use slf4j (logs to stdout) and our apps send logs to Cloudwatch using the task definition's awslogs configuration. I prefer it this way because I can customize the log configurations in my task definitions. Also the default stream name has this format prefix-name/container-name/ecs-task-id so I can easily identify the logs of the task I want to look at. I haven't experienced any downsides with this approach and our apps publish a shit ton of logs. Cloudwatch approach looks like you can customize the stream name?

slf4j is open source. You can look at the code.

> My God. Logging in protobuf?

Yes, or any other data format and/or transport protocol.

I'm surprised this is up for debate.

> Logging is the lowest of all debugging utilities - its the first thing you ever do writing software - “hello world”. And, while I admire structural logging, the truth is printing strings remains (truly) the lowest common denominator across software developers.

This sort of comment is terribly miopic. You can have a logging API, and then configure your logging to transport the events anywhere, any way. This is a terribly basic feature and requirement, and one that comes out of the box with some systems. Check how SLF4J[1] is pervasive in Java, and how any SLF4J implementation offers logging to stdout or a local file as a very specific and basic usecase.

It turns out that nowadays most developers write software that runs on many computers that aren't stashed over or under their desks, and thus they need efficient and convenient ways to check what's happening either in a node or in all deployments.

To add onto this, what's more commonly done these days is to use a library like Monolog which can be configured with multiple log handlers. One of the handlers which are typically enabled is one which writes to error_log. You can add more which write directly to a logging service like Sentry or whatever, or even in dev write an HTTP header paired with a browser extension which puts your backend log messages in your browser console (see the handler + install the extension for chrome or firefox)

Monolog is a highly regarded PHP logging library with open source code. This project extends a straightforward and adaptable API, allowing developers to log messages from their PHP applications to diverse channels, including files, databases, and various third-party services. The modularity of this project’s source code provides an assortment of handlers and processors that seamlessly combine and configure to cater to specific logging requirements for any application.

If you need something more flexible you could always use Monolog which provides a bunch of adapters to log to any service want. You could for example use the syslog adapter to send your logs to syslog, and then configure rsyslog to print them directly into your terminal (or just `tail -f` a log file).

So far, I've been discussing what PHP itself has to offer, which, quite frankly, is not very appealing. Luckily, though, there are great developers involved in pushing beyond those boundaries, making the appearance of great tools a reality. That is the case for Monolog.

Laravel (and many other frameworks) use the Monolog Package for logging by default. Using their formatter does everything you need!

Nowadays all popular frameworks comes with logging system built in. If not, you should use http://seldaek.github.io/monolog/.

Laravel logging is created on top of Monolog, which is a powerful logging library for PHP projects. In this guide, we will be looking at how to send our laravel logs to telegram channel with the help of the Telegram Bot API.
