Things have been very hectic, so much so we’ve not really had much time to write a blog. Most of which has been related to my Fluentd book, so what has been happening (and keep an eye on my Twitter account for a promo code 🙂 ) …

  • Several virtual conferences (Open Source Summit, SPOUG and Oracle APAC Groundbreakers to name just a few)
  • Perhaps the biggest bit has been the book:
    • First 4 chapters went through a rigorous peer review, as a result a number of improvements have been made,
    • with Chapter 5 having been reviewed by our technical editor, and little bit of refinement applied it should be reaching MEAP very very soon along with updated appendices,
    • Chapter 6 has been reviewed by our development editor, so some revisions to apply and then onto the technical editor,
    • Chapter 7 writing in progress, with about 1/3rd complete including examples of applying scaling configuration that can be run on a desktop

So what is to follow:

  • We’re on Manning’s Twitch channel to do a session, which will cover Fluentd, some examples, the book and what it will cover,
  • Once Chapter 7 is done, then we go through a comprehensive review with external input. Depending on the feedback from this, we make another sweep through the existing chapters to make further improvements,
  • Chapter 8 I suspect will be the hardest to write, as we actually get into creating our own Plugin. So I it maybe a little while before this gets completed. The subsequent chapters will come more easily as we’ve got them part written in a rough draft already,
  • We have another round of external peer reviewing to come which will cover everything, so I’m sure we’ll be doing some refinements
  • A podcast recording is scheduled in December.

Talking of Manning on Twitch, this looks like a bit of a hidden Gem – worth looking at not only because of the live stream, but all the previous recordings with other Manning authors are available to watch.

If that isn’t enough with a day job, we have had some major work done on our house. Now we’re moved back in, there are lots of DIY jobs to do, get all the furniture back from storage. Every room apart from the kitchen needs to be painted. But that is my sob story.

I’m hoping to find time to experiment with Oracle’s new cloud native Log Management as this is built on Fluentd foundations and a little bit with API tech – but this is likely to be the Christmas break.

Unified Logging with Fluentd – Sample and more

Manning have made section of my book freely available. The excerpt from the first draft of my book Unified Logging with Fluentd illustrates the Fluentd take on Hello World – the extract can be found at http://mng.bz/nzm8. This is from the 1st chapter to help set the scene of how Fluentd can be configured. The following quote comes from one of the peer reviewers:

The extract includes the use of the log simulator tool – https://github.com/mp3monster/LogGenerator which takes some configuration and can either play synthetic data or replay real logs as current log events in what ever format you want to simulate – for example standard Log4J through to Apache Server logs with the relevant time separation between events.

Book Discount …

If this isnt enough temptations, then perhaps saying that on September 22: Deal of the Day book is my book Unified Logging with Fluentd. Use code dotd092220au at https://bit.ly/3mBRLK2

Book Project Unveiled – Unified Logging with Fluentd

Fluentd is both an open source solution for making log management so much easier to work with, particularly for distributed / multi component solutions. But not only that it is supported by many log analytics tools, and central to several cloud vendors log management services.

The goal of the book is to explain how Fluentd can help us and to use the tool. We can’t cover every possible plugin, so we walk through the use of enough plugins and the way features interact you can extrapolate to other plugins.

We’ve been told because of current events in the US that this event is going to be rescheduled.

I am pleased to say that I will be talking about Fluentd at the Cloud Native eParty virtual conference on 2nd June 2020. I’ll be presenting at 4pm, and then hanging out on the conference slack channel to answer any more questions people might have.

Hope to see you online.

Mastering FluentD configuration syntax

Getting to grips with FluentD configuration which describes how to handle logging event(s) it has to process can be a little odd (at least in my opinion) until you appreciate a couple of foundation points, at which point things start to click, and then you’ll find it pretty easy to understand.

It would be hugely helpful if the online documentation provided some of the points I’ll highlight upfront rather than throwing you into a simple example, which tells you about the configuration but doesn’t elaborate as deeply as may be worthwhile. Of course, that viewpoint may be born from the fact I have reviewed so many books I’ve come to expect things a certain way.

But before I highlight what I think are the key points of understanding, let me make the case getting to grips with FluentD.

Why master FluentD?

FluentD’s purpose is to allow you to take log events from many resources and filter, transform and route logging events to the necessary endpoints. Whilst is forms part of a standard Kubernetes deployment (such as that provided by Oracle and Azure for example) it can also support monolithic environments just as easily with connections working with common log formats and frameworks. You could view it as effectively a lightweight (particularly if you use FluentBit variant which is effectively a pared-back implementation) middleware for logging.

If this isn’t sufficient to convince you, if Google searches are a reflection of adoption, then my previous post reflecting upon Observability -London Oracle Developer Meetup shows a plot reflecting the steady growth.  This is before taking into account that a number of cloud vendors have wrapped Fluentd/fluentbit into their wider capabilities such as Google (see here).

Not only can you see it as middleware for logging it can also have custom processes and adapters built through the use of Ruby Gems, making it very extensible.

Remember these points

and mastering the config should be a lot easier…

Observability -London Oracle Developer Meetup

meetup-monitoringLast night was the London Oracle Developer Meetup’s sessions around observability.  Andrei Cioaca with a focus on the use of OpenTracing as provided by Jaeger, in a standard Kubernetes deployment with Istio – realized with Oracle Kubernetes Engine (OKE).  This was followed by my session on another pillar using logging via FluentD. Also incorporated into standard Kubernetes, but also able to support traditional monolithic use cases.

Andrei provided a great overview of the 3 pillars and the strengths and weaknesses of the different pillars. With the basics covered Andrei then dove into the configuration and execution of Istio combined with Jaeger and the corresponding insights available.  including a look at the kinds of visual insights that Jaeger and Kiali provide.  Some probing conversations followed about the relationship to Spring Cloud Sleuth, Open Zipkin and the OpenTracing as a concept more generally.

Andrei’s presentation material can be found in his GitHub repository here.

Google Analytics on Search Terms

My session followed a pizza break, as there was a delay in its arrival. With everybody having chatted over pizza about OpenTracing, we picked up on FluentD and the Logging aspect to Observability. FluentD, as an open-source project has been growing steadily, and actually baked into several Log Analytics products and services – as the above analytics from Google shows.

The presentation looked at the growing challenges of modern software in terms of making sense of logging.  We explored the capabilities of FluentD before drilling into real-world use cases and potential deployment models.

As you’ll see from the slides we ran a couple of demos. The configuration for the demos can be found at https://github.com/mp3monster/fluentd-demos along with an example payload.

The next meetup we have organized is around Blockchain, all the details can be found at https://www.meetup.com/Oracle-Developer-Meetup-London/events/264661742/.
