Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available.

Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most.

This book is excellent. It is the most comprehensive, practical guide on using Prometheus available. What differentiates this book from other similar materials is the emphasis on real world usage. Exploring supplementary tools like Pint and Sloth bring your Prometheus use to the next level. I've referenced this book multiple times already while working and have linked chapters to my peers. It is well written and worth a buy!

This book is a perfect guide for those who want to take their Prometheus monitoring skills to the next level. It dives deep into operating, scaling, and extending Prometheus for various workloads, from small on-premise deployments to globally distributed cloud environments.To understand Prometheus in a better way, William has divided this book into three parts:1. Fundamentals of Prometheus - This part lays the groundwork by explaining observability and how Prometheus fits in. It then covers deployment, data model, query language (PromQL), service discovery, and alerting.2. Scaling Prometheus - Moving beyond basic setups, this part dives into horizontal scaling with sharding and federation. You'll also learn techniques for debugging performance issues and optimizing data ingestion.3. Extending Prometheus - This section explores integrating Prometheus with other tools and technologies. It covers remote storage options like VictoriaMetrics and Mimir, achieving high availability with Thanos, and utilizing OpenTelemetry for broader observability.If you're already comfortable with Prometheus basics and want to push your expertise further, this book offers advanced topics to take your monitoring capabilities to the next level.I was intrigued by few advanced concepts that were -1. Scaling Prometheus2. Optimizing and Debugging Prometheus3. Utilizing Remote Storage Systems with Prometheus4. Extending Prometheus Globally with Thanos5. Utilizing Continuous Integration (CI) Pipelines with Prometheus6. Integrating Prometheus with OpenTelemetryAs a DevOps Engineer, I can say that you will find this book valuable if you want to take your Prometheus skills to the next level and build robust monitoring solutions for demanding environments.

I purchased this eBook 2 days ago; it's over 300 printed pages of content. I spent about 2 hours with it over the weekend, but still have 93% of the content to read. That is, I have no idea what kind of rating to give to this material, but I'm already being prompted to review it. This book might be amazing! Or it might be awful! I don't know (yet)! My options are to review it now and (hopefully) stop the emails, or try to figure out how to unsubscribe (which I shouldn't have to do, and which isn't guaranteed to work), or I have to build a spam filter to block messages from feefo (which I shouldn't have to do, and maybe don't want to do, because maybe I want to come back and leave a legit review at some point). So I'm leaving this crappy 3-star review right now in hopes that the emails will stop and that maybe somebody somewhere will catch a clue: Wait a week, maybe 2 ~ 4 weeks, before pushing for feedback on a large volume like this.

Half of the book is things NOT Prometheus, all chosen examples are written in Go (not a big deal per se, python might have been more common..no stars reduced due to this though, just observation). Chose container tech is linode (exactly, why?!). For local setups, local testing, trying docker would have made much more sense. Linode market share is 2.6%, definitely not amongst most popular ones.I would have spent more time on PromQL , data collection, exporters, push proxies, how to handle, mitigate offline collection difficulties (yes, surprisingly network connection is not always available), or having mobile clients which are not continuously available, what measurement to take,ensure if big lump of metrics arrive late, instead of connecting to huge lump of exporters (hard coded), how to ensure exporters are available in widely dynamic networks. Lot of practical solutions stemming from real life monitoring dilemmas, just happy-path is considered.So half of book is not Prometheus, grand ignorance of real world issues, 2 stars off.Rest, it's pretty good, does go to depths of Prometheus, focuses on having it running and keeping it running, data compacting, scaling (alongside Kubernetes), templates, alerting, SLAs,SLOs.Worth the money still? Really depends on your needs, might be. I don't have another book to compare, I'm very familiar with large scale monitoring solutions with decades of experience, Prometheus itself was somewhat new to me. I consider the Prometheus part of the book worth compared to available online documentation.But I really was anticipating MASTERING prometheus, did fall short for afore mentioned reasons.
