New Book Releases: Prometheus 3 and LLMOps for DevOps Engineers

Two new titles are out under the Bitline Press imprint, both aimed at engineers who want practical, example-driven guides rather than theory. One covers monitoring with Prometheus 3, the other covers running large language models in production the way you would run any other service. Here is what each one is and who it is for.

Prometheus 3 for Beginners

Prometheus is the monitoring and alerting system most teams reach for first, and version 3 is the current generation. This book is a hands-on start for anyone new to it. It does not assume you have used Prometheus before, and it works through real examples rather than dumping reference material on you.

What it covers:

• Installing Prometheus 3 and understanding the metrics data model
• Writing PromQL queries, from simple lookups to rate and aggregation
• Setting up exporters to collect metrics from your systems and applications
• Writing alerting rules and wiring up Alertmanager
• Building dashboards and reading them under real conditions

It is a good fit if you are a sysadmin, developer, or new SRE who keeps hearing “just check Prometheus” and wants to actually understand what that means.

LLMOps for DevOps Engineers

Running large language models in production is a DevOps problem as much as a machine learning one. This book takes the practices you already know, deployment, monitoring, cost control, versioning, and applies them to LLM-backed systems. It is written for engineers who are comfortable with DevOps and want to extend that skill set rather than start from zero.

What it covers:

• Deploying and serving LLMs, and the infrastructure choices that come with it
• Observability for LLM systems: what to measure when the output is text, not a status code
• Evaluating model quality and catching regressions before users do
• Controlling cost, latency, and token usage in production
• Managing prompts, versions, and safe rollout of model changes

It suits practicing DevOps engineers and SREs who are being asked to put an LLM feature into production and want to do it reliably.

Which one is for you

If you are new to monitoring and want a grounded, practical start, begin with Prometheus 3 for Beginners. If you already run infrastructure and are moving into LLM-backed services, LLMOps for DevOps Engineers picks up where your existing skills leave off. The two also pair well: solid monitoring habits from the first book carry directly into the observability chapters of the second.

Both are available on Amazon in paperback and Kindle. For more recommended titles, see the full DevOps and SRE books list.
