Hello,

LFS241 - Monitoring Systems and Services with Prometheus is now live!

Prometheus is an open source monitoring system and time series database that is especially well-suited for monitoring dynamic cloud environments. It contains a powerful query language and data model, in addition to integrated alerting and service discovery support. LFS241 exposes new Prometheus users to many of its major features, best practices and use cases. Upon completion, learners will be able to monitor their systems and services effectively with Prometheus.

One great way to interact with your peers taking this course is using the Class Forum:

• Discuss concepts, tools, and technologies presented in this course, or related to the topics discussed in the course material.
• Ask questions about the course content.
• Share resources and ideas related to Prometheus.

When starting a thread, be as specific as you can, both in the title and the body of the thread, identifying the chapter and page you are referring to.

We hope you have a great learning experience!

Lab 5.4 function
_ predict_linear(demo_disk_usage_bytes{job="demo"}[15m])_ not correct, func needs 2 arguments and must be like
predict_linear(demo_disk_usage_bytes{job="demo"}[15m], 3600)

Lab 6.3
histogram_quantile(0.9, sum without(instance, status)
(rate(demo_api_request_duration_seconds_bucket{job="demo"}[5m]))
miss ')' at the end. It must be
histogram_quantile(0.9, sum without(instance, status)
(rate(demo_api_request_duration_seconds_bucket{job="demo"}[5m])))

Lab 9.1
for exersise we need not master banch and rigth command for git clone is

Lab 10.1 func

sum without(cpu) rate(node_cpu_seconds_total{job="node"}[1m]) dont work and rate must be in (), like
