I've just finished the Observability Course and I'll start to prepare the certification.
Reviewing the exam objectives there is one it is not clear to me
- Configure and run Metricbeat to collect metrics from an operating system
- Configure and run Metricbeat to collect metrics from a running service
- Enable and configure a Metricbeat module to collect the metrics of a specific service
- Use the Metrics app in Kibana to analyze and answer questions about metrics collected in Elasticsearch
1,3 and 4 completely clear, but in 2 I'm not sure what we need to achieve.
Maybe it refers to the service dataset in the system module?
Probably I'm missing something...
Thanks a lot
