Prometheus
Following adds this technology to your private workspace so related learning is easier to organise and revisit.
What is Prometheus?
Prometheus is an open-source monitoring system and time-series database designed around labelled metrics and a pull-based collection model. This profile connects the concept to KBY's practical engineering guidance.
It scrapes targets, evaluates PromQL queries and recording or alerting rules, and stores samples locally. Service discovery and federation support dynamic environments, while cardinality, retention and high availability require explicit design.
Collect, query and alert on numerical service and infrastructure telemetry.
- Kubernetes cluster monitoring
- Time-series metrics collection
- Alerting via Alertmanager
