Prometheus Monitoring and Alerting

Collect time-series metrics from applications and infrastructure using Prometheus exporters, scraping, PromQL, recording and alert rules, and Alertmanager routing.

How this module works

From concept to production evidence

Expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

Learning outcomes

Explain Prometheus data and pull architecture
Use exporters and scrape configuration
Write PromQL
Create alert rules
Route and group alerts with Alertmanager
Monitor Kubernetes

Prometheus architecture

Prometheus architecture turns service behavior into evidence that supports detection, diagnosis, capacity decisions, and measurable reliability within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

Metrics

Metrics turns service behavior into evidence that supports detection, diagnosis, capacity decisions, and measurable reliability within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

Exporters

Exporters governs how a request is named, addressed, routed, filtered, transported, protected, and delivered to a healthy endpoint within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

Scraping

Scraping turns a manual or repeated decision into versioned, parameterized, testable, and observable execution within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

PromQL

PromQL turns service behavior into evidence that supports detection, diagnosis, capacity decisions, and measurable reliability within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

Alert rules

Alert rules turns service behavior into evidence that supports detection, diagnosis, capacity decisions, and measurable reliability within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.

Alertmanager

Alertmanager turns service behavior into evidence that supports detection, diagnosis, capacity decisions, and measurable reliability within Prometheus Monitoring and Alerting. It is not an isolated definition: its value appears when it supports expose bounded-cardinality metrics, discover targets, scrape at a purposeful interval, write queries around service behavior, alert on sustained user impact, and route notifications with inhibition and ownership.
