Getting Started Monitoring with Prometheus and Grafana
The document is a presentation that introduces Prometheus and Grafana as tools for monitoring systems and applications. It covers the importance of monitoring, what to monitor, and key concepts in site reliability engineering, along with an overview of Prometheus and Grafana features and capabilities. A short demo is included to illustrate the tools in action, along with references for further information.

- 13. 13 The Four GoldenSignals Site Reliability Engineering
- 14. 14 Latency The time ittakes to service a request. Important to distinguish between the latency of successful and failed requests.
- 15. 15 Traffic A measure ofhow much demand is being placed on your system, measured in a high- level system-specific metric.
- 16. 16 Error The rate ofrequests that fail, either explicitly (e.g. HTTP 500s), implicitly (HTTP 200 success with wrong content)
- 17. 17 Saturation How “full” yourservice is. A measure of your system fraction, emphasizing the resources that are most constrained (e.g. in a memory- constrained system, show memory)
- 18. Prometheus – AnIntroduction
- 19. 19 Prometheus Prometheus is anopen-source systems monitoring and alerting toolkit originally built at SoundCloud. It is now a standalone open source project and maintained independently of any company. https://prometheus.io
- 20. 20 Components ● Prometheus server whichscrapes and stores time series data ● Client libraries for instrumenting application code ● A push gateway for supporting short-lived jobs ● Special-purpose exporters (for HAProxy, StatsD, Graphite, etc.) ● An alertmanager ● Various support tools
