4. Monitoring

5. 5
Why Monitor?

6. 6
Know when things go wrong

7. 7
Alerting

8. 8
Be able to debug and gain insight

9. 9
What to Monitor?

10. 10
Hosts
CPU, Memory, I/O, Network,
Filesystem

11. 11
Containers
CPU, Memory, I/O, Restarts,
Throttling

12. 12
Applications
Throughput, Latency

13. 13
The Four Golden Signals
Site Reliability Engineering

14. 14
Latency
The time it takes to service a request. Important
to distinguish between the latency of successful
and failed requests.

15. 15
Traffic
A measure of how much demand is being
placed on your system, measured in a high-
level system-specific metric.

16. 16
Error
The rate of requests that fail, either explicitly
(e.g. HTTP 500s), implicitly (HTTP 200 success
with wrong content)

17. 17
Saturation
How “full” your service 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 – An Introduction

19. 19
Prometheus
Prometheus is an open-source systems monitoring
and alerting toolkit originally built at SoundCloud. It
is now a standalone open source project and
maintained independently of any company.

Components
●
Prometheus server which scrapes 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

23. Grafana – An Introduction

24. 24
Grafana
The analytics platform for all your metrics
Grafana allows you to query, visualize, alert on and
understand your metrics no matter where they are
stored. Create, explore, and share dashboards with
your team and foster a data driven culture.
Trusted and loved by the community.
