# Conclusion
|
|
|
|
A robust monitoring and alerting system is necessary for maintaining and
|
|
troubleshooting a system. A dashboard with key metrics can give you an
|
|
overview of service performance, all in one place. Well-defined alerts
|
|
(with realistic thresholds and notifications) further enable you to
|
|
quickly identify any anomalies in the service infrastructure and in
|
|
resource saturation. By taking necessary actions, you can avoid any
|
|
service degradations and decrease MTTD for service breakdowns.
|
|
|
|
In addition to in-house monitoring, monitoring real-user experience can
|
|
help you to understand service performance as perceived by the users.
|
|
Many modules are involved in serving the user, and most of them are out
|
|
of your control. Therefore, you need to have real-user monitoring in
|
|
place.
|
|
|
|
Metrics give very abstract details on service performance. To get a
|
|
better understanding of the system and for faster recovery during
|
|
incidents, you might want to implement the other two pillars of
|
|
observability: logs and tracing. Logs and trace data can help you
|
|
understand what led to service failure or degradation.
