Observability vs Monitoring: What are the Differences

Observability	Monitoring
A measure of how well the internal states of a system can be inferred from the knowledge of its external outputs	The process of collecting, processing, and displaying real-time information about a system’s performance.
Understanding the 'why' of a system behavior, typically to diagnose unexpected issues or behaviors.	Focused on the 'what'— what is happening in the system based on predefined thresholds and checks.
Uses metrics, logs, and traces to provide a holistic view of system performance.	Mainly utilizes metrics and alerts based on predefined parameters.
More proactive, focuses on understanding the system to prevent issues before they arise.	More reactive, usually acts upon issues after they have occurred.
Ideal for complex, distributed, and dynamic systems where the behaviors are not always predictable.	Works well for static or less complex systems where behaviors can be predicted accurately.
To provide a comprehensive understanding of system performance in different scenarios.	To keep the system performance within acceptable limits and detect when it goes out of those limits.

How to Implement DevOps Observability

Implementing DevOps Observability is not a one-size-fits-all process, as it will depend on your specific system and business needs. However, there are certain key steps that can guide you toward an effective and efficient observability strategy.

1. Define Your Key Performance Indicators (KPIs)

Before you can observe anything, you need to know what you're looking for. Identify the key performance indicators for your system. These could be things like response times, error rates, throughput, or CPU usage. Having clear KPIs helps you understand what normal performance looks like, making it easier to spot anomalies or issues.

2. Leverage the Three Pillars of Observability

Observability relies heavily on metrics, logs, and traces - often referred to as the three pillars of observability. Make sure your system can produce these three types of data.

Metrics:

Implement a metrics collection system that can track important performance metrics over time. Tools like Prometheus, Datadog, or New Relic can be useful for this.

Logs:

Ensure that your applications and infrastructure are set up to log important events. Consider using a centralized logging solution like ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk for easier log management.

Traces:

For distributed systems, distributed tracing tools like Jaeger or Zipkin can help visualize the path of requests through your services.

3. Instrument Your Code

To gather detailed information about how your software is behaving, you'll need to instrument your code. This involves adding code to your application to collect performance data, log important events, and trace requests.
