World of Observability and Resiliency

This month at Planet Mainframe we’re delving into the world of observability and resiliency. Far from being buzzwords, the complex nature of modern IT environments makes this a theme worth a lot of spilled ink. 

Our trivia quiz this week will focus on observability. This is a big topic since, by definition, it touches on almost every aspect of a functioning IT environment—from complexity management and resource optimization to security monitoring and compliance and governance.

Observability is like being gifted with an all-seeing eye that allows you to peer into the labyrinth of interconnected systems, identifying the tiniest hiccup or bottleneck before it escalates into a full-blown crisis.

If you’re new to the topic of observability or feel the need of a refresher, you might want to wander over to a recent Planet Mainframe article: ”The importance of Observability in Modern IT Environment” and give it a quick read. Then come back and take our quiz!

1. What is observability in today’s IT terms?

 The ability to hide system operations

 The capability to understand and analyze system behavior based on external outputs

 The process of directly modifying system components

 The practice of randomly monitoring system performance

2. What are some core components of observability in IT systems?

 Counters and loops

 Variables and functions

 Monitoring, Logging, Tracing

 Arrays and strings

3. Which component of observability serves as a system diary, documenting discrete events?

 Metrics

 Traces

 Logs

 Observations

4. How does observability contribute to system stability?

 By introducing more complexity

 By identifying unstable areas for optimization

 By slowing down system operations

 By ignoring system performance

5. What is one challenge associated with implementing observability?

 Lack of skilled personnel

 Overabundance of available data

 Minimal system complexity

 Static IT environments

6. What is the role of observability in IT resilience?

 To increase system complexity

 To make problems intensify

 To identify and mitigate issues proactively

 To decrease user experience

7. Which of these is an emerging trend in observability?

 Avoiding the use of AI and machine learning

 Real-time data representation

 Fragmented monitoring solutions

 Isolated observability

8. Which of the following is NOT a best practice for maintaining observability?

 Continuous monitoring

 Isolating observability from the DevOps culture

 Integrating observability and DevOps

 Using open-source tools

9.  What is the purpose of continuous monitoring in observability?

 To ensure visibility and detect anomalies in real-time

 To ignore system performance

 To avoid collaboration with others

 To rely solely on historical data

10.  Why is observability essential in today’s IT environment?

 To increase system complexity

 To deliver an outstanding user experience

 To slow down system operations

 To decrease system availability
