The Difference Between Mobile Observability and Mobile Monitoring

The Difference Between Mobile Observability and Mobile Monitoring

Application performance monitoring is a mobile team’s bread and butter when it comes to debugging and diagnosing system issues. If you’re a mobile developer, you’re likely familiar with monitoring platforms that help you track problems and identify failures that impact your app’s user experience.

As essential as monitoring is, mobile development teams need deeper insights into their apps when they crash or malfunction. The mobile app industry is rapidly shifting toward distributed and serverless architecture, which entails more complicated software. This means legacy monitoring techniques are becoming less reliable for today’s complex applications.

What your app needs now is mobile observability. But what’s the real difference between mobile observability and monitoring? Let’s explore this critical distinction and why, ultimately, you don’t have to choose between them.

‍

What is Mobile App Monitoring?

‍

Mobile application performance monitoring is the process of ensuring an app’s system operates as it should, including factors like speed and scope. Monitoring tools track apps in the background, so developers don’t have to keep a constant eye on their systems manually. These tools collect and analyze data that tracks your app’s ability to achieve its objectives based on metrics you’ve predefined.

Because you determine the metrics monitoring tools should look out for, they only detect known failure modes. Mobile app monitoring works best when the issue is predictable, which includes many system failure types, but doesn’t always give you the necessary context to develop solutions quickly.

Some of monitoring’s basic functions include:

  • Overseeing server CPUs and resource usage
  • Tracking network traffic patterns
  • Identifying trends in error rates
  • Alerting you about slow-loading pages
  • Analyzing logs to determine request timing

A ride-sharing app, for example, might use monitoring to track how quickly their servers respond to ride requests during peak hours. If response times exceed a predefined threshold, the monitoring system alerts the development team to investigate.

However, monitoring is useful for tracking long-term trends in your code. If you notice a problem that is consistent in frequency and impact, instead of only affecting a select few users occasionally, that indicates where the problem is and what you can do about it.

‍

What is Mobile Observability?

‍

Unfortunately, app failures aren’t linear in distributed systems. The more complex your app, the less predictable it is, making it more challenging to identify known failure modes and metrics to predefine in your monitoring.

This is where mobile observability comes in. Observability compensates for what monitoring can’t do: it tells you your application’s internal state by measuring its outputs, providing you with more robust data points that give you actionable insight into system problems. These data points include traces, logs, and metrics—collectively known as the pillars of observability.

In other words, monitoring is excellent for tracking errors and crashes, but observability tools analyze user sessions, giving you more context about what went wrong and how to avoid it in the future.

For example, monitoring is useful for alerting you as soon as major issues arise. Observability tools, on the other hand, analyze each user session to assess things like device battery, network connectivity, memory usage, and more. All of these are factors that can affect a user’s experience and, to them, seem like a crash or lag.

This is exactly why observability is crucial for mobile app development—unlike web applications, mobile apps operate in highly diverse and constantly changing conditions, from network connectivity to device capabilities and user behaviors.

It’s also important to note that monitoring is only feasible if a system is observable to some degree in the first place. Both tools survey your app for problems, complementing each other and helping you make your software run as smoothly as possible. One provides situational insight, and the other dives into the root causes.

‍

A Brief History of Observability

‍

Observability isn’t a new concept—it predates modern software engineering. It was first introduced by Rudolf E. Kálmán in his control theory, influencing signal processing and various engineering disciplines. Fast forward to today, and the tech industry has embraced observability as a critical approach to understanding complex systems.

Among the first in Silicon Valley to adopt observability were major tech companies, redefining how they track and optimize system performance. While the concept has existed for decades, its importance in mobile and distributed systems has only recently become a cornerstone of modern development.

‍

Key Differences Between Monitoring and Observability

‍

Observability and monitoring have a symbiotic relationship, but it helps to further explore what each does differently to better understand how they work together.

When your system experiences a failure, monitoring answers what happened, and observability answers why. That said, the reason why observability is more of a novelty amongst developers is that it’s possible to monitor almost any application, but observable systems have to be designed as such.

When a system is designed for observability, it not only identifies issues at scale but also provides deep, contextual insights into their root causes. In contrast, monitoring alone is limited to collecting predefined metrics, making it difficult to diagnose complex, unpredictable failures.

Here’s a comparison table highlighting the difference between monitoring and observability:

Aspect Traditional Monitoring Mobile Observability
Focus Reactive detection Proactive Analysis
Scope System performance metrics Complete system behavior understanding
Approach Predefined metrics tracking Dynamic system state analysis
Outcome Issue detection Root cause identification
Data Collection Limited to known metrics Comprehensive telemetry data
Debugging Identifies symptoms Reveals underlying causes
Implementation Works with any system Requires system design consideration
User Experience Limitied visisbility Detailed user session analysis


‍

You can take a deeper look with an observability tool like Instabug, which uses different sources of telemetry to summarize your application’s state. With more context surrounding problems, you can understand why specific requests are failing, how microservices process them, and how they do so differently than expected. The more robust your insight, the more information you have to fix the problem.

Try thinking of an observable system like a house. If something goes wrong with the plumbing or electrical wiring, you don’t need to tear apart the walls to determine what’s happening. Instead, you use visible signs (your “data” in this metaphor) like a backed-up sink or malfunctioning light switch and whatever tools you have—like a pressure gauge or a fuse box—to tell you what’s going on internally.

Walking around your house and checking for problems regularly is akin to monitoring, ensuring you have situational awareness instead of letting issues slide by. Observability is using your tools to find out more information than you can glean just from looking at the problem’s consequences.

You need both monitoring and observability to keep your house running in order. Keeping a sharp eye on its plumbing and electrical functionality—without tearing down the walls—prevents problems from escalating beyond repair, and your investigative tools enable you to find a solution quickly.

‍

The Three Pillars of Observability

‍

As mentioned previously, observability tools collect three types of data, widely known as the pillars of observability. These are:

Metrics

Metrics are aggregated measurements over a given period. They form the basis for monitoring and can reveal long-term patterns like how many requests your app gets per second. You can further divide observability metrics into three types: gauge, delta, and cumulative metrics.

Gauge metrics measure values at particular points in time, such as CPU utilization rates. Delta metrics calculate the difference between a current measurement and a previous one, helping you monitor change. Similarly, cumulative metrics tell you precisely how many changes occurred over a period of time (such as the number of errors in the past hour instead of the difference between the first and last data points).

A streaming app uses metrics to track buffering events across different neighborhoods, helping them identify patterns related to local network infrastructure.

Logs

Entries in a log refer to application-specific events, such as completing a typical task or initiating a process. These entries are time-stamped and unchangeable, providing a record of the goings-on within your system. Logs help you understand why your system behaves unpredictably at times.

When something goes wrong, you can look at the requests that went through at the time of the error and narrow down the source of the problem to the most likely events. Metrics and logs complement each other to give you as much context as possible.

Traces

Traces (or distributed tracing) are beneficial for monitoring performance in distributed systems. Individual microservices often have their own logs and metrics, so following the interactions between them is difficult without a way to display their requests.

Visualizing traces between nodes enables you to track individual requests across complex environments and identify which ones are causing errors and where bottlenecks occur. This is particularly valuable in microservices architectures common in modern mobile apps.

For example, a food delivery app in the Bay Area uses distributed tracing to follow a customer’s order from the initial request through payment processing, restaurant notification, driver assignment, and delivery confirmation, identifying exactly where delays occur in the process.

‍

Why Are Observability and Monitoring Important?

‍

Hopefully, you understand the difference between observability vs monitoring a bit more, but another question is, why bother with either? Are they superfluous to keeping your app running? Definitely not—monitoring and observability tools are essential to maintain a well-functioning app that consumers actually use.

If your app crashes or lags too frequently, users might give up and switch to another. Losing customers is costly, whether you rely on ad revenue or subscription payments. It’s every developer’s nightmare when customers complain in App Store reviews, so the smoother your app works, the better your customer acquisition and retention will be—and that reflects on your bottom line.

However, it’s too strenuous and time-consuming—if not outright impossible—to monitor and observe your app manually (even if you dedicate a whole team of developers), so it’s well worth the investment to have tools operating in the background and keeping closer watch than a human could. For instance, session replay features allow you to replay specific user sessions to understand exactly what happened.

Plus, monitoring and observability tools are especially critical the more complicated your system becomes. It’s unlikely that your app is a monolith; you likely have a host of distributed microservices that have their own needs and frameworks. Consequently, platforms that empower you to debug your system quickly are invaluable.

How AI Enhances Mobile Observability

‍

AI doesn’t just improve mobile observability; it transforms it from passive analysis into proactive, actionable insights. By automatically detecting anomalies, identifying root causes, and even recommending code-level fixes, AI-powered mobile observability eliminates hours of manual debugging. Instead of wading through logs and charts, teams are alerted to what matters most before users ever report a problem.

This shift is especially powerful in mobile environments, where performance issues can be subtle, fragmented, and hard to reproduce. AI helps surface patterns across user sessions, ranks issues by severity and user impact, and enables faster, smarter resolution, all while scaling effortlessly across distributed systems.

AI and machine learning capabilities enhance observability platforms by:

  • Automating time-consuming tasks
  • Providing actionable insights
  • Improving incident resolution times
  • Supporting predictive analytics

With over 80% of enterprises expected to deploy GenAI applications by 2026, organizations must prioritize observability solutions that can effectively monitor and optimize AI implementations.

Implementing Observability in Your Mobile App

‍

When deciding on a platform suitable for you and your app’s needs, it’s essential to pay attention to what it’s capable of: does it offer both performance monitoring and management? What about crash and bug reporting? It’s also essential to keep debugging throughout the development lifecycle, not just once you’ve launched a product and put it into users’ hands.

Here are key steps to implement observability in your mobile app:

  1. Design for observability from the start: Build your app with observability in mind, ensuring you’re capturing the right data points throughout the system.
  2. Implement the three pillars: Ensure you’re collecting metrics, logs, and traces comprehensively across your application.
  3. Choose the right tools: Select observability platforms that integrate well with your tech stack and provide the features you need.
  4. Start with monitoring basics: Build on your existing monitoring infrastructure, adding observability capabilities incrementally.
  5. Focus on user experience: Prioritize observability for the parts of your app that directly impact user experience.
  6. Automate where possible: Use AI and automation to reduce the manual burden of analyzing observability data.
  7. Train your team: Ensure your development team understands how to use observability tools and interpret the data they provide.

Organizations should also focus on cost optimization strategies:

  • Optimizing cloud infrastructure costs
  • Implementing continuous monitoring of infrastructure economics
  • Maintaining performance while achieving cost savings
  • Leveraging platform engineering capabilities

‍

Conclusion

‍

The distinction between mobile observability and monitoring isn’t about choosing one over the other: it’s about understanding how they complement each other to provide a complete picture of your app’s performance. Monitoring tells you when something goes wrong, while observability helps you understand why it happened and how to fix it.
