Monitoring Mobile Applications with Instana

In this blog, we will learn how to monitor mobile applications with Instana.

Introduction

In today’s world, mobile apps form a critical part of the digital experience. Whether you’re providing services, content or internal tools, understanding how users interact and how the app performs is crucial. That’s where observability comes in — and the mobile-app monitoring capabilities of Instana provide a strong foundation to track, analyse, and optimise mobile user experiences.

What Instana Offers for Mobile Apps

Instana supports mobile-app monitoring by analysing actual URL request times, and giving you deep visibility into application call-paths.

Key features include:

• An agent installed in the mobile app (for iOS, Android, React Native, Flutter).
• End-user monitoring (EUM) or real user monitoring (RUM) to understand actual user experience.
• Traffic, crash analytics, view navigation, geographic mapping, custom events and more.

Installing the Agent:

iOS

• Requires iOS 12 or later, Swift 5.4+
• Install via Swift Package Manager or CocoaPods.

Android

• Requires Android 4.1+ (API level 16+), Java 8+, AndroidX, targetSdk 33+
• Use Gradle plug-in plus SDK dependency.

React Native & Flutter

•  React Native: supports both Android & iOS; install @instana/react-native-agent.
• Flutter: supports both platforms; install via pubspec.yaml. Note: HTTP tracing is manual.

Key Monitoring Capabilities:

Dashboard & KPIs:

You’ll get dashboards showing:

• Session starts (when a user launches the app)
• Unique users (or user session identifiers)
• View transitions (when user moves from one screen/view to another)
• Crash-affected session rate and crash-affected user rate — very useful to understand impact.

Performance & HTTP Requests

• Get metrics like app start time, “app not responding”, low memory events.
• Drill into HTTP requests: throughput, latency, error rates, endpoints causing issues.

Crashes

• Crashes are grouped by error type/message; you can view which version, OS, device caused the crash.
• For deeper analysis on iOS you upload dSYM files, on Android mapping files.

Views & Custom Events

• You can isolate individual views/screens and analyse their performance metrics.
• Custom events: you define them; use them to monitor business-relevant flows (e.g., “Purchase Completed”, “User Logged In”).

Analytics & Geo Data

• Instana collects beacon data (session start, HTTP requests) which you can query, filter and group via Instana Analytics.
• It also maps end-user IP addresses to geographic details (city, country) using MaxMind’s GeoIP database.

Why This Matters

For someone administering or monitoring mobile apps (which in your case, with your backend / middleware focus could be a complementary domain), this kind of visibility gives you:

• Real-time detection of performance degradations: e.g., high latency HTTP calls, large un-handled memory usage.
• Better crash insight: identify which users, devices, OS versions are being impacted.
• Business insight: correlate app usage (sessions, views) with backend performance.
• Cross-platform support: whether native iOS/Android or hybrid React Native/Flutter, you have one solution.

Things to Watch / Best Practices:

• Make sure your agent versions are compatible with your platform (OS, framework).
• For React Native/Flutter: note limitations (e.g., Flutter requires manual HTTP tracing).
• For crashes, ensure you upload symbol/mapping files so you get full stack traces.
• Set identity (user ID) when possible so you see unique users rather than anonymous sessions.
• Avoid inhibiting app performance by monitoring: ensure the instrumentation overhead is minimal.
• Because you’re dealing with middleware/infrastructure, ensure your backend services propagate tracing info (e.g., correlation IDs) so end-to-end trace works.

Conclusion

With Instana’s mobile-app monitoring you unlock a critical piece of the observability puzzle — the user’s device. Combined with your knowledge of backend middleware, you can now connect the dots: from a user tapping an app, to the device, to the API call, to your middleware. That gives you stronger insight, faster failures identification, and better optimisation opportunities.
