1. Built-in Logging System
CodeIgniter includes a logging system located in application/logs, which helps track application events and issues.
The system uses different severity levels to control what gets logged:
| Log Level | Purpose | Typical Usage |
|---|---|---|
| DEBUG | Detailed debugging details | Useful during development |
| INFO | General system updates | Tracks runtime status |
| ERROR | Runtime errors | Logs critical application issues |
| CRITICAL | Severe failures | Captures major system breakdowns |
You can configure logging settings in app/Config/Logger.php for version 4.x or config/config.php for older versions. These settings allow you to define thresholds for the types of messages to log.
Here’s how you might use it:
log_message('error', 'Database connection failed: Connection timeout');
log_message('info', 'User authentication successful');
Log Rotation
To prevent logs from becoming too large, you can enable log rotation. For example, you might set logs to rotate daily and keep them for 30 days.
Security Tips for Logging
- Restrict access: Set proper file permissions to protect log files.
- Avoid sensitive data: Do not log user credentials or other private information.
- Review regularly: Check logs for any potential security issues.
- Store securely: Keep log files outside the public web directory.
To improve logging, you can route critical errors to files while sending debug messages to the browser using handlers. Be mindful of the trade-off between logging detail and performance, especially in production environments.
2. CodeIgniter Profiler Features
The Profiler in CodeIgniter is a built-in tool that helps track performance and debug your application by providing detailed insights. Here’s a closer look at what it offers and how to use it.
Enabling the Profiler
To turn on the Profiler, update your config.php file:
$config['enable_profiler'] = TRUE;
You can also enable it for specific controllers:
$this->output->enable_profiler(TRUE);
Key Profiling Metrics
The Profiler provides a range of performance metrics:
| Metric Type | Information Provided | Usage |
|---|---|---|
| Database Analysis | Query execution times, total queries | Pinpoints slow SQL queries |
| Memory Usage | Peak and current memory consumption | Highlights potential memory leaks |
| Controller Load Time | Execution time per controller | Identifies slow-loading pages |
| View Rendering Stats | Template processing duration | Improves view performance |
Database Profiling Features
To analyze database performance, enable query logging:
$this->db->save_queries = TRUE;
This lets you examine:
- Execution times for individual queries
- Patterns in query frequency
- Resource-heavy operations
- Opportunities to refine and optimize queries
Memory Management Tracking
The memory profiler keeps tabs on resource usage, including:
- Peak Memory Usage: Helps locate memory-heavy processes
- Memory Allocation: Tracks how resources are distributed
- Memory Leaks: Flags inefficient or unoptimized code
Best Practices for Using the Profiler
- Use in Development Only: Enable profiling during development to avoid exposing sensitive information.
- Focus on Critical Controllers: Profile specific areas and review the data regularly.
- Disable in Production: Turn off the Profiler in live environments for security and performance reasons.
You can also add custom benchmarks to track specific operations:
$this->benchmark->mark('my_operation_start');
/* your code */
$this->benchmark->mark('my_operation_end');
The Profiler is a powerful tool for monitoring and debugging CodeIgniter applications. By analyzing its data and applying optimization strategies, you can ensure your application performs efficiently without unnecessary overhead.

3. Inspector Monitoring Platform
Inspector takes CodeIgniter monitoring to the next level with real-time debugging and performance tracking. It integrates directly into your application with no need for complex cloud setups.
Real-Time Monitoring Features
Inspector keeps an eye on your application with these key features:
| Feature | What It Does | Why It Matters |
|---|---|---|
| HTTP Traffic Monitoring | Tracks incoming requests and response times | Helps pinpoint request bottlenecks |
| Slow SQL Query Detection | Flags slow database queries | Improves database performance |
| Background Task Insights | Visualizes asynchronous task execution | Ensures tasks run efficiently |
| Real-Time Error Alerts | Detects runtime issues immediately | Speeds up issue resolution |
Smarter Error Management
Inspector goes beyond CodeIgniter’s standard error tracking. It doesn’t just detect errors – it analyzes them and offers potential fixes. This automated approach helps developers address problems faster and with less guesswork.
Easy Integration
Setting up Inspector in your CodeIgniter project is simple. Just follow these steps:
// Install using Composer
composer require inspector-apm/inspector-codeigniter
// Automatically install the configuration file
php spark inspector:install
// Configure the Ingestion Key in your environment file
inspector.ingestionKey = '974yn8c34ync8xxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
Once integrated, Inspector not only monitors your app but also simplifies team collaboration.
Built for Teams
Inspector’s tiered plans make it great for teams. The free plan supports up to 3 members, while the team plan expands to 5 members – perfect for small to medium-sized groups working together.
