Atlas ITSI Content Pack for Apache Web Server
Overview
Details
The ITSI Content Pack for Apache contains service definitions and KPIs ready to import to ITSI. The KPI Thresholds and importance values are set to defaults so that they can be tuned manually for your use case. After configuration, this content pack provides a comprehensive monitoring solution for Apache web servers.

Services
Apache monitoring encompasses several specialized services, each targeting specific aspects of server performance:
- Apache Web Server
- Description: The primary component responsible for handling HTTP requests and serving web content.
- Request Handling
- Description: Manages the processing of incoming HTTP requests.
- Resource Management
- Description: Manages the allocation and usage of server resources such as CPU, memory, and disk.
- Logging and Monitoring
- Description: Handles the logging of server activities and monitoring of server performance.
- Multi-Processing Modules (MPMs)
- Description: Manages the configuration and performance of different MPMs like prefork, worker, and event.
KPIs
Each service utilizes specific KPIs to measure its effectiveness:
- Requests per Second
- Description: Measures the number of requests handled by the server per second.
- Request Latency
- Description: Measures the time taken to process requests.
- HTTP Errors
- Description: Tracks the HTTP errors returned by the server.
- CPU Usage
- Description: Monitors the CPU utilization of the server.
- Memory Usage
- Description: Monitors the memory utilization of the server.
- Disk I/O and Usage
- Description: Monitors the disk read/write operations and disk space usage.
- Access Logs
- Description: Logs incoming requests to the server.
- Error Logs
- Description: Logs errors encountered by the server.
- Prefork MPM
- Description: Manages the configuration and performance of the prefork MPM.
- Worker MPM
- Description: Manages the configuration and performance of the worker MPM.
- Event MPM
- Description: Manages the configuration and performance of the event MPM.
Relationships
Dependencies:
Services are interconnected; for instance, Apache Web Server is dependent on Request Handling, Resource Management, and Logging and Monitoring. Similarly, Request Handling relies on Multi-Processing Modules (MPMs) and Request Metrics for efficient processing.
Hierarchical Structure:
Some services form a hierarchy, such as Resource Management depending on CPU Usage, Memory Usage, and Disk I/O and Usage, illustrating a layered approach to performance monitoring where base metrics support broader performance indicators.
