    Why monitor Apache?

    Apache HTTP Server is the world's most widely used web server, powering millions of websites. Monitoring Apache is essential to ensure optimal performance, detect bottlenecks before they impact users, and maintain high availability. Xitoring's Apache integration provides deep visibility into your server's health with real-time metrics collection via mod_status.

    Auto-discovery via Xitogent — no manual configuration required
    Real-time metrics from Apache mod_status
    Track request rates, throughput, and connection states
    Customizable alert thresholds for every metric
    Historical data retention for trend analysis
    Works on both Linux and Windows servers
    CLI and dashboard management options
    1-minute metric collection intervals
    Metrics

    What we monitor

    Total Requests

    Total number of HTTP requests processed since the server started.

    Requests per Second

    Current rate of incoming HTTP requests hitting your server.

    Bytes per Second

    Data throughput rate measuring how much data Apache is serving.

    Bytes per Request

    Average response size per request, useful for detecting payload anomalies.

    Busy Workers

    Number of worker threads actively processing requests.

    Idle Workers

    Number of worker threads waiting for incoming requests.

    Connections Total

    Total number of connections accepted by the server.

    Connections Async Writing

    Connections in async write state, waiting to send data to clients.

    Connections Async Keep-Alive

    Connections held open in keep-alive state for potential reuse.

    Connections Async Closing

    Connections in the process of being gracefully closed.

    Server Uptime

    Total time the Apache server has been running without restart.

    CPU Load

    Percentage of CPU consumed by Apache worker processes.

    Triggers & Alerts

    Configurable alert triggers

    Set up custom triggers in your dashboard to get notified the moment Apache metrics cross your defined thresholds.

    Busy Workers

    warning

    Fires when the number of active worker threads exceeds your threshold, indicating the server is under heavy load and may start queuing requests.

    Idle Workers

    critical

    Triggers when idle workers drop below a minimum, meaning the server has little spare capacity to handle incoming traffic spikes.

    Requests per Second

    warning

    Alerts when the request rate exceeds normal baselines, useful for detecting traffic surges, DDoS patterns, or runaway bots.

    CPU Load

    critical

    Fires when Apache's CPU consumption crosses your defined limit, signaling resource contention that could degrade response times.

    Bytes per Second

    warning

    Triggers on abnormal throughput — either unusually high (possible data exfiltration) or low (upstream issues).

    Server Uptime Reset

    critical

    Detects when the server uptime counter resets to zero, indicating an unexpected Apache restart or crash event.

    Importance of Apache Monitoring

    Apache powers over 30% of all active websites globally. Without proper monitoring, performance degradation, traffic spikes, and resource exhaustion can go undetected — leading to downtime, lost revenue, and poor user experience.

    • Detect slow response times before they impact end users
    • Identify memory leaks and resource exhaustion early
    • Prevent cascading failures across your infrastructure
    • Maintain SLA compliance with real-time visibility
    • Correlate Apache metrics with upstream application performance
