Introduction

The server-status page is a powerful tool for monitoring real-time server performance. This article breaks down the key components and metrics presented on the server-status page.

You can check this KB for enabling Server-Status and managing login details of Server-Status in DirectAdmin by using CLI: https://www.ipserverone.info/knowledge-base/enabling-server-status-and-managing-login-details-in-directadmin/

Apache Server Status Breakdown

• Server Version: Shows the Apache server version and the version of OpenSSL it’s compiled with.
• Server MPM: Displays the Multi-Processing Module (MPM) used, which determines how client requests are handled.
• Current Time: The current time on the server.
• Restart Time: The last time the server was started or restarted.
• Parent Server Config. Generation: Number of times the server configuration has been reloaded.
• Server Uptime: How long the server has been running since the last restart.
• Server Load: The load average of the server, representing the workload the server is under.
• Total Accesses and Traffic: The total number of accesses (requests) to the server and the total data transferred.
• CPU Usage: The CPU time used by the server.
• Requests per Second, Bytes per Request, and Bytes per Second: Metrics to gauge the traffic intensity and throughput.

Worker Status Table

• Slot: The worker slot number.
• PID: Process ID of the worker.
• Stopping: Whether the worker is in the process of stopping.
• Connections, Threads, Async connections: Various counters for the number of connections and threads, including those that are idle, writing, in keep-alive, or closing.

Breakdown of Request Handling Metrics

• Srv: The child server number corresponding to the request being processed.
• PID: The process ID of the worker serving the request.
• Acc: Three values related to the connections that a particular worker process has handled. They are usually separated by forward slashes (/). Here’s what each part stands for:
  • Number of Accesses: This is the first number and it shows the total count of accesses or requests that the worker process has served since it started.
  • Mode of Operation: The second number indicates the mode of operation of the worker (e.g., reading, writing). In some configurations, however, this might not be represented as a number but as a letter code.
  • Bytes Served: The third number represents the total number of bytes that have been served by this child worker.
• M: The mode of operation of the worker: Waiting for Connection, Starting up, Reading Request, Sending Reply, Keepalive (read), DNS Lookup, Closing connection, Logging, Gracefully finishing, Idle cleanup of worker,
• Open slot with no current process.
• CPU: The CPU time consumed by this request.
• SS: Seconds since the beginning of the most recent request.
• Req: Milliseconds required to process the most recent request.
• Dur: The duration in microseconds of the request.
• Conn: The connection count for this child server.
• Child: The child process number.
• Slot: The slot number in the scoreboard.
• Client: The IP address of the client making the request.
• Protocol: The protocol used (HTTP/1.1, HTTP/2, etc.).
• VHost: The virtual host that was requested.
• Request: The specific request made by the client.

Understanding Request Details

The details provided in this table are instrumental in managing the web server’s performance. For example:

• High CPU Usage: May indicate a resource-intensive script or application.
• Long Request Duration: Could suggest that a script is slow to execute or is waiting on external resources.
• Repeated Specific Requests: Could potentially be a sign of an automated attack or a misconfigured script.

Conclusion

The server-status page is an essential tool for monitoring and optimizing server performance in DirectAdmin. Understanding its metrics allows for better management and troubleshooting.
