Summary

The percentage of CPU usage for the Apache HTTP Server is high. System performance may be adversely affected.

Total CPU percent is the amount of CPU resources the Apache HTTP Server is consuming compared to the total CPU resources available. The Apache HTTP Server utilizes the processor when it services incoming requests. This metric is the primary indicator of Apache HTTP processor activity, and displays the average percentage of busy time observed.

The monitor threshold is analyzed against an average of values returned in polls to the agent where the Number of Samples parameter controls the number of samples included in the calculation of the average.

Causes

An unhealthy state indicates that the processor utilization by the Apache HTTP Server is currently high. This may be caused by a very high number of requests or the processing cost of the web application itself.

Resolutions

To address high Apache HTTP Server CPU usage choose one or more of the following options:

  • Identify files that the Apache process might be using by running the lsof –p [apache-process-id] command.

  • Add processors or physical memory to the computer.

  • Move applications to one or more additional servers.

  • Investigate the efficiency of the web applications
