How To Fix RT054 - CPU: Average usage

SAP Error Message - Details

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 054

• Message text: CPU: Average usage

What causes this issue?

This monitoring tree element (MTE) shows the average utilization of all
of the CPUs in the host system. The utilization includes both user and
system usage of the CPU; it therefore provides a correct view of the
intensity of usage of the CPU and the amount of reserve computing
capacity.
The statistics that you see here may differ slightly from those in the
analysis method for this MTE. This is because of differences in the
sampling rate and sample size between the collection method and the
analysis method. The displayed CPU utilization does not, however,
differ significantly from that reported by the analysis tool.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

A persistently high CPU utilization suggests that the computing capacity
of the CPU(s) are limiting the performance of the system as a whole.
Many factors can contribute to overly high CPU utilization; an analysis
is therefore necessary. If the problem is simply that there are too many
processes active on the host system, then possible corrective measures
include moving CPU-intensive program runs to off-peak times or to other
host systems, dedicating the host system to database use, if it is the
database server, and increasing the number of or upgrading the CPU(s).
Low CPU utilization in conjunction with poor SAP system performance
indicates that there is another bottleneck in the system that is causing
the CPU to wait for long periods.

• What is the cause and solution for SAP error message RT054 - CPU: Average usage ?

  The SAP error message RT054, which indicates "CPU: Average usage," typically relates to performance issues within the SAP system, specifically concerning CPU utilization. This message is often a warning that the CPU usage is higher than expected, which can lead to performance degradation in the system.
  Cause:
  
  High Workload: The system may be processing a high volume of transactions or background jobs, leading to increased CPU usage.
  Inefficient Code: Custom ABAP programs or poorly optimized queries can consume excessive CPU resources.
  Configuration Issues: Incorrect system configuration or insufficient hardware resources can lead to high CPU usage.
  Background Jobs: A large number of background jobs running simultaneously can spike CPU usage.
  System Bottlenecks: Other system resources (like memory or I/O) may be bottlenecking, causing the CPU to work harder.
  
  Solution:
  
  Monitor System Performance: Use transaction codes like ST03N (Workload Analysis) and ST06 (Operating System Monitor) to analyze CPU usage and identify the source of the problem.
  Optimize ABAP Code: Review and optimize any custom ABAP programs or queries that may be consuming excessive CPU resources.
  Adjust Background Jobs: Schedule background jobs during off-peak hours to reduce CPU load during peak times.
  Increase Hardware Resources: If the system consistently runs at high CPU usage, consider upgrading the hardware (CPU, memory) or scaling out to additional application servers.
  Review Configuration: Ensure that the SAP system is configured correctly for the workload it is handling. This may include adjusting parameters in the instance profile.
  Load Balancing: If applicable, distribute the workload across multiple application servers to balance CPU usage.
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may provide specific guidance or patches related to performance issues.
  SAP Community: Engage with the SAP Community forums for insights and shared experiences from other users facing similar issues.
  Performance Tuning Guides: Refer to SAP's performance tuning guides for best practices on optimizing system performance.
  System Monitoring Tools: Consider using SAP Solution Manager or third-party monitoring tools to gain deeper insights into system performance and resource utilization.
  
  By addressing the underlying causes of high CPU usage, you can mitigate the RT054 error and improve overall system performance.
