How To Fix RT624 - Monitoring attribute: Total CPU usage for a process name

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 624

• Message text: Monitoring attribute: Total CPU usage for a process name

What causes this issue?

Total CPU usage for a process name

System Response

The operating system collector SAPOSCOL determines all running
processes whose names match the specified name pattern. This node
creates the total of the individual percentage CPU usage of all found
processes.
Example:
Name pattern: Process *
Running processes : Process 1 5 %
Process 2 3 %
CPU usage: 8%

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

• What is the cause and solution for SAP error message RT624 - Monitoring attribute: Total CPU usage for a process name ?

  The SAP error message RT624, which refers to "Monitoring attribute: Total CPU usage for a process name," typically indicates that there is an issue related to the CPU usage of a specific process in the SAP system. This message is often encountered in the context of performance monitoring and can be indicative of resource bottlenecks or inefficiencies in the system.
  Cause:
  
  
  High CPU Usage: The primary cause of this error is that the CPU usage for a specific process has exceeded a predefined threshold. This could be due to:
  
  Inefficient code or queries running in the SAP system.
  Background jobs consuming excessive CPU resources.
  System configuration issues leading to suboptimal performance.
  Hardware limitations or resource contention with other processes.
  
  
  
  Monitoring Configuration: Sometimes, the monitoring attributes may not be configured correctly, leading to false alerts or misinterpretation of the CPU usage.
  
  
  Solution:
  
  
  Analyze CPU Usage:
  
  Use transaction codes like SM50 (Process Overview) or SM66 (Global Process Overview) to identify which processes are consuming high CPU resources.
  Check the ST03N transaction for workload analysis to see if specific transactions or background jobs are causing the high CPU usage.
  
  
  
  Optimize Code and Queries:
  
  Review and optimize any ABAP code or SQL queries that are running inefficiently.
  Consider using performance analysis tools like SAT (ABAP Runtime Analysis) or SE30 (Runtime Analysis) to identify bottlenecks.
  
  
  
  Adjust System Configuration:
  
  Review the system parameters and configuration settings to ensure they are optimized for your workload.
  Consider adjusting the number of work processes or the configuration of the application server.
  
  
  
  Monitor Background Jobs:
  
  Check for any background jobs that may be running during peak hours and consuming excessive CPU resources. Reschedule or optimize these jobs if necessary.
  
  
  
  Hardware Considerations:
  
  If the CPU usage is consistently high, consider upgrading the hardware or scaling out the system to handle the load more effectively.
  
  
  
  Review Monitoring Settings:
  
  Ensure that the monitoring settings in the SAP system are correctly configured to avoid false alerts. Adjust thresholds if necessary.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to CPU usage or performance monitoring.
  Performance Tuning Guides: Refer to SAP's performance tuning guides for best practices on optimizing SAP systems.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to diagnose and address the underlying causes of the RT624 error message in your SAP system.
