How To Fix RT125 - Monitoring object: dialog service

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 125

• Message text: Monitoring object: dialog service

What causes this issue?

This monitoring tree element (MTE) reports the response time for the
dialog service. This is the service for interactive processing, as
opposed to the background or the update service.
The dialog response time measures the processing time at the SAP
application server. It includes all processing time consumed for the
processing of a dialog step (starting with a user action and ending with
the system's response to the action), including database processing
time. It does not include network transmission time to the front end or
front-end processing time.
The values that you see here are averaged across dialog steps. You may
therefores ee small variations in the statistics reported here as
compared to those reported in the analysis method associated with this
MTE. This variation is due to the finer granularity of the statistics
in the analysis method. The averaging of the values in the alert
monitor can result in slightly different values.

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?

An alert here indicates a performance problem with your system. Your
users are not receiving the prompt response from the system, as
reflected in the thresholds for response time.
High response times are a general symptom of performance problems. There
can be many different causes of the problem; a careful analysis is
therefore required. You should first check that the application server
is not overloaded, as measured for example by CPU performance, system
paging and dialog work process statistics. Another possible bottleneck
is the database; you should check that the database is performing
satisfactorily.

  Review Configuration: Ensure that the configuration settings for the dialog service are appropriate for your system's workload. This includes parameters like rdisp/num_abap, which controls the number of dialog work processes.
  Analyze Workload: Use transaction codes like ST03N (Workload Analysis) to analyze the workload and identify any bottlenecks or high-load transactions.
  Adjust User Load: If there are too many concurrent users, consider implementing load balancing or scheduling heavy jobs during off-peak hours.
  Check Logs: Review system logs (transaction SM21) for any errors or warnings that could provide more context about the issue.
  Restart Services: In some cases, restarting the affected application server or the entire SAP system may resolve transient issues.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide patches.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM50 (Work Process Overview), SM66 (Global Work Process Overview), and ST22 (Dump Analysis) for monitoring and troubleshooting.
  SAP Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team or SAP support for deeper analysis and resolution.
  Performance Tuning: Regular performance tuning and monitoring can help prevent such issues from occurring in the future.
  
  By following these steps, you should be able to diagnose and resolve the RT125 error related to the dialog service in your SAP system.
