SAP Server Monitoring


Overview

SAP Monitoring allows you to monitor the availability and performance of SAP environment from a centralized web console. SAP monitor takes advantage of the SAP CCMS (Computer Center Management System) architecture to give insightful information about the SAP system along with fault management and reporting capabilities.

Creating an SAP Server Monitor

Prerequisites for monitoring SAP Server: SAP JavaConnector (JCo) should be present in Applications Manager's classpath. Learn more

Using the REST API to add a new SAP server monitor: Click here

Follow the steps given below to create an SAP server monitor in Applications Manager:

  1. Click on New Monitor. Click on SAP Server.
  2. Provide Host Name/IP Address.
  3. Enter the SubNetMask of the network.
  4. Check the Connect using Router String checkbox to enter the SAP Router String through which SAP Server is connected (optional).
  5. Enter the SAP Logon client.
  6. Enter the SAP System number.
  7. Enter the SAP Logon language like EN for English.
  8. Enter the polling interval time in minutes.
  9. Enter the credential details like user name and password for authentication, or select the required credentials from the Credential Manager list by enabling the Select from Credential list option.
  10. If you are adding a new monitor from an Admin Server, select a Managed Server.
  11. Choose the Monitor Group from the combo box to which you want to associate the Monitor (optional). You can choose multiple groups to associate your monitor.
  12. Click Add Monitor(s). Upon adding the SAP monitor, you can view the details of the newly added SAP monitor.

Note: While creating an SAP monitor, you need an SAP user profile with the following authorization objects: S_RFC, S_XMI_LOG and S_XMI_PROD which are minimum prerequisites for adding an SAP monitor.

SAP RFC Monitoring

Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. The RFC calls a function to be executed in a remote system. Applications Manager monitors metrics pertaining to Queued RFCs (qRFC) and Transactional RFC (tRFC) like:

  • QOUT Scheduler (SMQS) - The QOUT Scheduler processes qRFC outbound queues and controls the sending of qRFC calls. This information can be used to monitor the QOUT Scheduler.
  • QIN Scheduler (SMQR) - The QIN Scheduler processes qRFC inbound queues and controls the processing of inbound qRFC calls.This information can be used to monitor the QIN Scheduler.
  • QOUT Data (SMQ1) - QOUT Data can be used to monitor the Individual qRFC Outbound queues.
  • QIN Data (SMQ2) - QOUT Data can be used to monitor individual qRFC inbound queues.
  • Transactional RFC (SM58) - Every transactional RFC that is executed in a monitored SAP Server  is listed here.
ParameterDescription
QOUT Scheduler (SMQS)
Client The Logon Client.
State The status of the Scheduler at the moment when SMQS is executed. Possible states are: SYSFAIL, CPICERR, INACTIVE, WAITING, WAITCONN, STARTING, ACTIVE.
Time The time of last update.
Group The group to which this scheduler belongs.
Host The host in which this scheduler is running.
QIN Scheduler (SMQR)
Client The Logon Client.
State The status of the Scheduler. Possible states are: SYSFAIL, CPICERR, INACTIVE, RESOURCE LACK, WAITING, BATCH , ACTIVE,STARTING.
Time The time of last update.
Group The group to which this scheduler belongs.
Host The host in which this scheduler is running.
QOUT Data (SMQ1)
Client The Logon Client.
Queue Name The name of the queue.
Destination The target destination of the queue.
State The current state of the queue. Possible states are: SYSFAIL, CPICERR, STOP, SYSLOAD, VBERROR, READY, RUNNING, NOSEND, NOSENDS, WAITING, WAITSTOP, WAITUPDA, RETRY, ARETRY, ANORETRY, MODIFY, EXECUTED, AFINISH, FINISH.
Message The message while executing the queue.
Time The time of last update.
QIN Data (SMQ2)
Client The logon Client.
Queue Name The name of the queue.
State The current state of the queue. Possible States are:SYSFAIL, CPICERR, STOP, READY, RUNNING, WAITING, WAITSTOP, RETRY, ARETRY, ANORETRY, MODIFY, EXECUTED, NOEXEC, AFINISH, FINISH, SAVED.
Message The message while executing the queue.
Time The time of last update.
Transactional RFC (SM58)
Transactional ID The identifier of the Transaction.
Functional Name The name of the function that executed for transaction.
Destination The target destination where this function is executed.
Caller The user who called this transaction.
State The state of the transaction. Possible States are : CPICERR, SYSFAIL, CONFAIL, RECORDED, VBERROR, SYSLOAD, RETRY, ARETRY, ANORETRY, EXECUTED, MAILED, READ, VBRECORD, SENDED, DEBUG, VXRECORD
Message The message while executing the transaction.
Time The time of last update.
Tcode The Tcode from where this transaction is called.
 
Note:

Data Retention: For Transactional RFC, only 2 hours of RAW data will be retained. After two hours the collected RAW data available in Applications Manager database will be deleted. This is because of the HUGE volume of transaction data available in SAP system. Applications Manager database will not scale the huge volume of transaction data.

Data Archiving: Data archiving of transaction data will not happen due to the following reasons.
  • The RAW data is deleted after two hours.
  • Archiving huge volume of transaction data is not a scalable option.

The alert history will be available but no reporting is possible for Transactional RFC.
