 CCMS Selfmonitoring Monitor for Instance-Specific DataLocate this document in the navigation structure


The SAP CCMS Technical Expert Monitors monitor set contains the CCMS Selfmonitoring monitor, which displays the status of the monitoring architecture and of the Alert Monitor. The monitor displays, among other things, whether the Alert Monitor was able to perform the following actions:

  • Start the data collection methods for which it is responsible
  • Assign and access the shared memory that it requires to determine and manage alerts
  • Set up the RFC connections to remote systems and components

Both agents and individual Alert Monitor methods (data collection methods and auto-reaction methods) can display problems and their status in the Selfmonitoring tree.


The CCMS Selfmonitoring monitor consists of multiple subtrees; on the one hand, the system-wide subtree with the title CCMS Selfmonitoring below the relevant system (see CCMS Selfmonitoring Monitor for System-Wide Data), on the other hand, the instance-specific subtrees for the monitored servers and active CCMS agents.


The subtrees MoniInfra_<Name> contain data either about a CCMS agent (SAPCCMSR and SAPCM3X) or about an application server. The structure of the subtree is different in each case, and you should therefore choose your naming convention so that the two types of subtree can be clearly distinguished from each other. We recommend that you use the naming convention <Host_name>_<System>_<Instance-System_number> for your application servers. The names of the subtrees that monitor CCMS agents, on the other hand, have the structure MoniInfra_<Host_name>.

In the case of an application server, the subtree consists of the following monitoring objects:

  • Sapmssy8 (MTE class Sapmssy8)

    This program runs every five minutes on each monitored instance in the context of the AutoABAP SAPMSSY6, starts the local method dispatcher (which is responsible for methods in dialog) and ensures that the properties and methods in the shared memory and the database are reconciled.

    C_Library_Version (MTE class CCMS_Sapmssy8_Version)

This MTE specifies the release of the kernel (and therefore of the application servers) that created this node.

Sapmssy8_Runtime (MTE class Sapmssy8_Runtime)

This MTE specifies the runtime of the program SAPMSSY8, which occupies a dialog work process during its run.

An alert in this MTE indicates that the data collection methods started by SAPMSSY8 are running for too long. This extends the runtime of SAPMSSY8 itself. SAPMSSY8 must not run for longer than five minutes. Otherwise, the next start of the program is before the end of its previous run.

This problem does not normally occur with data collection methods delivered by SAP; however, individual SAP methods could have long runtimes if they have to evaluate large quantities of data (for example: transactional RFC in the case of problems with failed tRFC calls).

Check whether you have included your own data collection methods in the monitoring architecture and whether these methods caused the performance problem. Check the Data Supplier subtree (see below) for error messages or runtime messages.

Runtime alerts from SAPMSSY8 can also be connected with general performance problems. For this, check the Dialog Overview or Entire System monitors.

Sapmssy8_Messages (MTE class Sapmssy8_Status)

This MTE contains messages output by SAPMSSY8. An alert can indicate that the data collection for the monitoring architecture is not functioning error-free. If SAPMSSY8 is terminated due to a data supplier that is not functioning correctly, the program automatically sets this data supplier to the status fatal error, and does not start it again during the next run. SAPMSSY8 should therefore function normally again at the next automatic start.

SAP_Release (MTE class CCMS_Selfmon_SAP_Release)

This MTE contains the valid SAP release of the application server.

Sapmssy8_Version (MTE class CCMS_Sapmssy8_Version)

CCMS uses this version number as an indicator for necessary changes. If a new SAP_DEFAULT properties variant must be generated due to changed data suppliers, CCMS changes the version number in the coding of SAPMSSY8. SAPMSSY8 compares the content of this node with its own version number and creates a new SAP_DEFAULT properties variant if the version numbers are different.

  • Tooldispatching (short running tasks) (MTE class CCMS_Tooldispatching)

    This MTE contains, in the log attribute Messages (MTE class CCMS_Tooldispatching_Messages), runtime messages from the local method dispatcher that starts the methods that are to run in dialog. Methods that are started by this dispatcher can add their own status MTEs, meaning that you can also find runtime and error messages here.


    As the monitoring architecture is an infrastructure with a modular structure, problems in certain methods affect only certain MTEs. The majority of the monitoring functions of the monitoring architecture are not affected by method errors.

  • Data Supplier (MTE class DataSupplier)

    This MTE contains the runtime messages from data suppliers of the monitoring architecture. Depending on the programming of the data supplier, these messages could appear either in the shared log attribute Log or in a separate MTE for the corresponding program. For information about the programming of a data supplier, see "Creating a Data Supplier for the Alert Monitor" in the SAP Service Marketplace under → System Monitoring and Alert Management.

  • CSM (MTE class CCMSSelfMoniCSM)

    If an error occurs while filling or updating the CCMS System Component Repository (SCM) or while comparing a system repository with a central repository, the associated log file message is displayed here.

    As errors of this type are usually only temporary, you should first repeat the operation that failed. If the error persists, contact SAP.

  • Space (MTE class CCMSSelfMoniSpace, see also SAP Note 414029)

    This MTE contains attributes about remaining space in the monitoring segment of the shared memory:

    • Messages (MTE class CCMSSelfMoniSpaceMessages) displays messages from the methods that are assigned to this MTE. If alerts were automatically completed, the system will display a corresponding message.
    • FreeAlertSlots (MTE class CCMSSelfMoni-FreeAlertSlots) specifies the percentage of the memory that is still available.
    • AlertFrequency (MTE class CCMSSelfMoni-AlertsFrequency) specifies the number of alerts per minute.

    If the storage space in the monitoring segment is insufficient, you must increase the shared memory area or complete alerts. You can have the monitoring architecture perform the latter automatically (see Complete Alerts Automatically).


    An analysis method is assigned to all three MTEs with which you can display a precise breakdown of the remaining storage area by alerts and by MTEs and attributes of the various categories.

  • DialogFocus (MTE class DialogFocusSelfMoniClass)

    The performance attribute CountOfReferences shows the number of defined references for client-specific and transaction-specific monitoring. It therefore shows how many clients and transactions you are monitoring separately. This type of monitoring is especially well suited to checking Service Level Agreements (SLA). Use the Transaction-Specific Dialog Monitor to do this.

  • Runtime (MTE class CCMSSelfMoniRuntime)

    This MTE displays problems in the lower layers of the monitoring architecture. Errors during data transfer by RFC are displayed in the log attribute RFC Problems (MTE class CCMSSelfMoniRFC-Problems).


To start the monitor, follow the procedure below:

  1. Start the Alert Monitor using transaction RZ20 or choose CCMS → Control/Monitoring → Alert Monitor.
  2. On the CCMS Monitor Sets screen, expand the SAP CCMS Technical Expert Monitor set.
  3. Start the CCMS Selfmonitoring monitor from the list by double-clicking it.
