Use

The SAP CCMS Technical Expert Monitors monitor set contains the predefined 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:

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

This graphic is explained in the accompanying text

Note

The monitor consists of multiple subtrees; on the one hand, the system-wide subtree with the title CCMS Selfmonitoring below the relevant system (in the example above, the system CEN), on the other hand, the instance-specific subtrees for the monitored servers and active CCMS agents (see CCMS Selfmonitoring Monitor for instance-specific data). This section provides an introduction to the monitoring tree elements (MTEs) of the system-wide subtree.

Features

The subtree consists of the following monitoring objects:

Methods can, among other things, run in dialog or in background processing. The latter can, depending on the definition of the method, be started by two different dispatchers:
    1. By the periodically-running background dispatcher (SAP_CCMS_BATCH_DISPATCHER)
    2. Also, by the background dispatcher for startup methods (SAP_CCMS_STARTUP_TOOL_BATCH_DP), which runs the methods immediately after the start of a monitoring segment

Both dispatchers run system-wide centrally, rather than on each individual instance, which is why the associated monitoring object is in the system-wide subtree. The dispatcher messages are displayed under Messages.

Methods that are started by this dispatcher can add their own status MTEs, meaning that you can also find runtime and error messages here.

Note

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.

This performance attribute displays the total number of alerts in the alert database. When you complete an alert, it is stored in the database. If the system generates an alert here, the monitoring architecture starts an auto-reaction method that reorganizes the completed alerts and deletes older alerts. You can use the threshold value for this alert to control how many completed alerts are retained.

You can reorganize the completed alerts at any time using the analysis method assigned to this MTE, irrespective of alerts. When doing so, you can specify the date before which all completed alerts are to be deleted.

The monitoring architecture includes various caches in which the assignment of MTEs to MTE classes is stored. These caches accelerate the creation of the monitors and minimize the number of RFC calls required.

Contexts and segments of remote monitored systems are stored in this cache. You can also check this in the Topology Browser of the monitoring architecture.

SAPMSSYT is a data collection method of the monitoring architecture that runs as a job on the monitored systems. During its runtime, the job occupies a work process on the monitored system. SAPMSSYT runs once an hour.

The main tasks of SAPMSSYT are:

You can find SAPMSSYT messages under Messages; SapmssyT_Runtime gives the runtime of the job.

This subtree contains information about the performance database of the monitoring architecture. This database contains performance data that is collected and aggregated in accordance with the user’s specifications. The CollectionRuntime attribute displays the runtime of the job that runs daily to transfer the performance data to the database; CollectionMessage contains possible messages from this job.

This subtree contains the version of the CCMS System Component Repository.

This subtree displays messages from the central method dispatcher (RSAL_CENSYS_TOOL_DISPATCHING) under Messages. This dispatcher makes central auto-reactions possible when alerts are triggered on remote systems. The process of this is as follows:
    1. An alert occurs in the monitored system to which a central auto-reaction method is assigned.
    2. A CCMS agent recognizes the alert and sends the MTE and the alert data to the central system using RFC.
    3. In the central system, the background event SAP_CSM_TRIGGER_CENSYS_DISPATCH is triggered, which starts the central method dispatcher RSAL_CENSYS_TOOL_DISPATCHING. This job calls the corresponding central auto-reaction method in the central system and transfers the information about the MTE and the alert to it. It also adjust the method runtime status in the monitored system using the agent.

For more information about central auto-reactions, see SAP Note 0429265.

This subtree corresponds to the Selfmonitoring CCMS Agents monitor.

Activities

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.
