 Self-Monitoring of the Central Performance HistoryLocate this document in the navigation structure

Use

You can use the self-monitoring of the Central Performance History (CPH) to monitor the most important functions of the CPH; these include the following data:

  • The scope of the data collection in data records, broken down by the time resolution of the data and by the application servers on which the data is collected
  • Time and duration of the last data collection, broken down by the time resolution of the data
  • Messages about errors that occur during the reorganization, the data collection, or during the automatic report creation; the reasons for these are usually that required jobs have not been scheduled and problems communicating with remote systems
  • Scope, duration, and time of the last automatic creation of CPH reports
  • Scope, duration, and time of the last reorganization of the CPH

You can use the self-monitoring of the CPH both to identify possible errors during the operation of the CPH and to monitor the functioning of the data collection. You can identify how high the workload is during the data collection by monitoring the runtime of the relevant jobs and the number of data records transferred. In the same way, you can monitor the workload due to the reorganization of the performance values and therefore determine the optimal frequency for the various jobs.

Features

The monitor contains the following monitoring tree elements (MTEs):

MTE Description

Data collection

Information about the scope and times of data collection

Remote System: <System ID>

Subtree with the number of data records that were transferred to the CPH with a CCMS agent (see Collecting and Reorganizing Performance Values)

... values pushed by agent

Number of data records, broken down by the resolution (minutes, quarter-hours, and hours)

Total collection info

Scope of the data collection in the local system

Start and end of ... collection

Start and end time of the job that writes the performance values of the relevant resolution to the CPH

Runtime ... collection

Runtime of the job

Collected ... values

Number of data records collected by the job

Server: <Name>

Scope of the data collection in the local system, broken down by the individual application servers

Runtime ... collection Collected ... values

Similar to above, but restricted to the corresponding application server

General CPH status information

Error messages for data collection, reporting, and reorganization (including data collection from remote systems)

CPH error count (collection)

Number of errors during the last data collection run

Data collection message

Data collection error messages; in most cases, either the scheduling for the corresponding job does not exist or is incorrect; or there are communication problems with remote systems or CCMS agents

Reporting message

Error messages for automatic reporting (for reports that are started using the periodic job SAP_CCMS_CPH_REPORT)

CPH error count (reorg/report)

Number of errors that occurred during the last reorganization run or during the automatic report execution

Reorganization message

Error messages for the reorganization of the CPH; in most cases, the scheduling of the corresponding job does not exist or is incorrect

Reporting

Scope and last time of the automatic reporting

Start and end time of report execution

Start and end time of the job that starts the reports that are to be executed in the background

Automatic reporting runtime

Runtime of the job

Number of created reports

Number of reports started by this job

Reorganization

Scope and time of the last reorganization of the CPH

Start and end time of reorganization

Start and end time of the reorganization job

Reorganization runtime

Runtime of the job; depending on the scope of the data collection, the reorganization can create a significant system workload , which is why the relevant job, SAP_CCMS_PERFDB_REORG, only runs once a week by default. If this workload is not critical in your system landscape, you can schedule the job more frequently.

Reorganized objects

Number of data records aggregated during the last reorganization run

Deleted objects

Number of data records deleted during the last reorganization run because the defined retention period was exceeded
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 of monitors by double-clicking it, and expand the subtrees CCMS Selfmonitoring and then Central Performance History in the monitor.
