This blog describes the technical monitoring transactions that must be carried out to support a PI system.  The use of the transactions will enable the “silent running” of the PI system as they will highlight any current issues and detect any problems that may occur in the future. It is envisaged that these transactions will be run by second level support through out the working days on all systems in the production stack landscape unless otherwise specified.  The document also captures the subsequent actions which should be undertaken should problems occur.

The central monitoring of SAP Exchange Infrastructure (PI) offers the option of executing various monitoring activities. Primarily, we use the Runtime Workbench, the central tool for accessing PI monitoring.

Central PI monitoring offers the following options:

  • Message Monitor
  • Communication Channel Monitor
  • Performance Monitor
  • Java Proxy Runtime Monitor
  • Cache Monitor
  • Engine Status
  • IDOC Monitor
  • CPA Cache History
  • Channel-Independent Logs

Message Monitor

Display message processing including aggregated and detailed information about status of messages, identify errors in message processing and perform problem isolation. Manage individual messages by, for example, resending individual message versions.

Message Monitor could be accessed in one of the following ways:

  • Open a browser and go to http://<host>:<port>/pimon to access the Process Integration tools. Then choose Monitoring >> Adapter Engine >> Message Monitor.
  • Click on the Message Monitor
  • In the message monitor, you can access the message overview or search for persisted or archived messages as described below.

Message Status Overview :

  • Message Status Overview will allow you to get a quick overview of the entire message flows sorted by interfaces and status.
  • Overview of Messages and their Statuses shows:

              1. Error

              2. Scheduled

              3. Success

              4. Cancelled

  • Run the transaction for each component is the PI system every hour in the production system.  The transaction should be run once a day in the development and testing systems. (It vary depends upon the project requirements)

Database:

  • Set the time option to cover the last hour for the production system and last day for other systems and access the information by pressing display.
  • Analyze any errors or cancelled with errors and attempt to fix any problems.
  • Run the monitor regularly in the production system.  The transaction should be run once a day in the development and testing systems (It vary according to project requirements).

The Adapter Engine’s Messaging System (MS) receives the message, processes it and forwards it to the receiver. While the MS processes the message, it passes several statuses:

TO_BE_DELIVERED:

  The state of message when it is initially handed over to the   Messaging System.

DELIVERING:

  The state of message when it has popped out of the MS queuing system    and is in the process of being transmitted across the wire or    delivered to an   application.

DELIVERED:

  The state of message when it has successfully reached its intended recipient.

SYSTEM ERROR

  The state of issues with the messages that are flowing through the PI side that can be stuck for several reasons.

HOLDING:

  The state of an EOIO message that cannot be delivered until its     predecessors have been delivered.

WAITING:

The state of a message that has been attempted to be sent at least   once, failed, and is currently waiting for another attempt.

Statuses such as HOLDING or FAILED usually happen only for delivery semantics EOIO (exactly once in order) or BE (best effort).

  System Overview:

  •    Access Availability and Performance->System Overview->System Overview
  •    This gives a broader status of all connected SAP applications(ECC, CRM, SRM) and services.
  •    Status update on Java nodes, database connections, Memory Consumption monitored at one shot.
