SAP NetWeaver Process Integration (PI) is SAP's implementation of Service-Oriented Architecture (SOA) middleware service bus. It facilitates the integration of business processes that span different software components, departments, and organizations. Since Process Integration server is the heart of integration in an enterprise, it is very important to maintain high availability of the system for uninterrupted data exchange across the landscape.
Central PI monitoring in SAP Solution Manager provides unified alert notifications, exceptions and status of PI components from a single-entry point. It also provides options to navigate to details of such exceptions in the respective host system. It becomes easier for addressing the issues more quickly and efficiently.
Please note that Central PI Monitoring in SAP Solution Manager 7.2 is generally available for PI domains, where the Integration Server is running SAP PI 7.11 or higher!
Continuous Business Availability – Centralized monitoring of PI domain helps to accelerate the problem resolution process. This leads to high availability of Process Integration server and the data exchange between the systems are uninterrupted, hence the high availability of the application.
Central Entry Point – Growing PI landscape complexity and distribution leads to growing requirements towards a central monitoring approach.
Reduced TCO – Simplification of operations processes by providing one single entry point for all component monitors for overall PI domain status. Additional drill down option provides detailed information up to the host level. This reduces the overall problem resolution time and the number of resources involved in the investigation of issues.
Integration – Tightly integrated with other SAP Solution Manager tools such as System Monitoring and Root Cause Analysis, Alerting Infrastructure, Notification, and Incident Management.
Production Resources Freed – Central collection of monitored data relieves the production system from additional burden of monitoring.
Self Check – Self-check feature provides availability of monitored components.
Message Monitoring – Operations support must be able to monitor and query all interfaces based on the date and time triggered, the sender and receiver systems, processing time, errors (if any), and other attributes. Messages will need to be uniquely identified so that they can be traced easily.
Payload Query – The system administrator and any other relevant business/support personnel should be able to query messages based on the contents of the payload. For example, search for messages that have been sent to a procurement system by the Purchase Order Number or Vendor ID within a given date & time interval.
The new Central PI Monitoring in SAP Solution Manager 7.2 supports SAP PI Administrators, Application Support Users, and Operation Control Center Users to monitor theirs PI Landscapes. The main use cases are as follows:
Available features for SAP Solution Manager 7.2 Central PI Monitoring depending on PI system release. All the features mentioned in older releases are included in the newer ones.
Example: SAP PI 7.31 would have Central User-Defined Search and Enhanced Component-Based Message Alerting plus all the features indicated for SAP PI 7.11 releases.
|SAP PI 7.11+||SAP PI 7.31+||SAP PI 7.4+||SAP PI 7.5+|
Managed System Configuration for all managed systems that are part of the PI Domain is a prerequisite for PI monitoring use case. You configure the managed systems in SAP Solution Manager Configuration under Managed Systems Configuration using the Full Configuration Mode. Configuring managed systems is a series of steps. For more information on each step, see the detailed help documentation in SAP Solution Manager Configuration.
Monitoring solutions focus on technical scenarios. A technical scenario corresponds to a PI Domain with its PI components. As a prerequisite you need to create an SLD destination for which the PI Domain information (central SLD or a local SLD) is required.
For more information on Creation of SLD, see SAP Solution Manager Configuration (transaction SOLMAN_SETUP) → Mandatory Configuration → Infrastructure Preparation → Set Up landscape Management → SLD Connections.
Note: The SLDs that you create in SAP Solution Manager 7.2 should be the same as the SLDs maintained in SAP Solution Manager 7.1 including protocol, host, and port or else the content activation will fail.
Note: While creating the SLD Connection, SLD Role must be of type PI SLD.
After creation the SLD, choose Save in Step 1.1 (SLD Connection) before moving to the next step
The PI domain with all its PI components must be known to SAP Solution Manager for central PI Monitoring. PI domain is modelled as Technical Scenario of type PI Monitoring in LMDB. You configure the PI monitoring in SAP Solution Manager configuration under Application Operations → Integration Monitoring → Process Integration. PI monitoring setup is a series of steps. For more information on each step, see the detailed help documentation in SAP Solution Manager Configuration.
Relevant SAP notes must be implemented in your SAP Solution Manager system to make sure PI Monitoring works flawlessly. The required notes depend on your SAP Solution Manager support package. Useful troubleshooting guides are included for your reference. More information can be found in the SAP Note 2625154: Notes, troubleshooting guides and additional information for Central PI Monitoring.
To be able to use PI Monitoring with SAP Solution Manager you need at least SAP PI 7.11 SP06.
If you plan to use Message Based Alerting and Central User Defined Message Search please note that this is only available with a PI release of 7.31.
Supported in PI Release less than 7.11 SP06

In SAP Solution Manager you find messages with the status FORWARDED. This status does not exist in the single systems on the PI domain. You want to know what it means.
As SAP Solution Manager collects information from all components in the PI domain in the Central PI Message Monitor, the message status overview is displayed for entire PI domain and not only for one component (as is would be in the traditional distributed PI monitoring approach). But this means, if you count successful messages, they are counted in each component and as a sum you will receive the number of successfully counted messages (All successful messages in all components, even if a message was successful in 2 components). This is not the total number of messages in the PI domain, it could be more.
To avoid this discrepancy, the status FORWARDED was introduced, locally on SAP Solution Manager only. This status means, a message was successful on one PI component, it was passed to another PI component, but it did not yet reach its ultimate target and passed the PI domain successfully. In the single components of the decentralized traditional PI monitoring this distinction is not necessary as you do not have an overall overview over messages in other components. In SAP Solution Manager this status was needed to mark a not-finished but so far successful PI message.

This page describes the procedure to migrate Central Process Integration Monitoring from SAP Solution Manager 7.1 to SAP Solution Manager 7.2. It indicates the requisites, which elements are migrated and which not and the steps to achieve a successful migration.
During Central Process Integration Monitoring setup:
As indicated in the help text, you need to execute this step if you are planning for content activation for PI Monitoring and Message Flow Monitoring. For content activation, PI Monitoring and Message Flow (MF) Monitoring need to be already configured in 7.1.
IMPORTANT: You shouldn't perform this step, if you are planning to set up MF Monitoring and PI Monitoring for SAP Solution Manager 7.2 from scratch, just skip it. In case you execute the step without performing a migration (PI Monitoring setup from the scratch), you'll see the error “No PI Domains configured with SLD” in "Basic PI Configuration" automatic activity at step “2.6 Configure Automatically” in PI Monitoring setup. This error message is not relevant at all, just skip this step as indicated before.
Further information about Central Process Integration Monitoring migration.
2. INFORMATION MIGRATED
The following information is migrated when performing the automatic activities in step 2.6 "Configure Automatically":
A) Domain Maintenance.
B) All automatic activities in "Load Meta-Data" step.
