Emergency Monitoring
During maintenance of the productive SAP Solution Manager it is necessary to provide monitoring for the managed system landscape as emergency monitoring scenario. This needs to be provided to ensure that during a planned or unplanned maintenance of the SAP Solution Manager system, the 1st and 2nd level support has tools to monitor the managed system landscape manually. To achieve this solution the SAP Diagnostics Agents and the CA Introscope are used to provide monitoring during downtimes of the central SAP Solution Manager system.
The monitoring of the system landscape is provided via a specific dashboard deployed on CA Introscope as part of the SAP Management Modules for CA Introscope.
To provide the necessary content for the dashboard, the following data collection infrastructure is used:
- Channel 1: is the data collection of performance metrics from ABAP based system via specific ST-PI data collection modules. This data is read by the wily host agelet in the SAP Solution Manager Diagnostics Agent. The collected data is mapped to Introscope metric paths and transferred to Introscope Enterprise Manager.
- Channel 2: the wily host agelet subscribes as additional receiver to some predefined metrics collected by the MAI agelet in the diagnostics agent (as configured by system monitoring). The metrics are mapped to specific Introscope metric paths and transferred to the Introscope Enterprise Manager.
- Channel 3: the wily host agelet is enhanced by a JDBC collector, which connects locally to the database system running on the same host with the monitoring user provided in the Managed System Configuration and reads a defined set of metrics from the database monitoring views. The metrics are mapped to specific Introscope metric paths and transferred to the Introscope Enterprise Manager.
- Channel 4: the Introscope byte code injection agent is deployed in the J2EE engine. Data is mapped to Introscope metric paths and sent by the byte code agent to the Introscope Enterprise Manager. There are no changes to this existing channel required for emergency monitoring.
Prerequisites
The functionality described in this guide is available starting with the following support package levels of the involved Software Components:
- Introscope Enterprise Manager: 9.7 or higher
- SAP Management Modules for Introscope: 9.7 or higher
- SAP Solution Manager: 7.1 SP14 or 7.2 SP1
Also all systems, which should be displayed in the Emergency Monitoring Dashboard must be configured in the productive SAP Solution Manager with Managed System Configuration and System Monitoring must be activated.
Restrictions
The monitoring content shown in the dashboard is not fully configurable, this means only a fixed set of metrics per system/database type is defined and thresholds could not be adjusted per system individually.
