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:
The functionality described in this guide is available starting with the following support package levels of the involved Software Components:
Also all systems, which should be displayed in the Emergency Monitoring Dashboard must be configured in the productive Solution Manager with Managed System Configuration and System Monitoring must be activated.
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
The configuration and activation of emergency monitoring contains of 3 different steps.
To activate the emergency monitoring go to https://<solman_fqdn_hostname>:<port>/sap/url/go/diag_agent_admin to access the Diagnostics Agent Administration. Switch there to the tab “Application Configuration” and select the application com.sap.smd.agent.application.wilyhost. There you have to change the value for emergency.monitoring.enable to true in scope “Global".
Restart the Wilyhost application for all Agents by switching on/off the maintenance mode centrally in the Agent Administration.
To allow collection of database metrics via Introscope Host adapter, the following prerequisites must be fulfilled:
To centrally distribute the user and passwords, which has been used to setup the DBACockpit connection in SAP Solution Manager, the ABAP report E2E_EMERGMON_CONFIGURE is available as of SP14, which allows the automatic and selective transfer of the credential information. You have to specify the SIDs of the databases you want to configure and the technical system type (DATABASE for SAP ASE or HANADB for SAP HANA).
Alternatively the information can be stored manually by setting the parameters
For SYB databases using encrypted password handling in JDBC connect the following parameter needs to be specified additionally:
in the Agent Administration for the Wilyhost application on the specific database host scope. All parameters have to be specified with the database name (SID) like <parameter>_<SID>, for example
To enable emergency monitoring the following files are needed (provided as part of the Introscope Management Modules package):
After extraction of the MM package the only manual steps for activation of emergency monitoring should be
You can launch the emergency monitoring application by launching the URL http://<emhost>:<webviewport>/emergmon. Both <emhost> and <webviewport> are the same that you also use e.g. to access Introscope Webview. You will be prompted to enter credentials. The same users as for Webview and Workstation apply here.
The launch screen contains four different tabs: Overview, Systems, Hosts, Databases.
The initially displayed “Overview” tab gives an overview on how many hosts, systems, databases were discovered and displays how many of each are rated red, yellow, or green. The landscape information for this display is directly read from the metric paths in Introscope Enterprise Manager. No additional data sources (e.g. LMDB) are necessary to create Overview Dashboard.
In the System, Database and Host screen on the left side an overview of all known systems, databases, hosts are shown with the overall rating of the Managed Object. After clicking an entry on the left side, on the right side a metric tree with all metrics collected for this managed object is displayed.
Clicking on any of the rectangles will display the list of systems/hosts/databases represented by the number by switching to the appropriate tab and applying a status filter on the table.
The following additional functions are available in the dashboard:
