4.4.2 Checking past data
You can check performance charts of a monitored service's past performance and use the information for root cause investigation.
If you find a warning sign in a performance chart or were contacted by users of a monitored service, you can check the monitored service's past service performance data as necessary.
If you link with Performance Management, you can also check the past data of the system, such as the host or middleware, that is providing the monitored service.
This subsection explains how to check past service performance only using the Troubleshoot window.
- Organization of this subsection
(1) Before you start
-
Before you start SLM - Manager, specify the URL of PFM - Web Console in SLM's system definition file. For details about the settings in the system definition file, see 5.4 Setting up a linkage between SLM and Performance Management.
Log in to SLM - Manager.
For details about how to log in, see 2.2.1 Logging in to SLM - Manager.
Verify that monitoring has started.
For details about how to start monitoring, see 4.2.1 Starting monitoring.
-
If you link SLM with Performance Management, verify that PFM - Manager is running. For details about how to start PFM - Manager, see the JP1/Performance Management Planning and Configuration Guide.
-
If you link with Performance Management, verify that the prerequisites for PFM - Web Console are satisfied. For details about the prerequisites for PFM - Web Console, see the JP1/Performance Management Planning and Configuration Guide.
(2) Procedure
Troubleshoot window
Troubleshoot window (with the configuration information displayed)
-
Troubleshoot window (with the access log displayed)
To check past data:
Click the Troubleshoot button.
The Event and Performance chart tabs area is displayed with the Event tab selected.
In the Event and Performance chart tabs area, click the Performance chart tab.
Performance charts of monitored targets of the selected monitored service are displayed in the Event and Performance chart tabs area.
Use the performance charts to check past service performance.
Check the performance charts and look for a time period during which the average value for service performance started to veer significantly from the baseline. On a performance chart, a colored band indicates a timeframe during which a significant change in service performance occurred. The timeframe indicated by the colored band might be when the event causing the error or warning occurred.
Click to display configuration information and add to the performance charts any monitoring item that you want to check.
Display the configuration information and select a desired monitoring item. The performance chart for the selected monitoring item is displayed. Check the performance charts as needed.
If SLM is linked with Performance Management, you can locate erroneous hosts in the SLM window, but not erroneous processes. Also, if errors and warnings have occurred in a Performance Management monitoring item that cannot be monitored by SLM, SLM cannot display such errors and warnings. Log in to Performance Management as needed to check for errors. Clicking the button displays the Performance Management login window. Log in to Performance Management using the user name you used for login to SLM.
If you use a single sign-on to log in to Performance Management, the following conditions must be satisfied:
-
SLM - Manager and PFM - Web Console both use JP1/Base authentication and a common JP1/Base to manage users.
-
The user of the product to link with is defined in JP1/Base, and SLM - Manager operation permission (JP1_ITSLM_Admin or JP1_ITSLM_User) and PFM operation permission (JP1_PFM_Operator) are set for that user. For details, see 5.3.4 Setting up the users who will be using Performance Management (JP1 authentication mode).
-
The user of the product to link with is logged in to SLM - Manager.
-
-
Click to display the Access log area to investigate problems in Web system processing.
If you are recording access log, click to display the Access log area.
You can then investigate any problems in Web system processing using the access log for the time period during which the error occurred.
You can use the displayed past service performance for troubleshooting purposes.
You can display the Troubleshoot window also from the Real-time Monitor window. To do this, select the monitored target of the monitored service in the Services area of the Real-time Monitor window, and then click the Performance chart tab.
In the Event and Performance chart tabs area, clicking the Troubleshoot button displays the Troubleshoot window.
