Chapter 58 Performance Monitoring
Historical Performance Monitoring
Generating Top10 Reports in Performance Manager
You can generate historical Top10 reports that can be saved for later review. These reports list the entities
from the data collection, with the most active entities appearing first. This is a static, one-time only
report that generates averages and graphs of the data collection as a snapshot at the time the report is
generated.
Tip Name the reports with a timestamp so that you can easily find the report for a given day or week.
These Top10 reports differ from the other monitoring tables and graphs in Performance Manager in that
the other data is continuously monitored and is sortable on any table column. The Top10 reports are a
snapshot view at the time the report was generated.
Note Top10 reports require analyzing the existing data over an extended period of time and can take hours or
more to generate on large fabrics.
See the “Creating a Custom Report Template” section on page 7-37 for information on creating a Top10
report.
Generating Top10 Reports Using Scripts
You can generate Top10 reports manually by issuing the following commands:
• On UNIX, run the script:
“/<user_directory>/.cisco_mds9000/bin/pm.sh display pm/pm.xml <output_directory>”
• On Windows, run the script:
“c:\Program Files\Cisco Systems\MDS 9000\bin\pm.bat display pm\pm.xml
<output_directory>”
On UNIX, you can automate the generation of the Top10 reports on your Fabric Manager Server host by
adding the following cron entry to generate the reports once an hour:
0 * * * * /<user_directory>/.cisco_mds9000/bin/pm.sh display pm/pm.xml <output_directory>
If your crontab does not run automatically or Java complains about an exception similar to
Example 58-1, you need to add “-Djava.awt.headless=true” to the JVMARGS command in
/<user_directory>/.cisco_mds9000/bin/pm.sh.
Example 58-1 Example Java Exception
in thread “main” java.lang.InternalError Can't connect to X11 window server using '0.0' as
the value of the DISPLAY variable.
Exporting Data Collections to XML Files
The RRD files used by Performance Manager can be exported to a freeware tool called rrdtool. The rrd
files are located in pm/db on the Fabric Manager Server. To export the collection to an XML file, enter
the following command at the operating system command-line prompt:
/bin/pm.bat xport xxx yyy
