Is there any tools for "Cisco CSS 11506 Content Services Switch CSS11506" to provide performance report?
The enterprise level monitoring and management tool that Cisco makes for this class of device is Application Network Manager (ANM). See http://www.cisco.com/en/US/products/ps6904/tsd_products_support_series_home.html for information.
ANM is probably much more than you need. If you are using the Health and Utilization Monitor (HUM) component of CiscoWorks, your could set it to poll your CSS for MIB variables that are relevant to performance. Alternatively you could use a tool like CACTI or Nagios (open source management products) to do the same.
You can alternatively look at near real time monitoring on a CSS using the Web UI. See http://www.cisco.com/en/US/customer/products/hw/contnetw/ps792/products_tech_note09186a00801e05f5.shtml for setting up this functionality.
Finally, the CSS also has RMON capability. See the RMON and SNMP section of the CSS Administration Guides: http://www.cisco.com/en/US/customer/products/hw/contnetw/ps792/products_installation_and_configuration_guides_list.html
Hope this helps.
