DCML/ITIL/CMDB Use Cases Ajay Gummadi DCML

Problem • Software Vendor. Co, requests for an audit of Customer. Co’s usage of its server based application Serv. App. • Vendor. Co claims that Customer. Co currently uses more licenses than purchased and hence should purchase more licenses. • Use Case UC 002 at http: //dcml. blogspot. com/ DCML

Customer. Co • CIO of Customer. Co is IT/best-practices savvy • CIO has implemented DCML and ITIL in the organization over a year ago • CMDB reflects the current state of the organization DCML

DCML Architecture DCML

Step 1 • Vendor. Co requests an audit • Requests a list of all instances of Serv. App, running on BSD • Request made via DCML DIX format. DCML

Sample Request <dcml version=“ 1. 0”> <action>audit_request</action> <message_id>1234</message_id> <requestor>Vendor. Co</requestor> <vendor_id>10032</vendor_id> <!– used for identification <request_date>March 23, 2005</request-date> <respond_by_date>March 31, 2005</respond_by_date> <application_name>Serv. App<application_name> <application_name/> <version>6. 2</version> <application_platform>BSD</application_platform> </application> <!– One or more instances of application </dcml> DCML

Sample Response • Message checksum checked • Request acknowledged <dcml version=“ 1. 0”> <action>request_acknowledgement</action> <message_id>1234</message_id> <sender>Customer. Co</sender> <vendor_id>10032</vendor_id> <!– used for identification </dcml> DCML

Step 2: Audit Initiated • DCML Processor generates query for CMDB <dcml version=“ 1. 0”> <message_id>312</message_id> <type>cmdb_query</type> <query>list</type> </dcml> DCML

Step 3: CMDB Response <dcml version=“ 1. 0”> <message_id>435</message_id> <request_id>312</request_id> <type>cmdb_query_result</type> <response> <category>notebooks</category> <category>desktops</category> <category>servers</category> <category>network_hardware</category> <category>telco_hardware</category> <category>PIM</category> <category>Miscellaneous</category> </response> </dcml> DCML

Step 4: DCML PROC. > CMDB <dcml version=“ 1. 0”> <message_id>313</message_id> <type>cmdb_query</type> <query> <search category=“servers”>BSD</search> <search category=applications”>Serv. App</search> </query> </dcml> DCML

Step 5: CMDB Response <dcml version=“ 1. 0”> <message_id>436</message_id> <request_id>313</request_id> <type>cmdb_query_result</type> <response> <results>208</results> <field>Vendor <type>string</type></field> <field>Version</field> <field>Language</field> <field>Service Pack</field> <field>Patch Version</field> <field>Build Versions</field> <field>Install Location</field> <field>IP Address</field> <field>License Key</field> <field>Serial Number</field> <field>Install Date</field> <field>Number of Uses</field> <field>User Name<field> <field>Part Of Suite</field> <field>Date of Last Use</field> </response> </dcml> DCML

Step 6: DCML PROC. > CMDB <dcml version=“ 1. 0”> <message_id>314</message_id> <type>cmdb_query</type> <query> <search_handle>313</search_handle> <fields> <field>IP Address</field> <field>User Name</field> <field>Date of Last Use</field> <field>Number of Uses</field> <field>Serial Number</field> <field>License Key</field> </fields> </query> </dcml> DCML

Step 7: CMDB Response <dcml version=“ 1. 0”> <message_id>437</message_id> <request_id>314</request_id> <type>cmdb_query_result</type> <response> <results>208</results> <row> <value>192. 168. 1. 1</value> <value>jdoe</value> <value>March 22, 2005</value> …. . </row> </response> </dcml> DCML

Step 8: Verification of keys • DCML Processor verifies each license key against CMDB and DSL • License keys are also checked against invoices and receipts (available via CMDB) • DCML Processor seeks clarification from DCML agents and users via DCML DIX and auto-generated XUL/XForms forms • CMDB is updated, with findings. DCML

Step 9: Completion of Audit • DCML Processor generates audit reports • Internal workflow engine routes report to CIO for approval and digital signatures • Approved report is dispatched to Vendor. Co, in DIX format. DCML

Step 10: Post Audit Assessment • CIO has data regarding Serv. App usage • CIO can negotiate better pricing for licenses, using data available from DCML/CMDB • CIO can reallocate unused/sparingly used licenses. • CIO can minimize/eliminate upgrade fees for unused (but installed) instances. DCML

Advantages • • • Accuracy of information Real-time updates Quicker turnarounds Cost savings BSA/SIIA compliance DCML

Advantages (contd…) • Reports : Display by cost center/department/site • Resellers can bid, based on internal usage data (DCML/CMDB Partner. Net) • Powerful reporting (includes historical data) DCML
