Step 2: Audit Initiated

DCML Processor generates query for CMDB<dcml version=“1.0”> <message_id>312</message_id> <action>cmdb_query</action> <query>list</type></dcml>


Step 3: CMDB Response

<dcml version=“1.0”> <message_id>435</message_id> <request_id>312</request_id> <action>cmdb_query_result</action> <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>


Step 4: DCML PROC. > CMDB

<dcml version=“1.0”> <message_id>313</message_id> <action>cmdb_query</action> <query> <search category=“server”>BSD</search> <search category=“application”>ServApp</search> <search category=“version”>6.2.*</search> </query></dcml>



<dcml version=“1.0”> <message_id>436</message_id> <request_id>313</request_id> <action>cmdb_query_result</action> <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>

<field>Install Date</field> <field>Number of Uses</field> <field>User Name<field> <field>Part Of Suite</field> <field>Date of Last Use</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> </response></dcml>


Step 6: DCML PROC. > CMDB

<dcml version=“1.0”> <message_id>314</message_id> <action>cmdb_query</action> <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 version=“1.0”> <message_id>437</message_id> <request_id>314</request_id> <action>cmdb_query_result</action> <response> <results>208</results> <row> <value>192.168.1.1</value> <value>jdoe</value> <value>March 22, 2005</value> ….. </row> </response></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.


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 VendorCo, in

DIX format.


Step 10: Post Audit Assessment

CIO has data regarding ServApp 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.


Advantages

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


Advantages (contd…)

Reports : Display by cost center/department/site

Resellers can bid, based on internal usage data (DCML/CMDB PartnerNet)

Powerful reporting (includes historical data)
