Purpose
Currently the navigation widget in the COMOSUI provides a mechanism to submit CMDBf queries to MDRs. These queries are constructed by the end user and are not persisted. As a result the queries are lost once the COSMOS UI application shutsdown.
Requirement
This enhancement proposes a mechanism for developers to register predefined cmdbf queries with the data visualization user interface.
The following illustrates a query that is useful against a statistical MDR:
I want the memory usage data for the machine that is running the tomcat 59223 server?
A CMDBf query file would be created to capture the above query. A registry is needed to associate this query with a specific MDR that contains the information.
The following illustrates how the navigation tree will present predefined queries.
+MDR (Asset Repository) +MDR (Monitoring Repository) +MDR (Statistical Repository)
+ Tomcat Server 5912334
+ All Statistical data from 12/2/2003 to 12/2/2004
+ All Statistical data from 12/2/2004 to 12/2/2005
+ All Statistical data from 12/2/2005 to 12/2/2006
+ Memory Usage
+ Websphere Server 55224
+ All Statistical data from 12/2/2003 to 12/2/2004
+ All Statistical data from 12/2/2004 to 12/2/2005
+ All Statistical data from 12/2/2005 to 12/2/2006
Note the above shows a "query tree". The "MDR (Statistical Repository)" contains two top level queries that will query for statistical data based on the server id. In contrast, each of these queries contain nested queries that
filter the queries further by date. Note that this query tree defines away to organize the queries for a particular mdr. Developers would create the corresponding cmdf query files to construct this query tree. A registration mechanism is required in the data visualization component to recognize these cmdbf file and present this queries in the navigator view.
Meta data information should be associated with a query file that describes the query. Tagging this file would also be useful. The meta data file should also contain management rules that will match the data manager that this query should apply to.
