Data availability reporting

Data availability or data coverage describes the completeness of data for a report.

Summaries are executed every day that are based on data availability. The summary will run if there is data that is loaded for a period, regardless of the amount of data. No percentage threshold of data availability is used. If there is no data present for the period that is being summarized, then the summary is not initiated. However, summaries can be run to ignore data availability calculations, by executing the summaries on the command line.

You might want to see overall data loading performance at a high level for a few key blocks or data sources. And where there is missing data at a high level, the you must be able to drill down into the lower-level resource instances.

The Tivoli Netcool Performance Manager wireless system includes the data availability feature to facilitate that the system is actually loading data.

The Tivoli Netcool Performance Manager wireless system can load and store this data. However, IBM recommends that monitoring of data availability is concentrated on key resource types and metric groups, which are being used for reporting. Typically, when there is missing data, it is for a whole block or object that is set so this is reflected without monitoring many tables.

After the summaries for a particular technology pack are identified, you must create a data availability Cognos model that contains these summaries and install the Cognos model on Jazz for Service Management.
