It is critical to identify tools for executing Technology Availability Management for an engagement. The tools selected for
technology availability, must provide data on unavailability of a component or application.
Monitoring, capturing and recording data pertaining to IT component downtime is a key requirement for reporting, as well as
forecasting for technology availability. Technology availability is generally understood in terms of uptime. It is measured
in terms of the duration for which the service has been available to users, against the committed uptime. This is usually
done by monitoring incidents, problems or events related to technology availablility. Therefore tools which can provide
basic data, such as Incident and Event Management tools, are used. These tools are not specifically provided for Technology
Availability Management, but provide data on the unavailability of a components or applications, and thereby indirectly the
availability of components or applications. Tools also provide data on reliability, as it can provide indication of the
number of failures a component or application has experienced in a given timeframe.
The Availability Manager must determine what has to be measured and how this measurement can be automated. The selected
tool must also be capable of computing and reporting the agreed metrics for technology availability. Modelling tools are
required to forecast technology availability and assess the impact of changes to the IT infrastructure.
The Availability Manager must document the tool requirements and setup the Technology Availabiity Management Tools in
collaboration with the Service Delivery Environment Supervision Manager.
