HAI Use Case: Examine BES processes/connections

From OPeNDAP Documentation

Point Of Contact: Nathan Potter

1 Description

The Administrator uses the HAI to choose a BES and then view a list of its current processes/connections.

2 Goal

To allow the Administrator to see, for each BES in use with a particular Hyrax instance, how many processes/connections the BES has open.

3 Summary

Once logged into the HAI the Administrator selects a BES that's connected to the instance of Hyrax that is being managed. The page (or part thereof) returned for the selected BES shows all of the processes/connections that the BES has running or is servicing.

4 Actors

  • Administrator
  • Hyrax
  • HAI

5 Preconditions

The Administrator has an authentication privileges for an HAI.

6 Triggers

The Administrator wants to see the list of processes/connections for a particular BES.

7 Basic Flow

  1. The Admin logs into the HAI
  2. The Administrator the HAI to navigate one or pages to select a BES associated with Hyrax instance of the HAI.
  3. Once selected the Admin can see the processes/connections in use by the BES.
