Blansh GUI Managed Elements Status Tree
Managed Elements Status Tree
Clicking a Managed Elements Branch leaf will run a query to retrieve all the subordinate elements belonging to the top node of the <Managed Elements>. This node is a top for this tree. This functionality is accessible to the TECHNICIAN or ROOT authorization levels.
Process of building the Tree is done in such a way as to minimize number of System queries for each operator's input. This implies that clicking on the top node of Managed Elements Branch will only query and show the immediate subordinates belonging to the top node.
Subsequent clicking on the revealed leaves will query and show the next level of elements dependency and so on until the final leaf which does not have subordinates. This is a manual traversal tree. In the previous stages of our design for the GUI Managed Elements Status Tree we had an automatic <one shot query> for all the Managed Elements. But this method appeared to be a heavy load and slow on the large system with large number of Managed Elements.
Below is a screenshot of the Managed Element Status Branch expanded.
Node information
Each node of the Managed Element Tree has icon and text information.
Icons for each node of the Tree provide dependancy as well as status information with following meanings for each icon:
not expanded node element containing subordinates, status of this
element OK
expanded node element containing subordinates, status of this
element OK
not expanded node element containing subordinates, status of this
element NOT OK
expanded node element containing subordinates, status of this
element NOT OK
leaf element, status OK
leaf element, status NOT OK
Text information for each node has a Title and a Status information for the element. Title represented in form of the table name and index number. For ex. <modem-18> consists of the table name <modem> and this element's index 18 . Status for the element is provided in the text form which is defined by a particular element, for ex. <present/not present> <connected/not connected> <OK/not OK>, etc.
Assumption is made in this design that status per node/element reports only about this node/element, and does not necessarily provide any hint about status of the subordinate elements.
Element Update Dialog
Double click on any node/element will bring up an Element Update Dialog screen. It is similar to other Update Dialog screen described in other sections of this document. The only exceptions are that this dialog does not have a <Select Query> button because it manages only one chosen element. Also this dialog does not have any customizations, all the fields provided as a text field.
Following operations can be performed:
Update text fields and click <Update>. After making all the updates you can verify the content of the database by running a <Refresh> on the Table screen.
Insert a new row into the database after entering all the fields.
Close Dialog.
Note: Final update will only be completed when clicking either <Update> or <Insert> buttons of the Element Update Dialog screen.
All changes done by user are confirmed by the messages in the browser status field.
