Project Home Page

When you enter the URL to access the browser interface you will start the web application to manage the system. The first page of the web application is the Project Home page. It offers a top-level menu of features you can navigate.



Figure 1. Project Home Page

The six major areas of managing the system are accessible by clicking on the names in the headers of each of the six tables in the display.

Trace

Drill down to see information about the job and file nodes registered with the project. The breadcrumb navigation shows that this view comes from looking at the members of the all-inclusive set, System: nodes. This is the system-defined set that holds all nodes in the graph.

Each node ID in the list provides a link to navigate to the Node Detail page.


Figure 2.

Sets

Sets is a way of grouping nodes in the dependency graph by gathering together nodes that match the selection rules for the set. That group of nodes can be accessed by viewing the members of that set. Each set name in the list provides a link to navigate to the Set Detail page.



Figure 3.

Taskers

This page displays a table listing the taskers with information about the current state of each tasker host. Each row in the table provides links from the group ID and the server host name to see details about each tasker host. The tabs across the top of the System Monitor page lead to other panels showing details about those elements.


Figure 4.

Workload

This table is empty when the system is idle and up-to-date. When the system is running, each row in the table reports on a Job Queue Bucket, which is a grouping of jobs waiting for the same collection of resources. There is one bucket for each unique collection of resources. Jobs in the queue that are waiting for that collection of resources are put into that bucket, along with any other jobs waiting for the same collection of resources.

Resources

Each row in the table provides links to see details about each resource. The tabs across the top of the System Monitor page lead to other panels showing details about those elements.



Figure 6.

Administration

This page is aimed at the Administrator User. You can learn more about the Administrative functions available in this section of the application in the Administrator's manual.

Configuration Parameters
The FlowTracer system uses Configuration Parameters to manage actions and behavior and to constrain various resources. The page showing the set of Configuration Parameters is accessed by clicking Server Config Params from the lower left side on the main page

Adding More Clients
As a user you may reach the maximum number of clients allowed per user with FlowTracer. This maximum number is controlled by the maxNormalClients configuration parameter, which is set to a default value of 400. This configuration control is used to protect against a Denial of Service attack.
You may need to increase this maximum by navigating to the Server Configuration Parameters list and scrolling down to that parameter and increasing the value.
