Figure 8.3: Selecting Parameter Sets with the Wizard

• Load an existing graph conﬁguration from a ﬁle. This allows the user to select a previously saved graph conﬁguration

ﬁle and create a new graph using that conﬁguration.

Selecting the ﬁrst option, “Line graph for a counter or a gauge”, and clicking “Next” displays the graph components screen.

This screen contains a table listing the statistics currently selected for display on the line plot. Initially, this is empty. To add

some statistics click the “Add” button which will display the Select Parameter Set dialog. This dialog allows the user to select

one or more statistics from a parameter set. Using the panel on the left, navigate to the

Events.TestRA

parameter set (Figure

8.3).

Using shift-click, select the counter type statistics “accepted”, “rejected”, “failed” and “successful”. If the intention is to extract

statistics from the multi-node Rhino cluster then this screen can be used to select an individual node to extract the statistics from.

In this case, opt to use combined statistics from the whole cluster. Click

to add these counters to the graph components screen

(Figure 8.4).

On this screen, the colour assigned to each statistic can be changed using the colour drop down in the graph components table.

Clicking Next displays the ﬁnal screen in the graph creation wizard. On this screen, assign a name to the graph and select a

display tab to display the graph in (Figure 8.5).

By default all graphs are created in a tab of the same name as the graph title but there is also the option of adding several related

graphs to the same tab for easy visual comparison. For this exam ple, the graph has been named “TestRA Events from Cluster”

and displayed in a new tab of the same name. There is no need to ﬁll out the tab name ﬁeld to use the same name for the tab

name.

Clicking Finish will create the graph and begin populating it with statistics extracted from Rhino (Figure 8.6).

The

rhino-stats

client will continue collecting stats periodically from Rhino and adding them to the graph. By default the

graph will only display the last one minute of information - this can be changed via the graphs context menu (accessible via

right-click) which allows the x axis scale to be narrowed to 30 seconds, or widened up to 10 minutes. Each line graph will store

approximately one hour of data (using the default sample frequency of 1 second). Stored data that is not currently visible can

be reviewed by clicking and dragging the graph, or clicking on the position indicator at the bottom of the graph.

8.4.1 Saved Graph Conﬁgurations

Because it can be quite time consuming to create graphs with multiple statistics the

rhino-stats

client allows saving of graph

conﬁgurations to an XML ﬁle. To save the conﬁguration of a graph right click on the graph to display it’s context menu and

select “Save Graph Conﬁguration”.

There are two ways to load and display saved graph conﬁguration;

1. By using the -f command line parameter when starting the

rhino-stats

client.
