OCS Drilldowns

Each drilldown page contains displays that provide you with specific information about the components of your system. Drilldowns mainly use two different types of displays – tables and charts. Drilldowns have the following features:

•
They can be configured to show all or some of the metrics associated with components.
•
You can access further information about displays in drilldowns by moving the mouse over the displays, or by clicking or right-clicking on them.
•
You can copy the data shown in drilldowns to other applications or save it to a file.
•
You can view a brief description of a drilldown by hovering your mouse over a component, such as a button, dataflow, status ball, or Toolbar button.
To view a drilldown
•
Right-click a component in a panel and select Show Details.
 
Table 7. OCS drilldowns.

Metrics

A metric is an individual piece of information that UC Diagnostics has collected about the performance of a system, such as perfmon counters. The information may be a numeric value (a number or percentage), a string of text, or some other piece of data.

Each time the UC Diagnostics window is refreshed, UC Diagnostics retrieves the latest value of the metric, which can be displayed in a drilldown or on the home page.

The Metric editor allows you to view and edit the properties of UC Diagnostics metrics, including their thresholds and severities. You can open the Metric editor for a component or a drilldown by right-clicking on the component and choosing Metrics from the invoked shortcut menu.

When you open the Metric editor, the General tab is open by default. Several metrics contain data source descriptions for the metric. The data source descriptions use the following list of functions.

 
Table 8. OCS metrics.
Function
Description

max(x)

the maximum of a set of values in list x

max(x,y)

the maximum of x and y

min(x)

the minimum of a set of values in list x

count(x)

the number of values in list x

sum(x)

the sum of a set of values in list x

if(x,y,z)

if x is true, then return y, otherwise, return z

snull(x)

if x could not be collected, then return true

avg(x)

the average of values in list x

To view the perfmon counters
•
Right-click a component and select Metrics.

The perfmon counter is visible in the Metric help section in the General tab.
