Environment

NetIQ Operations Center 5.0 PB8

Situation

This TID explains some expected behavior for the Dashboard's Charting portlet and charting in the Information Portlet.

Resolution

Missing Metric

 

Metrics can be missing from a chart for the following reasons:

 

  • A metric is deleted in the management system (for example , AppManager)
  • A service model is deleted in Operations Systems and its metrics are no longer accessible
  • An adapter is offline

 

When any of the above happens, the following occurs in the Charting portlet:

 

  • The metric disappears from the chart and the element/metric name(s) are removed from the Basic tab in the left configuration panel.  If the page is manually refreshed, the metric shows with a red (!) icon.
  • A red  (!) icon displays next to the metric in the Manage Elements wizard.

When any of the above happens, the following occurs in the Information portlet:

 

  • The metric disappears from the chart.
  • The metric continues to display in the metric selector list until the page is refreshed.

 

Charting Count Metrics (Child Condition Counts & Alarm Severity Counts)

 

In order to chart metrics providing a count-type summary (Child Condition Counts, Alarm Severity Counts), the chart must reserve 7 metric slots when allocating room in the chart and before adding any more metrics. Therefore, because we limit the chart to 10,  in this instance the chart can only include 1 count metric and 3 non-count metrics...for a total of 4 metrics. A Not all metrics appear  message displays at the bottom of the chart.
