Subject [jira] [Commented] (PIVOT-1031) Create a new "gauge" object which can display a single value in a circular "speedometer" fashion
Date Mon, 26 Feb 2018 23:52:00 GMT

    [ https://issues.apache.org/jira/browse/PIVOT-1031?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16377805#comment-16377805
] 

Roger Whitcomb commented on PIVOT-1031:
---------------------------------------

Adding to the Component Explorer, but many things had to change:
 * Fix BeanMonitor and EventLogger to deal with the parameterized GaugeListener type.
 * Rework the GaugeListener to have separate methods for min, max, warning and critical so
they get found as "notifying properties".

> For instance, in a monitoring application, things like CPU or disk usage can nicely be
displayed as a circular gauge, showing a single (the "current") value.  This paradigm is
currently being used in such products as Apache Ambari (where it is called a "Gauge" widget).
