Description
I have a custom jasper report template that uses the Measurements API:
<queryString language="measurement"> <![CDATA[<query-request step="300000" start="$P{startDateTime}" end="$P{endDateTime}" maxrows="5000"> <source aggregation="AVERAGE" label="ifInErrors" attribute="ifInErrors" transient="false" resourceId="$P{nodeResourceDescriptor}.interfaceSnmp[$P{interface}]"/> <source aggregation="AVERAGE" label="ifOutErrors" attribute="ifOutErrors" transient="false" resourceId="$P{nodeResourceDescriptor}.interfaceSnmp[$P{interface}]"/> <source aggregation="AVERAGE" label="ifOutDiscards" attribute="ifOutDiscards" transient="false" resourceId="$P{nodeResourceDescriptor}.interfaceSnmp[$P{interface}]"/> <source aggregation="AVERAGE" label="ifInDiscards" attribute="ifInDiscards" transient="false" resourceId="$P{nodeResourceDescriptor}.interfaceSnmp[$P{interface}]"/> <source aggregation="AVERAGE" label="InPauseFrame" attribute="dot3HCInPauseFrame" transient="false" resourceId="$P{nodeResourceDescriptor}.interfaceSnmp[$P{interface}]"/> </query-request>]]> </queryString>
For all the nodes involved, some of the interface have all the attributes, but some of them don't (specially dot3HCInPauseFrame). When they don't have the attributes, an exception is thrown and the report is generated but all the values associated with metric fields are always going to be null, even those that are supposed to have data:

A missing resource or attribute should not break the filling process of a report. In fact, with the old jrobin/rrdtool query language, a missing entity is silently ignored (i.e. no data, NaN or whatever Jasper expects for "not a number"), which is the expected behavior.
