When working on adding a 'Top XX' widget to a node dashboard, we found that trying to filter it down to the specific node it was on didn't work unless you statically put in what node it was. We were trying to leverage 'NodeID=${NodeID}' so that it would be dynamic across all applicable nodes and display 'Top XX' data that would be applicable to the node. We found that it processed the filter, but would just bypass it. Though if we used a static Node ID, then it would display as expected. Though support told me to put in a feature request for this, I believe defining it more as a 'bug' would be accurate due to the fact that the feature already exists in the widget itself, it just doesn't process it the way it should with the variable.
