title: Metrics filter in Graphite - ignore hierarchy (dots)
body: <p>Is there any way to filter metrics in Graphite while ignoring the hierarchy?</p>
  
  <p>For example:
  Say I have the following metrics:</p>
  
  <pre><code>stats_count.A.B.TestMetric 
  stats_count.A.TestMetric
  stats.A.B.TestMetric
  stats.A.B.TestMetric
  </code></pre>
  
  <p>How can I sum TestMetric under <strong>stats_count only</strong>?</p>
  
  <p>I tried the followings with no success:</p>
  
  <pre><code>stats_counts.*.*.TestMetric - obviously this won't work...
  sumSeriesWithWildcards(stats_counts.[A-Z\.]*[A-Z]*.TestMetric,1)
  sumSeriesWithWildcards(stats_counts.[A-Z]*[.]*[A-Z]*.TestMetric,1)
  </code></pre>
  
  <p>Any ideas? Is it possible at all?</p>
