title: Graphite: Help me interpret the whisper-info.py output
body: <p>I have been trying to make sense out of the whisper-info.py output and it seems a little cryptic to me. </p>
  
  <p>Currently this is my setup:</p>
  
  <p><strong>storage-schema.conf</strong></p>
  
  <pre><code>[carbon]
  pattern = ^carbon\.
  retentions = 60:90d
  
  [stats]
  pattern = ^stats.*
  retentions = 30s:6h,1min:30d,10min:360d,30min:720d,1h:1825d,1d:1825d
  
  [everything_else]
  pattern = .*
  retentions = 30s:6h,1min:30d,10min:360d,30min:720d,1h:1825d,1d:1825d
  </code></pre>
  
  <p><strong>storage-aggregation.conf</strong></p>
  
  <pre><code>[min]
  pattern = \.lower$
  xFilesFactor = 0.1
  aggregationMethod = min
  
  [max]
  pattern = \.upper(_\d+)?$
  xFilesFactor = 0.1
  aggregationMethod = max
  
  [sum]
  pattern = \.sum$
  xFilesFactor = 0
  aggregationMethod = sum
  
  [count]
  pattern = \.count$
  xFilesFactor = 0
  aggregationMethod = sum
  
  [count_legacy]
  pattern = ^stats_counts.*
  xFilesFactor = 0
  aggregationMethod = sum
  
  [default_average]
  pattern = .*
  xFilesFactor = 0.3
  aggregationMethod = average
  </code></pre>
  
  <p>I have statsd in front of it, pretty minimal
  <strong>localConfig.js</strong></p>
  
  <pre><code>{
  graphitePort: 2003,
  graphiteHost: "127.0.0.1",
  port: 8125,
  flushInterval: 30000,
  }
  </code></pre>
  
  <p>now I send a packet to stasd to a completely new metric</p>
  
  <pre><code>echo "alex.foo:1|c" | nc -w1 -u 127.0.0.1 8125
  </code></pre>
  
  <p>and this is the output of the whisper-info.py:</p>
  
  <pre><code># whisper-info.py /opt/graphite/storage/whisper/stats/alex/foo.wsp 
  maxRetention: 604800
  xFilesFactor: 0.300000011921
  aggregationMethod: average
  fileSize: 120988
  
  Archive 0
  retention: 604800
  secondsPerPoint: 60
  points: 10080
  size: 120960
  offset: 28
  </code></pre>
  
  <p>Why is there only one archive when I clearly have so much more retentions setup? are my schema rules not correct? what is the meaning of the output? is size the file size? offset?</p>
  
  <p>Thank you for taking the time to answer!</p>
