raw = hs.parsehar('path/to/harfile.json')
data = hs.summarize(raw)
print(hs.serialize(data))Usage: python -m harstatsgraphite [options] <harfile>

Arguments:
  harfile                  path to HAR file (gzipped or plain)

Options:
  -h, --help               show this help message and exit
  -l, --local <fqdn>       local domain name
  -t, --timestamp <sec>    timestamp to use (default: date +%s)
  -f, --format <arg>       plain or pickle (default: plain)
  -p, --prefix <arg>       metric prefix (default: har.summary)

If the '-l --local' option is given, the script will split request
statistics into three groups - requests to the local domain, all
other domains and all requests. Example for 'requests.count':

  har.summary.requests.extern.count 92 1352934738
  har.summary.requests.local.count 28 1352934738
  har.summary.requests.count 120 1352934738'''Installationharstatsgraphite.pyhas no dependencies outside of the Python
