Re: https://github.com/wikimedia/operations-puppet/blob/production/modules/webperf/files/asset-check.py

This asset-check.py script currently checks a few selected main pages and aggregates the data into Ganglia graphs, as I understand it. A better approach is probably needed here given that this aggregation makes diagnosis of issues more difficult when examining the graphs and attempting to trace what caused a particular spike.

This script also seems to import itertools needlessly and could use minor additional comments (why the reload(sys)?).

Generally, front end performance instrumentation needs some love. This will probably be the subject of future tickets.
