Ops

 * Image scalers http://ganglia.wikimedia.org/latest/?r=hour&cs=&ce=&s=by+name&c=Image%2520scalers%2520eqiad&tab=m&vn=&hide-hf=false

These servers are responsible for generating thumbnails, which Media Viewer triggers a lot since thumbnails are generated on-the-fly when they don't exist yet.


 * API methods http://gdash.wikimedia.org/dashboards/apimethods/
 * PHP latency http://gdash.wikimedia.org/dashboards/totalphp/

Media Viewer relies on several APIs on the PHP side, some of which are specific to Media Viewer.


 * StreamFile http://gdash.wikimedia.org/dashboards/filebackend/

Thumbnails, after being generated, are streamed using the StreamFile method.


 * Media Storage http://ganglia.wikimedia.org/latest/?r=hour&cs=&ce=&tab=v&vn=Media+storage&hide-hf=false

Presumably where images are stored. Not sure if originals or thumbs, we should clarify that with ops.
