Where does the data list? It seems like something we'd want to integrate into the central Portal dashboards once those exist. On 2 November 2015 at 17:59, Erik Bernhardson <ebernhardson(a)wikimedia.org> wrote: -- Oliver Keyes Count Logula Wikimedia Foundation

I forgot to note that grafana has other inputs it can source metrics from, if it's using something other than graphite it will say so in the bottom right-hand corner of the 'edit' page On Mon, Nov 2, 2015 at 3:48 PM, Erik Bernhardson <ebernhardson(a)wikimedia.org > Most likely this data is all in graphite.

This is certainly better, great work! How can we move further? I'm amazed that it still has an average of almost 1.5s, how could we figure out what is taking so long? Is it (random example) due to the average user being on a slow mobile network with high latency? Would be interesting to investigate. One idea from prod would be to use data uri's in css that fallback to normal urls? IIRC most browsers support data uris up to 32kB which should fit all the images we use and potentially save eighteen requests.
