folsom_cowboy's Issues

The project appears to be broken with recent cowboy

The error looks like this:

08:41:57.114 [error] Error in process <0.319.0> with exit value: {{badmatch,false},[{cowboy_router,execute,2,[{file,"src/cowboy_router.erl"},{line,171}]},{cowboy_protocol,execute,4,[{file,"src/cowboy_protocol.erl"},{line,500}]}]}
08:41:57.118 [error] Supervisor ranch_conns_sup had child ranch_conns_sup started with {ranch_conns_sup,start_protocol,undefined} at <0.319.0> exit with reason no match of right hand value false in cowboy_router:execute/2 line 171 in context child_terminated

May I also suggest you fixing a version of cowboy in your rebar.config?

Folsom has moved

This repo is forked and likely unmaintained.

I no longer have access the folsom related projects and it seems like I probably won't in the near future. To continue maintaining them I have moved the project to https://github.com/folsom-project Please update your projects.

Can't access metric data via REST interface

Hi,

I'm guessing this could be an incompatibility between folsom and folsom_cowboy, but folsom_cowboy doesn't have any tags, so I'm not sure which version I am supposed to use :)

I am able to create a meter metric called msg_per_sec:

folsom_metrics:new_meter(msg_per_sec)

Then I update it every time I receive a new message:

folsom_metrics:notify({msg_per_sec, 1}),

I can see the stats are being collected okay because get_metric_value works fine:

5> folsom_metrics:get_metric_value(msg_per_sec).  

[{count,2257},
 {one,9.793870473767395},
 {five,7.6517299033567285},
 {fifteen,6.22315210736992},
 {mean,9.818651166080544e-6},
 {acceleration,[{one_to_five,0.007140468568035556},
                {five_to_fifteen,0.0023809629933113476},
                {one_to_fifteen,0.003967464851552751}]}]

If I try to look at the available metrics from a browser with "http://localhost:5565/_metrics" I get:

["msg_per_sec"]

But if I try "http://localhost:5565/_metrics/msg_per_sec" I get a 500 error with this in the Erlang console:

Basically I'm not sure whether it's something I'm doing wrong, a version compatibility issue or something else :)
