goroutine count is wrong

add chart for monitoring CPU usage

add chart for monitoring CPU usage, thanks.

Migrate to a fully open-source javascript charting library.

Highcharts is a great product, but the licensing terms aren't. Please switch to a library like flot that has less restrictive license terms.

calls to log.Fatal() make me nervous

Errors happen all the time at scale. I'm hesitant to deploy a service to production built with this knowing that log.Fatal() might be called and my application would exit. I think log.Println/return pair would be sufficient in most of the cases.

Alternatively have it configurable with a package-level variable.

it would be better to bind plotly in the offline cases

since you've download static js script. I think it would be better to add plotly to bindata.

no charts, errors in console

when accessing charts i see only one empty chart and a bunch of errors in console:

Why does the heap keep growing

Why does the heap keep growing

Memory is not leaking and it keeps growing

when use this
found default log Prefix not exists, like

log.Println("xxxx")

2017/09/04 13:25:10 xxxx

http.ServeMux

Hi, remove init() and create func that will returned http.ServeMux server with all necessary handlers to allow developers to choose addr and port.
And hide Assert funcs
(if you have not many time let me do this)

add expvars support

That will be great.

Or how to add expvar to this?
Can you read expvar automatically via enumerate exporing variables or smth like this?
