ChanMonitor is a lib for watch golang channel's load

to know more information see the example

we also provide the http server to get the result

use/debug/chan/all/json to get all watched channels with json format

[{"len":7,"cap":10,"percent":70,"name":"example-1","isOverflow":true},{"len":0,"cap":10,"percent":0,"name":"example-2","isOverflow":false}]

use /debug/chan/overflow/json to get overflow channels with json format

[{"len":7,"cap":10,"percent":70,"name":"example-1","isOverflow":true}]

use /debug/chan/overflow/string to get overflow channels with string format

example-1 overflowd channel len 7 cap 10 len/cap is over 70

1. import the lib in go.mod

require github.com/z2665/chanmonitor v0.1.0

2. import the pkg and add channels to monitor

import "github.com/z2665/chanmonitor/pkg/chanmonitor"
mon := chanmonitor.NewChanMonitor(50)
c := make(chan int, 10)
mon.AddChan("example-1", c)

3. you can use GetSnapshot or GetOverFlowSnapshot get the channels array

tmp:=mon.GetSnapshot()
tmp=mon.GetOverFlowSnapshot()

4. do your own business

5. if you want to set the monitor's interval time,use the NewChanMonitorWithInterval to create the monitor
