The error events are getting submitted as info event for event having \n in the event body.

Code :-

package main

import(
 "github.com/ooyala/go-dogstatsd"
 "log"
 "fmt"
)

func main() {
    c,err := dogstatsd.New("127.0.0.1:8125")
    defer c.Close()
    if err != nil {
        log.Fatal(err)
    }
    c.Namespace = "test"
    err = c.Error("Testing", "Testing Hello\n World", nil)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println("Error Event Submitted")
}

The above event in datadog is showing up as info event with Title - Testing and body Testing Hello.

The udp message submitted by go-dogstatsd looks like below:-

_e{13,1681}:Testing |Testing Hello
World|t:error|s:test

It seems the entire message after Testing Hello is getting truncated in datadog. So the event type (t:error) is also getting truncated & by default if the event type is missing in any of the events then it seems datadog treats it as info event.

To check how the event datagram submitted by go-dogstatsd look like I started a tcpdump on port 8125 with the below command and then executed the above code:-

sudo tcpdump -i lo udp port 8125 -vv -X

The outputted datagram look like the below:-

_e{7,20}:Testing|Testing.Hello..World|t:error|s:test

which is not what we want.

If the "Testing Hello\n World" is submitted directly using the below command:-

echo -n "_e{4,21}:Test|Testing Hello\n World" | nc -4u -w1 localhost 8125

Then the outputted datagram look like the below:-

_e{7,20}:Testing|Testing.Hello\n.World|t:error|s:test
