404 response code on any endpoint - how to monitor it?

[setevoy2]

Hi, thanks for the tool!

Faced with an issue: adding the service to our monitoring, and found that every endpoint responses with the 404:

$ curl -I http://push.example.com/
HTTP/1.1 404 Not Found
$ curl -I http://push.example.com/healthz
HTTP/1.1 404 Not Found
$ curl -I http://push.example.com/api/config
HTTP/1.1 404 Not Found
$ curl -I http://push.example.com/api/stats/go
HTTP/1.1 404 Not Found

What the correct way to run the checks then?

Hi @setevoy2 ! Can you please show your config?
I ran with default config and these locations returned 200 OK :
http://localhost:8088/version
{ source: "https://github.com/appleboy/gorush", version: "v1.11.2-61-g6bad479" }
http://localhost:8088/
{ text: "Welcome to notification server." }

Which version are you using?

@slimus I reproduced the issue with Postman when using HEAD method, probably this is the issue. Gorush should handle HEAD at least for some endpoints, as this is often used by various monitoring tools. Actually, all what is needed is a line in server.go:

r.HEAD(PushConf.API.HealthURI, heartbeatHandler)

curl default method is GET

$ curl -v http://localhost:8088/healthz
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8088 (#0)
> GET /healthz HTTP/1.1
> Host: localhost:8088
> User-Agent: curl/7.54.0

curl -I for HEAD

$ curl -v -I http://localhost:8088/healthz
