"HTTP 405 Method Not Allowed" on only a single end-point

Graylog Central (peer support)

Hello,

I’ve set-up a Graylog cluster and the UI works fine, indexing is fine, but I get a “405 method not allowed” error when I hit the following end-point alone:

http://graylog.test:9000/api/system/metrics/multiple/

The exact error message is:

{“type”:“ApiError”,“message”:“HTTP 405 Method Not Allowed”}

My configuration looks like this:

rest_listen_uri = "http://graylog.test:9000/api/"
rest_transport_uri = "http://graylog.test:9000/api/,
web_listen_uri = “http://graylog.test:9000/”

Other API end-points like “/api/system/metrics/” and “/api/system/inputstates” work fine.

I don’t see any error messages in the server log. What could be going wrong?

EDIT:

I’m using Graylog 2.2

Regards,

KN.

That’s because it doesn’t want GET requests. (Mine does the same thing and my cluster works fine.)

What kind of HTTP request (HTTP method, headers, request body) are you sending to http://graylog.test:9000/api/system/metrics/multiple/?

Shortly after posting my question, I realized that the end-point is probably expecting a POST (I was doing a GET earlier), but when I POST like:

curl -u admin -H 'Content-Type: application/json' -X POST -d '{"metrics":["org.graylog2.buffers.input.usage"]}' http://graylog.test:9000/api/system/metrics/multiple

I’m prompted for a password and when I enter the password, I now get a {"type":"ApiError","message":"HTTP 500 Internal Server Error"}% response.

EDIT: copy fail - it was a 500 response (updated the post)

Thanks,

KN.

Figured it out. I needed a -H 'Accept: application/json' as well in addition. I’m sorry for bothering. I hope somebody else finds it helpful.

As a summary, this curl command is working:

$ curl -u $USER:$PASSWORD \
  -X POST \
  -H 'Accept: application/json' \
  -H 'Content-Type: application/json'
  -d '{"metrics":["org.graylog2.buffers.input.usage"]}' \
  'http://127.0.0.1:9000/api/system/metrics/multiple?pretty=true'
{
  "total" : 1,
  "metrics" : [ {
    "full_name" : "org.graylog2.buffers.input.usage",
    "metric" : {
      "value" : 0
    },
    "name" : "usage",
    "type" : "gauge"
  } ]
}
