Graylog connection to mongo

Graylog Central (peer support)
1

why I’m getting this error no matter what I set monogo to binding IP

Closed connection [connectionId{localValue:4}] to localhost:27017 because there was a socket exception raised by this connection.

MongoDB is not available.

Hell @studioman5150
Not sure , but I would guess it maybe a configuration issue. Is there any more information you can give?

3

If I change to the IP address of the server on both mongo and graylog it still say the same thing. What other information

4

Ok,
graylog config would use 127.0.0.1 and mongo config would be the same 127.0.0.1, Unless these services are separated.

5

Yes I tried the 127.0.01 same issue.

6

Sorry @studioman5150 ,Hard to tell how to troubleshoot your issue with the lack of info. All know is this works for me

#Network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1 

mongodb_uri = mongodb://127.0.0.1/graylog
7

yes that is how I set it up. I tried localhost and the IP, Same issue.

Have you seen this?

I will try it and I will let you know tomorrow.

I try that suggestion, still getting the same error, I can connect to mongo using mongosh

11

But Graylog cant, So that would mean something is not configured correctly to allow Graylog to connect to MongoDb

In our situation on Rocky 8 we see the following:

$ netstat -an | grep 27017
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.1:27017         127.0.0.1:36672         ESTABLISHED
tcp        0      0 127.0.0.1:27017         127.0.0.1:36682         ESTABLISHED
tcp        0      0 127.0.0.1:27017         127.0.0.1:36680         ESTABLISHED

Telnet opens a connection to mongo listening port

$ telnet 127.0.0.1 27017
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

graylog server.conf

mongodb_uri = mongodb://localhost/graylog
mongodb_max_connections = 1000
mongodb_threads_allowed_to_block_multiplier = 5

And the mongod.conf is as stated by gsmith
