I guess it could be related to an "outed" / "old" mongodb driver? But I couldn't find a way to update it locally; i guess it is bundled with Metricbeats? I couldn't find anything related to this issue on the bugs page of the go driver though.. (https://jira.mongodb.org/browse/GODRIVER-1826?jql=project%20%3D%20GODRIVER%20AND%20resolution%20%3D%20Unresolved%20ORDER%20BY%20priority%20DESC%2C%20updated%20DESC)

Pinging @elastic/integrations (Team:Integrations)

[sayden]

Yes, I think that the driver must be updated.

Any news on this? Thanks

any update on this ?

Try to use package from mongo website.
https://www.mongodb.com/try/download/database-tools

It helped for me.

Little bit details of my case.
output from package installed by apt

# mongodump --version
mongodump version: built-without-version-string
git version: built-without-git-spec
Go version: go1.10.1
   os: linux
   arch: amd64
   compiler: gc
OpenSSL version: OpenSSL 1.1.0g  2 Nov 2017

and mongodump fails all the time with the following output

Failed: error connecting to db server: server returned error on SASL authentication step: BSON field 'saslContinue.mechanism' is an unknown field.

After I installed the version from mongo website it run with success
and mongodump version is looks right now.

# mongodump --version
mongodump version: 100.5.2
git version: e2842eb549308c16e070fb2e197d4631cfd085cb
Go version: go1.16.3
   os: linux
   arch: amd64
   compiler: gc

Thanks to: https://stackoverflow.com/questions/68526162/mongodb-connection-error-sasl-with-docker-windows-10
it it made me think.

hi @gad26032, thanks for commeting, but the issue is not the with mongodb toolset (mongodump), but with the metricbeats client which has a mongodb client built in. mongodump and other mongo tools are working on my side

Maybe it is something that has the same cause.
Maybe metcbeats use mongo-tools binaries, and it leads to the same error that I had. Have you tried to reinstall mongo-tools? from the official mongo site?

[sayden]

Beats still uses the old https://github.com/go-mgo/mgo library to connect to MongoDB, which is currently unmaintained.

Beats must switch the library to the official https://github.com/mongodb/mongo-go-driver which AFAIK wasn't available when the module was incorporated into the codebase.

The structure of the events that Beats generates must be maintained, of course or do the minimum possible amount of changes. So, for example, mongodb.dbstats.avg_obj_size.bytes must still be written in the same JSON path after switching libraries.

@rameshelastic FYI

[JohnKnoepfle]

Just curious if we have an update on this issue. Some users are impacted by this.

[cyberjeff-u8t]

We are impacted by this issue since we migrate our database from 4.x to 5.x
Any estimate please ?

[sayden]

We have not received any external contributions to fix the issue and the capacity of the team at Elastic is limited, but it's in the radar of the team.

[EdCSM]

@sayden Any update / ETA? Some users are planning to upgrade MongoDB and this bug is a blocker.

[sayden]

Right now, there's a plan to release this in some minor version ASAP. It's inconvenient, I feel your pain, but the fix is coming 😉

[rajsolanki73]

any update on this ?

[sayden]

There's a PR ongoing already 🙂 #31185

[rajsolanki73]

sorry if i m asking elementary question.

1. when will this be available via metricbeat release or upgrade ?
2. can I try this PR ? if yes then how ?

[cyberjeff-u8t]

Hi,
Same question as @rajsolanki73.
Could someone answer?

[rajsolanki73]

any update on this ?

[cyberjeff-u8t]

any update on this ?

it is now available and working with metricbeat 8.3.1 !

[rajsolanki73]

well for me if i add single server ( i have 3 server cluster with replica set in following template it works.

hosts: ["mymongoserver1:27017"]
username: myuser
password: mypassword

but if add multiple hosts

hosts: ["mymongoserver1:27017",” mymongoserver2:27017”,” mymongoserver3:27017”]
username: myuser
password: mypassword

I get following error.

{"log.level":"error","@timestamp":"2022-07-18T08:21:47.507-0500","log.origin":{"file.name":"module/wrapper.go","file.line":256},"message":"Error fetching data for metricset mongodb.status: could not create mongodb client: could not create mongodb client: a direct connection cannot be made if multiple hosts are specified","service.name":"metricbeat","ecs.version":"1.6.0"}

So then i tried following template

hosts: ["mongodb://myuser:mypass@mymongoserver1:27017", " mongodb://myuser:mypass@mymongoserver2:27017", mongodb://myuser:mypass@mymongoserver3:27017"]

I am facing the same issue with Mongo 6

[ssingh13-rms]

While setting up Metricbeats to monitor MongoDB, I too faced the error too many colons in address.
I followed the standard MongoDB url format (which the mongodb.yml alluded to as well) but it failed to work.

I was able to setup the connection by changing the config like so

  hosts: ["<your_host>:<port>"]
  username: <your_username>
  password: <your_password>

[TomonoriSoejima]

I also faced the same and my environment is below.

• elasticsearch 8.8.1
• metricbeat 8.8.1
• MongoDB 6.0.6 as well as 3.6.23

It looks like metricbeat 8.8.1 is having an error on connecting to even older versions such as above.

[andrei-gutierrez]

any idea when this will be fixed?

[algo7]

any updates?

[Amaimersion]

I had too many colons in address error while connecting to MongoDB 7. Then in Metricbeat config I changed hosts: ["mongodb://localhost:27017"] to hosts: ["localhost:27017"] and it worked.
