Mongodb Exporter doesn't Show the Metrics Using Docker and Prometheus

Try using: -mongodb.uri mongodb://root:example@mongo:27017

@mostafaghadimi - have you been able to make this work . ! I still have issue not getting full spectrum of mongo metrics through exporter .

[mostafaghadimi]

@pauldintel Yes, I did. Please share the details about how you deploy your applications. In case of using Docker, there might be network related issues.

hi @mostafaghadimi thanks for offering the help . I am using mongo7.0.5, prometheus , nodeexporter , grafana and mongodb exporter in docker container (all inside same network bridge) .
Below is the docker specification :

mongodb-exporter:
hostname: mongodb-exporter
container_name: mongodb-exporter
image: mongoexport:prom
command: ./mongodb_exporter-linux-amd64 -logtostderr -mongodb.uri mongodb://admin1:password@mongo1:27017/mydb -groups.enabled 'asserts,durability,background_flusshing,connections,extra_info,global_lock,index_counters,network,op_counters,op_counters_repl,memory,locks,metrics'
restart: always
ports:
- 9001:9001
networks:
mongo_network:

Please note above mongo1 is the container name and mydb is the db name . the exporter linux utility is used in command line.
the issue with the above is I am getting Authentication failed error : the prometheus portal shows mongo exporter is up and running on 9001 port and no issue . But just shows couple of http# metrics and nothing on mongo metrics shown . So my gut feeling is this is because mongo authentication failure.

Generally at this moment my thought is those user/password needs to be preexisting on the database. Once I create them in database with admin roles I started getting Panic error plus mongo exporter shows down in prometheus ..

So at this moment it is being very strange ! I want to use Grafana dashboard comes pre-shipped with mongo metrics that works on exporter and stuck on implementing that solution.

@pauldintel you're welcome. I think you can create user with environment variables and would you please also share your mongodb service in docker-compose file details?

@pauldintel take a look if this is relevant: #110

I had the same message: panic: runtime error: invalid memory address or nil pointer dereference

I patched according to this comment and it worked.
