pmm2 for sharded mongodb

[arash_moosavi]

Hi,

I have installed PMM 2.10.1 and Configured cluster of MongoDB 4.4.0 with this structure:

Server1:

mongo-router-01:27017

mongo-config-01:27021

mongo-shard-01-node-a:27018

mongo-shard-01-node-b:27019

mongo-shard-01-node-c:27020

Server2:

mongo-router-02:27017

mongo-config-02:27021

mongo-shard-02-node-a:27018

mongo-shard-02-node-b:27019

mongo-shard-02-node-c:27020

Server3:

mongo-router-03:27017

mongo-config-03:27021

mongo-shard-03-node-a:27018

mongo-shard-03-node-b:27019

mongo-shard-03-node-c:27020

I just added mongo-router-01:27017 to pmm-admin with following command and it is OK:

sudo pmm-admin add mongodb --cluster someMongoCluster --username=mongodb_exporter --password=SomeStrongPassword

But when I try to add mongo-shard-01-node-a with the following command:

sudo pmm-admin add mongodb --cluster someMongoCluster --replication-set=mongo-shard-01 --username=mongodb_exporter --password=SomeStrongPassword mongo-shard-01-node-a mongo-shard-01-node-a:27018

Following Error has occurred:

Connection check failed: connection() : auth error: sasl conversation error: unable to authenticate using mechanism “SCRAM-SHA-1”: (AuthenticationFailed) Authentication failed…

l am sure username and password are correct.

What is the problem?

Why Percona has not provide an straightforward get start about fully implementation of PMM 2 for Secured Clustered MongoDB?

Hi Arash,

Could you try the same command but setting the password between single quotes?

… --password=‘SomeStrongPassword’ …

I tried it, it doesn’t worked.

I don’t have space and any special character in my password. [a-zA-Z0-9]

Are you able connect to the mongod instance by using user mongodb_exporter?

mongo -u mongodb_exporter -p ‘s3cR#tpa$$worD’ --port=27018 --host=mongo-shard-01-node-a
