currently its showing no data for mongo, whereas in 1 service where we use postgresql its displaying the data for that without any extra setup steps.

For mongo

Ankit Nayan

03/15/2023, 6:27 AM

so these

Database calls

are generated using traces from client libs used to connect to DB

Ankit Nayan

and these are client latency, the latency reported by Atlas might be different as it only starts timing once Atlas receives the request

I have seen people see mongo metrics in the charts you show

Ankit Nayan

03/15/2023, 6:29 AM

which language and framework do you use? and what is the name of the mongo client package used?

Copy code

this.sdk = new opentelemetry.NodeSDK({
      traceExporter,
      instrumentations: [
        getNodeAutoInstrumentations(),
        new MongoDBInstrumentation({
          enhancedDatabaseReporting: true,
        }),
      ],
      resource: new Resource({
        [SemanticResourceAttributes.SERVICE_NAME]: `${config.get<string>(
          'service.name',
        )}:${process.env.NODE_ENV}`,
      }),
    });

here is the updated code where I just added

Copy code

new MongoDBInstrumentation({
          enhancedDatabaseReporting: true,
        })

to instrument mongo data, but still not getting anything on the Signoz Dashboard

added this as well, but still no luck no data on the metrics

Divyanshu Negi

03/15/2023, 10:06 AM

Copy code

return this.messageRepo.withTransaction(async (session) => {
      const conversation = await this.conversationRepo.findByIdOrFail(
        conversationId,
        { session },
      );

in the code we are calling this on the API call, which is a mongoose code to query db

I have little clue after this. @Vishal Sharma did you ever get your hands with mongoose? @Divyanshu Negi check the supported version. Also, might be a good time to join otel slack or open an issue with https://github.com/open-telemetry/opentelemetry-js-contrib

@Divyanshu Negi Please check compatible mongoose version. You don’t need to add

opentelemetry/instrumentation-mongoose

separately if you are using

opentelemetry/auto-instrumentations-node

Divyanshu Negi

03/15/2023, 12:03 PM

Thanks, I just added that as well for testing, mongoose was not working, will try the version issue

Vishal Sharma

03/15/2023, 12:03 PM

Which mongoose version are you using?

Divyanshu Negi

03/15/2023, 12:03 PM

"mongoose": "^5.12.7",

Vishal Sharma

03/15/2023, 12:05 PM

And

Vishal Sharma

03/15/2023, 12:06 PM

And which

opentelemetry/auto-instrumentations-node

version are you using?

Divyanshu Negi

03/15/2023, 12:07 PM
