How to know the number of tcp connections created based on the configuration options ?

[kkattamudi-ms]

Even we restricted the cosmos db client objects to be 6 and with maximum TCP Connections to be created as 100 . We are seeing huge number of TCP Connections are getting created due to which the performace of our worker is getting degraded .
Please find the code sample we are using :
CosmosDB Client Options :
"MaxRequestsPerTcpConnection": 10,
"MaxTcpConnectionsPerEndpoint": 100

        this.cosmosClient = await cosmosClientBuilder
            .WithConnectionModeDirect(maxRequestsPerTcpConnection: this.options.ConnectionPolicy.MaxRequestsPerTcpConnection, maxTcpConnectionsPerEndpoint: this.options.ConnectionPolicy.MaxTcpConnectionsPerEndpoint)
            .WithRequestTimeout(this.options.ConnectionPolicy.RequestTimeout)
            .WithApplicationRegion(this.options.ConnectionPolicy.CurrentLocation)
            .WithThrottlingRetryOptions(TimeSpan.FromSeconds(this.options.ConnectionPolicy.RetryOptions.MaxRetryWaitTimeInSeconds), this.options.ConnectionPolicy.RetryOptions.MaxRetryAttemptsOnThrottledRequests)
            .BuildAndInitializeAsync(containersToInitialize)
            .ConfigureAwait(false);

When we are tracing the logs of cosmos db requests we are seeing this :
"numberOfOpenTcpConnection": 10276
"NumberOfClientsCreated": 6,
"NumberOfActiveClients": 6,

When using Direct Mode, your machine will connect to all 4 replicas of each physical partition, from each of the clients. The option of MaxTcpConnectionsPerEndpoint is for each backend node.

What happens if you try the recommended settings in the above?

Currently we are running with 300+ machines but we are not able to scale to the desired throughput.

The incoming data is getting backlogged and we are seeing timeout exceptions sometimes from cosmosdb in our logs .

But have you applied the recommended settings?

Do you mean from the shared links ?(https://learn.microsoft.com/azure/cosmos-db/nosql/tune-connection-configurations-net-sdk-v3) can you please share the specific settings if they are different?
