Azure / Cosmos DB正在计算我未发出的请求（RU）

Question

I'm working on a simple Xamarin app, that needs to connect to and validate login information against a Cosmos DB collection of users.

My app has had two requests, but the activity in Azure portal is showing many more. Also I only did an "insert" into the azure portal for a single document to test the connection and some basic functionality

What is going on here?

I created the database around 11:00 and this was captured 12:15:

Code that is establishing the connection:

public void Start(string ConnectionString = @"mongodb://secrets"){
//ConnectionString = @"mongodb://192.168.0.111:27017"; // Local test mongodb

MongoClientSettings settings = MongoClientSettings.FromUrl(new MongoUrl(ConnectionString));

settings.SslSettings = new SslSettings() { EnabledSslProtocols = SslProtocols.Tls12 };

//var mongoClient = new MongoClient(settings);

CosmosClient = new MongoClient(settings);
CosmosDatabase = CosmosClient.GetDatabase("dbname");
CosmosUsersCollection = CosmosDatabase.GetCollection<BsonDocument>("users");
Ready = true;}

Code for checking login:

public async Task<string> LoginAsync(string name, string password){
if (!Ready) { Start(); }
var builder = Builders<BsonDocument>.Filter;
var filter = builder.Eq("nick", name) & builder.Eq("password", password);

string output;

try
{
    var var1 = await CosmosUsersCollection.Find(filter).FirstAsync();

    Console.WriteLine("LOGIN RESPONSE: " + var1);

    output = var1.ToJson();
}
catch (Exception ex)
{
    Console.WriteLine("LOGIN FAILED: " + ex.Message);
    output = ex.Message;
    throw;
}

return output;}

And the data I'm reading from

{
"_id" : ObjectId(""),
"nick" : "FRANK_1988",
"password" : "password",
"location" : {
    "type" : "Point",
    "coordinates" : [ 
        58.2237183172273, 
        7.98107150169605
    ]
}

To understand the detail of those requests, you can use Azure Monitor . Go to the Azure Portal and look for the Monitor service:

Go to Metrics :

Then find your resource by Subscription, Resource Group and name and select the Mongo Requests metric:

Finally, Apply a splitting over the Command Name:

Now you should be able to see the detail on each command and which commands are generating those requests. Keep in mind that not always Commands = RU consumption, there are some commands that do not yield consumed RUs (you can see the consumed RUs of a command with GetLastRequestStatistics .
