Question

Hi,

I'm new to Azure, could anyone help me while I'm trying to build C# application to retrieve the VM Metrics data
Metrics are:

1. CPU utlization
2. RAM Usage
3. Logical disk space used.

Can anyone help me with this.

Hello @Goud Kanthi, Aniketh ,
Thanks for your query !
To retrieve those metrics first you might want to enable the diagnostics for that VM.

Go to VM -> Monitoring -> Diagnostics Settings: (Follow the remaining steps)

You can select the required metrics like below:
Performance counters
Collecting data for these counters:
CPU
Memory
Disk
Network

Once you enable those , it will deploy an extension
Microsoft.Azure.Performance.Diagnostics.AzurePerformanceDiagnostics

As a part of enabling that extension , you will have to choose the storage account where all the required metrics will be stored.
In that particular storage account , it will create corresponding tables with name WADMetricsPT* .

Table data and columns looks like below:

You will have to write a C#.net program using Azure API's to query that storage account tables data.

Sample high level piece of code to connect to azure storage table and retrieve the data:

<add key="StorageConnectionString" value="DefaultEndpointsProtocol=https;
AccountName=[Name of storage account];AccountKey=[Access Key for storage account]">

CloudStorageAccount cloudStorageAccount =
CloudStorageAccount.Parse
(ConfigurationManager.AppSettings["StorageConnectionString"]);
CloudTableClient tableClient = cloudStorageAccount.CreateCloudTableClient();
string tableName = "tablename"
CloudTable cloudTable = tableClient.GetTableReference(tableName);
TableOperation tableOperation = TableOperation.Retrieve(partitionKey, rowKey);
TableResult tableResult = table.Execute(tableOperation);

Please Note: You will have to query the corresponding Metrics which is available in CounterName Column

Kindly let us know if you need additional help on this.
