Remotely enabling windows azure diagnostics

I frequently need to Enable and configure collecting performance counters remotely in my windows azure deployment,  There are a few tasks you are trying to accomplish

1- Get all roles you have for your deployment

2- Get the Diagnostics manager associated with each instance of each role

3- Set your Windows Azure Diagnostics Settings. 

I created the following helper class to make it easier for me, hope you find it useful:)

    1:          #region Default Counters

    2:          static string[] defaultCounterNames = new string[] 

    3:          {

    4:              @"\Memory\Available Mbytes", 

    5:              @"\Processor(_Total)\% Processor Time", 

    6:              @"\Processor(*)\% Processor Time",

    7:              @"\Process(*)\Working Set",

    8:              @"\Process(*)\Private Bytes",

    9:              @"\Process(*)\Working Set Peak",

   10:              @"\Process(*)\Virtual Bytes",

   11:              @"\Process(*)\Virtual Bytes Peak"

   12:          };

   13:          #endregion

   14:   

   15:          public static void SetState(string connectionString, string deploymentId , int sampleRateInSeconds, int transferPeriodInSeconds, string[] counterNames = null)

   16:          {

   17:              if (counterNames == null || counterNames.Length == 0)

   18:              {

   19:                  counterNames = defaultCounterNames;

   20:              }

   21:              

   22:              CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(connectionString);

   23:              

   24:              //TODO: Need to remove this if HTTPS is enabled - this allows connecting though http, otherwise the connection will fail.

   25:              DeploymentDiagnosticManager.AllowInsecureRemoteConnections = true;

   26:              

   27:              //Get the diagnostis manager associated with this blob storage.

   28:              DeploymentDiagnosticManager deploymentDiagnosticsManager = new DeploymentDiagnosticManager(cloudStorageAccount, deploymentId);

   29:              

   30:              //Get the role instance diagnostics manager for all instance of the a role

   31:              var roles = deploymentDiagnosticsManager.GetRoleNames();

   32:              foreach (string item in roles)

   33:              {

   34:                  //Get the Role instance Diagnostics manager for each instance. and use it to enable data collection

   35:                  var roleInstanceManagers = deploymentDiagnosticsManager.GetRoleInstanceDiagnosticManagersForRole(item);

   36:                  RoleInstanceDiagnosticManager.AllowInsecureRemoteConnections = true;

   37:                  Console.Out.WriteLine("Getting Diagnostics Managers for Azure Role '{0}'", item);

   38:   

   39:                  //Set the new diagnostic monitor configuration for each instance of the role 

   40:                  foreach (var ridmN in roleInstanceManagers)

   41:                  {

   42:                      Console.Out.WriteLine("\tEnabling counters on instance {0} of role {1}", ridmN.RoleInstanceId, ridmN.RoleName);

   43:   

   44:                      EnableCounters(sampleRateInSeconds, transferPeriodInSeconds, counterNames, ridmN);

   45:                   }

   46:              }

   47:          }

  This is the code that enables the counters for each role instance:

    1:  private static void EnableCounters(int sampleRateInSeconds, int transferPeriodInSeconds, string[] counterNames, RoleInstanceDiagnosticManager ridmN)

    2:          {

    3:              DiagnosticMonitorConfiguration dmc = ridmN.GetCurrentConfiguration();// Depending on what you are trying to fo this can be DiagnosticMonitor.GetDefaultInitialConfiguration();

    4:                     

    5:              counterNames.ToList<String>().ForEach(counterName =>

    6:              {

    7:                  string counterNameTrimmed = counterName.Trim();

    8:                  if (!string.IsNullOrEmpty(counterNameTrimmed))

    9:                  {

   10:                      PerformanceCounterConfiguration pcc = new PerformanceCounterConfiguration();

   11:                      pcc.CounterSpecifier = counterNameTrimmed;

   12:                      pcc.SampleRate = TimeSpan.FromSeconds(sampleRateInSeconds);

   13:                      dmc.PerformanceCounters.DataSources.Add(pcc);

   14:                      Console.Out.WriteLine("\t\tCounter {0} Sample Rate {1} seconds", counterName, sampleRateInSeconds);

   15:                  }

   16:              });

   17:              

   18:              dmc.PerformanceCounters.ScheduledTransferPeriod = TimeSpan.FromSeconds(transferPeriodInSeconds);

   19:              ridmN.SetCurrentConfiguration(dmc);

   20:          }
