Add TrackAvailability method

[DCampodonico]

It would be nice to have the TrackAvailability method in Java. Currently it's only available in .NET.

[trask]

Can you let us know what your use case is for TrackAvailability?

[DCampodonico]

TrackAvailability is needed for cases when you have to write Custom Track Availability Tests.
I have a microservice architecture using gRPC and I want to log availability metrics for this services.

I've made a AvailabilityTelemetry class that apparently it's working.

Please note that I spent only some time on it and may need some care.

import com.microsoft.applicationinsights.internal.schemav2.AvailabilityData;
import com.microsoft.applicationinsights.internal.util.LocalStringsUtils;
import com.microsoft.applicationinsights.internal.util.Sanitizer;
import com.microsoft.applicationinsights.telemetry.BaseSampleSourceTelemetry;

public final class AvailabilityTelemetry extends BaseSampleSourceTelemetry<AvailabilityData> {
  private Double samplingPercentage;
  private final AvailabilityData data;

  /**
   * Envelope Name for this telemetry.
   */
  public static final String ENVELOPE_NAME = "Availability";


  /**
   * Base Type for this telemetry.
   */
  public static final String BASE_TYPE = "AvailabilityData";


  /**
   * Initializes a new instance of the HttpAvailabilityTelemetry class.
   */
  public AvailabilityTelemetry() {
    this.data = new AvailabilityData();
    initialize(this.data.getProperties());
    setId(LocalStringsUtils.generateRandomIntegerId());

    // Setting mandatory fields.
    setTimestamp(new Date());
    setSuccess(true);
  }

  /**

   * time stamp, duration, HTTP response code and success property values.

  public AvailabilityTelemetry(String name, long duration, String runLocation, String message,
      boolean success, ConcurrentMap<String, Double> measurements,
      ConcurrentMap<String, String> properties) {

    this.data = new AvailabilityData();
    
    this.data.setProperties(properties);
    this.data.setMeasurements(measurements);

    initialize(this.data.getProperties());

    setId(LocalStringsUtils.generateRandomIntegerId());

    setTimestamp(new Date());

    setName(name);
    setRunLocation(runLocation);
    setDuration(new Duration(duration));
    setSuccess(success);

  }

  @Override

    return getData().getVer();
  }

  }

  /**

   * @param timestamp he timestamp as Date.
   */
  @Override
  public void setTimestamp(Date timestamp) {
    if (timestamp == null) {
      timestamp = new Date();
    }

    super.setTimestamp(timestamp);
  }

  @Override
  @Deprecated
  protected void additionalSanitize() {
    data.setName(Sanitizer.sanitizeName(data.getName()));
    data.setId(Sanitizer.sanitizeName(data.getId()));

  @Override
  protected AvailabilityData getData() {

  @Override
  public String getEnvelopName() {
    return ENVELOPE_NAME;
  }

  @Override

    return BASE_TYPE;
  }
}

How you should use it:

AvailabilityTelemetry availabilityTelemetry =
        new AvailabilityTelemetry("some-api-name", longDurationMs, "West Europe",
            "some message describing this availability check", booleanSuccess, measurements,  props);

telemetryClient.track(availabilityTelemetry);

Hi, any updates on that?
@ejbp Could you confirm this is still working?
I tried to implement it but no luck so far.

The supported trackEvent() is working though.

[Luisrod12]

Any Updates on getting this capability included in Java on its roadmap?

Thanks in advance.

I missed your message. We have it up and running on production, so Yes, I'm still using this workaround.
