Class WavefrontMultiClient<T extends WavefrontSender & Runnable>

java.lang.Object

com.wavefront.sdk.common.clients.WavefrontMultiClient<T>

All Implemented Interfaces:

BufferFlusher, WavefrontSender, WavefrontHistogramSender, WavefrontMetricSender, WavefrontTracingSpanSender, Closeable, AutoCloseable, Runnable

public class WavefrontMultiClient<T extends WavefrontSender & Runnable>
extends Object
implements WavefrontSender, Runnable

WavefrontMultiClient supports multicasting metrics/distributions/spans onto multiple endpoints for either Proxy or Direct Ingestion. User should probably attempt to reconnect when exceptions are thrown from any methods.

Method Detail

getClient

public T getClient(String clientId)

Provide direct access to a specific client by id.

Parameters:

clientId - the unique client ID generated when a Proxy or DirectIngestion Client is instantiated.

Returns:

The client found or null if no client is found matching the supplied clientId.

flush

public void flush()
           throws IOException

Description copied from interface: BufferFlusher

Flushes buffer, if applicable

Specified by:

flush in interface BufferFlusher

Throws:

IOException

getFailureCount

public int getFailureCount()

Description copied from interface: BufferFlusher

Returns the number of failed writes to the server.

Specified by:

getFailureCount in interface BufferFlusher

Returns:

the number of failed writes to the server

getFailureCountPerSender

public Map<String,Integer> getFailureCountPerSender()

Obtain the failure counts per endpoint.

Returns:

a map of clientId's to failures per endpoint.

sendMetric

public void sendMetric(String name,
                       double value,
                       @Nullable
                       Long timestamp,
                       @Nullable
                       String source,
                       @Nullable
                       Map<String,String> tags)
                throws IOException

Description copied from interface: WavefrontMetricSender

Sends the given metric to Wavefront

Specified by:

sendMetric in interface WavefrontMetricSender

Parameters:

name - The name of the metric. Spaces are replaced with '-' (dashes) and quotes will be automatically escaped.

value - The value to be sent.

timestamp - The timestamp in milliseconds since the epoch to be sent. If null then the timestamp is assigned by Wavefront when data is received.

source - The source (or host) that's sending the metric. If null then assigned by Wavefront.

tags - The tags associated with this metric.

Throws:

IOException - if there was an error sending the metric.

sendFormattedMetric

public void sendFormattedMetric(String point)
                         throws IOException

Description copied from interface: WavefrontMetricSender

Similar to WavefrontMetricSender.sendMetric(String, double, Long, String, Map), only the point argument is expected to already be in Wavefront Data Format

Specified by:

sendFormattedMetric in interface WavefrontMetricSender

Parameters:

point - a single metric, encoded in Wavefront Data Format

Throws:

IOException - if there was an error sending the metric.

sendDistribution

public void sendDistribution(String name,
                             List<Pair<Double,Integer>> centroids,
                             Set<HistogramGranularity> histogramGranularities,
                             @Nullable
                             Long timestamp,
                             @Nullable
                             String source,
                             @Nullable
                             Map<String,String> tags)
                      throws IOException

Specified by:

sendDistribution in interface WavefrontHistogramSender

Parameters:

name - The name of the histogram distribution. Spaces are replaced with '-' (dashes) and quotes will be automatically escaped.

centroids - The distribution of histogram points to be sent. Each centroid is a 2-dimensional Pair where the first dimension is the mean value (Double) of the centroid and second dimension is the count of points in that centroid.

histogramGranularities - The set of intervals (minute, hour, and/or day) by which histogram data should be aggregated.

timestamp - The timestamp in milliseconds since the epoch to be sent. If null then the timestamp is assigned by Wavefront when data is received.

source - The source (or host) that's sending the histogram. If null, then assigned by Wavefront.

tags - The tags associated with this histogram.

Throws:

IOException - If there was an error sending the histogram.

sendSpan

public void sendSpan(String name,
                     long startMillis,
