sendEvent

public void sendEvent(String name,
                      long startMillis,
                      long endMillis,

               throws IOException

Description copied from interface: WavefrontEventSender

Sends the given event to Wavefront

Specified by:

sendEvent in interface WavefrontEventSender

Parameters:

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

startMillis - The timestamp in milliseconds when the event was started.

endMillis - The timestamp in milliseconds when the event was ended.

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

tags - The tags associated with this event.

annotations - The annotations (details, type, severity, e.g.) associated with this event

Throws:

IOException - if there was an error sending the event.

sendDistribution

public void sendDistribution(String name,
                             List<Pair<Double,Integer>> centroids,
                             Set<HistogramGranularity> histogramGranularities,
                             Long timestamp,
                             String source,

                      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.

sendLog

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

Description copied from interface: WavefrontLogSender

This method is used for sending log meta-data to wavefront. This metadata will be stored in LOG atom in wavefront.

Specified by:

sendLog in interface WavefrontLogSender

Parameters:
