Class AtlasMetricObserver

java.lang.Object

com.netflix.servo.publish.atlas.AtlasMetricObserver

All Implemented Interfaces:

com.netflix.servo.publish.MetricObserver

public class AtlasMetricObserver
extends java.lang.Object
implements com.netflix.servo.publish.MetricObserver

Observer that forwards metrics to atlas. In addition to being MetricObserver, it also supports a push model that sends metrics as soon as possible (asynchronously).

Constructor Detail

AtlasMetricObserver

public AtlasMetricObserver(ServoAtlasConfig config,
                           com.netflix.servo.tag.TagList commonTags)

Create an observer that can send metrics to atlas with a given config and list of common tags. This method will use the default poller index of 0.

AtlasMetricObserver

public AtlasMetricObserver(ServoAtlasConfig config,
                           com.netflix.servo.tag.TagList commonTags,
                           int pollerIdx)

Create an observer that can send metrics to atlas with a given config, list of common tags, and poller index.

AtlasMetricObserver

public AtlasMetricObserver(ServoAtlasConfig config,
                           com.netflix.servo.tag.TagList commonTags,
                           int pollerIdx,
                           HttpHelper httpHelper)

Create an atlas observer. For internal use of servo only.

Method Detail

shouldDumpPayload

protected boolean shouldDumpPayload()

getPayloadDirectory

protected java.lang.String getPayloadDirectory()

stop

public void stop()

Stop attempting to send metrics to atlas. Cleans up the thread that is created by this observer.

newErrCounter

protected static com.netflix.servo.monitor.Counter newErrCounter(java.lang.String name,
                                                                 java.lang.String err)

asGauge

protected static com.netflix.servo.Metric asGauge(com.netflix.servo.Metric m)

asCounter

protected static com.netflix.servo.Metric asCounter(com.netflix.servo.Metric m)

isCounter

protected static boolean isCounter(com.netflix.servo.Metric m)

isGauge

protected static boolean isGauge(com.netflix.servo.Metric m)

isRate

protected static boolean isRate(com.netflix.servo.Metric m)

identifyDsTypes

protected static java.util.List<com.netflix.servo.Metric> identifyDsTypes(java.util.List<com.netflix.servo.Metric> metrics)

getName

public java.lang.String getName()

Specified by:

getName in interface com.netflix.servo.publish.MetricObserver

push

public void push(java.util.List<com.netflix.servo.Metric> rawMetrics)

Immediately send metrics to the backend.

Parameters:

rawMetrics - Metrics to be sent. Names and tags will be sanitized.

sendNow

protected void dumpPayload(java.io.File out,
                           JsonPayload payload)
                    throws java.io.IOException

Throws:

java.io.IOException

getSenderObservable

protected rx.Observable<java.lang.Integer> getSenderObservable(com.netflix.servo.tag.TagList tags,
                                                               com.netflix.servo.Metric[] batch)

getCommonTags

protected com.netflix.servo.tag.TagList getCommonTags()

Get the list of common tags that will be added to all metrics sent by this Observer.

withBookkeeping

protected rx.functions.Func1<iep.io.reactivex.netty.protocol.http.client.HttpClientResponse<io.netty.buffer.ByteBuf>,java.lang.Integer> withBookkeeping(int batchSize)

Utility function to map an Observable<ByteBuf> to an Observable<Integer> while also updating our counters for metrics sent and errors.
