Class OpenCensusMetricExporterSpi

java.lang.Object

org.apache.ignite.spi.IgniteSpiAdapter

org.apache.ignite.internal.processors.metric.PushMetricsExporterAdapter

org.apache.ignite.spi.metric.opencensus.OpenCensusMetricExporterSpi

All Implemented Interfaces:

IgniteSpi, MetricExporterSpi

public class OpenCensusMetricExporterSpi
extends org.apache.ignite.internal.processors.metric.PushMetricsExporterAdapter

OpenCensus monitoring exporter.

This class will export all Ignite metrics with the OpenCensus API.

Please, note, metrics recorded with the OpenCensus API each PushMetricsExporterAdapter.period milliseconds.
To enable export from OpenCensus to the wild user should configure OpenCensus exporter. Please, see OpenCensus documentation for additional information. Example of exporter configuration:

 
   PrometheusStatsCollector.createAndRegister();

   HTTPServer server = new HTTPServer("localhost", 8888, true);

Method Detail

export

public void export()

Callback to do the export of metrics info. Method will be called into some Ignite managed thread each PushMetricsExporterAdapter.getPeriod() millisecond.

Specified by:

export in class org.apache.ignite.internal.processors.metric.PushMetricsExporterAdapter

spiStart

public void spiStart(@Nullable
                     @Nullable String igniteInstanceName)
              throws IgniteSpiException

This method is called to start SPI. After this method returns successfully kernel assumes that SPI is fully operational.

Specified by:

spiStart in interface IgniteSpi

Overrides:

spiStart in class org.apache.ignite.internal.processors.metric.PushMetricsExporterAdapter

Parameters:

igniteInstanceName - Name of Ignite instance this SPI is being started for (null for default Ignite instance).

Throws:

IgniteSpiException - Throws in case of any error during SPI start.

onContextInitialized0

protected void onContextInitialized0(IgniteSpiContext spiCtx)
                              throws IgniteSpiException

Method to be called in the end of onContextInitialized method.

Overrides:

onContextInitialized0 in class org.apache.ignite.internal.processors.metric.PushMetricsExporterAdapter

Parameters:

spiCtx - SPI context.

Throws:

IgniteSpiException - In case of errors.

setSendInstanceName

public void setSendInstanceName(boolean sendInstanceName)

If true then INSTANCE_NAME_TAG will be added to each exported measure.

Parameters:

sendInstanceName - Flag value.

setSendNodeId

public void setSendNodeId(boolean sendNodeId)

If true then NODE_ID_TAG will be added to each exported measure.

Parameters:

sendNodeId - Flag value.

setSendConsistentId

public void setSendConsistentId(boolean sendConsistentId)

If true then CONSISTENT_ID_TAG will be added to each exported measure.

Parameters:

sendConsistentId - Flag value.
