Example 1 with OperatorMetrics

use of com.ibm.streams.operator.metrics.OperatorMetrics in project streamsx.topology by IBMStreams.

the class Resetter method createConditionMetrics.

private void createConditionMetrics() {
    final OperatorMetrics metrics = getOperatorContext().getMetrics();
    final String name = getConditionName();
    valid = metrics.createCustomMetric(metricName("valid", name), "Condition: " + name + " is valid", Metric.Kind.GAUGE);

    fail = metrics.createCustomMetric(metricName("fail", name), "Condition: " + name + " failed", Metric.Kind.GAUGE);
}

Example 2 with OperatorMetrics

use of com.ibm.streams.operator.metrics.OperatorMetrics in project streamsx.kafka by IBMStreams.

the class AbstractKafkaClient method tryCreateCustomMetric.

/**
 * Tests existence of a custom metric and creates the metric if it does not yet exist.
 * @param name  the name of the metric
 * @param descr the description
 * @param kind  the kind of the metric
 * @return the Metric object.

Example 3 with OperatorMetrics

use of com.ibm.streams.operator.metrics.OperatorMetrics in project streamsx.kafka by IBMStreams.

the class AbstractCustomMetricReporter method metricRemoval.

/**
 * This is called whenever a metric is removed.
 * It sets the value of the corresponding operator metric,
 * if there is one, to {@value #METRIC_NOT_APPLICABLE} as custom metrics cannot be deleted from operators.

 * @param metric The metric that is removed from Kafka
