Example 1 with Kind

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

the class FunctionOperatorContext method createCustomMetric.

@Override

    name = requireNonNull(name);
    description = requireNonNull(description);
    LongSupplier supplier = requireNonNull(value);
    Kind ekind = Metric.Kind.valueOf(kind.toUpperCase(Locale.US));
    Metric cm;
    try {
        cm = context.getMetrics().createCustomMetric(name, description, ekind);
    } catch (IllegalArgumentException e) {
        // the new value supplier.
        if (metrics != null) {
            synchronized (metrics) {
                for (MetricSetter ms : metrics) if (ms.metric.getName().equals(name))
                    throw e;
            }
        }
        cm = context.getMetrics().getCustomMetric(name);
