Example 5 with Tracer

use of io.opentracing.Tracer in project ballerina by ballerina-lang.

the class TracersStore method getTracers.

/**
 * Return trace implementations for a specific service
 *
 * @param serviceName name of service of whose trace implementations are needed
 * @return trace implementations i.e: zipkin, jaeger
 */
Map<String, Tracer> getTracers(String serviceName) {

                tracerMap.put(tracerGenerator.name, tracer);
            } catch (Throwable ignored) {
            // Tracers will get added only of there's no errors.
            // If tracers contains errors, tracer will be ignored.
            }
        }
        tracerStore.put(serviceName, tracerMap);
        return tracerMap;
