Interface JmsConnectorMBean

  • public interface JmsConnectorMBean
    Multiple JmsConnectorMBean instances are allowed in the system. Each JmsConnectorMBean instance pertains to one JMS Connector instance. Each JMS Connector instance is bound to one JmsConnectorMBean instance. Each JmsConnectorMBean instance is created at startup by the Server and lasts until the shutdown of the Server. Remote JMX clients should not deregister JmsConnectorMBean instances.

    JmsConnectorMBean name pattern:
    "com.lightstreamer:type=JmsConnector,JmsConnectorName=JMS.<JmsConnectorName>"

      • getConsumers

        java.lang.Integer getConsumers()

        java.lang.Integer getMaxPooledBrokerConnections()
        Returns:
        The maximum number of currently active pooled connections to the JMS broker in this JMS Connector, reached in the life of the Server.

      • startCollectingAcknowledgeLatencyInfo

        java.lang.Boolean startCollectingAcknowledgeLatencyInfo​(long latencyReportInterval)
        Starts collecting statistical information on the delay that occurs between sending a message downstream and receiving its acknowledgement (acknowledge latency). At each specified interval a report is generated. Each report contains a simple chart with latency distribution up to 90th percentile. Acknowledge latency may also be configured for logging in the JMS Connector configuration.
        Parameters:
        latencyReportInterval - The interval between successive report generation. Expressed in milliseconds.
        Returns:
        True if operation succeeded. False if operation failed.

      • stopCollectingAcknowledgeLatencyInfo

        java.lang.Boolean stopCollectingAcknowledgeLatencyInfo()
        Stops collecting statistical information on the delay that occurs between sending a message downstream and receiving its acknowledgement (acknowledge latency). If acknowledge latency logging is configured in the JMS Connector configuration, this operation stop logging too.
        Returns:
        True if operation succeeded. False if operation failed.

      • dumpLastAcknowledgeLatencyReport

        java.lang.String dumpLastAcknowledgeLatencyReport()
        Dumps the latest generated report on acknowledge latency. See also jmsAcknowledgeLatencyStartCollectingInfo and jmsAcknowledgeLatencyStopCollectingInfo.
        Returns:
        The latest generated report.
