Maintaining History of Data

TIBCO MDM provides a set of MBeans that report performance characteristics of various components.

For example, average, maximum, and minimum time of the JMS message processing are reported. These values change continuously. Therefore, JMX need to maintain the history of data.

Using the JMX Statistics Copier, you can copy JMX statistics into distributed cache. As the cache is common across all TIBCO MDM instances in the cluster, you can use the cache to review information across all nodes and to aggregate the information. You can configure a scheduled job to collect the information from each server. When the job is run, to copy JMX statistics to cache, set the Enable JMX Statistics Copy configuration property to true in Configurator ( ServerName > Miscellaneous for each node). Since this copy is made every second, you can monitor the historical perspective of TIBCO MDM. For example, the cache hit ratio starts with five percent and later goes upto 99 percent, and again starts to drop.
