The facility for monitoring MIB performance information can be used to achieve the following objectives:

• Continuous analysis of the HiRDB operating status
  Because you collect and summarize on a regular basis such operating information as RDAREA usage rate and number of server processes, you can quickly and easily analyze the HiRDB operating status from the monitored HiRDB itself and display operating trends and history as graphs.
  
• Early detection of system problems and creation of documents for investigation of problems
  When performance begins to decline in the monitored HiRDB, such as the global buffer hit rate starts to fall, the HiRDB administrator can be alerted to the incipient problem by means of an e-mail. This enables corrective action to be implemented early. Moreover, because information about the problem can be displayed as a graph, documents for investigating and resolving the problem can be prepared easily and expeditiously.
