8.4 Items that can be checked by statistics monitoring

Statistics monitoring allows you to monitor the operational statuses of the J2EE server and batch server.

The following table describes the items that can be monitored as the statistics:

Service	Transaction	Basic information Service name Service type Default value of transaction timeout Statistics Number of active transactions Average transaction time

Note:: The displayed items differ depending on the used functions (whether the function that controls the maximum number of concurrently executing threads is used), option settings, and used resources.
#1: If a resource adapter compliant with the Connector 1.5 specifications is used, Other is output.
#2: If Cosminexus RM is used, these items are output as the statistics of Cosminexus RM. You cannot confirm these items by monitoring the statistics of a Management Server.

Tip

Setting the sampling time of statistical information

Specify sampling time of the statistical information, if the statistics are to be displayed.

When you specify a sampling time, data within the time specified in the sampling time (this is called N seconds) can be displayed as statistical information, by tracing back the time when the window is displayed or updated. This statistical information is N seconds peak and Average value in N seconds. The maximum and minimum values are extracted from the data after the sampling starts.

You can specify a sampling time using the subcommand set of the operation management command (mngsvrutil). For details on the commands, see 7.3 Details of subcommands of the mngsvrutil command in the uCosminexus Application Server Command Reference Guide.
