Configure Performance Manager Infrastructure using scripting

 

You can use scripting to configure a Performance Manager Infrastructure service. Before starting this task, the wsadmin tool must be running. See the Start the wsadmin scripting client article for more information.

 

Overview

Use the following steps to configure the Performance Manager Infrastructure (PMI) service for an appserver:

 

Procedure

1. Identify the appserver and assign it to the s1 variable, for example:

   • Use Jacl:

     set s1 [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
     

   • Use Jython:

     s1 = AdminConfig.getid('Cell:mycell/Node:mynode/Server:server1/') 
     

   where:

   set	Jacl command
   s1	variable name
   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object representing the WebSphere Application Server configuration
   getid	AdminConfig command
   Cell	attribute
   mycell	value of the Cell attribute
   Node	attribute
   mynode	value of the Node attribute
   Server	attribute
   server1	value of the Server attribute

   Example output:

   server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1)
   

2. Identify the PMI service that belongs to the server and assign it to the pmi variable...

   • Use Jacl:

     set pmi [$AdminConfig list PMIService $s1]
     

   • Use Jython:

     pmi = AdminConfig.list('PMIService', s1) print pmi 
     

   where:

   set	Jacl command
   pmi	variable name
   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object representing the WebSphere Application Server configuration
   list	AdminConfig command
   PMIService	AdminConfig object
   s1	evaluates to the ID of the appserver specified in step number 1

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#PMIService_1)
   

3. Modify the attributes...

   • Use Jacl:

     $AdminConfig modify $pmi {{enable true} {statisticSet ALL}}
     

   • Use Jython:

     AdminConfig.modify(pmi, [['enable', 'true'], ['statisticSet','ALL']]
     

   This example enables PMI service and sets the specification levels for all of components in the server. The following are the valid specification levels for the components:

   NONE	No statistics are enabled.
   BASIC	Statistics specified in J2EE 1.4, as well as top statistics like CPU usage and live HTTP sessions are enabled. This set is enabled out-of-the-box and provides basic performance data about runtime and application components.
   EXTENDED	Basic set plus key statistics from various WAS components like WLM and Dynamic caching are enabled. This set provides detailed performance data about various runtime and application components.
   ALL	All statistics are enabled.
   CUSTOM	Enable or disable statistics selectively.

4. Save the configuration changes. See the Saving configuration changes with the wsadmin tool article for more information.

5. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with the wsadmin tool article for more information.
