Sun Java System Application Server Enterprise Edition 8.2 管理指南

PetStore 使用示例

下例说明了如何将 asadmin 工具用于监视目的。

用户要检查将样例 PetStore 应用程序部署到 Application Server 之后在该应用程序中调用某个方法的次数。部署该应用程序的实例名称为 server。结合使用 list 和 get 命令即可访问所需的方法统计信息。

  1. 启动 Application Server 和 asadmin 工具。

  2. 设置一些有用的环境变量，以避免使用每个命令时都输入这些变量：


    asadmin> export AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=admin123
asadmin>export AS_ADMIN_HOST=localhost AS_ADMIN_PORT=4849

  3. 列出实例 server 的可监视组件：


    asadmin> list --user adminuser --monitor server*

    返回结果（输出类似于以下内容）：


    server
server.applications
server.applications.CometEJB
server.applications.ConverterApp
server.applications.petstore
server.http-service
server.resources
server.thread-pools

    可监视组件列表包括 thread-pools、http-service、resources 以及所有已部署（并已启用）的 applications。

  4. 列出 PetStore 应用程序中的可监视子组件（可以用 -m 代替 --monitor）：

    asadmin> list -m server.applications.petstore

    返回：


    server.applications.petstore.signon-ejb_jar
server.applications.petstore.catalog-ejb_jar
server.applications.petstore.uidgen-ejb_jar
server.applications.petstore.customer-ejb_jar
server.applications.petstore.petstore-ejb_jar
server.applications.petstore.petstore\.war
server.applications.petstore.AsyncSenderJAR_jar
server.applications.petstore.cart-ejb_jar

  5. 列出 PetStore 应用程序的 EJB 模块 signon-ejb_jar 中的可监视子组件：


    asadmin> list -m server.applications.petstore.signon-ejb_jar

    返回：


    server.applications.petstore.signon-ejb_jar.SignOnEJB
server.applications.petstore.signon-ejb_jar.UserEJB

  6. 列出 PetStore 应用程序的 EJB 模块 signon-ejb_jar 的实体 Bean UserEJB 中的可监视子组件：


    asadmin> list -m server.applications.petstore.signon-ejb_jar.UserEJB

    返回（出于空间考虑，删除了带点名称）：


    server.applications.petstore.signon-ejb_jar.UserEJB.bean-cache
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods
server.applications.petstore.signon-ejb_jar.UserEJB.bean-pool

  7. 列出 PetStore 应用程序的 EJB 模块 signon-ejb_jar 的实体 Bean UserEJB 所用方法 getUserName 中的可监视子组件：


    asadmin> list -m 
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.getUserName

    返回：


    在 server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.getUserName 没有内容可以列出。要获得以某个字符串开头的有效名称，请使用通配符 "*" 字符。例如，要列出以 "server" 开头的所有名称，请使用 "list server*"。

  8. 该方法没有可监视的子组件。获取方法 getUserName 的所有可监视统计信息。


    asadmin> get -m 
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.getUserName.*

    返回：


    server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-count = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-description = Provides the time in milliseconds 
   spent during the last successful/unsuccessful attempt to execute the 
   operation.
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-lastsampletime = 1079981809259
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-name = ExecutionTime
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-starttime = 1079980593137
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-unit = count
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-count = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-description = Provides the number of times an 
   operation was called, the total time that was spent during the 
   invocation and so on.
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-lastsampletime = 1079980593137
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-maxtime = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-mintime = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-name = ExecutionTime
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-starttime = 1079980593137
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-totaltime = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.methodstatistic-unit =
 server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumerrors-count = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumerrors-description = Provides the total number of errors 
   that occured during invocation or execution of an operation.
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumerrors-lastsampletime = 1079981809273
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumerrors-name = TotalNumErrors
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumerrors-starttime = 1079980593137
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumerrors-unit = count
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumsuccess-count = 0
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumsuccess-description = Provides the total number of 
   successful invocations of the method.
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumsuccess-lastsampletime = 1079981809255
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumsuccess-name = TotalNumSuccess
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumsuccess-starttime = 1079980593137
server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.totalnumsuccess-unit = count

  9. 如果还需要获取执行时间等特定统计信息，请使用如下命令：


    asadmin> get -m server.applications.petstore.signon-ejb_jar.
UserEJB.bean-methods.getUserName.executiontime-count

    返回：


    server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
getUserName.executiontime-count = 1
