Class filters for VM Container profiling

Use

Class filters are used to restrict VM Container profiling to specific Java classes or applications. A class filter must be created using the following syntax:

<filter>     ->     <atom>

<filter>     ->     <filter> & <filter>

<filter>     ->    <filter> | <filter>

<filter>        ->    ! <filter>

<filter>        ->    ( <filter> )

<atom>    ->    <pattern>

<atom>    ->    is <pattern>

<atom>    ->    extends <name>

<atom>    ->    implements <name>

<atom>    ->    instanceof <name>

<atom>    ->    instanceof <name>[]

<pattern>    ->    <name>

<pattern>    ->    <name>[]

<pattern>    ->    <name>*

<pattern>    ->    <name>*[]

<pattern>    ->    <name>**

<pattern>    ->    <name>**[]

<pattern>    ->    <primitive>

<pattern>    ->    <primitive>[]

<primitive>    ->    boolean | Z

<primitive>    ->    byte | B

<primitve>    ->    short | S

<primitve>    ->    char | C

<primitive>    ->    int | I

<primitive>    ->    long | J

<primitive>    ->    float | F

<primitive>    ->    double | D

Using a name suffix

By using a name suffix the specified name is interpreted as a pattern and compared to the actual Java packet or class name. The following suffixes are possible:

  • *    Extension up to the end of the name but only to a maximum of the next point
  • **    Extension up to the end of the name without any restrictions
  • []    Array class

The name suffix "*" means that the specified name is a prefix for all package or class names up to the next point "."

Example: com.sap.vmc.rem*   

  • Contains package com.sap.vmc.remserver including all classes
  • Does not contain packages com.sap.vmc.remserver.builtin and com.sap.vmc.remserver.repository

       

The name suffix '**' means that the specified name is the standard prefix for all package and class names.

Example: com.sap.vmc.rem**

  • Contains all packages that begin with "com.sap.vmc.rem":
    • com.sap.vmc.remserver including all classes
    • com.sap.vmc.remserver.builtin including all classes
    • com.sap.vmc.remserver.repository including all classes
  • Contains arrays that were not created from these classes (for instance, com.sap.vmc.remserver.HandlerWrapper[] )

The name suffix "[]" means that the name describes a class and the filter contains all the arrays created from this.
