All rights reserved. This module defines the MIB that provides access to the Java[tm] Virtual Machine monitoring data. This module is derived from the Java[tm] programming language APIs described in the java.lang.management package of Java[tm] 2, Standard Edition, 5.0. See the Java programming language APIs of JSR 163 for 'Monitoring and Management of the Java[TM] Virtual Machine' for more details. Where the Java programming language API uses long, or int, the MIB often uses the corresponding unsigned quantity - which is closer to the object semantics. In those cases, it often happens that the -1 value that might be used by the API to indicate an unknown/unimplemented value cannot be used. Instead the MIB uses the value 0, which stricly speaking cannot be distinguished from a valid value. In many cases however, a running system will have non-zero values, so using 0 instead of -1 to indicate an unknown quantity does not lose any functionality.
