Options are available to give you more control over dump agent
behavior.
exec option
The exec option is used by the tool dump agent to specify
an external application to start.
file option
The file option is used by dump agents that write to a
file.
filter option
Some JVM events occur thousands of times during the lifetime
of an application. Dump agents can use filters and ranges to avoid
excessive dumps being produced.
opts option
The Heapdump agent uses this option to specify the type
of file to produce.
Priority option
One event can generate multiple dumps. The agents that
produce each dump run sequentially and their order is determined by
the priority keyword set for each agent.
range option
You can start and stop dump agents on a particular occurrence
of a JVM event by using the range suboption.
request option
Use the request option to ask the JVM to prepare the state
before starting the dump agent.
defaults option
Each dump type has default options. To view the default
options for a particular dump type, use -Xdump:<type>:defaults.
