Description

jstatd
is a
server that provides information about local Java
processes to
the

jps and

jstat programs
running on remote hosts.

jstatd uses RMI and requires special security
permissions to run successfully.
To start

jstatd , create the following file and
name it

jstatd.policy :

grant codebase "file:${java.home}../lib/tools.jar {
permission java.security.AllPermission
}

This policy grants all permissions to any class loaded from the
JDK's

tools.jar JAR file. To
launch

jstatd with this policy, use this command
line:

% jstatd -J-Djava.security.policy=jstat.policy

If an existing

rmiregistry server is running,

jstatd uses it. Otherwise, it creates its own
RMI registry.

Options

-n rminame

Binds the

jstatd remote object to the name

rminame in the RMI registry. The default name is
"JStatRemoteHost", which is what

jps and

jstat look for. Use
of this option requires rminame to be used
in remote

jps and

jstat
invocations.

-nr

Tells jstatd that not to start an internal RMI
registry if none are already running.

-p port

Looks for an existing RMI registry on
port, or starts one on that port if no
existing registry is found.
