enable-monitoring

Enables monitoring for the server or for specific monitorable modules

Synopsis

asadmin [asadmin-options] enable-monitoring [--help]

[--mbean={false|true}]
[--dtrace={true|false}]
[--modules modules[=level][:module[=level]]*
[--pid pid]
[--options options]]

Description

The enable-monitoring subcommand is used to turn on monitoring for Eclipse GlassFish or for particular modules during runtime. Changes are dynamic, that is, server restart is not required.

By default, the monitoring service is enabled, that is, the monitoring-enabled attribute of the monitoring-service element is true. However, the default monitoring level for individual modules is OFF. This subcommand used with the --modules option can enable monitoring for a given module by setting the monitoring level to HIGH or LOW. If level is not specified when running the subcommand, the level defaults to HIGH.

The specific meanings of HIGH or LOW are determined by the individual containers. For a list of monitorable modules, see the --modules option in this help page.

An alternative method for enabling monitoring is to use the set subcommand. In this case, the server must be restarted for changes to take effect.

This subcommand is supported in remote mode only.

Options

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin(1M) help page.

--help
-?

Displays the help text for the subcommand.

--target

Specifies the target on which to enabling monitoring. Valid values are as follows:

server

Enables monitoring for the default server instance server and is the default value.

configuration-name

Enables monitoring for the named configuration.

cluster-name

Enables monitoring for every server instance in the cluster.

instance-name

Enables monitoring for a particular server instance.

--mbean

Enables Mbean monitoring. Default value is false.

--dtrace

Only usable if the DTrace Monitoring module is present. Enables Oracle Solaris DTrace monitoring. Default value is false.

--modules

Enables specified module or modules by indicating monitoring level. Valid levels are OFF, HIGH, LOW. If level is not specified, the default setting is HIGH. Multiple modules are separated by : (colon). Monitorable modules include connector-connection-pool, connector-service, ejb-container, http-service, jdbc-connection-pool, jersey, jpa, jms-service, jvm, security, thread-pool, transaction-service, web-container, and web-services-container. Additional modules can be listed by using the get subcommand.

--pid

Specifies the Eclipse GlassFish JVM process identifier (PID). When monitoring is enabled, the btrace-agent is attached, based on the specified PID. Need to specify only in exceptional cases when the system cannot determine the PID. In this situation, the subcommand prompts for the PID of the corresponding Eclipse GlassFishprocess.

--options

Sets the following btrace-agent options:

debug

Enables debugging for BTrace. Default value is false.

Examples

Example 1   Enabling the Monitoring Service for Eclipse GlassFish

This example enables monitoring for Eclipse GlassFish in general by setting the enable-monitoring flag to true (default is true).

asadmin> enable-monitoring
Command enable-monitoring executed successfully

Example 2   Enabling Monitoring for the Web and EJB Containers

This example enables monitoring for specific containers by setting their monitoring levels.

asadmin> enable-monitoring --modules web-container=LOW:ejb-container=HIGH
Command enable-monitoring executed successfully

Example 3   Turning on Debugging for Monitoring

This example turns on debugging.

asadmin> enable-monitoring --options debug=true
Command enable-monitoring executed successfully

Exit Status

0

subcommand executed successfully

1
