Viewing Comprehensive Monitoring Data

By applying the list and get subcommands against the tree structure using dotted names, you can display more comprehensive monitoring data, such as a description of each of the statistics and its unit of measurement.

The following topics are addressed here:

• Guidelines for Using the list and get Subcommands for Monitoring

• To View Comprehensive Monitoring Data

• Comprehensive Monitoring Statistics

Guidelines for Using the list and get Subcommands for Monitoring

The underlying assumptions for using the list and get subcommands with dotted names are:

• A list subcommand that specifies a dotted name that is not followed by a wildcard (*) lists the current node’s immediate children. For example, the following subcommand lists all immediate children belonging to the server node:

  list --monitor server

• A list subcommand that specifies a dotted name followed by a wildcard of the form .* lists a hierarchical tree of child nodes from the specified node. For example, the following subcommand lists all children of the applications node, their subsequent child nodes, and so on:

  list --monitor server.applications.*

• A list subcommand that specifies a dotted name preceded or followed by a wildcard of the form *dottedname or dotted * name or dottedname * lists all nodes and their children that match the regular expression created by the specified matching pattern.

• A get subcommand followed by a .* or a * gets the set of attributes and their values that belong to the node specified.

For example, the following table explains the output of the list and get subcommands used with the dotted name for the resources node.

Table 8-4 Example Resources Level Dotted Names

Subcommand Dotted Name Output list --monitor server.resources List of pool names. list --monitor server.resources.connection-pool1 No attributes, but a message saying “Use get subcommand with the --monitor option to view this node’s attributes and values.” get --monitor server.resources.connection-pool1.* List of attributes and values corresponding to connection pool attributes.

For detailed information on dotted names, see the dotted-names(5ASC) help page.

To View Comprehensive Monitoring Data

Although the monitor subcommand is useful in many situations, it does not offer the complete list of all monitorable objects. To work with comprehensive data for an object type, use the list --monitor and the get --monitor subcommands followed by the dotted name of a monitorable object.

Before You Begin

A monitorable object must be configured for monitoring before you can display information about the object. See To Enable Monitoring if needed.

1. List the objects that are enabled for monitoring by using the list(1) subcommand.

   For example, the following subcommand lists all components and services that have monitoring enabled for instance server.

   asadmin> list --monitor "*"
   server.web
   server.connector-service 
   server.orb 
   server.jms-serviceserver.jvm
   server.applications
   server.http-service
   server.thread-pools

2. Get data for a monitored component or service by using the get(1) subcommand.
