Switching a Nexus connection

Switching a Nexus connection

You can change the Nexus connection between an agent and a Nexus after the agent has been created. For example, you might switch the connection for performance reasons (divide up the agents) or to organize your environment (all agents monitoring a particular application use the same Nexus). Switching the Nexus connection affects all of the agents belonging to the application server integration.

To switch a Nexus connection:
1
On the navigation panel, under Dashboards, click Application Servers > Administration.
2
On the Application Servers Administration dashboard, click the Java tab.
3
On the Java Administration dashboard, click the Integration Configurations tab.
4
In the Configuration Name and Targets list, expand the configuration group (for example, WebLogic on Windows: startWebLogic) by clicking the ‘+’ sign.
5
Click the name of the application server (agent target) that you want to switch the Nexus connection on.
6
In the list that opens, select Switch Nexus Connection.
A dialog box opens, listing all the available Nexus Connections for that application server integration.
7
Select the Nexus connection that you want to switch to.
8
Click Switch to save your changes.

All of the agents within the application server integration now use this Nexus connection to communicate with the Nexus.

Updating integration configuration properties

Sometimes, due to monitored environment changes, it may be necessary to update the integration configuration properties, such as the target integration script location, or the agent or pre-instrumentor options.

To edit the integration configuration properties:
1
On the navigation panel, under Dashboards, click Application Servers > Administration.
2
On the Application Servers Administration dashboard, click the Java tab.
3
On the Java Administration dashboard, click the Integration Configurations tab.
4
In the Configuration Name and Targets list, click the name of the configuration that you want to edit (for example, WebLogic on Windows: startWebLogic).
5
In the menu that opens, click Properties.
6
In the Integration Task Properties dialog box, change the available values as necessary.
7
Click Save.
8
Restart the affected application servers.

Java EE agent logging properties

You can configure the following for logs that the Java EE agents produces:

•
Log targets, for forwarding log messages to different outputs
•
Log level (ALL, DEBUG, VERBOSE, INFO, WARN, ERROR, FATAL, and OFF) for each log target
•
The directory in which log files are created (if other than the default directory, <VERSIONED_SUBDIRECTORY>/logs)
•
A locale setting for changing the language in which log messages are written

You can also configure several log targets:

•
Console: Outputs to the application console
•
Text File: Outputs to a formatted text file
•
Serialized File: Outputs to a serialized object file
•
WebSphere: Forwards Agent messages to the WebSphere log system

Java EE agents normally have Console and Text File log targets active. The Serialized File target is active in all log-enabled applications, but its threshold is set to OFF normally. This can be overridden in release-mode by setting its threshold to something other than OFF, preferably ALL. WebSphere is active only for agents monitoring WebSphere.

Each target has a set of properties that can be set to modify its behavior. All targets have one common property: Threshold Log Level. Targets ignore log messages of a level below this threshold. Standard levels are ALL, DEBUG, VERBOSE, INFO, WARN, ERROR, FATAL and OFF, in descending order of verbosity. A threshold of OFF effectively disables a target. File-based targets do not create files when their threshold is OFF.

Create a basic log configuration as part of the agent installation process. You can edit that configuration, or create ones, at any other time.

Creating or editing logging properties

The process for creating a log configuration and the process for editing an existing one are similar. The following procedure describes both options and any differences between them.

To edit or create a logging configuration:
1
On the navigation panel, under Dashboards, click Application Servers > Administration.
2
On the Application Servers Administration dashboard, click the Java tab.
3
On the Java Administration dashboard, click the Integration Configurations tab.
4
Click Manage logging. The Logging page opens.
5
Click the name of the log that you want to edit. In the menu that opens, click Edit.
Or
Click New.
In either case, the Log Configuration dialog box opens.
* 
TIP: If you are uncertain about how to adjust these settings, click Help for an overview of log targets and their purposes.
6
Set the values for each of the logging target types: Console, Text File, Serialized File, WebSphere, and Other, as necessary. If you need more information about a particular setting, click the icon.
7
New configurations only — Type a unique and recognizable name in the Save as box.
8
Click Save.

The next time that you create an agent, you can assign the saved log configuration to it. You can also update any integrations that are already using the log configuration.

To update log settings for an existing configuration:
1
On the navigation panel, under Dashboards, click Application Servers > Administration.
2
On the Application Servers Administration dashboard, click the Java tab.
3
On the Java view, click the Integration Configurations tab.
4
In the list of Configuration Name and Targets, expand the configuration group by clicking the ‘+’ sign, then click the name of the target you want to update.
5
In the list that opens, click Update logging.
