Foglight for Microsoft DOT NET 5.9.7.5 - Installation and Configuration Guide

Installing and Configuring Foglight for Microsoft .NET Managing .NET Agent Configurations

Switching .NET Agent Configurations

You can create or edit agent configurations through the .NET Administration dashboard before or after creating a .NET agent. If you create an agent and use the default configuration during installation, you can later create another customized configuration and assign it to the agent.
See Creating New .NET Transaction Agent Configurations or Managing .NET Agent Integration Configurations for information about creating new configurations.
This procedure describes how to switch the configuration that an agent is using to collect data after the agent and a unique configuration have been created.
To switch an agent’s configuration:
1
On the navigation panel, under Dashboards, click Application Servers > Administration > Application Servers Administration.
2
On the Application Servers Administration dashboard, in the Monitoring Agents table, click the name of the agent to which you want to assign a new configuration.
3
In the list that opens, click Switch configuration.
Depending on the type of agent you selected (transaction or counters), either the Switch Transaction Configuration or the Switch Counters Configuration dialog box opens.
 
* 
TIP: These two dialog boxes function identically. The only difference is the name, which reflects the type of agent selected.
4
Select a configuration from the list and click Switch.
A message box opens, indicating that the configuration used by the agent is updated. You do not need to restart the agent.
5
Click Close.

Understanding the Nexus and Agent-Nexus Connections for .NET Agents

Foglight for Microsoft .NET includes the Nexus, a central analytical engine that correlates data sent from multiple agents, restores and preserves the temporal order of events across all servers, and provides other basic analysis of the data. The Nexus is essential to the data management facilities of Foglight for Microsoft .NET.
Foglight creates a default Nexus as part of the installation process for Foglight for Microsoft .NET. The default Nexus controls all agent data correlation and submission unless you create another Nexus and assign agents to it instead.
 
* 
TIP: For more information about the Nexus, see the topic “Understanding the Nexus” in the Monitoring Application Servers Administration and Configuration Guide or help.
The Nexus connection is the communication link between the .NET Agent and the Nexus. It defines how the agent communicates with the Nexus and controls settings such as retry intervals and timeouts. The agent-Nexus connection is created as part of the cartridge installation process. You can also create new connections, or edit existing ones, and change which agents are using a connection by switching the agent’s Nexus connection.

Managing .NET Agent Nexus Connections

During the process of creating a .NET Agent, you assign it to an existing Nexus, and an agent-Nexus connection is created. You can also change the connection between an agent and a Nexus, or create a new connection and assign it to different agents after they have been created.
 
* 
NOTE: The Nexus is only applicable to .NET Agents that are monitoring transactions.
Creating or Editing Agent-Nexus Connection Settings
The process for creating a new agent-Nexus connection and the process for editing an existing one are very similar. The following procedure describes both options and any differences between them.
To change agent Nexus connection settings:
1
On the navigation panel, under Dashboards, click Application Servers Administration.
2
On the Application Servers Administration dashboard, click .NET Administration.
3
The .NET Administration dashboard opens with the Integration Configurations tab displayed.
4
On the Integration Configurations tab, click Manage Nexus connections.
The Manage Nexus Connections page opens.
This page lists all existing agent-Nexus connections and the location of the Nexus. From here, you can edit an existing connection, or create a new one.
5
To edit an existing connection, click the name of the connection, then click Edit.
or
To create a new connection, click New.
The Nexus Connection dialog box opens.
6
On the Locations tab, you can add Nexuses that the agent should attempt to connect to, in the order that you want. The agent attempts to connect to each Nexus in turn until a successful connection is established.
Click Add Nexus location and select a Nexus from the list.
 
* 
TIP: Use the Add custom option to define a Nexus location by listen address and port.
7
Optional — Use the up and down arrows to change the order in which the agent attempts the Nexus connections.
8
Click the Advanced tab.
9
Edit the connection settings as necessary. Click the info icon () to view a detailed description of the setting and its effects.
10
New Nexus connections only — If you want to reuse this connection and assign it to other agents, type a unique name in the Save as box.
11
Click Save.
The Manage Nexus Connections page refreshes. Any changes you have made to the Nexus location are listed in the Nexus Locations column. The time and date in the Last Modified column are also updated.

Managing Collection Schedules

Use the Manage Collection Schedules dashboard to create and manage the schedules that define the frequency at which the .NET performance counters only agents collect data.
Agents use the default schedule unless you create and assign a different collection schedule through this view.
