Configuring the On Demand Port on the Agent Manager Concentrator

If a firewall is installed between the Management Server and the Agent Manager, the bidirectional RMI connection shown in the figure above will not be possible because RMI requests require direct connection.

This issue can be resolved by creating an RMI proxy server on the concentrator — an Agent Manager instance that works similarly to an HTTP proxy. This RMI proxy server can be configured to accept RMI requests from the Management Server and direct them to the Agent Manager instances (called downstream instances). For additional details about the concentrator, see Configuring an Agent Manager Instance as a Concentrator in the Agent Manager Installation Guide.

A concentrator agent, created specifically for Foglight for Oracle, allows controlling the RMI server so that the server is initialized (starts collecting data) when the agent starts, and stops when data retrieval by the agent is brought to an end. The agent, which is created manually by the user, requires configuring the following parameters:

•
A list of the downstream hosts that are connected through the concentrator
•
The RMI port number

Each time the Foglight Management Server sends an RMI request, the list of downstream hosts submitted by the concentrator agent is being searched.

•
Inclusion of the target RMI server host name within this list indicates that a Foglight Agent Manager concentrator exists, in which case a connection is made to the proxy RMI server.
•
If the list does not contain the target host name, the connection is made directly to the target RMI server.
To create the concentrator agent:
1
Go to Dashboards > Administration > Agents > Agent Status.
2
Click Create Agent.
3
Select the agent type DB_Oracle_Concentrator.
4
Enter a name of your choice in the Instance Name field.
5
Click Create.
6
After the creation process is completed successfully, click OK.
To edit the concentrator agent connection details:
1
Select the newly created concentrator agent.
2
Click Edit Properties.
3
Click Modify properties for this agent only.
4
Enter the number of the proxy RMI server port, or accept the default number.
5
Enter the concentrator Foglight Agent Manager host name (optional).
6
Click Edit to edit the list of downstream Agent Managers.
7
Click Add Row.
8
Enter the name of the requested Foglight Agent Manager host.
* 
IMPORTANT: When editing the properties of the Foglight Agent Manager concentrator (Dashboards > Administration > Agents > Agent Status), the name of the Foglight Agent Manager should be entered in the Downstream FglAMs section exactly as it appears in the topology, under Home > Agents > All agents > <Agent name> > RMI data > Fglam host property. The <Agent name> parameter refers to any of the Foglight for Oracle agents that reside on the selected Foglight Agent Manager.
9
Repeat Step 7 to Step 8 as many times as required.
10
Click Save Changes.
11
Click Save at the lower right corner of the screen.
12
Click Back to Agent Status.
13
Select the newly created concentrator agent.
14
Click Activate.
15
Click OK to complete the process.
* 
IMPORTANT: In an environment that includes a Foglight Agent Manager concentrator, when upgrading the environment where the concentrator does not contain any regular agents, the concentrator is not upgraded. Therefore, after the upgrade process takes place the Foglight Agent Manager concentrator has to be deployed manually.

Installing and Monitoring a Single Oracle Instance

Enabling the Foglight Management Server to monitor Oracle instances requires the creation of the Foglight agents that monitor these instances and ensuring that these agents communicate properly with the Foglight Management Server.

Foglight for Oracle provides a graphic, intuitive method for creating and configuring multiple agents, which can be used instead of Foglight’s default method for creating agents and editing their properties using the Agent Administration dashboard. Foglight for Oracle allows you to run a wizard that provides a common entry point for adding and discovering all database instances within a user-specified range, and then configuring these instances for monitoring.

 

* 
IMPORTANT: When running Foglight for Oracle in a Federation architecture, neither the creation nor the administration of agents can be accomplished from the central Foglight Management Server (the Federation Master). These two tasks should be carried out from the stand-alone Management Servers (the Federated Children).

 

* 
NOTE: When the feature multitenant container database (CDB) architecture is enabled, the customer should create the user with "container=all".
create user c##cust identified by cust container=all;
grant connect to c##cust container=all;
To run the instance installation wizard:
1
On the navigation panel, click Homes > Databases.
2
Click Monitor > Oracle in the upper left corner of the Databases View.
The Monitor Oracle Instance dialog box appears.
* 
NOTE: If a user-defined database group is currently selected, the databases table's title displays the name of this group instead of All; however, all newly discovered or created databases are added to the general (All) group of databases.
3
Choose the agent manager on which the agent will be running The default is the agent manager with the least agents installed.
a
Click the Agent Manager Host <agent manager> link located at the top of the Oracle Connection section.
A dialog box appears with a list of all agent managers connected to the Foglight management server.
b
Select the appropriate host name and click Set.
 
* 
IMPORTANT: You have the option set this host as the default for all future installations.
4
Use the Connection Details section to select the requested method for entering connection details:
•
TNS — used for selecting a database from the tnsnames.ora file by clicking Load file.
•
Host — Manually enter Host, port and either service name or SID.
5
Use the Login Credentials section to specify the username and password to be used for monitoring the Oracle instance.
6
Use SSL: Select whether an SSL connection should be used. For details, see Defining the Connection Settings for the Monitored Oracle Instances .
7
In the Configuration section, select the Alarm Template to use for this instance. The Factory Template will be applied by default. Refer to Viewing, Creating, and Managing Alarm Templates in the Foglight User Guide for more information.
