Sun Management Center 3.6.1 User's Guide

Monitoring Topology Manager and Event Manager

There are five components in the server layer:

With the exception of the server, the other four components are Sun Management Center agents that are loaded with specialized modules.

The default configuration for the Topology manager and the Event manager and all other Sun Management Center agents is defined by the Agent Statistics module. This module includes features that guard against errors that can bring down the host. The default action is for the software to terminate the Topology manager process if predefined thresholds are exceeded. See Agent Statistics Module Version 2.0 for more information about the Agent Statistics module.

ProcedureTo Create a Server Component as a Monitored Object

You might want to monitor the Topology manager, Trap handler, Configuration manager, and Event manager to determine their status. The Configuration manager and the Trap handler are configured so that you do not need to perform any maintenance procedures. In addition, the default configurations of both the Topology manager and the Event manager work for most user environments. However, you can modify the default configurations for specialized environments.

  1. In the main console window, choose Create Object from the Edit menu.

    The Create Object window is displayed. By default, the tab is set to Node. For more information, see To Create a Node.

  2. Choose Sun Management Center Agent - Host from the Monitor Via menu.

  3. Type the name of the server component in the Node Label field.

  4. (Optional) Type a description of the server component.

  5. Type the name of the Sun Management Center server in the Hostname field.

  6. Type the port number for the server component in the Port field.

    Sun Management Center software uses the following default port values:

    • Agent component : port 161

    • Server trap handler: port 162

    • Server event manager: port 163

    • Server topology manager: port 164

    • Server configuration manager: port 165

    Note –

    The server component uses port 2099 by default. However, you cannot change the server component port number here.

  7. Complete this procedure with one of the following actions:

    • Click OK to create the server component object and close this window.

    • Click the Apply button to create the server component object without closing this window.

ProcedureTo Change the Registry Port Number

The Sun Management Center server includes a registry feature that enables value-added products, such as Hardware Diagnostics Suite, to register its existence with the server. By default, the registry feature uses port 5600. If this port is being used by another application, the application will fail. To change the registry port, follow these steps:

  1. Change the ServiceRegistryPort value in the /var/opt/SUNWsymon/cfg/javaserver.properties file.

  2. Change the ServiceRegistryPort value in the /var/opt/SUNWsymon/cfg/javaservice.properties file to match the value you provided in the previous step.

  3. Restart the Sun Management Center server.

    Note –

    When you set up the Sun Management Center server, the installation process prompts you to provide a different port number for the registry service, if the default port is in use.

ProcedureTo Increase the Critical Threshold for the Virtual Size Data Property in the Topology Manager

The Topology manager enables the main console window to present logical objects in a topology view. The Topology manager also provides the ability to create a logical object, such as a group, whose status summarizes the statuses of multiple managed objects.

Managed objects include networks, hosts, hardware components, and software components. The total number of objects and the contents of these objects determine the system resource requirement, for example, Virtual Size, for the Topology manager. This requirement must be less than the defaults set for the Topology manager.

If the Virtual Size of the Topology manager exceeds the default value, then the Topology manager exits with the following error message:


error excessive virtual memory use

To solve this error, increase the default virtual size as described in the following steps.

  1. Evaluate the situation carefully.

  2. Create the Topology manager monitored object.

    See To Create a Server Component as a Monitored Object.

  3. Open the Details window using one of the following methods:

    • Press mouse button 3 on the Topology manager object icon. Choose Details from the pop-up menu in the hierarchy view or the topology view.

    • Double-click the Topology manager icon.

    • Select the Topology manager icon in the main console window, then choose Details from the Tools menu.

  4. In the Browser Details window, double-click the Local Applications icon in the hierarchy (tree) view.

  5. Double-click the Agent Statistics icon in the contents view, or click the expansion icon next to the Agent Statistics icon in the hierarchy view.

    The Agent Statistics folders are displayed.

  6. Double-click the folder icon for the PA Process Statistics.

    The monitored properties are displayed in a property table.

  7. Select the Virtual Size table cell, then open the Attribute Editor through one of the following methods:

    • Press mouse button 3 in the table row, and choose Attribute Editor from the pop-up menu.

    • Click the Attributes button.

  8. Click the Alarms tab button.

    The alarm rows are displayed.

  9. Type the desired value in the Critical Threshold (>) field.

  10. Complete this procedure with one of the following actions:

    • Click OK to create a new Critical Threshold value and close this window.

    • Click the Apply button to create a new Critical Threshold value without closing this window.

ProcedureTo Change the Default Values for Smart Delete in the Event Manager

The Event manager communicates with other server components through SNMP using the default port 163. Similar to the Topology manager, the Event manager is also loaded with the Agent Statistics module. In addition, the Event manager is automatically loaded with a specialized Event Management module. The Event Management module is displayed in the Browser Details window in the Local Applications category.

The Event Management module is responsible for the overall maintenance of the event database. This module's responsibilities include purging deleted events, renaming the trash file, and Smart Delete.

Smart Delete means that Sun Management Center software automatically deletes closed, fixed, and open events from the event database after a set period of time. By default, the closed or fixed events are removed from the database after 7 days and the open events are removed after 30 days. To change these defaults, perform the following steps.

  1. Create the Event manager monitored object.

    See To Create a Server Component as a Monitored Object.

  2. Open the Details window through one of the following methods:

    • Press mouse button 3 on the Event manager icon. Choose Details from the pop-up menu in the hierarchy view or the topology view.

    • Double-click the Event manager icon in the hierarchy view or the topology view.

    • Select the Event manager icon in the main console window, then choose Details from the Tools menu.

  3. In the Browser Details window, double-click the Local Applications icon in the hierarchy (tree) view.

  4. Open the Module Editor through one of the following methods:

    • Press mouse button 3 on the Event Management module. Choose Edit Module from the pop-up menu in the hierarchy view or in the contents view.

    • Select the Event Management module in the Details window, then choose Edit Module from the Module menu.

    The Module Parameters Editor is displayed. For more information, see To Modify Module Parameters.

  5. Type the new time values into the editable fields.

    By default, the closed or fixed events are removed from the database after 7 days. The open events are removed after 30 days.

  6. To turn off Smart Delete, choose Disabled from the Smart Delete Enabled Switch menu.

  7. Click OK to accept the changes that you made and close this window.
