NMC-RX 7.3.x User Guide, Vol. 2 > Configuring NMC-RX Services Using the Resource Configurator > Configuring the Polling Service

Configuring the Polling Service

The Polling Service is an application that collects status information about managed devices by means of SNMP and redistributes that information to network management clients. This service eliminates the need for every client to poll devices individually for status and reduces the SNMP load placed on managed devices. The status must be updated frequently to maintain an accurate view of the device. The Polling Service also maintains a log detailing client connections and polling problems that arise.

You can access the Polling Service parameters from the NMC-RX Resource Configurator dialog box. For more information, see Configuring the Settings in the NMC-RX Resource Configurator Dialog Box.

You can access additional parameters from the Polling Service tab. The Polling Service tab appears when you choose NMC-RX Application Settings from the Configuration menu in either the Network Workshop or the Device Workshop. For more information, see Configuring the Settings in the Polling Service Tab.

Configuring the Settings in the Polling Service Tab

NOTE: The Security privilege is required to access the Polling Service tab. For more information, see NMC-RX User Guide, Vol. 1, Chapter 8, Configuring Security Settings.

To configure the settings in the Polling Service tab:

1. From either the Network Workshop or the Device Workshop, choose Configuration > NMC-RX Application Settings, and then click the Polling Service tab.
2. Set the parameters (Table 76).
   
   
   Table 76: Polling Service Parameters

   Parameter	Default	Description
   SNMP Settings User Profile	admin	Specifies which user profile to use for SNMP settings.
   RMI Registry Port	1099	Port with which the Polling Service registers. This port is set during installation.

   
   
   

   NOTE: If you change the RMI Registry Port value, a warning dialog box appears prompting you to shut down and restart the Polling Service for the change to take effect.

   
   

If you set SNMP settings as a Polling Service user, the settings are used by the Polling Service when communicating by means of SNMP.

3. When you are done, click Save.

Viewing a User Profile

To view a user profile:

1. In the Polling Service tab, select a user profile from the SNMP Settings User Profile field.
2. Click View.

The View User Profile dialog box opens.

For information about configuring a user profile, see NMC-RX User Guide, Vol. 1, Chapter 8, Configuring Security Settings.

Getting Status Information

When the Polling Service is running, the system folders and the device and module icons change color to indicate the status of each device. Text labels to the right of the module type denote the status for a slot. See Table 77 and Table 78 for color and text status explanations.

 Table 77:  Color Status Indicators 

 Color
 Meaning

 Blue

 No connection is made between the Polling Service and the device.
 NOTE: This color is not used for modules.


 Gray

 The Polling Service has not reported any status for the device or module. Also, when polling is not enabled in the NMC-RX application, all device or module icons are gray.
 NOTE: This color should persist only when an unreachable device is being polled for the first time, in which case it will turn blue after approximately 75 seconds. 


 Green

 Device, module, or port is OK.


 Red

 Device, module, or port has failed.


 Yellow

 A warning that something is not right with the device or module. For example, the device has a problem with one or more, but not all, modules, or the modules have not finished booting and initializing.


 Cyan

 A failure that does not affect service; for example, a port in the administrative down state.



 

 Table 78:  Text Status Labels 

 Label
 Meaning

 EMPTY

 Slot does not contain a module.


 Standby

 Module is the spare for its redundancy group.


 Offline

 Module is present but currently offline.


 Update

 Module has an operational status of online but was not discovered by the Config Sync Services during the last discovery. Perform an update on this module.


 Mismatch

 Current module is different from the one discovered earlier. Perform an update on this module.


 Missing

 Module that was discovered earlier has been removed.


 Spared for by N

 Module has failed, and module N has taken over.



 

Locating the Polling Service Log

When the Polling Service is running, it creates a log file (pollingServer.log). This log file is located in the log directory of the NMC-RX home directory of the system on which the Polling Service is running.
