Runtime configuration enables you to configure the server settings and effect the changes without restarting the server. It is possible to configure network discovery, policies, and map settings for the back-end server at runtime. For more details on the runtime administration facility in Web NMS, please refer to Web NMS Runtime Administration.
Distribution-Specific Configurable Options
The Distributed Mediation Servers are deployed in various geographical locations managing various networks. These servers can be configured and managed from a single interface at runtime. In the client UI, you can select the desired Distributed Mediation Server and its corresponding nodes that are listed under each Distributed Mediation Server, and perform the available configurations. The following are some important runtime configurations that can be performed on Distributed Mediation Server and Central Server using the Runtime Administration Tool:
Distributed Mediation Server: Network/Node Discovery, Polling Configuration, Trap, and Event parsing.
Central Server: Policies, Map UI settings and MO UI settings.
Configurations can be performed for individual Distributed Mediation Servers or for all new Distributed Mediation Servers. The Runtime Administration user interface in the client, for the distributed setup, contains three components, namely the left Client Tree, the middle Distributed Mediation Server list and the data display area. The following is a screen shot of discovery configuration:
The list of Distributed Mediation Servers that have registered with the Central Server is displayed in the middle panel as shown below:
The defaultToNewProbes node, shown in the screen shot, is associated with configurations that are applicable to all new Distributed Mediation Servers. FEDms and WinDMS are two registered Distributed Mediation Servers with the default set of options. Using the Customize View button, you can customize the view of the list. On clicking this button, a dialog with options for searching, selecting, deselecting a Distributed Mediation Server is displayed as follows:
By default, the entries in the SelectedList are displayed in the Distributed Mediation Server list. These entries can be shuffled between the SelectedList and UnSelectedList by using the up and down arrows provided between the two lists. After making the required selections, this change can be applied across other services, by selecting the check box at the bottom of the dialog.
The default options provided in the UI for the Distributed Mediation Server list are Add, Delete, Copy, Paste, and Modify. The following table illustrates these options:
|
Icon |
Function |
Description |
|
|
Add |
Adds a new leaf node to the selected node. Default properties associated with the module are displayed. |
|
|
Modify |
Updates the modifications done in the selected node. |
|
|
Delete |
Deletes the selected node. |
|
|
Copy |
Copies the values associated with the selected node. |
|
|
Paste |
Assigns the values copied from another node to the selected node. |
|
|
Cut |
Removes the values associated with the selected node. |
Steps to Configure Trap and Event Parsers
Invoke the Runtime Administration tool from Tools->Runtime Administration. By default, the nodes Topology, Map, Fault, Performance, and Miscellaneous with their respective sub-nodes are present.
Choose the Fault node and expand it. The Fault node has Event Parsers and Trap Parsers as sub-nodes. The properties available for configuration are explained in Configuring Trap Parsers and Configuring Event Parsers.
On setting the parser properties, the appropriate changes will be reflected in the configuration files. You can configure the general settings either for all new Distributed Mediation Server or for a particular Distributed Mediation Server. To configure the settings for all new Distributed Mediation Servers, set the parser's properties under the defaultToNewProbes node should be set and to configure the Distributed Mediation Server-specific nodes, set the parser's properties under the Distributed Mediation Server node should be set.
For details on how to implement custom parsers, please refer to Customizing Runtime Administration.
Event Parsers
When you click the Event Parser sub-node, Distributed Mediation Server list and data display area are displayed. The Distributed Mediation Server list contains at least one node - defaultToNewProbes and nodes for Distributed Mediation Server, if any. Each of the Distributed Mediation Server list nodes has a list of default event parsers configured. When a node is selected, the corresponding values are displayed in the data display area. The add, modify, delete, copy and paste operations can be performed, and the changes can be saved by using the Apply button.
Trap Parsers
When you click the Trap Parser sub-node, Distributed Mediation Server list and data display area are displayed. The Distributed Mediation Server list contains at least one node - defaultToNewProbes and nodes for Distributed Mediation Server, if any. Each of the middle panel nodes has a list of default trap parsers configured. In the below example, one Distributed Mediation Server has been connected and the following four parsers have been configured - "coldStart", "warmStart","epgNeighborLoss", and "authenticationFailure". The UI will be as shown below:
When a configured parser is selected, the corresponding data is displayed in the data display area. To commit all the changes you have made, click the Apply button.
