The
Work with Network Nodes dialog box |
After you configure TPM
NSM Gateway with the Network Management Configuration dialog box, you can configure
the individual nodes that TPM NSM Gateway monitors in your NSM
platform. The Work with Network Nodes dialog box is the
starting point for all activities pertaining to node maintenance: adding, modifying, and
deleting network nodes. The Work with Network Nodes dialog box lists every node record in
the TPM NSM Gateway system. |
Opening the Work with Network Nodes
dialog box |
If you are using the Tivoli Network Management
Administrator profile, from the Edit menu, choose Work with Network Nodes. From the Help
menu, choose Your System Profile and follow the instructions under Work with Network
Nodes. |
Node records |
To open a problem for a node in the Tivoli
Problem Management database, a record for that node must exist. If an event is detected
for a node that does not have a record, TPM
NSM Gateway automatically adds a record for it. Because TPM NSM Gateway is designed
for maximum automation, you rarely have to manually add node
records. |
Automatic
addition of node records |
When you install TPM
NSM Gateway, a process runs that automatically adds node records for all nodes that
meet the required criteria. If a new node is added to the network after this process
occurs, the NSM
platform automatically detects it and notifies TPM NSM Gateway. TPM NSM Gateway
responds appropriately and adds the record for the node if the node meets the required
criteria. |
Logical operators for searches |
Choose one of the following logical
operators for your search:
Logical operator |

Adding
a node record manually |
This information can also be useful if you want
to modify an existing node record. To manually add a node record in TPM
NSM Gateway:
- In the Work with Network Nodes dialog box,
choose Add.
Result: The Network Node dialog box
appears.
- In the Node Name box, type the name of the node.
This name must be unique and should be a valid name on the domain name server.
Caution: Once you add a node record and choose OK, you cannot change its
name.
- In the Node Contact list, choose the name of the person who receives the notification if
there is any trap specified in the nsmnodes.conf file for the node.
- In the Node Location box, type the location identifier.
This identifies the physical location of the node. This is not the Tivoli Problem
Management location. This information is not validated; it is used for information
purposes only.
- If appropriate, select the Update from SNMP check box.
If you select this check box, the Node Contact and Node Location boxes can be updated by
information discovered by the NSM
platform through SNMP.
- If appropriate, select the Notify on Failure check box.
If you select this box, notification is sent to the node contact when a problem is opened
for the node in Tivoli Problem Management.
- If appropriate, select the Notify on Restore check box.
If you select this box, notification is sent to the node contact in Tivoli Problem
Management when the node is restored to service.
- In the Fault Severity list, select the Tivoli Problem Management Severity code to assign
to all problems related to this node.
Note: If you do not select a default severity code, the severity code
defined in the System Configuration dialog box Open tab is used.
- In the Fault Impact box, type any information that would be useful to Tivoli Problem
Management analysts if the node goes down.
When a node managed by the TPM NSM Gateway is in a fault condition, the network fault
record for the node is displayed in the Work with Network Faults dialog box in Tivoli
Problem Management and on the Gateway Module. In a network fault record, the Fault Impact
box describes the consequences of a particular node's failure.
- Choose OK.
Result: The Work with Network Nodes dialog box reappears.
Note: The Problem Configuration button is inactive when you add a
node. You must first add a node record and then edit it to set up problem configuration
for the node. See Configuring Node Problems for further
details. |
Editing
a node record |
You can edit any of the node settings, except
the node name, at any time. You may occasionally need to edit an existing node record if
you do not allow the NSM
platform to update system contact information (that is, who gets notified when a
problem is opened in Tivoli Problem Management).
To edit a node record:
- In the Work with Network Nodes dialog box,
select the node that you want to edit.
- Choose Edit.
Result: The Network Node
dialog box appears.
- Make the appropriate changes (see Adding
a node record manually).
- Choose OK.
Result: The Work with Network Nodes dialog box reappears.
|
Viewing
a node record |
The View button on the Work with Network Nodes dialog box opens the same
type of Network Node dialog box that the Add and Edit buttons opened. The difference is that
when you view the Node Information dialog box, all of its boxes are read-only. This
feature is useful when you are granting security rights to users. You can effectively
assign certain users read-only permission by allowing them to use only the View button. |
Deleting
a node record |
Node records are stored in the Tivoli Problem
Management database. To delete them, you can either access the database directly or delete
them from within TPM
NSM Gateway. In the Gateway Module, you can delete a node record at any time. When
you delete a node from the NSM
platform, its node record is not automatically removed from the Tivoli Problem
Management database. You can either retain or delete this information. If there is no
problem open for the node in Tivoli Problem Management, there is no impact to either
Tivoli Problem Management or the TPM NSM Gateway when you delete the node record.
Caution: If Tivoli Problem Management has an open problem for a node,
you can delete the node record in the TPM NSM Gateway. However, Tivoli Problem Management
does not automatically close the problem. Instead, you must manually close the problem in
Tivoli Problem Management.
Note that if a problem configuration record exists for a node that is deleted, the
problem configuration record is automatically deleted as well.
To delete a node record:
- In the Work with Network Nodes dialog box,
select the node that you want to delete.
- Choose Delete.
Result: A message appears, asking you to confirm the deletion of the node
record.
- Choose Yes.
Result: The name of the node is removed from the list.

Performing an inquiry on
the list of node records |
The Work with Network Nodes dialog box may
contain thousands of node
records. You can use the Inquiry function to display only node records with specific
characteristics. To successfully use the Network Node Inquiry dialog box, you only need
to enter search criteria for one box. However, by entering search criteria for multiple
boxes, you can narrow the list of nodes that the Work with Network Nodes dialog box
contains.
To perform an Inquiry on the list of nodes:
- In the Work with Network Nodes dialog box,
choose Inquiry.
Result: The Network Node Inquiry dialog box appears.
- From the Node Name list, select the logical operator you want to use for your search.
Select from these logical operators.
- In the Node Name box, type the name of the node for which you want to search.
You can type any alphanumeric characters for the value. However, for best search results,
specify as much of a complete value as possible. Also, if you select the = logical
operator, you can use wildcard characters to perform a more general search:
- ? is a wildcard character that substitutes for a single character. For example, M?KE
matches MIKE but not MOOSE.
- * is a wildcard character that substitutes for a single character or a string of
consecutive characters. For example, M*E matches both MIKE and MOOSE.
- From the Node Contact list, choose the logical operator you want to use for your search.
The Node Contact list contains the same logical operators that the Node Name list does.
- In the Node Contact box, type the name of the node contact for which you want to search.
The rules for the Node Name box also apply to the Node Contact box.
- From the Node Location list, choose the logical operator you want to use for your
search. The Node Location list contains the same logical operators that the Node Name list
does.
- In the Node Location box, type the node location for which you want to search. The rules
for the Node Name box also apply to the Node Location box.
- From the Fault Severity list, choose the logical operator you want to use for your
search. The Fault Severity list contains the same logical operators that the Node Name
list does. However, you cannot select case-sensitive versions of the operators for fault
severity.
- In the Fault Severity box, choose the fault severity for which you want to search from
the list. The rules for the Node Name box also apply to the Fault Severity box.
- From the Update from SNMP list, select one of the following:
- The blank space above the TRUE operator clears the Update from SNMP box.
- TRUE searches for node records that are configured to automatically
receive updated data about the node contact and node location from SNMP.
- FALSE searches for node records that are not configured to
automatically receive updated data about the node contact and node location from SNMP.
- From the Notify on failure list, select which action you want taken, if any. The list is
the same as the Update from SNMP list.
- From the Notify on restore list, select which action you want taken, if any. The list is
the same as the Update from SNMP list.
- From the Record Creation Time and Date list, select the logical operator you want to use
for your search. The Record Creation Time and Date list contains the same logical
operators that the Node Name list does.
- In the Time box, specify the time of node record creation.
To clear the Time box, close both the Network Node Inquiry dialog box and the Work with
Network Nodes dialog box.
- In the Date box, specify the date of node record creation.
To clear the Date box, close both the Network Node Inquiry dialog box and the Work with
Network Nodes dialog box.
- Choose OK.
Result: The Work with Network Nodes dialog box appears and displays all
nodes that meet the inquiry criteria.
If no node records met your inquiry criteria, then the Work with Network Nodes dialog box
does not display any node records.
