Overview

SNMP Managers are the network managers to which Universal Controller sends SNMP notifications.

Note

Universal Controller uses SNMPv1 for its SNMP Managers.

SNMP Managers can receive SNMP notifications when:

An Agent or OMS Server goes down or comes back up.
A Cluster Node goes Offline or becomes Active.
An SNMP Notification is associated with a task.

Note

SNMP Notifications on Cluster Nodes cannot be exported; therefore, they cannot be imported. You must set up new SNMP Notifications for Cluster Nodes whenever an export / import has been run.

Creating an SNMP Manager

Step 1	From the Agents & Connections navigation pane, select System > SNMP Managers. The SNMP Managers list displays. Below the list, SNMP Manager Details for a new SNMP Manager displays.
Step 2	Enter / select Details for a new SNMP Manager, using the field descriptions below as a guide. Required fields display an asterisk ( * ) after the field name. Default values for fields, if available, display automatically. To display more of the Details fields on the screen, you can either: Use the scroll bar. Temporarily hide the list above the Details. Click the button above the list to display a pop-up version of the Details.
Step 3	Click a button. The SNMP Manager is added to the database, and all buttons and tabs in the SNMP Manager Details are enabled.

Note

To open an existing record on the list, either:

Click a record in the list to display its record Details below the list. (To clear record Details below the list, click the New button that displays above and below the Details.)
Clicking the Details icon next to a record name in the list, or right-click a record in the list and then click Open in the Action menu that displays, to display a pop-up version of the record Details.
Right-click a record in the a list, or open a record and right-click in the record Details, and then click Open In Tab in the Action menu that displays, to display the record Details under a new tab on the record list page (see Record Details as Tabs).

SNMP Manager Details

The following SNMP Manager Details is for an existing SNMP Manager. See the field descriptions, below, for a description of all fields that display in the SNMP Manager Details.

For information on how to access additional details - such as Metadata and complete database Details - for SNMP Managers (or any type of record), see Records.

SNMP Manager Details Field Descriptions

The following table describes the fields, buttons, and tabs that display in the SNMP Manager Details.

Field Name	Description
Details	This section contains detailed information about the SNMP Manager.
Name	Name used within the Controller to identify this resource. Up to 40 alphanumerics. It is the responsibility of the user to develop a workable naming scheme for resources.
Version	System-supplied; version number of the current record, which is incremented by the Controller every time a user updates a record. Click the Versions tab to view previous versions. For details, see Record Versioning.
Description	Description of this record. Maximum length is 255 characters.
Member of Business Services	User-defined; Allows you to select one or more Business Services that this record belongs to. (You also can Check All or Uncheck All Business Services for this record.) You can select up to 62 Business Services for any record type, and enter a maximum of 2048 characters for each Business Service. If the Business Service Visibility Restricted Universal Controller system property is set to true, depending on your assigned (or inherited) Permissions or Roles, Business Services available for selection may be restricted.
Manager Address	Name or IP address of the SNMP Manager.
Manager Port	Port used by the SNMP Manager.
Trap Community String	Used by the trap receiver to determine which traps to process. Default is public.
Metadata	This section contains Metadata information about this record.
UUID	Universally Unique Identifier of this record.
Updated By	Name of the user that last updated this record.
Updated	Date and time that this record was last updated.
Created By	Name of the user that created this record.
Created	Date and time that this record was created.
Buttons	This section identifies the buttons displayed above and below the SNMP Manager Details that let you perform various actions.
Save	Saves a new SNMP Manager record in the Controller database.
Save & New	Saves a new record in the Controller database and redisplays empty Details so that you can create another new record.
Save & View	Saves a new record in the Controller database and continues to display that record.
New	Displays empty (except for default values) Details for creating a new record.
Update	Saves updates to the record.
Copy	Creates a copy of this SNMP Manager, which you are prompted to rename.
Delete	Deletes the current record.
Refresh	Refreshes any dynamic data displayed in the Details.
Close	For pop-up view only; closes the pop-up view of this SNMP Manager.
Tabs	This section identifies the tabs across the top of the SNMP Manager Details that provide access to additional information about the SNMP Manager.

MIB File

A MIB file contains the translation of the SNMP notifications sent to the SNMP Manager by the Controller.

A sample MIB file, OPSWISE.MIB.txt, is shipped with all Universal Agent for Windows and UNIX packages.

MIB and SNMP Protocol

SNMP protocol is a simple UDP package containing a set of dot-separated characters defined as ObjectID.

You can use the MIB file to set up the corresponding options Tree; the numbers will tell the server which line to go down. You then can look up inside the server for those results or, more importantly, define alerts on the decision option of the tree-structure that you defined with the MIN file.

If you have a more graphical server, you also may have a GUI showing the different parts of your trees in diagrams or other types of reporting.

SNMP protocol is, in effect, an external Alarm/(simple up to rather complex) Reporting System that searches for the Return Code (Success or Failure) of a task, rather than the actual output of the task. It could tell the Operator, for example: the Return Code is not as expected, add paper to the printer, the machine is low on disk space, or the server just booted up. These messages can be as descriptive as defined and, of course, will depend on the logging capability of the corresponding manager, which in our case is the Controller. It can be thought of as a centralized Information system, where quite a lot of tools and hardware can use for status exchange.

MIB File Location

The MIB file for both UNIX and Windows are included in the samp directory (UNIX) and samples directory (Windows) for Universal Automation Center Agent (UAG):
