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.
Ā
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.

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):
