8 Combine Mnesia with SNMP

8.1 Combine Mnesia and SNMP

Many telecommunications applications must be controlled and reconfigured remotely. It is sometimes an advantage to perform this remote control with an open protocol such as the Simple Network Management Protocol (SNMP). The alternatives to this would be the following:

• Not being able to control the application remotely
• Using a proprietary control protocol
• Using a bridge that maps control messages in a proprietary protocol to a standardized management protocol and conversely

All these approaches have different advantages and disadvantages. Mnesia applications can easily be opened to the SNMP protocol. A direct 1-to-1 mapping can be established between Mnesia tables and SNMP tables. This means that a Mnesia table can be configured to be both a Mnesia table and an SNMP table. A number of functions to control this behavior are described in the Reference Manual.
