SNMP Implementation (Magic xpa 2.x)

Magic xpa supports Simple Network Management Protocol (SNMP) functionality. This lets Magic xpa programs and the Magic xpa engine (the broker and the requester) send SNMP compliant messages to a monitor. It also gives the system administrator control over various Magic xpa modules via an SNMP monitor.

SNMP governs network management and monitors network devices and their functions. Once Magic xpa is SNMP enabled, the Network Management Station (NMS), also referred to as an SNMP monitor, can query and manage the Magic xpa broker (including its registered enterprise servers) and the Magic xpa broker can report traps (alarms, failures, or other exceptional events occur). Requesters and stand-alone enterprise servers, can only report traps.

Configuring Magic xpa to Work with the SNMP Monitor

1. Enable the SNMP agent. For Magic xpa to be SNMP-enabled, the SNMP agent must be installed and enabled in the operating system. When the operating system is SNMP-enabled, Magic xpa automatically installs the SNMP component in the Typical installation.
   For example, in Microsoft Windows, the Microsoft SNMP Agent service must be started.
   When the SNMP option has been selected, the installation process automatically sets the EnableAgent setting to Yes. In Windows, the SNMP service is restarted so that the changes to the Magic Requesters can take effect immediately.

2. Configure the following in the SNMP agent:

   • Security – The Community property should have Read and Write rights specified.

   • Traps – The Host Trap destination should be defined. Usually, these values are the same as the values in the Mgreq.ini file.
     

3. Install Magic xpa. The Magic xpa SNMP extension, the Mgsnmp.dll file, is placed in the Magic xpa root during installation.

4. Copy the Management Information Base (MIB) files into the NMS. Magic xpa supplies two MIB files, Magic.mib and Magic_trap.mib, located in the Magic xpa Support directory. The MIB files are compiled according to the NMS version installed.

5. To enable the MIB files to communicate, add the following keys to the registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\MAGIC\SNMP\ExtensionAgents\CurrentVersion]

"Pathname"="mgsnmp.dll"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ExtensionAgents]

"MAGICSNMP"="SOFTWARE\\MAGIC\\SNMP\\ExtensionAgents\\CurrentVersion"

6. Configure the SNMP-related settings in the Mgreq.ini and Mgrb.ini files, to specify when the Magic Requester and Magic Requester Broker send trap messages.

7. Set the SNMP Database Connections Utilization Threshold environment setting.
