Overview of SNMP and MIBs in Log Central

SNMP lets you monitor and manage log resources from an SNMP-compliant system manager. You can configure the following types of SNMP traps that are generated for incoming messages:

• Basic traps

  Basic traps are defined in the Basic Trap Configuration window in the Log Central Console. The Central Collector generates an SNMP trap when it receives a log message that is mapped to an SNMP trap.

• Advanced traps

  Advanced traps are defined in filters in the message configuration file. A Data Collection Agent generates an SNMP trap when it receives a message that matches the filtering criteria.

An SNMP trap consists of variables defined in a Management Information Base (MIB). A MIB describes the attributes of a managed resource in a way that an SNMP management system can understand. Log Central provides the Log Central Traps MIB, which is in the bea_lc_trap.asn1 file. This MIB contains Log Central attributes that are used as variables in the SNMP traps. For more information about the Log Central Traps MIB, see MIB Reference.

Setting Up SNMP Management

To set up Log Central for monitoring by an SNMP management system:

1. Define the destination for SNMP traps in the trap configuration file.

   The trap configuration file defines the machine and port that Log Central components use as the destination for SNMP traps. By default, this is the local host. Edit this file to point to the correct destination for the traps. For more information, see Configuration Files.

2. Configure the management system to recognize the enterprise of the Log Central traps.

   The enterprise name is beaSystemDescr and the OID is .1.3.6.1.4.1.140.1.1.

3. Configure the management system to respond to Log Central traps.

   You can change the way that Log Central SNMP traps are displayed on your management console. You can also change the actions that the management system takes in response to specified events.

4. Determine which log messages that enter the Log Central system should generate SNMP traps.

5. If desired, configure basic SNMP traps.

   Use the Basic Trap Configuration window, which is in the Log Central Console, to map log messages to SNMP traps. For information about the Log Central Console, see the Log Central Online Help.

6. If desired, configure advanced SNMP traps.

   For information about creating filters to specify advanced criteria for triggering SNMP traps, see Creating Filters.

What Traps Are Generated?

The following table describes the SNMP traps that Log Central generates.

Table 8-1 Generated SNMP Traps

Type of Trap	Description	Trap Value
Basic SNMP traps	These traps are generated by the Central Collector for incoming messages	To configure these traps, use the Basic Trap Configuration window as described in the Log Central Online Help. If you enable a trap based on a message definition, set the Trap Enabled field to YES and define the trap value in the Trap ID field. If you enable a trap based on severity, define the trap value in the Trap Configuration tab in the Basic Trap Configuration window. If you enable a trap based on a message definition and severity, the generated trap number is the one defined in the message definition Trap ID field even if the trap is generated because of severity.
Advanced SNMP traps	These traps are generated by the Data Collection Agents for incoming messages	To configure these traps, create filters as described in Creating Filters. Define the trap value in the TRAPID action statement.
