This test captures the SNMP trap messages sent out by the hardware components (such as battery, cache memory, drive, enclosure controller, fan, host controller, other enclosures, and power supply units) on the storage device, and thus enables administrators to promptly detect potential hardware failures. The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

• In the SOURCEADDRESS textbox specify a comma-separated list of IP addresses or address patterns of the hosts from which traps are considered in this test. For example, 10.0.0.1,192.168.10.*. A leading '*' signifies any number of leading characters, while a trailing '*' signifies any number of trailing characters.

• Provide a comma-separated list of OID and value pairs returned by the traps. The values are to be expressed in the form, DisplayName:OID-OIDValue. For example, assume that the following OIDs are to be considered by this test: .1.3.6.1.4.1.9156.1.1.2 and .1.3.6.1.4.1.9156.1.1.3. The values of these OIDs are as given hereunder:

  OID	value
  .1.3.6.1.4.1.9156.1.1.2	Host_system
  .1.3.6.1.4.1.9156.1.1.3	NETWORK

  In this case the OIDVALUE parameter can be configured as Trap1:.1.3.6.1.4.1.9156.1.1.2-Host_system,Trap2:.1.3.6.1.4.1.9156.1.1.3-Network, where Trap1 and Trap2 are the display names that appear as descriptors of this test in the monitor interface.

  An * can be used in the OID/value patterns to denote any number of leading or trailing characters (as the case may be). For example, to monitor all the OIDs that return values which begin with the letter 'F', set this parameter to Failed:*-F*.

  Typically, if a valid value is specified for an OID in the OID-value pair configured, then the test considers the configured OID for monitoring only when the actual value of the OID matches with its configured value. For instance, in the example above, if the value of OID .1.3.6.1.4.1.9156.1.1.2 is found to be HOST and not Host_system, then the test ignores OID .1.3.6.1.4.1.9156.1.1.2 while monitoring. In some cases however, an OID might not be associated with a separate value - instead, the OID itself might represent a value. While configuring such OIDs for monitoring, your OIDVALUE specification should be: DisplayName:OID-any. For instance, to ensure that the test monitors the OID .1.3.6.1.4.1.9156.1.1.5, which in itself, say represents a failure condition, then your specification would be:

  Trap5: .1.3.6.1.4.1.9156.1.1.5-any.

• Specifying true against SHOWOID will ensure that the detailed diagnosis of this test shows the OID strings along with their corresponding values. If you enter false, then the values alone will appear in the detailed diagnosis page, and not the OIDs.

• By default, this parameter is set to all, indicating that the eG agent considers all the traps received from the specified SOURCEADDRESSes. To make sure that the agent considers only specific traps received from the SOURCEADDRESS, then provide a comma-separated list of OIDs in the TRAPOIDS text box. A series of OID patterns can also be specified here, so that the test considers only those OIDs that match the specified pattern(s). For instance, *94.2*,*.1.3.6.1.4.25*, where * indicates leading and/or trailing spaces.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
