Configuration
of NscTrapsTest
The NscTrapsTest reports the count of SNMP trap messages sent on account of errors in the Hitachi USP SAN device. The parameters associated with this test are as follows:
-
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 text box, specify a comma-separated list of IP addresses or address patterns of the hosts sending the traps. 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.
A * 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.
-
Selecting the TRUE option against SHOWOID will ensure that the detailed diagnosis of this test shows the OID strings along with their corresponding values. If you select FALSE, then the values alone will appear in the detailed diagnosis page, and not the OIDs.
By default, the TRAPOIDS 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.
The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

To make diagnosis
more efficient and accurate, the eG system embeds an optional
detailed diagnostic capability. With this capability, the eG
agents can be configured to run detailed, more elaborate tests as
and when specific problems are detected. To enable the detailed
diagnosis capability of this test for a particular server, choose the On option against DETAILED
DIAGNOSIS. To disable the capability, click on the Off
option.
The option to
selectively enable/disable the detailed diagnosis capability will
be available only if the following conditions are fulfilled:
-
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.
