Configuration of CompFailureTest

This test intercepts the traps sent by the storage system, extracts information related to hardware errors/failures from the traps, and reports the count and detailed description of these trap messages to the eG manager. This information enables administrators to detect current and potential hardware failures, understand the nature of these failures, and accordingly decide on the remedial measures.

Note:

Before attempting to configure this test, ensure that the NetApp Managability SDK (NMSDK) is available on the eG remote agent host. Click here to know more about how to configure the eG agent to use the NMSDK.

The default parameters associated with this test are:

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

  • Specify the host for which the test is to be configured in the HOST text box.

  • 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 Enterprise suite 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. 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:

    • The eG manager license should allow the detailed diagnosis capability
    • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

  • 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.
