Trap Status Test

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.

Target of the test : A Hitachi AMS storage device

Agent deploying the test : An external agent

Outputs of the test : One set of results for each of the traps configured for the storage device monitored.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed


The host for which the test is to be configured.

Source Address

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

OID Value

By default, this parameter is pre-configured with a comma-separated list of Display name:OID pairs returned by the traps for specific failure events/conditions.

The DisplayName in every pair will appear as descriptors of this test in the monitor interface.

You can, if you so wish, override this default specification by appending more DisplayName:OID pairs to the pre-configured list. This way, you can instruct the test to receive traps for failure conditions that are of interest to you. For example, say you want to capture the traps generated for inbox failure on the target Hitachi AMS storage device. To achieve this, you need to append an entry of the following format: DisplayName:OID-any. Typically, the DisplayName can be any meaningful text string that qualifies the failure condition that is to be captured. Since our example seeks to capture inbox failure condition, let us use 'Inbox failure' as the appropriate DisplayName. The OID that reports high temperature on the target storage is . Therefore, the entry you need to append to the default list will be: Inbox Failure:. Similarly, you can append more entries. However, make sure that the new entries are also comma-separated.


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*,*.*, where * indicates leading and/or trailing spaces.

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.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise 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.

Measurement Description Measurement Unit Interpretation

Number of messages

Indicates the number of failure messages for each of the traps that are configured for the storage device being monitored.


The detailed diagnosis of this measure, if enabled, will reveal the details reported by the SNMP agent via traps – the details include the time at which the SNMP trap was received, the IP address of the trap sender, the trap type, and the contents of the trap. If the ShowOID parameter is set to true, then the contents of the trap (i.e., the Trap Details column) will display the OID and its value. If the flag is set to false instead, only the values will be displayed in the Trap details column and not the OIDs.
