Understanding Event Severity

The events forwarded to the ObjectServer are displayed on the Netcool/OMNIbus console with one of the following

severities:

• Normal—Event with successful operation of a component, such as a power supply turning on, or a sensor

reading returning to normal.

• Warning—Event that is not necessarily significant, but may indicate a possible future problem, such as crossing

a warning threshold.

• Critical—Event that indicates actual or imminent loss of data or loss of function, such as crossing a failure

threshold, or a hardware failure.

• Indeterminate—Event with unknown severity. Also, a resolution event that clears the problem event is initially

displayed as indeterminate and then changed to normal, when the alert type of the event is Resolution.

Event Auto Correlation

The Dell OpenManage Connection supports auto correlation of events on Dell servers and EqualLogic systems. When

the ObjectServer receives OMSA, OMSS, or EqualLogic events, appropriate triggers are automatically invoked to

correlate the events.

The Dell OpenManage Connection automatically correlates the following events:

• Problem event with its corresponding clear event — OMSA, OMSS, and EqualLogic events support this event

correlation. The IBM generic_clear trigger correlates the OMSA, OMSS, and EqualLogic problem events

with its corresponding clear event when the problem is rectified.

• Problem event with another problem event — OMSA and EqualLogic events support this event correlation. The

dell_omsa_clear trigger correlates the OMSA problem event by another problem event. The

dell_equallogic_clear trigger correlates the EqualLogic problem events.

• Duplicated problem event with another problem event — OMSA and EqualLogic events support this event

correlation. The dell_omsa_deduplicate_clear trigger correlates the OMSA problem events. The

dell_equallogic_deduplicate_clear trigger correlates the EqualLogic problem events.

NOTE: The normal to normal event correlation is not supported as Netcool/OMNIbus periodically clears the

normal events. For more information on OMSA and OMSS event correlation, see

EqualLogic event correlation, see EqualLogic Alert Correlation.

Dell OpenManage Server Administrator Console

The Dell OpenManage Connection enables you to launch the OMSA console to get more information about the Dell

system you are monitoring. You can launch the OMSA console from the desktop event list or from the Active Event List of

the web GUI.

NOTE: Practical Extraction and Report Language (Perl) is required for the execution of Common Gateway Interface

(CGI) scripts in web GUI. If Perl is installed in a nonstandard location, then the CGI scripts do not function properly.

Always ensure that the paths to the resources in the CGI scripts are correct. The standard installation location of

Perl on systems running the Windows and Linux operating system is C:\Perl\bin\perl.exe and /usr/bin/perl

respectively. For more information, see the

IBM Tivoli Netcool/OMNIbus Administration Guide.
