Situation Status Tree

Edit online

This customizable workspace displays OMEGAMON situations in a tree structure on your OMEGAMON enhanced 3270 User Interface (enhanced 3270UI). Through the Status Tree, you can see a complete picture of your enterprise monitoring status.

OMEGAMON monitoring agents generate events when certain performance thresholds, which are defined in your OMEGAMON Situations, are exceeded. You are able to view these situations through the Situation Status Tree. You can navigate to the Situation Status Tree the following ways:
  • Issue the events or alerts command from any workspace
  • Expand the HELP menu and select 10. Events Console
  • Issue an n.e fast path mnemonic in the action bar in the upper left hand portion of your screen
  • Expand the Enterprise Status branch in the Help and Workspace Directory. Drill down on KOBSITST
Note: To view and customize a Situation Status Tree, you must have OMEGAMON Dashboard Edition on z/OS V5.3.0 installed, and APARs OA48298 (PTF TBA) and OA47760 (PTF UA7724) applied.

The status tree is an outline in which you can expand and collapse different branches in the tree. You expand and collapse branches to see greater or fewer details about the Situations that make up the status tree. The status tree can be compared to the Tivoli Enterprise Portal (TEP) Navigator.

Branches have a plus sign (+) or minus sign (-) near the left edge whenever that branch contains any children. The children for a branch are visible when a minus sign (-) is displayed.

Enter a "/" in the Options field to display the pop-up menu of Status Tree Options. From this panel you can customize how your status tree is displayed. You can adjust the hierarchy of your branches, choose hour and date display formats, and adjust the width of your history columns.

With the Status Tree, you have flexibility similar to the TEP Navigator and TEP Custom Navigator views. You can group together situations based on Managed System Name or you can group situations together based on any combination of Managed System Name (msn), Situation Name (sit), Display Item (atom), Managed System Group (msl), and Affinities (aff).

For example, to create a part of the Status Tree where only situations that match a certain naming convention are displayed, you could supply a Status Tree filter like this:
{"type":"sit", "filter":{"sit":"My_SITNAMEs_xxx.*"}}

The Situations that are displayed in a Status Tree are ones that have become 'true' at some point within the time intervals being monitored. Enhanced 3270UI configuration values can be used to control the time span (minutes, hours or days) of situation data used for the Status Tree displays. When you change any of these configuration values, you must restart the enhanced 3270UI address space for the new values to be implemented.

Using the Status Tree, you are able to see which Situations are currently true, and which Situations have been true over some past time span. Viewing historical data helps you to more fully monitor the status of your systems and applications.

Example:

You can configure the Status Tree data collection to cover three days. Then on a Monday morning, for example, the system shows situation history since Friday morning. You can then select a particular status cell of interest, to get details of the situation history behind that status cell. If a status cell is red in a Sunday evening time slot, which might mean a critical problem, you can immediately drill down to the situation details that cover that point in time. The situation details tell you all the OMEGAMON values collected for that situation at that point in time. These details help you diagnose what was occurring in your environment.

The enhanced 3270UI provides a default Enterprise Status Tree that automatically discovers all of the OMEGAMON situations defined on your system; that is, defined to whichever Hub TEMS you are using. The default Enterprise Status Tree displays Situations in a hierarchy that consists of branches, where each branch is a different OMEGAMON performance monitor. For example, one branch is for the CICS® version of OMEGAMON, another is for z/OS®, and so on.

For more information on customizing the Status Tree, expand the New Features branch in the Help and Workspace Directory (KOBHLDIR) and select Status Tree to reach the KOBHLRTT workspace. For more information on reaching this workspace, see Help and Workspace Directory.
