This section uses two sample problems to discuss ways to approach unexpected real-time analysis results. One problem deals with system availability monitoring (SAM), the other with MAS resource monitoring (MRM).
A CICS® system is known to be running and short on storage, yet the condition does not show up in the EVENT view.

In the example shown in Figure 59, the SOS condition is controlled by an action definition called SOSPRI1, and the other conditions assume the default actions. The default action is to issue a CICSPlex SM EVENT and to send condition entry and condition exit WTO messages.

In the example shown in Figure 60, no CICSPlex SM event is to be viewable from the EVENT view.
MAS resource monitoring (MRM) can be used to generate an event whenever any of a particular group of transactions is disabled in a particular MAS. The LOCTRAN view (with scope set to that MAS) shows that one of the transactions is disabled, yet no event shows up in the EVENT view.
27FEB2005 04:53:08 ----------- INFORMATION DISPLAY --------------------------- COMMAND ===> SCROLL ===> CURR WIN ===> 1 ALT WIN ===> W1 =RTAACTV===========EYUPLX01=EYUMAS1A=27FEB2005==04:53:08=CPSM====6========= CMD Name System Status Period Rate Action Def --- -------- -------- --------- -------- ----- -------- Type--- DSAGETMN EYUMAS1A PENDING TVSHIFT2 60 DSAGMACT RTADEF TRANDIS EYUMAS1A ACTIVE 60 DSALWACT RTADEF LFILEDEL EYUMAS1A PENDING TVSHIFT2 300 LFILDACT RTADEF LFILEOPN EYUMAS1A ACTIVE 300 LFILOACT RTADEF PGMUSE EYUMAS1A ACTIVE 60 PGMUSACT RTADEF PGM1 EYUMAS1A PENDING TVSHIFT2 60 PGMUSACT RTADEF
If the analysis definition is not in the list, or is in the list with a PENDING status, that explains why nothing shows up in the EVENT view. The PENDING status indicates that the analysis definition is not within the Period shown. Absence from this active list indicates the analysis definition was either discarded (by use of the DSC line command on the RTAACTV view) or never installed.
Here are some points to consider:
The sample interval affects how soon the occurrence of a particular condition (such as a transaction becoming disabled) results in a real-time analysis notification. Also keep in mind that there are two sample intervals: the evaluation definition has a sample interval, which determines how often a resource is sampled, and the analysis definition has a sample interval, which determines how often an evaluation expression is evaluated.
An analysis definition’s entry and exit intervals have an effect on when a real-time analysis notification follows the occurrence of a certain condition.
You should ensure that the action definition associated with an analysis definition is set up to deliver the action that you expect. It is possible that a notification results in an SNA generic alert and not in an external message or a CICSPlex SM event.
