NM APPEARS TO HAVE STOPPED MONITORING SNAGRP'S

Products

• NetMaster Network Automation

Issue/Introduction

Customer reported that the bank's offices--which are SNAGRPs--were not 

being monitored on Resource Monitor. 

Customer was not sure when problem started.

Note: SNAGRPs = SNA Groups.

Environment

OS: z/OS

Release : 12.2

Component : CA NetMaster Network Automation

Cause

The original problem was that the code would set up a timer to trigger the first heartbeat 

BEFORE setting up all the APPLs to be monitored. On a long set-up (such as this case) 

the problem was that the timer would pop before the set-up was finished and would 

be missed. 

Resolution

Level 2 Support raised a fix (tested successfully at customer and published

as SO08493) that moves the setting of that initial timer to AFTER the APPL 

set-up is complete. 

This ensures that the initial heartbeat is not missed and so        subsequent 

heartbeats will occur.  

Additional Information

SYMPTOMS:
