Customer reported the following:
Some old alerts generated by OPS/MVS seem to be sent again to Spectrum console after NetMaster restarts.
In the Alert Monitor Interface (/PARMS group $AM ALERTS) we have these parameters set with these values:
Clear? ..........YES TCP/IP Inact ............WAIT
Alerts .......... ALL Forward on Update? YES
Can we work with these parameters to avoid the reported situation?
OS : z/OS
Release : 12.2
Component : CA NetMaster Network Management for TCP/IP
NetMaster Level 2 Support explained:
There is no staging of alerts. All alerts are handled at the time when the alert has been created--either
internally by NetMaster or externally via whatever source that is (OPS/MVS in this case). Everything
happens in real-time. So OPS/MVS (for whatever reason) decided to create an alert and send to Net-
Master at that moment in time.
NetMaster Level 2 Support also explained (about 3 /PARMS group $AM ALERTS parms mentioned):
Clear specifies whether to forward cleared alerts. Valid values are:
YES - Alerts for cleared alert events are forwarded
NO - Alerts for cleared alert events are not forwarded
Simply put: Clear means closed. So if a user closes an alert from the Alert Monitor then that closed
alert will either be forwarded or not based upon YES or NO setting.
This parm is necessary for those situations where alerts are forwarded to another Event Manager
and that Event Manager must keep track of open and closed alerts.
Alerts specifies how to handle alerts that were generated before alert forwarding was enabled. Valid
NEW - New alerts are forwarded only
ALL - Current alerts and new alerts are forwarded
The default is NEW as in a typical scenario--the Alert Forwarder would be started during region INIT
and at that point in time there would be no ACTIVE alerts.
By specifying ALL that typically means that the customer is updating and actioning the ALERT parm
group while NetMaster has been up and running--therefore there might be active alerts on the Alert
Monitor where it is desired that these alerts be forwarded to the nominated place.
ALL - All current alerts. This means it behaves just like when the Alert Monitor display is first
entered--all of those alerts are forwarded.
So normally the value of NEW will always suffice because it will be started before all alerts are creat-
ed during region INIT--but if a new Forwarder is created then ALL allows for sending all current Alert
Forward on Update specifies whether to perform alert forwarding when alerts are updated and when
they are created. Valid values are:
YES - Alert updates are forwarded
NO - Alert updates are not forwarded
Given that the Alert Monitor allows a user to change severity of alert--or add notes--this parm allows
the updated alert to be forwarded to nominated place with the updated alert.
