We are using the LMS 3.1 . Here we have around 20 numbers of Notification and Email notification group .Recently we have got a complaint like some users ( or IDs) in a particular email group not receiving mails .
So we have checked SMTP server and created a new notification group and included this IDs there in the new notification gorup .But that ids are receiving mails in this group .
Can any one tell me the way for tracing this email triggering is happeing or not with ids in LMS .
Enable Notification Services debugging under DFM > Configuration > Other Configurations > Logging. Once an event or alert is generated which should match a configured email notification subscription, check the NMSROOT/log/dfmLogs/NOS/nos.log to see if the emails were sent correctly.
This indicates a communications problem between DFM and your SMTP server. The only way to troubleshoot this further is to get a sniffer trace of TCP port 25 traffic to the SMTP server when DFM fires off an email notification.
Assuming that you completely disabled SNMP for one DFM polling cycle, you should have received an event in your Alerts and Activities Display. If so, then you should have seen a notification go out. Typically, when I troubleshoot such problems, I check the nos.log in parallel with the sniffer trace so I can correlate what's going on. It's not clear from your description that adequate testing was done.
You might consider opening a TAC service request so that this problem can be analyzed in real time.
