At the start of every month, we run a SQL query to determine the amount of email alerts sent in the previous month. Over the last two months, the amount has permitted. Here are the numbers:
November | December | January | February |
4304 | 6466 | 591 | 31 |
The only major thing we did was upgrade NPM, NTA and SAM in December. Could that be the cause of the massive drop? Any ideas on how to determine the cause and verify it?
