I'm sorry for the delay in replying to your post. When you reinstalled did you uninstall the old version? Is the new install monitoring too? / comments

SQL Monitor uses a complex data collection schedule to gather information about the entities it is monitoring. This has been designed to gain the best information at the most efficient rate, and tends to have less 'expensive' data being collected more often and more 'expensive' data collected less often. |This means that SQL Monitor will have the absolute minimal performance impact on the entities being monitored. For example, simple machine pings occur every 10 seconds, but the check for the fragmented indexes only occurs once a week (by default). This unfortunately does mean that some things are missed because the tool is unable to monitor every detail all the time. Especially for points 1 and 2 I would think that the databases alerted on the databases that were in the appropriate state at the time that the relevant detail was checked. For example, when the database state was checked, 9 databases were in a state other than Online and the others managed to slip between the gaps because the change happened between the two consecutive collections. Some further points to think about: 1. The Page Verification alert should fire when PAGE_VERIFY = NONE (or TORN_PAGE_DETECTION = FALSE for SQL 2000). Can you confirm whether this is true for all the databases? 2. For the 9 databases that were alerted on, are all the alerts now marked as Ended to reflect the Online status? 3. Has the database recently been renamed? 4. In the Configure Alert page you can select databases from the tree on the left hand side and disable alerts for them. However, some of the alerts work at the SQL Server instance level and so disabling these will disable them for the whole instance. This is why some of the alerts in the refreshed list for the database do not appear. https://documentation.red-gate.com/disp ... ing+alerts I hope this makes sense. / comments
