Most people don’t think of this but the system parameters @@cpu_busy, @@io_busy and @@idle overflow after about 49 days. If you depend on any of them for determining how busy your SQL Server has been you should reboot monthly. They only get reset with you reboot or restart SQL Server services.

It would be nice if there was some way of manually resetting them. Please let me know if you or anyone has found a way to reset them.

Rob

Ya not an addiction, but there are many things that you can make a vide list.
Sharing main categories
1. Server/Configuration level (file physical locations, buffer management, memory management, cache management, in-memory objects and more…)
2. Database level (starting with defining object names, indexes, fragmentation, heap, partitioning, columnar configuration, multithreading processing and many more…)
3. Hardware level (disk type, network type, server-client locations, ip-address, SSL connections, MSDTC, data pipelines and many more…)

Defrag
Create missing index, drop unused index
Capture running queries and tune them
Anything else?

Main app is a vendor app that keeps alive the connection to SQL Server.
It took me a lot of time to understand that tempdb is growing to the point where temp tables wait for others to drop because nothing get realease until the user is shutting down his PC – and no one does.
I have incorporated kill to all user sessions on the DB at 3am everyday.
If you need to release activity – that is a better alternative than restarting SQL Server.
