In a previous blog post, I surfaced Azure monitor capabilities for extending observability of Azure SQL databases. We managed to correlate different metrics and SQL logs to identify new execution patterns against our Azure SQL DB, and we finally go through a new compute tier model that fits better with our new context. In this blog post, I would like to share some new experiences about combining Azure cost analysis and Azure log analytics to spot “abnormal” trend and to fix it.

The DevOps mindset mainly drove the idea to move our SQL Server monitoring to the existing Prometheus and Grafana infrastructure.

As DBA, your priority is to ensure your data are consistent, safely backed up and you get steady performance of your database. In on-prem environments, these tasks are generally performed through scheduled jobs including backups, check integrity and index / statistics maintenance tasks.

Indeed, even if the same concern and tasks remain, some of them are under the responsibility of the Cloud provider and some other ones not. If you’re working with Azure SQL databases – like me – some questions raise very quickly on this topic and it was my motivation to write this write-up. I would like to share with you some new experiences by digging into the different maintenance items. If you have a different story to tell, please feel free to comment and to share your own experience!

A quick blog post to show how helpful an extended event and few other tools can be to help fixing orphan transactions in a real use case scenario. I often gave training with customers about SQL Server performance and tools, but I noticed how difficult it can be to explain the importance of a tool if you only explain theory without any illustration with a real customer case.
Well, let’s start my own story that began a couple of days ago with an SQL alert to indicate a blocking scenario issue. Looking at our SQL dashboard (below), we were able to confirm quickly we are running into an annoying issue and it would be getting worse over if we do nothing.
