For the last 4 years, I have worked extensively with telemetry on the Dynamics 365 Business Central product. All of this telemetry is stored in Azure LogAnalytics, a big data store that can handle A LOT OF data. In this session I will share my love for this technology, giving you an overview of LogAnalytics and KQL, including KQL vs. SQL. I will show you use cases from Azure Monitor / Azure Application Insights as use cases of Log Analytics. Finally, I will discuss cost (and cost control strategies) of LogAnalytics.
