If you’re currently using Azure Log Analytics to monitor your environments for availability and performance, we’re rolling out new enhancements and changes for Log Analytics that you should be aware of. Including the new and improved query language, so that you can take appropriate action, if necessary. To take advantage of these enhancements, you’ll need to upgrade your workspaces. The upgrade is currently available in these regions: WCUS, SEAU, SEA, WEU, EJP, SUK, CID and CCAN.
The upgrade process converts all saved searches, alerts, and views to the new query language. About 50 percent of all Azure Log Analytics workspaces have been upgraded by now, and thousands of customers are enjoying the simple yet powerful query language.
