February 2019 - Log Analytics terminology
After the consolidation of different services under Azure Monitor, we're taking the next step by modifying terminology in our documentation to better describe the Azure Monitor service and its different components.
Log Analytics
Azure Monitor log data is still stored in a Log Analytics workspace and is still collected and analyzed by the same Log Analytics service, but we are changing the termLog Analyticsin many places toAzure Monitor logs. This term better reflects its role in Azure Monitor and provides better consistency withmetrics in Azure Monitor.
The termlog analyticsnow primarily applies to the page in the Azure portal used to write and run queries and analyze log data. It's the functional equivalent ofmetrics explorer, which is the page in the Azure portal used to analyze metric data.
