Azure Monitor is a Microsoft tool for collecting and analyzing metrics from your cloud and on-premises environments. It provides insight on how applications are performing, and identifies issues affecting them and the resources they depend on. Data collected by Azure Monitor fits into one of two types: metrics and logs. Metrics are numerical values that describe some aspect of a system at a particular point in time. Logs contain different kinds of data organized into records, with different sets of properties for each type.
