Notes & disambiguation
- Originally introduced as System Center Advisor and rebranded to Azure Operational Insights in 2014 before becoming the cornerstone of Microsoft Operations Management Suite (OMS) in May 2015; at Microsoft Ignite in September 2018, Microsoft consolidated OMS Log Analytics, Application Insights, and Azure Monitor metrics/alerts into a single unified Azure Monitor experience.
- The standalone OMS web portal was retired for the Azure public cloud in early 2019 and for Azure US Government on May 15, 2019, moving all Log Analytics workspace management, Kusto Query Language (KQL) query authoring, dashboards, and alerting into the Azure portal.
- Despite the 2018 consolidation under Azure Monitor, Log Analytics workspaces still use the legacy 'Microsoft.OperationalInsights/workspaces' ARM Resource Provider namespace alongside 'Microsoft.Insights' for metrics, diagnostic settings, and alerts.
