# Agent based dependency analysis using Azure monitor agent (AMA)

-
[Azure Monitor Agent (AMA)](/azure/azure-monitor/agents/azure-monitor-agent-overview) replaces the Log Analytics agent, also known as Microsoft Monitor Agent (MMA) and OMS, for Windows and Linux machines, in Azure and non-Azure environments, on-premises and other clouds.

Dependency analysis helps you to identify and understand dependencies across servers that you want to assess and migrate to Azure. We currently perform agent-based dependency analysis by downloading the [MMA agent and associating a Log Analytics workspace](concepts-dependency-visualization.md) with the Azure Migrate project.

1. To deploy the AMA agent, it's recommended to first clean up the existing Service Map to avoid duplicates. [Learn more](/azure/azure-monitor/vm/vminsights-migrate-from-service-map#remove-the-service-map-solution-from-the-workspace).

1. Download and run the script on the host machine as detailed in [Installation options](/azure/azure-monitor/agents/azure-monitor-agent-manage?tabs=azure-portal#installation-options). To get the AMA and the Dependency Agent deployed on the guest machine, create the [Data collection rule (DCR)](/azure/azure-monitor/agents/azure-monitor-agent-data-collection) that maps to the Log analytics workspace ID.

In the transition scenario, the Log analytics workspace would be the same as the one that was configured for Service Map agent. DCR allows you to enable the collection of Processes and Dependencies. By default, it's disabled.
