Azure Log Insights-Service Map

07/03/2018

Many are familiar with the Log Insights that were once called the Operations Management Suite.

In this post I will highlight one of the many Log Insights solution plug-ins (called Solutions in the portal) that is Service MAP

NEED

Migrating a Datacenter is not just about taking servers from side to side, it is often necessary to migrate environments by application profile.

The purpose in these cases is to know which servers should be migrated together so as not to have communication problems both between the same application and between the service and the clients.

The problem is often to be able to map this, because few companies have a map of applications that list the servers and services used in each application, mainly Web applications and Databases.

SOLUTION

Log Insights Solution Service Map solves this problem!

It maps all communications that are performed with the servers with the agent installed and mounts a complete map of the usage detailing ports, names, services and allowing drill-down to view the connections and a detail pane for each selected item.

Here are some prints I use to demonstrate the feature:

View the services on one of the servers and details of the selected server. Note that on the left side you can see the server details bar mapped from other Active Solutions in your Log Insigths.

Details of one of the servers that communicates with the host, with details of the communication and the server.

By opening the selected server on the previous screen I can see the details of it, including now the desktops and other servers that also use the selected target.

Viewing the communication details between the target server and the server with SQL Server where we can see the SQL communications for authentication, since the target is my Domain Controller.

Grupo

Here we can see in the concept of groups where the servers that the group includes are mapped and can be used to create the maps of a certain application.

Based on the above graph, I can see that the T110 host has two main VMs that communicate with all clients and between them constantly.

If you are going to create a migration plan for my environment you would already know that they are the two major VMs that need to be activated together in the migration.

USING THE SERVICE MAP

To use the Service Map you obviously must have a Log Analytics account already enabled and include the Solution.

The data collection is not performed by the normal agent of Log Insights, it is necessary to download a specific agent that can be found in the link below:

https://docs.microsoft.com/en-us/azure/monitoring/monitoring-service-map-configure

Soon after installing the Service Map agent you will already be able to view the maps and use groups.

Important: The Service Map only maintains data for a maximum of 1 hour, so it is a portal for immediate viewing as it has no history or analytical reports.
