Remote Agent Overview
What is a remote agent?
A remote agent is a service that runs in the background on a machine within your environment, and is responsible for generating the snapshots and documentation for the solutions configured within SentryOne Document. It feeds the snapshot and documentation back to SentryOne Document Cloud. This agent service needs to be installed on a machine that has access and permissions to the environments configured to be documented. See the System Requirements article for more details.
Where should a remote agent be installed?
The remote agent may be installed on any on-premises machine that meets the system requirements, including access to all the resources (i.e. a SQL Server) it must connect to in order to create documentation. Keep in mind that since it runs as a Windows service in the background, it can only perform the work while the machine is running. A machine that is shut down overnight will not be able to generate documentation or take snapshots during that time.
How many remote agents are needed?
In general, you should start with a single remote agent. Situations where you may need more than one remote agent include:
- You require numerous or large snapshots and they are taking longer than acceptable to complete with a single agent
- Your network environment is locked down in such a way that not one machine has access to all the resources you are trying to document. In this case, you might need to install a remote agent on Machine1 to access SQLServer1, and a remote agent on Machine2 to access SQLServer2.
What is a remote agent pool?
A remote agent pool is a grouping of remote agents in your SentryOne Document environment. SentryOne Document automatically creates a default system-generated remote agent pool that you can't change. When you register any remote agent, your remote agent goes into the system-generated pool by default. If you have multiple remote agents, and want to control what work they can pick up, you can group them into pools. When a snapshot is requested for a solution item, it allocates that work to any of the available agents within the pool that's associated with the solution item.
For example, you could create remote agent pools with remote agents that document only:
- your production server
- your development server
- SSIS packages

Note: For a more detailed log, you can view the log output for your on premises installation at the following path:C:\Program Files (x86)\SentryOne\SentryOne Document Remote Agent\SentryOne.Document.RemoteAgent.exe.config
Logging is set to record any error by default. If you want your log to record more detailed data, you can change this configuration to debug.
Managing Remote Agent Pools
Manage Remote Agent Pools
Manage your remote agents pools in SentryOne Document. In SentryOne Document, select > Remote Agents Pools to open the Remote Agents Pools management page.
Manage Remote Agent Pools page details
Note: SentryOne Document automatically creates a default system-generated remote agent pool that you can't change. When you register a remote agent, your remote agent goes into that pool by default.
Use the SentryOne Document Remote Agent pool page to create custom pools, and move agents around between them. If you have multiple remote agents, and want to control what work they can pick up, you can group them into pools. When a snapshot is requested for a solution item, it allocates that work to any of the available agents within the pool that is associated with that solution item.
Creating a new pool
Create a new remote agent pool in the Manage Remote Agents pools page by completing the following steps:
- Select + to open the New Remote Agent Pool window.
- Enter a Pool name, and then select Save to create your remote agent pool.
Success: Your remote agent pool is ready to use!

Deleting a Remote Agent Pool
Important: Before deleting a selected remote agent pool, you must reassign all the existing remote agents, solutions, and solution items within the pool to another pool.
Delete a selected remote agent pool from SentryOne Document by completing the following:
1. Reassign any remote agents, solutions, or solution items that are assigned to the pool you want to delete. In this example, we reassign a remote agent to a different pool.
2. Open the Remote Agent Pools page ( > Remote Agent Pools).
3. Select the Delete button for the remote agent pool you want to delete, then select Confirm Delete to complete the process.
Success: The remote agent pool has been deleted from your SentryOne Document environment.
