DiagnosticSource Execution for Resources

Last updated - 08 December, 2025

LogicMonitor enables you to run user created and LogicMonitor supported out-of-the-box DiagnosticSource modules to fetch diagnostic data to help troubleshoot issues directly from a Resource. You can run multiple DiagnosticSources at the same time across one or more resources, but the same module cannot be run in parallel on a single resource.

LogicMonitor supports the following execution status for a DiagnosticSource module:

Execution Status	Indicates
Not started	The DiagnosticSource module is not yet run.
In Progress	The DiagnosticSource module is currently running.
Success	The DiagnosticSource module is run successfully and has collected relevant data.
Invalid Request	LogicMonitor server received an invalid JSON request.
Reject	LogicMonitor Collector could not handle the incoming request from the server.
Exception	The DiagnosticSource module failed to run due to an error in Collector.
Timeout	Timeout occurs when a script fails to execute due to reasons such as the resource is dead, Collector is down, and so on.

After running the DiagnosticSource, you can view the results generated by the script. This helps identify root cause of the issue you created the DiagnosticSource for. You can view the history of DiagnosticSource module run on a resource. The history provides details of the issues and the diagnosis performed to identify the root cause. You can view the execution history of a resource for a specific time range. 

Requirements for Executing DiagnosticSource

To run a DiagnosticSource module, you need the following:

• The Security settings configured by enabling the Allow Execution of Diagnostic Sources switch to execute DiagnosticSources
  For more information, see Security Settings.
• A LogicMonitor user with Diagnostic Source permissions for the resource group in the Resources permission set
  For more information, see Resources Role Permissions.
• EA Collector 38.400 or later installed

• DiagnosticSource modules in My Module Toolbox and applied to the resources
  For more information, see Configuring DiagnosticSource.
• Resources including cloud resources monitored by local Collectors
  For more information, see Enabling Cloud Monitoring using Local Collector.
