Verify the correct sys_id of the probe associated with the probe
parameter in the payload of the ECC Queue input record.

## Before you begin

Role required: discovery_admin or admin

## Procedure

1. Record the sys_id of the probe as it appears in the ECC Queue payload.  
   Figure 1. ECC Queue payload sample
2. Navigate to Discovery DefinitionProbes and open the record for the probe you want to inspect.
3. Right-click in the record's header bar.
4. Select Copy sys_id from the context menu.  
   Follow browser instructions to copy the sys_id if browser security measures restrict this function.
5. Compare this value with the sys_id of the probe from the payload.  
   If the sys_id of the probe record does not match the value in the payload, try to determine the cause of the incorrect value.
