NOTE: 

• To speed up the resolution process, make sure that the troubleshooting information is gathered before submitting a case.
• Technical Support might request for other data depending on the issue.

First enable debug logging on the client. Modify the client’s policy on your ePO server:

1. Log on to the ePO console.
2. Click Menu, Policy, Policy Catalog.
3. From the Product drop-down list, select McAfee DXL Client.
4. Select an existing policy and edit, or create a new policy.
5. Set Client Log Settings to Enable debug logging.
6. Click Save.
7. Make sure that the policy is assigned to the client.
8. Send an agent wake-up call to the client.
9. Replicate the issue and forward the Minimum Escalation Requirements (MER) file.

When collating the data from the DXL Broker, see KB92053 - Data needed for Data Exchange Layer(Server-side) issues 
              
To view which DXL broker the client is communicating with:

1. Click the McAfee Agent tray icon.
2. Click About.
3. View the McAfee Data Exchange Layer properties.
   The Broker DNS name identifies the name of the Broker to which the client is connected with.

To fully understand an issue, the logs from both sides of the conversation (client and server) is needed. It is recommended that you provide the logs from the DXL Client and the DXL Broker. Also, provide the logs from the Product Server that cover the same time period and show the issue.

2. Minimum Escalation Requirements (MER) Logs

The MER logs from both the client and server is needed if the logging does not fully explain the issue. The MER logs include the following:

• Environmental variables
• Running processes
• Other managed products installed
• Exact version numbers of all McAfee products (For example; ePO, ENS, McAfee agent, DXL).

NOTE: McAfee recommends that the description provided in the raised Service Request is clear and concise for all products. It would help the Technical Support to resolve the issue at the earliest.
