Extended Debug Enhancements

This article relates to LoadMaster firmware version 7.2.53.

In LoadMaster firmware version 7.2.53, the Enable Extended Debug option (in System Configuration > Logging Options > System Log Files > Debug Options) has been enhanced. Enabling this option may be needed when performing extensive testing.

Enabling this option can consume more resources and it is possible that some authorization parameters may be exposed. Only enable this option if recommended by Kemp Support.

When extended debugging is enabled, an additional section (called Extended Debug) becomes available in the Virtual Service modify screen (Virtual Services > View/Modify Services > Modify). You can also configure these fields for SubVSs.

There are two fields that you can configure in this section:

  • L7 Debug Level: Set the level of Layer7 debugging for this Virtual Service. Possible values are as follows:

    • No Debug

    • Call Tracing

    • Full Debug

    • Full Debug + HTTP Headers (this is the new value added in 7.2.53)

Setting the L7 Debug Level to Full Debug + HTTP Headers may expose sensitive information.

  • Client to Trace: Specify the client IP address to trace. No other clients are traced.
