Opened: May 30, 2018
Severity: 3-Major

Symptoms

Analytics errors out with a log that says you cannot use custom lookup only along with analytics (/var/log/apm). Even if the Analytics agent is set to disable RST on failure, the agent will send a RST.

Impact

This configuration leads to an Analytics agent with 'RST on Failure' disabled. The BIG-IP Admin cannot make the choice to disable RST on failure for this particular setup (even though it is a misconfiguration).

Conditions

In the per-request policy, Category Lookup agent is set to custom lookup only.

Workaround

You can avoid the RST and error by modifying the configuration to use a standard category lookup before the analytics agent. Using a custom-only 'Category Lookup' immediately followed by 'Response Analytics' is not a valid configuration. In this configuration, Analytics cannot run the way it is supposed to because it does not have the right information. 'Response Analytics' gives the option to choose what to do on error: RST, or continue on, implying that the non-RST option is valid. If the admin chooses to not reset, the system should log the error and continue. In this case, the system actually does send a RST, even though the RST is not what the BIG-IP admin intended to configure.

Fix Information

Disabling RST on failure now works properly in this scenario now. The configuration is still technically incorrect, but now the system takes the correct specified action-upon-error.
