TMM core while adding logging action to APM SWG.
TMM core. Traffic disrupted while tmm restarts.
-- Use of an application lookup perflow variable (perflow.application_lookup.result.*) in an SWG per-request Logging Agent. -- No Application Lookup Agent found prior in the chain. For example - The following example will crash: start : logging : allow - The following will succeed: start : application lookup : logging : allow
There are two possible workarounds: -- Remove the applicable perflow variables from the logging agent. -- Add an application lookup before trying to log application lookup perflow variables.
