If the Prognosis Audit logs are sent to another server, then the current Audit Log Extractor solution will not have access to any Audit Logs for its Displays.
Prognosis 11.3 is targeted to be able to store the Audit Log on another server &/or save them locally. Adding the feature to 11.3 is subject to change.
A possible solution would be to map the remote server as a drive on the Prognosis Monitoring Node. The Audit Log Extractor could then parse the logs with some minor modifications as long as the logs are stored on the remote server in the same format as if stored locally.
