I am using the Barracuda Splunk app for centralized log management and visualization.
For single box level logging the app works very fine.
In case of a HA pair deployment it would be useful to gather logs on a virtual server level.
At the moment the app is not able to handle these kind of syslog messages. (search queries finish with errors)
I had to build my own search queries, dashboards and graphs for HA pairs, but it would be nice to have all Barracuda logs in one place.
