Splunk Universal Forwarder Data Recovery Following a Network Issue

Hi,

Just wondering if anyone has encountered the following issue.

I want to setup a distributed Splunk environment consisting of one indexer and multiple forwarders, let's say 6. The forwarders will be installed on a different network and must pass through a firewall in order to contact the indexer. If, for some reason, the network drops and the forwarders are unable to contact the indexer, what happends in this case?

-Do the forwarders stop sending data immediately?

-Will I lose some data from the files that the forwarders are monitoring?

-Is there a clean and elegant way to synchronize the files being monitored by the forwarders and the events on the indexer?

I am trying to setup Splunk on a production environment and having all of the events produced on the servers is crucial.

Has anyone had a similar issue and found a reliable solution?

Any help would be greatly appreciated!

Thanks!

Splunk operates over TCP, so you don't lose data, although if your network outage lasts a long time you can find it starts chewing through memory. Once the connection restores it will eventually catch up automatically (provided it has the bandwidth).

Is this information taken from the splunk documentation ?
