Recently I had to rebuild our Splunk server. Luckily we had the config files so was able to get everything back up and running quickly. However, now all my servers have begun forwarding the logs in as expected, but I am missing everything prior to the system going down. Is there a simple way to centrally tell all my forwarders to resend all the logs?
I assume the Splunk server you erbuilt was an Indexer and now you want all data from log files which were earlier indexed prior to the issue. For that please remove everything from splunkforwarder/var/lib/splunk/fishbucket in the Splunk forwarder and it should restart monitoring as new and resend everything
