I wish to forward certain data from Splunk to a 3rd party as syslog via a HF. I know that newly indexed data will get forwarded to 3rd party system. However, will this setup allow me to forward historical data as well? Basically, my intend is to push 3 months of data from an index to a 3rd party system along with any new data that gets stored in that index.
Document link which you have provided will help you to route new incoming data to 3rd party server. if you want to export historical data from Splunk to 3rd party Syslog server then look at this app https://splunkbase.splunk.com/app/4199/
