we are currently testing Graylog.
After the first import, we reset the Graylog server. The logs are then imported from where the import left off. Where is the timestamp stored so that we can reset it and get the imports as they were during the first import?
That’s not happening in graylog. It’s happening on whatever agent etc you are using to send the logs to graylog, beats. Nxlog etc, they are keeping track of what they have already sent in.
There would be a way to clear that, but it depends on the software.
