I had two .sincedb files at the same time. Deleted but I am still getting a blinking cursor when I issue the following:
HOME_NET/bin/logstash -f first-pipeline.conf
I would agree with you that the sincedb was part of the issue. Also, unless It takes more than a few minutes for logstash to log a apache log the problem still persists. (Imagine the cursor is blink on the next line)
Settings: Default filter workers: 1
Logstash startup completed
I will keep troubleshooting. Let me know if you need any more questions asked about details or others paths to confirm something.
UPDATE: Reading a log file into Logstash - #5 by gruszeckim2
There is more to this issue. I will update as I get more information after deciphering the debugging phase.
