I've been using logstash since February in order to index data about CDR (Call Detail Record) from our international central (basically a cvs with the data)
So far so good: logstash behaved in a stable way, with no problems.
But since last week I've notice that several lines in some files where not indexed. I've looked in the logstash-plain.log but I see no errors.
How Can I debug this behaviour?
Thank you very much in advance
