I'm using Logstash 6.2.2 to ingest data coming from another system and then to send them to a REST endpoint via the HTTP output plugin.
When I have a large volume to handle (about 1 000 000 events in few minutes) I found out some created files under /tmp
/tmp/puma20190426-1s8d4en and when opening it I found my events written there ..
Is this a side effect ? What are thoses files, and why Logstash creates them ?
Note: I'm using the persistent queue feature configured under
/var/lib/logstash/queue/ , so I think Logstash should write events there and not else where
