Plugin schedules get mixed

Elastic Stack Logstash
1

I have schedule parameters for cron jobs in the input configurations of http_poller and jdbc plugins:

  • http_poller runs at the mark of the hour, i.e. schedule => { cron => "0 * * * *"}
  • jdbc runs every 2 minutes, i.e. schedule => "*/2 * * * *"

I run everything on the same pipeline.

What I observe, is that logstash triggers the http_poller at much shorter and inconsistent intervals, at 2, 3 or 5 minutes instead of once every hour.

I managed to get it working at some point and wonder whether a combination of systemctl restart logstash.service and the plugins being busy causing past values for cron jobs to be stack into the system.

My bad, figured out I had a test.conf in the /etc/logstash/conf.d folder which got loaded into logstash once I restarted it and was responsible for this seemingly weird behavior.
