Hello, I have a Rails application that produces quite a bit of log output - about 500MB per day, maybe 3-4 million lines. Currently this is going into a normal file with daily rotation.
I tried dumping this into journald via STDOUT so that I could see everything in one place. On a standard Google Cloud Platform instance, this used about 10% extra CPU. I was willing to live with that, but more of a problem was the rapid increase in storage used for the log. It was growing at about 10x the rate as a flat file for the 2 hours I ran the experiment. That is, after 2 hours, the usage reported by 'sudo journalctl --disk-usage' was over 400MB, which is not much less than I would normally see for an entire day's worth of logging. I am wondering if this is to be expected due to journald's extra functionality and complexity, or does this seem incorrect? I'm using systemd 229 on Ubuntu 16.04. Thank you, Bill Lipa _______________________________________________ systemd-devel mailing list email@example.com https://lists.freedesktop.org/mailman/listinfo/systemd-devel
