I do have a question about the fsync option as well. Does this option tell syslog-ng to flush() after every write, or after all lines have been written (like from the flush_lines or flush_timeout() options)? If it flushes after every write, would it be possible to get an option to flush only once all the messages in the batch have been written?
With the patch Bazsi posted, fsync(yes) will trigger an fsync after every write, assuming a file() destination (tested & verified, I'll apply it to 3.3 git in a couple of minutes). However, as far as I see, writes are done in batches, whenever flush_lines() or flush_timeout() triggers a batch, so fsync(yes) will mean that syslog-ng will fsync after each flush-lines() number of lines, as that is how often it does the write. -- Configure bugmail: https://bugzilla.balabit.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
