Why is syslog-ng logging to different logfiles?
This isn’t syslog-ng’s fault, but a side effect of syslog-ng logging to different logfiles than your old syslog daemon. Change your log rotation program’s (for example: logrotate) config files to rotate the new log names/locations or change syslog-ng’s config file to make it log to the same files as your old syslog daemon.
Do you need to use timestamp for syslog-ng?
If syslog-ng was installed from a package for your Linux distribution, log rotation is already configured. You should still take care for any new log destinations you create. An alternative is to use timestamp in log file names, effectively causing log rotation to be performed automatically by syslog-ng.
How to terminate syslog-ng in debug mode?
If that user does not have permission to open a terminal, go to next section. Press CTRL + C to terminate syslog-ng, if it was not terminated by itself. Debug mode generates huge amount of log messages. It’s recommended to redirect the output to a log file. Depending on your system, one of the following methods should work.
Which is the best syslog ng for Linux?
syslog-ng is an open-source log management solution providing enhanced capabilities for collecting, parsing, classifying, and correlating logs across endpoints. This article will focus on installing syslog-ng on a Linux-based system (specifically, Ubuntu 16.04).
Is it possible to reload syslog-ng after chrooting?
The syslog-ng application initializes its configuration before the changing the root (e.g., the local UNIX domain socket ”/dev/log” is opened before chrooting). Note that it is not possible to reload the syslog-ng configuration after chrooting, thus you will need to use restart, or bind-mount the ”/dev” directory into the chroot.
When does syslog-ng send a message to the destination?
When a log statement includes multiple filter statements, syslog-ng sends a message to the destination only if all filters are true for the message. In other words, the filters are connected with the logical AND operator.
Where is the core file when syslog-ng crashes?
When syslog-ng crashes and the ulimit -c resource limit is set to unlimited or a large enough value, the operating system produces a core file upon crash. The location of the core file depends on how syslog-ng was started: Make sure that the syslog-ng process has appropriate write permissions in this directory.
