Use this documentation with care! It describes
the heavily outdated version 5, which was actively
developed around 2010 and is considered dead by the
rsyslog team for many years now.
This documentation reflects the latest update of the
previously existing (now removed) v5-stable branch.
It describes the 5.10.2 version, which was never
released. As such, it contains some content that
does not apply to any released version.
To obtain the doc that properly matches your installed
v5 version, obtain the doc set from your distro. Each
version of rsyslog contained the version that exactly
matches it.
As general advise, it is strongly suggested to
upgrade to the current version supported by the rsyslog
project. The current version can always be found on
the right-hand side info box on the
rsyslog web site.
Note that there is no rsyslog community support available
for this heavily outdated version. If you need to stick
with it, please ask your distribution for support.
[rsyslog configuration directive overview]
Available Since: 4.3.0
Type: global configuration directive
Default: operating system default
Description:
Set the maximum number of files that the rsyslog process can have open at any given time. Note that this includes open tcp sockets, so this setting is the upper limit for the number of open TCP connections as well. If you expect a large nubmer of concurrent connections, it is suggested that the number is set to the max number connected plus 1000. Please note that each dynafile also requires up to 100 open file handles.
The setting is similar to running “ulimit -n number-of-files”.
Please note that depending on permissions and operating system configuration, the setrlimit() request issued by rsyslog may fail, in which case the previous limit is kept in effect. Rsyslog will emit a warning message in this case.
Sample:
$MaxOpenFiles 2000
Bugs:
For some reason, this settings seems not to work on all platforms. If you experience problems, please let us know so that we can (hopefully) narrow down the issue.
