Hi.

I have the following rsyslog.conf.

[code:1n93z21c]#
http://www.rsyslog.com/doc/v8-stable/tutorials/tls_cert_summary.html

global(maxMessageSize="16k" net.ipprotocol="ipv4-only"
environment="no_proxy=http://10.191.0.100")

#

# queue.spoolDirectory=getenv('RSYS_SPOOL_DIR')
main_queue(
  queue.workerThreads="4"
  queue.dequeueBatchSize="1000"
  queue.highWatermark="500000"    # max no. of events to hold in
memory
  queue.lowWatermark="200000"     # use memory queue again, when it's
back to this level
  queue.spoolDirectory="/var/spool/rsyslog"  # where to write on disk
  queue.fileName="stats_ruleset"
  queue.maxDiskSpace="5g"        # it will stop at this much disk space
  queue.size="5000000"           # or this many messages
  queue.saveOnShutdown="on"      # save memory queue contents to disk
when rsyslog is exiting
)

#module(load="impstats")
#module(load="imuxsock" SysSock.Annotate="on"
SysSock.ParseTrusted="on")
module(load="imtcp" NotifyOnConnectionClose="on" KeepAlive="on")
module(load="lmregexp")


# Include all config files in /etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf[/code:1n93z21c]

I want to set the [b:1n93z21c]queue.spoolDirectory[/b:1n93z21c] via a
environment variable.


[quote:1n93z21c]queue.spoolDirectory=getenv('RSYS_SPOOL_DIR')[/quote:1n93z21c]

I get the following error when I do this.

[quote:1n93z21c]rsyslogd: error during parsing file /etc/rsyslog.conf, on
or before line 17: syntax error on token 'getenv' [v8.25.0 try <!-- m --><a
class="postlink"
href="http://www.rsyslog.com/e/2207">http://www.rsyslog.com/e/2207</a><!--
m --> ][/quote:1n93z21c]

Is it possible to set the config via environment variable?
