Hi,
I modified a Cassandra application to write to a file and use imfile in
rsyslog to avoid the multiline logs headache.
I am running rsyslogd 8.1.6 on both client and server. The rsyslog client
is configured with this imfile:
# Cassandra log
input(type="imfile"
File="/var/log/cassandra/system.log"
Tag="cassandra"
StateFile="stat-localring93-1"
readMode="2"
Severity="info"
Facility="local2")
Using a template for a dynamic file
# Templates for logging remotely
template(name="GroupApp" type="string"
string="<%PRI%>%TIMESTAMP:::date-rfc3339% %HOSTNAME%
%syslogtag%testingdirectory:%msg%\n"
)
if $syslogfacility-text == 'local0' or $syslogfacility-text == 'local1' or
$syslogfacility-text == 'local2' then {
action(type="omrelp" target="my_rsyslog_server" port="XXX"
template="GroupApp"
This template is used for many applications and it works.
I am tunning cassandra permissions but I am testing it with the following
persmissions:
-rw-r--r-- 1 cassandra cassandra 68819 Jul 8 11:25 system.log
I have launched the rsyslog in debug mode and found lines like the ones
below. Don't understand what is wrong here....
Thanks a lot,
Xavi
