s/rfc3164/ISO8601/
That's what I get for trying to search from my phone while writing
an email on the train.

Configuration files should be under /etc per FSH

I, personally, like json logs since I'm shipping to logstash. :-)
My one suggestion would be to ensure the timestamps are in
rfc3164.
Yes, those are complex steps, but the rpm/deb packaging should
take care of dependencies and setting up logical defaults.
IMHO, since this is a departure from the way it's been before now,
the config file should enable this new behavior, not disable it,
to avoid breaking existing monitoring installations.

I think that adding all that 'rsyslog' configuration only to see logs is
too much. (I admit it, I don't know how to configure rsyslog at that
level so that may influence my opinion)

Hi All,
Recently new logging framework was introduced [1][2][3] in glusterfs master branch. You could read more about this on doc/logging.txt. In brief, current log target is moved to syslog and user has an option to this new logging at compile time (passing '--disable-syslog' to ./configure or '--without syslog' to rpmbuild) and run time (having a file /var/log/glusterd/logger.conf and restarting gluster services).
As rsyslog is used as syslog server in Fedora and CentOS/RHEL and default configuration of rsyslog does not have any rule
specific to gluster logs, you see all logs are in /var/log/messages in JSON format.
Below is the way to make them neat and clean.
For fedora users:
1. It requires to install rsyslog-mmjsonparse rpm (yum -y install rsyslog-mmjsonparse)
2. Place below configuration under /etc/rsyslog.d/gluster.conf file.
#$RepeatedMsgReduction on
$ModLoad mmjsonparse
*.* :mmjsonparse:
template (name="GlusterLogFile" type="string" string="/var/log/gluster/%app-name%.log")
template (name="GlusterPidLogFile" type="string" string="/var/log/gluster/%app-name%-%procid%.log")
template(name="GLFS_template" type="list") {
property(name="$!mmcount")
constant(value="/")
property(name="syslogfacility-text" caseConversion="upper")
constant(value="/")
property(name="syslogseverity-text" caseConversion="upper")
constant(value=" ")
constant(value="[")
property(name="timereported"
dateFormat="rfc3339")
constant(value="] ")
constant(value="[")
property(name="$!gf_code")
constant(value="] ")
constant(value="[")
property(name="$!gf_message")
constant(value="] ")
property(name="$!msg")
constant(value="\n")
}
if $app-name == 'gluster' or $app-name == 'glusterd' then {
action(type="omfile"
DynaFile="GlusterLogFile"
Template="GLFS_template")
stop
}
if $app-name contains 'gluster' then {
action(type="omfile"
DynaFile="GlusterPidLogFile"
Template="GLFS_template")
stop
}
3. Restart rsyslog (service rsyslog restart)
4. Done. All gluster process specific logs are separated into /var/log/gluster/ directory
Note: Fedora 19 users
There is a bug in rsyslog of fedora 19 [4], so its required to recompile rsyslog source rpm downloaded from fedora repository ('rpmbuild --rebuild rsyslog-7.2.6-1.fc19.src.rpm' works
fine) and use generated rsyslog and rsyslog-mmjsonparse binary rpms
For CentOS/RHEL users:
Current rsyslog available in CentOS/RHEL does not have json support. I have added the support which requires some testing. I will update once done.
TODO:
1. need to add volume:brick specific tag to logging so that those logs can be separated out than pid.
2. enable gfapi to use this logging framework
I would like to get feedback/suggestion about this logging framework
Regards,
Bala
