Traffic Router Log files
Hi,
I've been looking for the traffic router log files, access log and
application log.
I've looked under /opt/traffic_router/var/log/ and it's empty. Also, I
don't see anything related under /var/log/
Is there any relevant configuration I should take care of?
Thanks,
Naama

Re: Traffic Router Log files
Posted by Naama Shoresh <na...@qwilt.com>.
Thanks a lot, Jeff!
We've found the source of the problem. We ran over CATALINA_OPTS, instead
of appending to it.
Setting it back solved the looging issues, and now the access log is also
being written.

Re: Traffic Router Log files
Posted by Jeff Elsloo <je...@gmail.com>.
Thanks, this is very helpful. Between what you found, and the output
of `ps` that you provided previously, I think we should take a look at
a couple of things related to Tomcat. I didn't notice this at first,
but you don't seem to have the same command line that we expect to
have, which includes the path to log4j.properties. I'm not 100% sure
why the access log isn't being written, but before we dig in on that,
we need to verify your Tomcat configuration. Before you proceed, roll
back any changes you made under the expanded war's directory structure
(/opt/traffic_router/webapps).
Your command:
/usr/bin/java -Djava.util.logging.config.file=/opt/tomcat/conf/logging.properties
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.net.preferIPv4Stack=true
-Djava.endorsed.dirs=/opt/tomcat/endorsed -classpath
/opt/tomcat/bin/bootstrap.jar -Dcatalina.base=/opt/tomcat
-Dcatalina.home=/opt/tomcat -Djava.io.tmpdir=/opt/tomcat/temp
org.apache.catalina.startup.Bootstrap start
Ours:
/usr/bin/java -Djava.util.logging.config.file=/opt/tomcat/conf/logging.properties
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Xms512m -Xmx8192m
-Dlog4j.configuration=file:///opt/traffic_router/conf/log4j.properties
-server -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions
-XX:InitiatingHeapOccupancyPercent=30
-Djava.endorsed.dirs=/opt/tomcat/endorsed -classpath
/opt/tomcat/bin/bootstrap.jar -Dcatalina.base=/opt/tomcat
-Dcatalina.home=/opt/tomcat -Djava.io.tmpdir=/opt/tomcat/temp
org.apache.catalina.startup.Bootstrap start
You seem to be using either a different init script
(/etc/init.d/tomcat) from what we provide, or you have an environment
file (typically /opt/tomcat/bin/setenv.sh) that is overriding or
unsetting things set in the init script. You also have another flag we
don't use: `-Djava.net.preferIPv4Stack=true`. Specifically, check
`$CATALINA_OPTS` in the init script:
export CATALINA_OPTS="-Xms512m -Xmx8192m
-Dlog4j.configuration=file:///opt/traffic_router/conf/log4j.properties"
You're also missing the minimum and maximum heap size options, which
could affect performance. The GC options in our example are tuning
recommendations based on work that Trevor Ackerman did while
performance testing HTTPS support for Traffic Router, and in our case,
are set via setenv.sh.
If things are still unclear, add "-x" to the shebang at the top of the
init script (#!/bin/sh -x) and /opt/tomcat/bin/startup.sh; this will
allow you to see what the shell is up to as the software starts.

Re: Traffic Router Log files
Posted by Naama Shoresh <na...@qwilt.com>.
Hi Jeff,
I removed the SELinux context from the log directory, as you suggested.
Still no logs.
Nothing in /var/log seem to move when the router accept requests.
When I ran strace, as you suggested, I saw not only that the application
does not attempt to open any file under /opt/traffic_router/var/log, but it
also doesn't read log4j.properties.
I then copied log4j.properties from /opt/traffic_router/conf/ to
/opt/traffic_router/webapps/core/ROOT/WEB-INF/classes/ and restarted
tomcat. After that, two files were created under
/opt/traffic_router/var/log/: access.log & traffic_router.log.
However, the access log is empty, and nothing is written to it even when
requests are accepted and handled. traffic_router.log does not show any
relevant errors.
I ran strace again and found only the following calls wrt access.log:
2630 open("/opt/traffic_router/var/log/access.log",
O_WRONLY|O_CREAT|O_APPEND, 0666) = 83
2630 fstat(83, {st_mode=S_IFREG|0644, st_size=160, ...}) = 0
2635 futex(0x7f3aa40af354, FUTEX_WAIT_BITSET_PRIVATE, 83, {9116,
317686081}, ffffffff <unfinished ...>
Do you have any idea why nothing is written to the access.log?
Also, why isn't log4j.properties read from its original location under
/opt/traffic_router/conf, and what is the correct path to put it in?
Thanks again,
Naama

Re: Traffic Router Log files
Posted by Jeff Elsloo <je...@gmail.com>.
Just to be safe, I would explicitly remove the SELinux context from
the log directory: `setfattr -x security.selinux
/opt/traffic_router/var/log`
What about the other logs under /var/log – anything of note? You could
try starting Tomcat with strace: `strace -f -o /tmp/strace.out
/etc/init.d/tomcat start`, wait for the application to start accepting
requests, then control-c (you might have to kill it forcibly). You
will have a lot of output from strace, but if you grep /tmp/strace.out
for "open" and "opt" you should hopefully see the Java process
attempting to open the log files, and an error message if there's a
problem.
We use the same log4j.properties configuration and everything logs as
expected. I did notice that the header in your log4j.properties is
dated; what version of Traffic Router are you using?

Re: Traffic Router Log files

Thanks, Jeff.
SELinux is disabled, and I see no related errors in /var/log/messages.

Re: Traffic Router Log files
Posted by Jeff Elsloo <je...@gmail.com>.
Hi Naama,
I think SELinux might be rearing itself here. In your `ls` output, a
period follows the permissions, which indicates a file with an SELinux
context (see `info ls`):
drwxr-xr-x. 2 root root 4096 Oct 14 22:15 log
..you will likely have some sort of SELinux related message indicating
that a context problem exists in /var/log/messages (or similar).
Please see this guide for disabling SELinux:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security-Enhanced_Linux/sect-Security-Enhanced_Linux-Enabling_and_Disabling_SELinux-Disabling_SELinux.html
Try that and please let us know if it resolves your issue.

Jeff

Indeed weird.
tomcat is run as a service, by root, which, of course, can write to
/opt/traffic_router/var/log/.
[root@tc3-router ~]# service tomcat status
tomcat (pid 1122) is running...

Re: Traffic Router Log files
Posted by Dave Neuman <ne...@apache.org>.
That’s weird. If it is running it should be logging. Is it somehow possible
that the user running tomcat does not have access to
/opt/traffic_router/var/log or is it possible that
/opt/traffic_router/conf/log4j.properties was changed to not log anything?

Re: Traffic Router Log files
Posted by Naama Shoresh <na...@qwilt.com>.
Hi Dave,
Thanks for your help.
tomcat is running:
# service tomcat status
tomcat (pid 1104) is running...
The traffic router seem to be running also.
It answers dig and routes traffic as expected. It also sends a stats file.
But still, no logs under /opt/traffic_router/var/log/
In the tomcat log, I only see some warnings:
Jan 24, 2017 2:03:24 AM

Re: Traffic Router Log files

Logs for Traffic Router should be under /opt/traffic_router/var/log/ if you
are not seeing any there I would make sure tomcat is started and traffic
router is running. You can do a quick check by using dig, using curl, or by
hitting the API at http://<traffic_router_url>:3333/crs/stats. If you
Traffic Router is failing to start, you will want to check the tomcat logs
at /opt/tomcat/logs and see if there are any errors there.
Thanks,
Dave
