Now, that I managed to run Tvheadend on my unRAID box, it's "spamming" over the syslog with all kind of unnecessary messages (or errors) which I don't care and/or don't want to track.

 

There is no option to run Tvheadend without logging. Is there any way I can prohibit the app to inject lines into syslog on OS level? I was trying to look around on the Internet, but it seems unRAID's syslog facility is some stripped down version, so I am not sure how this could be worked out.

 

Thank you for any help in advance.

It shouldn't be stripped down. It should be the same as the Slackware version. You should also be able to manage this via some syslog.conf changes.

I've already tried to add the following to /etc/syslog.conf

*.*;tvheadend[6368].none                                -/var/log/syslog

 

and restart syslog daemon by

/etc/rc.d/rc.syslog restart

 

with no luck.

 

...and I discovered this comment in /etc/syslog.conf

 tmm - modified so that everything goes to syslog.

 

that's why I thought it is stripped down, although I don't know what "tmm" is, nor if this comment made by Tom for unRAID or comes from somewhere else.

Try it without the process number, ie: tvheadend and not tvheadend.

You might also want to try it with this before any other entries:

 

tvheadend.* -/dev/null

 

Also, 'tmm' means a comment by LimeTech and in this case only applies to the syslog.conf file. Typical Slackware has items going to /var/log/messages and /var/log/syslog.

Thanks for following this up with me.

 

However unfortunatelly I am still not able to sort this out.

I copied the wrong line above with tvheadend including the process number. First I tried without the process number, then I tried with that as well, then I just copied this here by accident. All in all it, not having the process number in their is not stopping tvheadend to log into syslog either.

 

tried

tvheadend.* -/dev/null

but this doesn't help either.

 

Are you sure syslog.conf is getting processed un unRAID?

Also, what do you mean by try "ie: tvheadend and not tvheadend"?

 

 

You cannot without changing this line.

 

# Everything to syslog:

*.*                                                    -/var/log/syslog

 

syslog does not work on program names or applications, it works on general facilities and levels.

syslog-ng does allow you to filter based on program names, but it''s config file is much more involved.

 

It's possible to write to a pipe, then have another program filter the pipe and write the log, but now you have a co-process in the middle.

 

If you an find the facility and level of the application you can set syslog to ignore it, but then you may miss other messages.

 

Here;'s an example from a RHEL system.

 

# Don't log private authentication messages!

*.info;mail.none;news.none;authpriv.none;cron.none      /var/log/messages

 

According to this code it uses the LOG_DAEMON facility.

if you could recompile the source to use the log_local1 facility.

127

  int logfacility = LOG_DAEMON;

127

  int logfacility = LOG_LOCAL1;

 

Then it would be easy to exclude all messages with.

*.*;local1.none      /var/log/messages

 

but with

*.*,daemon.none  /var/log/messages you may loose some important messages.

WOW, WeeboTech! Many thanks for taking the time to even look in the code.

 

...and your suggested solution works perfectly! Thank you again!

Which way did you go?

 

Recompiled with LOG_LOCAL1 or

 

daemon.none in the /etc/syslog.conf file?

Recompiled with LOG_LOCAL1 and the syslog.conf configured like this:

 

# /etc/syslog.conf
# For info about the format of this file, see "man syslog.conf"
# and /usr/doc/sysklogd/README.linux.  Note the '-' prefixing some
# of these entries;  this omits syncing the file after every logging.
# In the event of a crash, some log information might be lost, so
# if this is a concern to you then you might want to remove the '-'.
# Be advised this will cause a performation loss if you're using
# programs that do heavy logging.

# tmm - modified so that everything goes to syslog.

# Uncomment this to see kernel messages on the console.
#kern.*                                                 /dev/console

*.debug;local1.none                                     -/var/log/syslog

# Emergency level messages go to all users:
*.emerg                                                 *

 

Thank you again!

Hi WeeboTech,

 

that solution works perfectly for a while, but then all of a sudden Tvheadend starts logging in the name of 'nss_wins'. I couldn't find out what is the trigger of that.

 

I tried to do some search on this and found some forum posts about this issue/bug, but couldn't figure out any solution to my case.

 

Did you experienced anything like that or do you know any potential solution for that?

 

Thank you in advance!
