Hi
Does anyone know how I can disable logging of zoneminder stuff to /var/log/messages? I want logging in separate files instead, this also works, I get all these zm* files in /tmp. But I would like to disable logging to the messages file as I get 100's of entries like these:

Code: Select all

Aug  6 11:57:06 AMD2400 zma_m1[8834]: INF [Pinnacle: 38626000 - Processing at 24.39 fps]
Aug  6 11:57:47 AMD2400 zmc_dvideo0[8830]: INF [Pinnacle: 38627000 - Capturing at 24.39 fps]

And I can't see system problems anymore.
Didnt see the option in ZM web panel...

Good one, would like to do the same.

Well one option is just to use your syslog daemon to filter them out, for syslog-ng an example would be:
filter f_zm { match("^zm.*"); };
destination zm { file("/var/log/zm.log"); };
log { source(src); filter(f_zm); destination(zm); };

I added that to my /etc/syslog file, and did /etc/init.d/syslog restart, but nothing changed...

Doesn't work for me either.
mitch: How exactly has this to be done?
Thanks

As I mentioned my specific example was for the syslog daemon syslog-ng, its config file is generally /etc/syslog-ng/syslog-ng.conf so you most likely have a different syslogger. You would have to look at the man page for the specific format for yours.

I found the right config file and ow-surprise it worked.
Do you know if this also filters other information out or only zoneminder info? Nothing from other programs what contains "zm"?

Got my hopes up too soon...
It does actually log all the zoneminder messages into /var/log/zoneminder.log, but it does at the same time still log them into /var/log/messages. Do I have to add something to the code that it only logs the messages there?

Code: Select all

#
# Filter Zoneminder 
#
filter f_zm { match("^zm.*"); };
destination zm { file("/var/log/zoneminder.log"); };
log { source(src); filter(f_zm); destination(zm); };

So does no one know how I can disable logging to messages file? I got all relevant stuff logged to zoneminder.log, but everything is still in messages too!

I use the following in my rsyslog.conf

Code: Select all

# Save ZoneMinder messages to zm.log
local1.*                                                /var/log/zm/zm.log

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
#*.info;mail.none;authpriv.none;cron.none                /var/log/messages
*.info;local1.!*;local1.warning;mail.none;news.none;authpriv.none;cron.none     /var/log/messages

The first line directs all ZM messages to the zm.log file. The second line (in addition to normal settings) turns off all ZM messages to /var/log/messages, then switches on ZM messages of warning and above. This basically disables info etc. ZM uses the local1 facility so if you want to turn off all messages to the /var/log/messages file just include the local1.!* bit and not the section afterwards.

This is for rsyslog but most logging systems will be similar.

Thaks for this thread, I've now tidies up /var/log/messages but my zm.log gets pretty large (even with rotation). I seems to be getting 1 entry every 2 to 3 seconds, is that right? It seems like an awful lot of detail that also seems to consume CPU and disk resources - is this normal behavior?

top shows me using 22% CPU on my machine (zma and zmc being the main culprits) while the web console only shows load at 0.5%. What am I missing?

High,

the given lines from the previous post

Code: Select all

#
filter f_zm { match("^zm.*"); };
destination zm { file("/var/log/zoneminder.log"); };
log { source(src); filter(f_zm); destination(zm); };

do work, but just generate a new logfile with the zm messages. I had to change the filter for /var/log/messages to prevent zm-messages to be logged there too. My OpenSuSE 11.2 uses the filter f_messages. The corresponding line may look like this:

Code: Select all

#
# All messages except iptables and the facilities news and mail:
#
destination messages { file("/var/log/messages"); };
log { source(src); filter(f_messages); destination(messages); };

I hat to change this line

Code: Select all

filter f_messages   { not facility(news, mail) and not filter(f_iptables) ; };

to

Code: Select all

filter f_messages   { not facility(news, mail) and not filter(f_iptables) and not filter(f_zm); };

For an OpenSuSE distri the syslog-ng.conf file ist located in

/etc/syslog-ng/syslog-ng.conf

Hope this hint helps someone else.

High!

recently I changed from OpenSuSE 11.2 to 11.3. With this change syslog-ng was installed version 3.1.1.

Unfortunatly the filter() changed too. As a result, all zm-messages could be found again in /var/log/messages. Ugly!

I had to read a lot of docs to find out what to change. First I tried the following by changing the filter():

Code: Select all

filter f_zm { message("^zm.*"); };

I tried this, cause I got the message "Starting syslog servicesWARNING: the match() filter without the use of the value() option is deprecated and hinders performance, please update your configuration;" and the manpages mentioned, that message() replaces the older match().

But this was not realy the truth. With the following definition I got success;

Code: Select all

filter f_zm { match('^zm.*' value(MSGHDR)); };

All other lines (see posting above) are still the same.

I hope this helps somebody out
