 Posted: Fri Aug 11, 2006 9:57 pm Post subject: High CPU usage by syslog-ng and huge /var/log/messages |
 |
|
I compiled usb-storage verbose messages into my kernel, and they did help unravel my usb problems. But now I have syslog-ng using about 50% CPU, and several gigabytes a week of usb messages.
I would like to keep the option of turning on or off these messages without recompiling the kernel -- I don't need them now, but I might have another USB problem tomorrow.
Is there a way of temporarily turning off these messages? |

Have a look at at the syslog-ng configuration file /etc/syslog-ng/syslog-ng.conf . You might want to change severity for the kernelmessages . On my machine the notation is | Code: | | source kernsrc { file("/proc/kmsg"); }; |
In the log part, you can change the severity for kernel messages or switch them off completely (commenting them out). e.g. | Code: | | #log { source(kernsrc); filter(f_warn); filter(f_kern); destination(kern); }; |
If have still problems, just post your syslog-ng.conf
