Redirecting user space console messages
Hi,
I'm working on a third party provided embedded hardware(mips). It has a preloaded linux kernel and CFE boot loader. My program needs to collect the console/stdout messages from all the running programs and send to a server. (Somewhat similar to netconsole - but netconsole collects only kernel messages.) Linux bootup options "console=<device>" will help us to add one more console device. But I don't have flexibility to change CFE or rebuild kernel with my own driver. Fortunately, this linux build supports loadable modules. Can I redirect the console output to a loadable module? If so, what are the steps to do it? (My idea is to create a tty-console like device, which loops back the messages to userspace.) PS: Pls let me know, if the system-wide "stdout" redirection is possible by a user land process - that is my first preference. Thanks in advance. Vinod |
If your system has the syslogd daemon running then you might look at that:
$man 8 syslogd User programs can write to the system log files by using the logger command from a script: $man 1 logger or from calling the syslog function from a program: $man 3 syslog |
