How to validate rsyslog filter printk messaging
Issue
- Need to confirm that rsyslog filtering configuration and printk messaging is working appropriately. This is important when using the hung task timeout kernel settings.
- The
task X blocked for more than Y seconds
message is generated at KERN_ERR level, and the stack dump that follows it is generated and KERN_INFO level - The
rsyslog
line in question looks like this:
*.info;mail.none;news.none;authpriv.none;cron.none;local3.none;local3.error /var/log/messages
# cat /proc/sys/kernel/printk
