Any way to filter what gets put in kernel log buffer?
I know this might be a stupid question but here goes:
Is there any way to place filter(s) on what gets logged in the kernel ring buffer? We have some RHEL 5.5 systems that are SAN-connected with a large number of devices zoned. When the server boots it get quite a lot of sdXX messages logged to the kernel ring buffer, so many it rolls over the initial boot messages.
I know how to increase the size of the kernel ring buffer and how to use dmesg to read the increased size. I'm just wondering if there was possibly a way to block these from being logged in the first place.
TIA
