[Ocfs2-devel] Uitlity for adjusting debug_[level|context]
After working on ocfs2 for a little while now, I find myself still
having to look at ocfs.h every time I want to adjust the log level
and/or context.
I started getting tired of doing this so I wrote an embarrising not
so little utility for adjusting the log level and context for ocfs.
Just in case someone else finds this useful, I attached the source
file to this email.
Here is the kind of stuff it can do...
[root@penguin oracle]# ocfslogctl
Log Level: ERROR TRACE ENTRY EXIT TIMING STACK PRINTK MALLOC
Log Context: INODE
[root@penguin oracle]# ocfslogctl --help
Usage: ocfslogctl [OPTION...]
Control OCFS Log Level
--clear-all Clear all levels and contexts
--show Print the current log level and context
Log level options
--entry Turn on entry level messages
--error Turn on error level messages
--exit Turn on exit level messages
--malloc Turn on malloc level messages
--printk Turn on printk level messages
--set-all-levels Turn on messages for all levels
--stack Turn on stack level messages
--timing Turn on timing level messages
--trace Turn on trace level messages
Log context options
--alloc Enable messages from alloc.c
--bitmap Enable messages from bitmap.c
--dcache Enable messages from dcache.c
--dir Enable messages from dir.c
--dlm Enable messages from dlm.c
--extmap Enable messages from extmap.c
--file Enable messages from file.c
--hash Enable messages from hash.c
--heartbeat Enable messages from heartbeat.c
--inode Enable messages from inode.c
--io Enable messages from io.c
--ioctl Enable messages from ioctl.c
--journal Enable messages from journal.c
--namei Enable messages from namei.c
--nm Enable messges from nm.c
--oin Enable messages from oin.c
--osb Enable messages from osb.c
--proc Enable messages from proc.c
--sem Enable messages from sem.c
--set-all-contexts Enable messages from all contexts
--super Enable messages from super.c
--symlink Enable messages from symlink.c
--sysfile Enable messages from sysfile.c
--util Enable message from util.c
--volcfg Enable messages from volcfg.c
--vote Enable messages from vote.c
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version

[Ocfs2-devel] Uitlity for adjusting debug_[level|context]
Cool. Should come handy. I am not saying you should, because I know how messy this request could be, but it would be ideal if somehow this could be merged with debugocfs.
