ceph admin command: debuggging

ceph admin command: debuggging

[Andreas Bluemle]

Hi,

maybe this is the wrong list - but I am looking for
logging support for the /usr/bin/ceph adminstration
comamand.

This is build from the same source as the ceph daemons are.

For the daemons, logging is controlled for the different
comoponents of a daemon on behalf of configuration file
directives (e.g. "debug ms" for the message I/O).

Can this be applied to the /usr/bin/ceph command, too?
And where would the log file go?


Thanks for any help

Andreas Bluemle

There are a number of subsystems that the clients use, so a number of 
knobs that matter.  The "logging/authentication name" (the type.id 
name), by default, is 'client.admin'.  Some of the relevant logging 
knobs are ms/monc; of course there are usually effects caused by the 
daemons too, so the mon/osd logs will contain things triggered by the 
client.

What sort of things are you looking for specifically?

You are probably looking for:

 --log-to-stderr     (make log output go to stderr)
 --log-file <filename>

and you can make some noise with

 --debug-ms 1
 --debug-monc 10

(for example)

Thanks; I'll give that a try.
