Hello Greg,

Thank you, but I don't understand. Can you give me an example? Here is the first line of code which I can pair with an upload on primary OSD:

2014-02-12T14:30:08+01:00 stor1 ceph-osd: 2014-02-12 14:30:08.029679 7f8f12425700 20 osd.1 2355 _dispatch 0x1ceb3240 osd_op(client.117465.0:384414 default.4827.2_20140212_7ec1de9c-93e9-11e3-8d77-ebcf0577c360.mp4 [getxattrs,stat] 11.d3793dd5 e2355) v4

Thank you,
Mihaly

This is harder than it sounds, but you can get a broad picture by looking for all the instances of the client request string (I believe it's the one from the incoming message, but I'm not at a computer to check). It outputs all the key points with that tag, and you can look at what's going on in the vicinity of those points for more.

Hello,

I have got strange OSD slowing issue (always on primary OSD): I turned on --debug-log 30/30 to all OSDs, and I would like to track one process (for example write an object) in the log from the beginning to end without annoying other log rows (which are related another processes). Can you put an unique ID which joins a single process to one trackable feed?

Thank you!
