Subject: Can we use SCSI error trace events to monitor SCSI hardware problems ?
Date: Mon, 23 Dec 2013 11:28:23 +0800	[thread overview]
Message-ID: <1387769303.2695.20.camel@localhost> (raw)

Hello, Hannes

I found you owned a project on github named "md_monitor". It supports MD
array by using mdadm tool. But how about generic SCSI devices ? There is
a "scsi_dispatch_cmd_error" tracepoint in SCSI subsystem, from which we
can get something useful output via sysfs.  We can do more work in
userspace. Now I setup a tracepoint in "scsi_print_result" and trace
scsi cmd result. By reading host status and sense data, I can find out
anything wrong while executing SCSI commands. Does it make sense or it
could be better ?

Thanks,
Junliang Li
