disk plugin: UseBSDName doesn't work on Mac OS X 10.7.3

[blysik]

I wanted to try the new UseBSDName option in 5.2, so I compiled a new version, and deployed to a host. With this config:

LoadPlugin disk
<Plugin "disk">
  UseBSDName true
</Plugin>

I don't get anything at all collected for disks. From the documentation, this should start processing all the disk devices, right/

[blysik]

I recompiled with debugging, and this is all I see:

[2013-01-30 13:47:55] plugin_read_thread: Handling `disk'.
[2013-01-30 13:47:55] plugin_read_thread: Effective interval of the disk plugin is 10.000000000.
[2013-01-30 13:47:55] plugin_read_thread: Next read of the disk plugin at 1359582485.263360999.

Over and over.

Sorry, in my initial post, there should by Plugin disk tags around the UseBSDName true line.

Also forgot to copy the debugging version of disk plugin into place. When I do, I get a little more information:

[2013-01-30 14:17:22] type = disk
[2013-01-30 14:17:22] type = disk, key = UseBSDName, value = true
[2013-01-30 14:17:22] plugin_read_thread: Handling `disk'.

This is a machine running 10.7.3

Hi, sorry for coming back so late.

Can you verify that you in fact have the "BSD subsystem" installed on that Mac? Also, could you post the output of ioreg -n IOMediaBSDClient into a Gist and link to it here?

Thanks and best regards,

I'll play. I don't know what the "BSD subsystem" you are referring to is.

Machine running 10.8

Unassigning myself since I don't have a Mac OS X instance to test.

We also have this same issue with the disk plugin. BSD subsystem is installed (does anyone NOT install it? you have to do a custom install and explicitly leave it out if you don't want it).

I just checked on my Macbook Pro running 10.11 with Collectd 5.5.1.
I get values for 'disk0' with UseBSDName true:

[2016-02-27 18:22:03] write_log values:
localhost.disk-disk0.disk_time.read 4717309090 1456593723
localhost.disk-disk0.disk_time.write 979393052 1456593723

@blysik can you check if this is still an issue for you?

[blysik]

I'm hopeful to roll the latest version of collectd out shortly. I'll report back soon.

[rubenk]

@blysik any luck?

[rubenk]

I'm going to close this. Please open a new issue if this is still an issue in the latest version of Collectd.
