A temporary file name is used when creating the manpages. So far, a static

suffix (PID) is used to fix that.

I attach a patch for collectd-4.8.0 adding a new feature which read IO
data for a process using /proc/<pid>/io (only works on linux > 2.6.20),
it's very usefull to monitoring disk throughput and what process is
related with high disk IO. I'm using this patchs for days in some
database environments with good results, but I think that is not enough
stable yet (more testing is required). The patch read from
/proc/<pid>/io (where available) the data for syscr and syscw (read and
write operations) and rchar and wchar (read and write bytes).

unixsock plugin: Fix a (well hidden) race condition.
Within the client handling thread, fdopen is called twice on the file
descriptor passed to the thread. Later those file handles are closed like:
fclose (fhin);
fclose (fhout);
This is a race condition, because the first call to fclose will close the file
descriptor. The second call to fclose will try the same. Usually, it would fail
silently and all is well. On a busy machine, however, another thread may just
have opened a file or accepted a socket. In that case an arbitrary file
descriptor is closed. If the file descriptor is opened yet again fast enough,
data may even end up in a totally wrong location.
As a work-around the file descriptor is not dup'ed so each fdopen operates on
its own file descriptor. As an alternative the "r+" mode and a single file
handle may be suitable, too.
Many thanks to Sven Trenkel for pointing me into the right directioin :)

Much of this is like disk, wafl and system statistics before. The

configuration now looks like this:
<VolumeUsage>
Capacity "vol0"
Capacity "vol1"
IgnoreSelectedCapacity false
Snapshot "vol1"
Snapshot "vol3"
IgnoreSelectedSnapshot false
</VolumeUsage>
The code now uses to "ignore lists" to check whether capacity and/or
snapshot information should be collected for a volume. This means the
order in which volumes are listed no longer matters and than you can
use such advanced options as selecting volumes via regular expressions.

from the actual relevant part.
The “Multiplier” option has been replaced by the “Interval” option,

to the host interval.
