Much of this is like disk, wafl and system statistics before. The
“GetVolumeData” has been renamed to “VolumeUsage” and the
“GetDiskUtil” and “GetSnapUtil” options have been changed, too. 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.

netapp plugin: Refactored reading of disk data.
Instead of obscuring control-flow with generic function pointers, use a
clear and easy to read function hierarchy. All disk-related action now
starts with “cna_query_disk (host)” instead of
“service->handler (host, data, service->data)”.
The “GetDiskPerfData”block has been renamed to “Disks”. All those
blocks start with “Get” and most end with “PerfData”, distracting
from the actual relevant part.
The “Multiplier” option has been replaced by the “Interval” option,
which expects a time in seconds rather than a factor which is multiplied
to the host interval.

The structure is roughly like this: Structs that only hold flags to tell

The "disk_t" type now included flags, too, to indicate valid / invalid
values. The "query_submit_disk_data" function has been changed to honor
those flags.
Various "volume_data" stuff has been renamed to "volume_usage" to make
it more distinguishable from "volume_performance".
Various defines are now also prefixed with "CFG_" to show which flags
are used for configuration and which are used do mark counters valid.
The latter use the "HAVE_" prefix.

functions use the “per_volume_perf_data_t” struct to pass the counters
from one value to the other. The flags have been extended to include
HAVE_* flags. This way we can reliably determine whether an “old”
counter is valid or not.

Moin,
ich wollts ja eigentlich letzte Woche schon geschickt haben, aber hier ists
nun doch noch: Das collectd netapp Plugin. Es ist noch einiges an doppeltem
Code vorhanden, er ist noch nicht schön und der Configurationscode ist noch
nicht in der angemessenen Ausführlichkeit getestet, aber zumindest hier bei
mir funktioniert jetzt alles und ist voll konfiguriertbar.
Kompilieren tut ich das Ganze so:
gcc -g -c -Wall -I include -I /home/ifst/collectd-4.4.2/src netapp.c
gcc -g -o netapp.so -lnetapp -lxml -lpthread -ladt -lssl -lm -shared netapp.o
Mit freundlichen Grüßen

Mmm, why not something like: "static int ps_read_task(pid)"?
This returns the number of task for pid passed as argument.
(AFAIK the function only return the number ot threads), why
we need the ret_num_proc and the ret_num_lwp parameters?
My proposal is attached (code is always cleaner than explanations :P)

Build system: Improve detection of the iptc library.
When checking for the iptc headers and data types, the configure script
added the kernel directory to the CFLAGS. Later, when actually building
the iptables plugin, the CFLAGS were left untouched.
At least on Debian, the “real” kernel headers are not required – the
libc versions in /usr/include/linux are sufficient. The usage of
KERNEL_DIR has therefore been removed from the iptc checks.
In addition, an directory specified by “--with-libiptc=/path” is no
longer added to the global CFLAGS but rather to the iptables specific
CPPFLAGS.
Hopefully this resolved build problems on various platforms.
