+Configuring with DPDK
+---------------------
+
+Note: DPDK 16.04 is the minimum version and currently supported version of DPDK
+required for the dpdkstat plugin. This is to allow the plugin to take advantage
+of functions added to detect if the DPDK primary process is alive.
+
+Note: For Ubuntu, GCC 4.9 is the minimum version required to build collectd
+with DPDK. Ubuntu 14.04, for example, has GCC 4.8 by default and will require
+an upgrade:
+ $ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
+ $ sudo apt-get update
+ $ sudo apt-get install gcc-4.9
+Alternatively, if you know that the platform that you wish to run collectd
+on supports the SSSE3 instruction set, you can run make as follows:
+ $ make -j CFLAGS+='-mssse3'
+
+Build DPDK for use with collectd:
+ To compile DPDK for use with collectd dpdkstat start by:
+ - Clone DPDK:
+ $ git clone git://dpdk.org/dpdk
+ - Checkout the system requirements at
+ http://dpdk.org/doc/guides/linux_gsg/sys_reqs.html and make sure you have
+ the required tools and hugepage setup as specified there.
+ NOTE: It's recommended to use the 1GB hugepage setup for best performance,
+ please follow the instruction for "Reserving Hugepages for DPDK Use"
+ in the link above.
+ However if you plan on configuring 2MB hugepages on the fly please ensure
+ to add appropriate commands to reserve hugepages in a system startup script
+ if collectd is booted at system startup time. These commands include:
+ mkdir -p /mnt/huge
+ mount -t hugetlbfs nodev /mnt/huge
+ echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
+ - To configure the DPDK build for the combined shared library modify
+ config/common_base in your DPDK as follows
+ #
+ # Compile to share library
+ #
+ -CONFIG_RTE_BUILD_SHARED_LIB=n
+ +CONFIG_RTE_BUILD_SHARED_LIB=y
+ - Prepare the configuration for the appropriate target as specified at:
+ http://dpdk.org/doc/guides/linux_gsg/build_dpdk.html.
+ For example:
+ $ make config T=x86_64-native-linuxapp-gcc
+ - Build the target:
+ $ make
+ - Install DPDK to /usr
+ $ sudo make install prefix=/usr
+ NOTE 1: You must run make install as the configuration of collectd with
+ DPDK expects DPDK to be installed somewhere.
+ NOTE 2: If you don't specify a prefix then DPDK will be installed in /usr/local/
+ NOTE 3: If you are not root then use sudo to make install DPDK to the appropriate
+ location.
+ - Check that the DPDK library has been installed in /usr/lib or /lib
+ $ ls /usr/lib | grep dpdk
+ - Bind the interfaces to use with dpdkstat to DPDK:
+ DPDK devices can be setup with either the VFIO (for DPDK 1.7+) or UIO modules.
+ Note: UIO requires inserting an out of tree driver igb_uio.ko that is available
+ in DPDK.
+ UIO Setup:
+ - Insert uio.ko:
+ $ sudo modprobe uio
+ - Insert igb_uio.ko:
+ $ sudo insmod $DPDK_BUILD/kmod/igb_uio.ko
+ - Bind network device to igb_uio:
+ $ sudo $DPDK_DIR/tools/dpdk_nic_bind.py --bind=igb_uio eth1
+ VFIO Setup:
+ - VFIO needs to be supported in the kernel and the BIOS. More information can be found
+ @ http://dpdk.org/doc/guides/linux_gsg/build_dpdk.html.
+ - Insert the `vfio-pci.ko' module: modprobe vfio-pci
+ - Set the correct permissions for the vfio device:
+ $ sudo /usr/bin/chmod a+x /dev/vfio
+ $ sudo /usr/bin/chmod 0666 /dev/vfio/*
+ - Bind the network device to vfio-pci:
+ $ sudo $DPDK_DIR/tools/dpdk_nic_bind.py --bind=vfio-pci eth1
+ NOTE: Please ensure to add appropriate commands to bind the network
+ interfaces to DPDK in a system startup script if collectd is
+ booted at system startup time.
+ - Run ldconfig to update the shared library cache.
+
+ Build static DPDK library for use with collectd:
+ - To configure DPDK to build the combined static library libdpdk.a
+ ensure that CONFIG_RTE_BUILD_SHARED_LIB is set to n in
+ config/common_base in your DPDK as follows:
+ #
+ # Compile to share library
+ #
+ CONFIG_RTE_BUILD_SHARED_LIB=n
+ - Prepare the configuration for the appropriate target as specified at:
+ http://dpdk.org/doc/guides/linux_gsg/build_dpdk.html.
+ For example:
+ $ make config T=x86_64-native-linuxapp-gcc
+ - Build the target using -fPIC:
+ $ make EXTRA_CFLAGS=-fPIC -j
+ - Install DPDK to /usr
+ $ sudo make install prefix=/usr
+
+Configure collectd with DPDK:
+NOTE: The Address-Space Layout Randomization (ASLR) security feature in Linux should
+ be disabled, in order for the same hugepage memory mappings to be present in all
+ DPDK multi-process applications. Note that this has security implications.
+ To disable ASLR:
+ $ echo 0 > /proc/sys/kernel/randomize_va_space
+ To fully enable ASLR:
+ $ echo 2 > /proc/sys/kernel/randomize_va_space
+ See http://dpdk.org/doc/guides/prog_guide/multi_proc_support.html
+
+ - Generate the build script as specified below. (i.e. run `build.sh').
+ - Configure collectd with the DPDK shared library:
+ ./configure --with-libdpdk=/usr
+ NOTE: To configure collectd with the DPDK static library:
+ ./configure --with-libdpdk=/usr CFLAGS=" -lpthread -Wl,--whole-archive
+ -Wl,-ldpdk -Wl,-lm -Wl,-lrt -Wl,-lpcap -Wl,-ldl -Wl,--no-whole-archive"
+
+ Libraries:
+ ...
+ libdpdk . . . . . . . . yes
+
+ Modules:
+ ...
+ dpdkstat . . . . . . .yes
+
+
+ - Make sure that dpdk and dpdkstat are enabled in the configuration log:
+
+ - Build collectd:
+ $ make -j && make -j install.
+ NOTE: As mentioned above, if you are building on Ubuntu 14.04 with GCC <= 4.8.X,
+ you need to use:
+ $ make -j CFLAGS+='-mssse3' && make -j install
+
+Usage of dpdkstat:
+ - The same PCI device configuration should be passed to the primary process
+ as the secondary process uses the same port indexes as the primary.
+ NOTE: A blacklist/whitelist of NICs isn't supported yet.

-Wishlist:
-* Port nfs module to solaris
-* Port tape module to Linux
-* Port the apple_sensors plugin to Linux/PPC.
-* Maybe look into porting the serial module
-* Build Darwin package
-* Maybe let the network plugin configure whether or not notifications should be

-* Maybe find a way for processes connected to the unixsock plugin to receive
- notifications, too.

+=item B<RegisterLegacyFlush> I<true|false>
+
+The C<Perl plugin> used to register one flush callback (called B<"perl">) and
+call all Perl-based flush handlers when this callback was called. Newer versions
+of the plugin wrap the Perl flush handlers and register them directly with the
+daemon I<in addition> to the legacy B<"perl"> callback. This allows to call
+specific Perl flush handlers, but has the downside that flushing I<all> plugins
+now calls the Perl flush handlers twice (once directly and once via the legacy
+callback). Unfortunately, removing the B<"perl"> callback would break backwards
+compatibility.
+
+This option allows you to disable the legacy B<"perl"> flush callback if you care
+about the double call and don't call the B<"perl"> callback in your setup.
