Configuring with DPDK
---------------------
-Note: DPDK 16.04 is the minimum 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: 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
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
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 library:
+ - 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"
