-DPDK statistics plugin
-^^^^^^^^^^^^^^^^^^^^^^
+DPDK plugins

Repo: https://github.com/collectd/collectd
Branch: master
-Dependencies: DPDK (http://dpdk.org/) Min_Version: 16.04
+Dependencies: DPDK (http://dpdk.org/)
+
+.. note:: DPDK statistics plugin requires DPDK version 16.04 or later
To build and install DPDK to /usr please see:
https://github.com/collectd/collectd/blob/master/docs/BUILD.dpdkstat.md
$ make
$ sudo make install
+.. note:: If DPDK was installed in a non standard location you will need to
+ specify paths to the header files and libraries using *LIBDPDK_CPPFLAGS* and
+ *LIBDPDK_LDFLAGS*. You will also need to add the DPDK library symbols to the
+ shared library path using *ldconfig*. Note that this update to the shared
+ library path is not persistant (i.e. it will not survive a reboot).
+
+Example of specifying custom paths to DPDK headers and libraries:
+
+.. code:: bash
+
+ $ ./configure LIBDPDK_CPPFLAGS="path to DPDK header files" LIBDPDK_LDFLAGS="path to DPDK libraries"
This will install collectd to /opt/collectd
The collectd configuration file can be found at /opt/collectd/etc
+
To configure the dpdkstats plugin you need to modify the configuration file to
include:
PortName "interface2"
</Plugin>
-For more information on the plugin parameters, please see:
-https://github.com/collectd/collectd/blob/master/src/collectd.conf.pod
-
-.. note:: If you are not building and installing DPDK system-wide
- you will need to specify the specific paths to the header files and libraries
- using LIBDPDK_CPPFLAGS and LIBDPDK_LDFLAGS. You will also need to add the DPDK
- library symbols to the shared library path using ldconfig. Note that this
- update to the shared library path is not persistent (i.e. it will not survive a
- reboot).
-
-.. note:: Plugin initialization time depends on read interval. It requires
- 5 read cycles to set up internal buffers and states. During that time
- no statistics are submitted. Also if plugin is running and the number of DPDK
- ports is increased, internal buffers are resized. That requires 3 read cycles
- and no port statistics are submitted in that time.
-
-DPDK events plugin
-^^^^^^^^^^^^^^^^^^^^^^
-Repo: https://github.com/collectd/collectd
-
-Branch: master
-
-Dependencies: DPDK (http://dpdk.org/)
-To build and install DPDK to /usr please see:
-https://github.com/collectd/collectd/blob/master/docs/BUILD.dpdkstat.md

-Building and installing collectd:
-
-.. code:: bash

- $ git clone https://github.com/collectd/collectd.git
- $ cd collectd
- $ ./build.sh
- $ ./configure --enable-syslog --enable-logfile --enable-debug
- $ make
- $ sudo make install
-
-This will install collectd to /opt/collectd
-The collectd configuration file can be found at /opt/collectd/etc
To configure the dpdkevents plugin you need to modify the configuration file to
include:
</Event>
</Plugin>
+.. note:: Currently, the DPDK library doesn’t support API to de-initialize
+ the DPDK resources allocated on the initialization. It means, the collectd
+ plugin will not be able to release the allocated DPDK resources
+ (locks/memory/pci bindings etc.) correctly on collectd shutdown or reinitialize
+ the DPDK library if primary DPDK process is restarted. The only way to release
+ those resources is to terminate the process itself. For this reason, the plugin
+ forks off a separate collectd process. This child process becomes a secondary
+ DPDK process which can be run on specific CPU cores configured by user through
+ collectd configuration file (“Coremask” EAL configuration option, the
+ hexadecimal bitmask of the cores to run on).
+
For more information on the plugin parameters, please see:
https://github.com/collectd/collectd/blob/master/src/collectd.conf.pod

+
+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.
+
+To disable ASLR:
.. code:: bash
- $ ./configure LIBDPDK_CPPFLAGS="path to DPDK header files" LIBDPDK_LDFLAGS="path to DPDK libraries"
+ $ sudo echo 0 > /proc/sys/kernel/randomize_va_space
+
+To fully enable ASLR:
+
+.. code:: bash
+
+ $ sudo echo 2 > /proc/sys/kernel/randomize_va_space
+
+.. warning:: Disabling Address-Space Layout Randomization (ASLR) may have security
+ implications. It is recommended to be disabled only when absolutely necessary,
+ and only when all implications of this change have been understood.
+
+For more information on multi-process support, please see:
+http://dpdk.org/doc/guides/prog_guide/multi_proc_support.html
+
+**DPDK stats plugin limitations:**
+
+1. The DPDK primary process application should use the same version of DPDK
+ that collectd DPDK plugin is using;
+
+2. L2 statistics are only supported;
+
+3. The plugin has been tested on Intel NIC’s only.
+
+**DPDK stats known issues:**
+
+* DPDK port visibility
+
+ When network port controlled by Linux is bound to DPDK driver, the port
+ will not be available in the OS. It affects the SNMP write plugin as those
+ ports will not be present in standard IF-MIB. Thus addition work is
+ required to be done to support DPDK ports and statistics.
