+Extended Statistics API
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The extended statistics API allows each individual PMD to expose a unique set
+of statistics. The client of the API provides an array of
+``struct rte_eth_xstats`` type. Each ``struct rte_eth_xstats`` contains a
+string and value pair. The amount of xstats exposed, and position of the
+statistic in the array must remain constant during runtime.
+
+A naming scheme exists for the strings exposed to clients of the API. This is
+to allow scraping of the API for statistics of interest. The naming scheme uses
+strings split by a single underscore ``_``. The scheme is as follows:
+
+* direction
+* detail 1
+* detail 2
+* detail n
+* unit
+
+Examples of common statistics xstats strings, formatted to comply to the scheme
+proposed above:
+
+* ``rx_bytes``
+* ``rx_crc_errors``
+* ``tx_multicast_packets``
+
+The scheme, although quite simple, allows flexibility in presenting and reading
+information from the statistic strings. The following example illustrates the
+naming scheme:``rx_packets``. In this example, the string is split into two
+components. The first component ``rx`` indicates that the statistic is
+associated with the receive side of the NIC. The second component ``packets``
+indicates that the unit of measure is packets.
+
+A more complicated example: ``tx_size_128_to_255_packets``. In this example,
+``tx`` indicates transmission, ``size`` is the first detail, ``128`` etc are
+more details, and ``packets`` indicates that this is a packet counter.
+
+Some additions in the metadata scheme are as follows:
+
+* If the first part does not match ``rx`` or ``tx``, the statistic does not
+ have an affinity with either recieve of transmit.
+
+* If the first letter of the second part is ``q`` and this ``q`` is followed
+ by a number, this statistic is part of a specific queue.
+
+An example where queue numbers are used is as follows: ``tx_q7_bytes`` which
+indicates this statistic applies to queue number 7, and represents the number
+of transmitted bytes on that queue.

[Harry van Haaren]

Update the strings used for presenting stats to adhere
to the scheme previously presented. Updated xstats_get()
function to handle Q information only if xstats() is not
implemented in the PMD, providing the PMD with the needed
flexibility to expose its extended Q stats.

Subject: [PATCH v5 00/10] Port XStats

Series-acked-by: Maryam Tahhan <***@intel.com>

Same code as previous v4, same Ack. Will include in commit message in future.
-Harry

[Thomas Monjalon]

Subject: [PATCH v5 00/10] Port XStats

Applied with some typo fixes, thanks

I'm still not sure about the queue stats handling but it can be fixed
later if more people disagree with your choice.

[Harry van Haaren]

Update the strings used for presenting stats to adhere
to the scheme previously presented. Updated xstats_get()
function to handle Q information only if xstats() is not
implemented in the PMD, providing the PMD with the needed
flexibility to expose its extended Q stats.

Each PMD exposes its own queue stats so it has the flexibility of presenting them exactly has the hardware counts, in a human-readable order.

If the generic xstats were used, testpmd> xstats output would split a single queue's xstats to two places in the list. As stats are used during debugging, readability and clarity of the stats is vital in my opinion.

Output control is the role of testpmd, not the driver.
I think you can reorder the stats in testpmd given that you have defined
a clear scheme naming (thanks).

Add xstats() functions and statistic strings to virtio PMD.

Subject: [dpdk-dev] [PATCH v4 00/10] Port XStats
This patchset adds an implementation of the xstats_get() and xstats_reset()
API to the following PMDs: virtio, igb, igbvf, ixgbe, ixgbevf, i40e, i40evf and
fm10k.
The xstats API allows DPDK apps to gain access to extended statistics from
each port on a NIC. These statistics are structured as per a scheme detailed in
the patch for the doc/prog_guide.
v4: Consistency of names, refactored Q stat code
v3: Added more stats to PMDs
v2: Send correct patchset
doc: add extended statistics to prog_guide
ethdev: update xstats_get() strings and Q handling
virtio: add xstats() implementation
igb: add xstats() implementation

Harry,
Checkpatch is not happy because you missed the space after the keywords
"if" and "for".

Add extended statistic section to the programmers
guide, poll mode driver section. This section describes
how the strings stats are formatted, and how the client
code can use this to gather information about the stat.

+* detail 2
+* detail n
+* unit

+
+The scheme, although quite simple, allows flexibility in presenting and reading

+
+Some additions in the metadata scheme are as follows:
+
+* If the first part does not match ``rx`` or ``tx``, the statistic does not
+ have an affinity with either recieve of transmit.
+
+* If the first letter of the second part is ``q`` and this ``q`` is followed

Update the strings used for presenting stats to adhere
to the scheme previously presented. Updated xstats_get()
function to handle Q information only if xstats() is not
implemented in the PMD, providing the PMD with the needed

Hi Harry
If there are any apps today scraping the existing stats this will cause an issue.
I think the "good" description breaks the meaning of the various stats defined in the header. For example rx_packets is Total number of successfully received packets rather than the "good" packets.

Subject: [dpdk-dev] [PATCH v3 03/11] ethdev: update xstats_get()
strings and Q handling
Update the strings used for presenting stats to adhere to the scheme
previously presented. Updated xstats_get() function to handle Q
information only if xstats() is not implemented in the PMD, providing
the PMD with the needed flexibility to expose its extended Q stats.

Hi Harry
If there are any apps today scraping the existing stats this will cause an issue.
I think the "good" description breaks the meaning of the various stats defined
in the header. For example rx_packets is Total number of successfully
received packets rather than the "good" packets.

Maryam

{"rx_errors", offsetof(struct rte_eth_stats, ierrors)},

My bad, was quoting the wrong stats register... I'm happy with this change

Hi Harry,

We are planning on using the xstats API for periodic stats collection through a polling thread. This would be done in a generic NIC agnostic manner, which would require that the xstats identifiers have consistent naming amongst all of the NIC types. It would likely be polled several times per second and would only gather a subset of all available xstats types.

I have reviewed your patches and am interested in providing some API enhancements and bugfixes. Are you willing to provide feedback on such changes?

Thank you,
Tom

The whole point of xstats is to allow device specific statistics.
Consistent use of names is good from a user interface point of view, but probably
not a hard requirement.

[Tom Crugnale]

I understand. Is this the reason that that strings were used to identify the xstat types? An enum type would be much more efficient instead of doing string copies when retrieving the stats, but the number of enum entries would quickly grow out of control as device specific stats were added.

In this case, I'm actually referring to the stats that are common to all NICs. For example, for the received fragmented packets counter, there are three strings that identify this value: rx_fragment_packets (igb), rx_fragment_errors (ixgbe), rx_fragmented_packets (i40e).
I was thinking of making those names consistent. Perhaps the reason why they were different in the first place is that each of the device datasheets refers to these exact names.

[Kyle Larose]

Stephen,

Ultimately the issue we are trying to solve is that there is no device
independent way to get any detailed statistics from NICs controlled by
DPDK. These statistics are quite useful, not just for diagnostics, but
for long term reporting. People using DPDK-based NFV products in a
production environment are not going to be happy that they cannot, for
example, see how the packet size bucket counters varied over time
using some sort of monitoring tool.

The only alternative I can see to providing an API within DPDK is to
build our own abstraction layer triggered off the driver name/pci
ids/etc. I expect other people would end up doing this as well. This
seems like a waste of effort when an abstraction layer already exists
within DPDK.

So, let's consider solving the problem within DPDK. One option is to
use well-defined names for a given xstat that has the same semantics
across NICs, while continuing to allow NICs to expose any stats that
don't fall into this category.

Another option is to provide an API with a well-defined set of stats,
perhaps using an enum. In order for a stat to be added to this list,
it needs to be part of a standard (such as
http://tools.ietf.org/html/rfc2819).

Does anybody else see the need for something like this? We're more
than willing to do the work. We'd like to make sure we have the right
API, though.

Thanks,

Kyle

I don't understand.
The basic statistics are provided in a common API.
The other ones are not available in every NICs and can only be interpreted
while knowing the device. So what is the need exactly?
Do you know an example of a networking layer having this kind of API?

The need is to provide information to users about what sort of traffic
is being seen by the device, and why the hardware is behaving the way
it is, leveraging as much as possible the capabilities of the hardware
with minimal effort (i.e. not implementing an abstraction layer at a
higher level).

These are quite useful for diagnosing wider network issues
(configuration, misbehaving devices, dirty fibers/etc). The common API
doesn't expose the more detailed information requested by the various
ethernet mibs. Of course, not all stats are applicable to all devices
(e.g. collisions), but those that are available are still invaluable.

Post by Thomas Monjalon
Do you know an example of a networking layer having this kind of API?

I have worked with SDKs for a few different physical switches and
NPUs. They all provide this sort of API. I think it is quite common
with networking equipment such as routers or switches. These stats
tend to be exposed over SNMP at the very least, and often within local
utilities on the devices themselves.

Thanks,

Kyle

with minimal effort (i.e. not implementing an abstraction layer at a
higher level).
These are quite useful for diagnosing wider network issues
(configuration, misbehaving devices, dirty fibers/etc). The common API
doesn't expose the more detailed information requested by the various
ethernet mibs. Of course, not all stats are applicable to all devices
(e.g. collisions), but those that are available are still invaluable.

Thanks for the explanation.

Do you know an example of a networking layer having this kind of API?

I have worked with SDKs for a few different physical switches and
NPUs. They all provide this sort of API. I think it is quite common
with networking equipment such as routers or switches. These stats
tend to be exposed over SNMP at the very least, and often within local
utilities on the devices themselves.

So what is missing currently? Just having a consistent naming of
similar counters?

A consistent naming scheme would certainly solve the problem.

Thanks again,

Subject: Re: [dpdk-dev] [PATCH v3 00/11] Port XStats
Ultimately the issue we are trying to solve is that there is no device
independent way to get any detailed statistics from NICs controlled by
DPDK. These statistics are quite useful, not just for diagnostics, but
for long term reporting. People using DPDK-based NFV products in a
production environment are not going to be happy that they cannot, for
example, see how the packet size bucket counters varied over time
using some sort of monitoring tool.

Agreed, and that's what the xstats solves.

Post by Tom Crugnale
So, let's consider solving the problem within DPDK. One option is to
use well-defined names for a given xstat that has the same semantics
across NICs, while continuing to allow NICs to expose any stats that
don't fall into this category.

Yes, this is the aim of the current xstats also. As Tom Crugnale pointed
out, the current implementation has some variation in string names, however
the end-goal is to have consistent naming across NICs.

The scheme for naming stats is described in a doc patch, which was part
of my patchset: http://dpdk.org/dev/patchwork/patch/7906/

Ideally a script will automatically checks stats names against those of
other NICs, allowing switching of NICs and stats remaining consistent.

Given that each NIC is unique, this will require some organization work,
but it seems possible with some collaboration.

Post by Tom Crugnale
Another option is to provide an API with a well-defined set of stats,
perhaps using an enum. In order for a stat to be added to this list,
it needs to be part of a standard (such as
http://tools.ietf.org/html/rfc2819).

I would prefer see xstats gain wider support instead of discussing other
options.

[Harry van Haaren]

Add extended statistic section to the programmers
guide, poll mode driver section. This section describes
how the strings stats are formatted, and how the client
code can use this to gather information about the stat.

~~~~~~~~~~~~~~~~~~~

The Ethernet device API exported by the Ethernet PMDs is described in the *DPDK API Reference*.
+
+Extended Statistics API
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The extended statistics API allows each individual PMD to expose a unique set
+of statistics. The client of the API provides an array of
+``struct rte_eth_xstats`` type. Each ``struct rte_eth_xstats`` contains a
+string and value pair. The amount of xstats exposed, and position of the
+statistic in the array must remain constant during runtime.
+
+A naming scheme exists for the strings exposed to clients of the API. This is
+to allow scraping of the API for statistics of interest. The naming scheme uses
+strings split by a single underscore ``_``. The scheme is as follows:
+
+* direction
+* detail 1
+* detail 2
+* detail n
+* unit
+
+Examples of common statistics xstats strings, formatted to comply to the scheme
+proposed above:
+
+* ``rx_bytes``
+* ``rx_crc_errors``
+* ``tx_multicast_packets``
+
+The scheme, although quite simple, allows flexibility in presenting and reading
+information from the statistic strings. The following example illustrates the
+naming scheme:``rx_packets``. In this example, the string is split into two
+components. The first component ``rx`` indicates that the statistic is
+associated with the receive side of the NIC. The second component ``packets``
+indicates that the unit of measure is packets.
+
+A more complicated example: ``tx_size_128_to_255_packets``. In this example,
+``tx`` indicates transmission, ``size`` is the first detail, ``128`` etc are
+more details, and ``packets`` indicates that this is a packet counter.
+
+Some additions in the metadata scheme are as follows:
+
+* If the first part does not match ``rx`` or ``tx``, the statistic does not
+ have an affinity with either recieve of transmit.
+
+* If the first letter of the second part is ``q`` and this ``q`` is followed
+ by a number, this statistic is part of a specific queue.
+
+An example where queue numbers are used is as follows: ``tx_q7_bytes`` which
+indicates this statistic applies to queue number 7, and represents the number
+of transmitted bytes on that queue.

[Harry van Haaren]

Update the strings used for presenting stats to adhere
to the scheme previously presented. Updated xstats_get()
function to handle Q information only if xstats() is not
implemented in the PMD, providing the PMD with the needed
flexibility to expose its extended Q stats.

You're right - these stats are already available in the per-Q stats part of rte_eth_stats.
The virtio implementation of xstats is mostly framework code so we can add other
stats, for example packet size counters, in the near future.

Thanks for reviewing, -Harry

[Harry van Haaren]

Add xstats_get() and xstats_reset() functions to igb
driver, and the neccessary strings to expose these
NIC statistics.
