[vpp-dev] ?????? ?????? ?????? ?????? How to get interface stats using C api?

2017-09-28 Thread ???????? 
Sorry, I do not know how to write a client. There is no documents which i can 
referece. I just know the steps which a client should have. But I do not know 
which functions to use. I would appricate it if you can write a draf client. I 
am studying 
  Yes, for study, I add some event apis int snat.

Looking at your code it seems you're not waiting for the reply at all. I
don't have experience with VAT and I don't think this is the recommended
way to write a client. Nevertheless, looking at your code, I don't see
any attempt to wait for a response. You are sending a message to VPP,
but not waiting for the reply nor the event.

Also I see that you are referencing VL_API_SNAT_DECRYPT_EVENT but I
don't see such event anywhere. Is this something which you added, but is
not committed yet?

Thank you very much! After reading this email, I understand the calling event 
api process. But in the step 3, i do not know call which function and how to 
call? In the test/ext/vapi_c_test.c, i can not find the function proto which in

There are new C and C++ APIs added recently to vpp source code along
with test programs. You can take a look at test/ext/vapi_c_test.c and
vapi_cpp_test.cpp. Functions receiving stats are named test_stats_XXX().
These are there to verify that receiving events works. Functionally,
these are the same, they just test different ways of doing stuff.

At shared memory level it looks like this:

1.) client -> want_stats -> vpp
2.) vpp -> want_stats_reply -> client (confirms subscription)
3.) vpp ->  -> client (when timer fires)

in step 3.), client needs to read the shared memory queue in the
vpp->client direction (or use the appropriate XXX_read() function). Note
that stats take a few seconds to arrive (the test programs require
10-15 seconds of runtime to get some stats).

HTH,
Klement

That is ok??
 Now I am research calling the plugin apis by C. Especially how to call the 
event apis. I would appreciate it if you can write a brief client.

Apologies,

It's a callback. 


We probably need some decent literature written for how to consume the various 
C, C++, Python and Lua APIs


If you have a preference for any of those languages I could write a brief 
client program for you and start work on documenting this stuff.

Hi there,

As of 17.10 you can now register for statistics on a per interface level.


You need the sw_if_index of the interface you want stats for, but the calls are 
in 
https://git.fd.io/vpp/tree/src/vpp/stats/stats.api



but as an example:
Register:
autoreply define want_per_interface_simple_stats {   u32 client_index;   u32 
context;   u32 enable_disable;   u32 pid;   u32 num;   u32 sw_ifs[num]; };
So calling "want_per_interface_simple_stats" with enable_disable=1, num=1 and 
sw_ifs[4] will give you interface_simple_stats every 10sec for sw_if_index=4.
The content of "interface_simple_stats" looks like:
/** \brief Simple per interface stats counters structure @param count - 
number of elements in message @param timestamp - u32 vlib timestamp for 
control plane @param data[count] - vl_api_vnet_simple_counter_t  */ 
manual_print manual_endian define vnet_per_interface_simple_counters {   u32 
count;   u32 timestamp;   vl_api_vnet_simple_counter_t data[count]; };
Where each "vnet_simple_counter_t" looks like:
https://git.fd.io/vpp/tree/src/vnet/interface.api
/** \brief Simple interface counter data type for 
vnet_interface_simple_counters @param sw_if_index - interface indexes for 
counters @param drop - RX or TX drops due to buffer starvation @param 
punt - used with VNET "punt" disposition @param rx_ip4 - received IP4 
packets @param rx_ip6 - received IP6 packets @param rx_no_buffer - no 
RX buffers available @param rx_miss - receive misses @param rx_error - 
receive errors @param tx_error - transmit errors @param rx_mpls - 
received MPLS packet */ typeonly manual_print manual_endian define 
vnet_simple_counter {   u32 sw_if_index;   u64 drop;   u64 punt;   u64 rx_ip4;  
 u64 rx_ip6;   u64 rx_no_buffer;   u64 rx_miss;   u64 rx_error;   u64 tx_error; 
  u64 rx_mpls; };
So you will get back an array of counter structs for each sw_if_index you 
registered for.
At the moment the impl sends on sw_if_index per reply but that is going to 
change so that for each client we send as much in one message as possible.
