2021-03-25stats: python vpp_stats rewrite to access stat segment directlyOle Troan1-2/+2
This module implement Python access to the VPP statistics segment. It accesses the data structures directly in shared memory. VPP uses optimistic locking, so data structures may change underneath us while we are reading. Data is copied out and it's important to spend as little time as possible "holding the lock". Counters are stored in VPP as a two dimensional array. Index by thread and index (typically sw_if_index). Simple counters count only packets, Combined counters count packets and octets. Counters can be accessed in either dimension. stat['/if/rx'] - returns 2D lists stat['/if/rx'][0] - returns counters for all interfaces for thread 0 stat['/if/rx'][0][1] - returns counter for interface 1 on thread 0 stat['/if/rx'][0][1]['packets'] - returns the packet counter for interface 1 on thread 0 stat['/if/rx'][:, 1] - returns the counters for interface 1 on all threads stat['/if/rx'][:, 1].packets() - returns the packet counters for interface 1 on all threads stat['/if/rx'][:, 1].sum_packets() - returns the sum of packet counters for interface 1 on all threads stat['/if/rx-miss'][:, 1].sum() - returns the sum of packet counters for interface 1 on all threads for simple counters Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I1fe7f7c7d11378d06be8276db5e1900ecdb8f515 Signed-off-by: Ole Troan <ot@cisco.com>
2021-02-11tests: tag the tests that do not work with multi-worker configurationAndrew Yourtchenko1-0/+2
If the multi-worker default VPP configuration is triggered by setting VPP_WORKER_CONFIG="workers 2", some of the tests fail for various reasons. It's a substantial number, so this change marks all of the testsets that have this issue, such that they can be addressed later independently.

2020-10-07api: add heap alloc to vpp statsOle Troan1-1/+0
The Python VPP Stats module also used the VPP heap. Fix so it now explicitly allocates a heap. Fixes: f68fccfe7e188fec2c9f91da38ca9acf6f67d811 Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I0bd4ae64d6c89cdf634d8d9a91c23ab38017c5cc Signed-off-by: Ole Troan <ot@cisco.com>
2019-11-05misc: Fix python scripts shebang lineRenato Botelho do Couto1-1/+1
Type: fix Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python' as a valid shebang line. It requires scripts to explicitly chose between python2 or python3. Change all to use python3 as suggested by Paul Vinciguerra.

2019-06-18stats: fix memory leakage when adding / deleting interfacesOle Troan1-1/+18
This fixes two leaks in registering errors in the stats segment. - The error name created by vlib_register_errors() was not freed. - Duplicate error names (when interface readded) was added to the vector. This fix also adds memory usage statistics for the statistics segment as /mem/statseg/{used, total} Change-Id: Ife98d5fc5baef5bdae426a5a1eef428af2b9ab8a Type: fix Signed-off-by: Ole Troan <ot@cisco.com>
2019-05-22stats: support multiple works for error countersOle Troan1-0/+6
The current code only allowed access to the main thread error counters. That is not so useful for a multi worker instance. No return a vector indexed by thread of counter_t values. Type: fix Change-Id: Ie322c8889c0c8175e1116e71de04a2cf453b9ed7 Signed-off-by: Ole Troan <ot@cisco.com>
